    Full Text Available O fungo Ceratobasidium spp. é o agente causal da doença mal-do-fio ou queima-do-fio em várias plantas frutíferas, em cafeeiro e em chá. Esta doença ocorre com maior freqüência em zonas de alta precipitação e temperaturas elevadas, típicas de regiões de florestas tropicais como a Amazônica e a Mata Atlântica. Em São Paulo, o primeiro relato do mal-do-fio em caquizeiro ocorreu na região de Mogi das Cruzes. O objetivo deste estudo foi testar a patogenicidade cruzada de isolados de Ceratobasidium spp. de caquizeiro e chá para ambas as culturas e também para o cafeeiro e citros. Avaliou-se, também, a reação de oito cultivares de caquizeiro, sob condições controladas, a isolados de Ceratobasidium spp. obtidos da mesma cultura. Constatou-se que os isolados de caquizeiro e de chá, embora filogeneticamente distintos, foram patogênicos para ambas as culturas, além de afetarem cafeeiro e citros. Não foram verificados indícios de reação de resistência aos isolados de Ceratobasidium spp. para as oito cultivares de caquizeiro testadas.The fungus Ceratobasidium spp. causes the white-thread blight disease, which affects several fruit trees, coffee and tea crops. This disease frequently occurs in zones of high precipitation and temperatures, typical of the tropical forest regions such as the Amazon and the Atlantic Forests. In São Paulo State, Brazil, this disease was reported by the first time affecting kaki plants in Mogi das Cruzes county. The objective of this study was to test the cross-pathogenicity of Ceratobasidium spp. isolates from kaki and tea to both host plants and also to coffee and citrus. This study also aimed to determine the reaction of local kaki varieties to Ceratobasidium spp. isolates from kaki under controlled conditions. Although phylogenetically distinct, kaki- and tea-infecting isolates were cross-pathogenic to both hosts, besides infecting coffee and citrus. There was no indication of resistance reaction

    Full Text Available A cultura do caquizeiro vem crescendo em importância no Brasil e, com o aumento do cultivo, tem havido também incremento dos problemas relacionados a doenças e pragas. A pulverização de agrotóxicos é o método mais utilizado na prevenção e no controle desses problemas e a principal forma de aplicação é a pulverização hidráulica com auxílio de fluxo de ar. O objetivo deste trabalho foi avaliar o efeito da variação da taxa de aplicação e do repasse na parte interna das plantas em pulverização com pistola manual, na cobertura de calda das folhas. A pulverização foi realizada em plantas de caquizeiro com 17 anos, utilizando-se equipamento composto de trator e pulverizador turboatomizador. A aplicação foi realizada com duas velocidades de avanço do equipamento, o que promoveu diferentes taxas de aplicação. Para a realização do repasse, utilizou-se pistola manual acoplada ao mesmo equipamento. Para a avaliação da cobertura, utilizou-se calda preparada com corante fluorescente dissolvido em água. Foram coletadas folhas nas posições externa e interna das plantas. Posteriormente, em sala escura e com iluminação ultravioleta para destacar a área atingida pelo corante fluorescente, as superfícies abaxial e adaxial de cada folha foram fotografadas com câmera digital. Cada imagem gerada foi submetida à análise pelo software SIARCS 3.0, resultando em porcentagem de cobertura. O delineamento experimental utilizado foi de blocos ao acaso em parcelas subsubdivididas com quatro repetições, sendo os tratamentos arranjados em esquema fatorial (taxas alta e baixa de aplicação, com e sem repasse manual, localizações interna e externa da folha na planta. Foi avaliada a cobertura das superfícies abaxial e adaxial das folhas. Houve interação significativa entre tratamentos (taxa de aplicação e repasse manual, posição e superfície das folhas. A maior taxa de aplicação promoveu aumento significativo da cobertura

    We cloned and characterized Ty1-copia group retrotransposons in persimmon (Diospyros kaki Thunb.). Genomic DNA or methyl jasmonate (MJA)-treated cDNA were used as templates to amplify the reverse transcriptase region of Ty1-copia group retrotransposons. About 280 bp fragments were amplified and cloned, and 97 clones were sequenced. Forty-nine clones included frameshift or the stop codon, or both. Among 48 clones containing complete reading frames, 42 clones had unique nucleotide sequences. Alignment and phylogenetic analysis of putative amino acid sequences in the 42 clones indicated that these clones (named Tdk; retroTransposon in Diospyros kaki) fell into seven subgroups and six ungrouped sequences, indicating high sequence heterogeneity in Tdk clones. Phylogenetic analysis comparing unrelated plant species shows that some Tdk clones are more closely related to Ty1-copia group retrotransposons in the orders Solanales and Sapindales rather than to other Tdk clones. Southern blot analysis using Tdk2B, Tdk4c, Tdk6Ac, Tdk12K and Tdk13G clones as probes showed that persimmon and its related species, D. lotus, D. lotus var. glabba, D. oleifera, D. rhombifolia and D. virginiana, contained multiple Tdk-like sequences, indicating that homologous elements exist in other Diospyros species.

    Diabetic kidney disease is the most common and severe chronic complication of diabetes. The leaf of Diospyros kaki Thumb (persimmon) has been commonly used for herbal tea and medicinal purposes to treat a variety of conditions, including hypertension and atherosclerosis. However, the effect of persimmon leaf on kidney failure has not been investigated. This study aimed to examine the role of persimmon leaf in protecting the diabetes-associated kidney damage in a mouse model of type 2 diabetes. Mice were fed either a normal chow diet with or without powered persimmon leaf (5%, w/w) for 5 weeks. In addition to kidney morphology and blood markers of kidney function, we assessed levels of oxidative stress markers as well as antioxidant enzymes activities and mRNA expression in the kidney. Supplementation of the diet with powered persimmon leaf not only decreased the concentration of blood urea nitrogen in the plasma but also improved glomerular hypertrophy. Furthermore, the persimmon leaf significantly decreased the levels of hydrogen peroxide and lipid peroxide in the kidney. The activities of superoxide dismutase, catalase, and glutathione peroxidase and the mRNA expression of their respective genes were also increased in the kidney of persimmon leaf-supplemented db/db mice. Taken together, these results suggest that supplementation with the persimmon leaf may have protective effects against type 2 diabetes-induced kidney dysfunction and oxidative stress. PMID:28078262

    The ability of acidic (AcW) and alkaline electrolyzed waters (AlW) to improve the flavour of persimmon (Diospyros kaki L.) wine was evaluated. Wines made with AcW (WAcW) were significantly better than wines made with AlW or pure water (PW) in aroma, taste, and colour. Volatile analysis showed that WAcW has high alcohol and ester contents, including 2-phenylethanol, isopentanol, isobutanol, ethyl dodecanoate, phenethyl acetate, and butanedioic acid diethyl ester. The total amino acid content of persimmon slurry soaked with AcW reached 531.2 mg/l, which was much higher than those of the slurries soaked in AlW (381.3 mg/l) and PW (182.7 mg/l). The composition of major amino acids in the AcW-soaked slurry may contribute to the strong ester flavour of WAcW. This is the first report to suggest that electrolyzed functional water (EFW) can be used to improve wine flavour, leading to the possible use of EFW in food processing.

    Full Text Available Salinity continues to be a major factor in reduced crop productivity and profit in many arid and semiarid regions. Seedlings of Diospyros kaki Thunb. and D. virginiana L. are commonly used as rootstock in persimmon cultivation. In this study we have evaluated the effects of different salinity levels on photosynthetic capacity and plant development of D. kaki and D. virginiana. Salinity was provided by adding 50 mM, 75 mM and 100 mM NaCl to nutrient solution. In order to determine the effects of different salinity levels on plant growth, leaf number, plant height, shoot and root dry mass were recorded. Besides leaf Na, Cl, K and Ca concentrations were determined. Also leaf chlorophyll concentration, chlorophyll fluorescence (Fv’/Fm’ and leaf gas exchange parameters including leaf net photosynthetic rate (PN, stomatal conductance (gS, leaf transpiration rate (E, and CO2 substomatal concentration (Ci were investigated. Significant decrease of leaf number, shoot length and plant dry mass by increasing salinity levels was observed in both rootstocks. D. virginiana was less affected in terms of plant growth under salinity stress. Leaf chlorophyll concentration reduction was higher in the leaves of D. kaki in comparison to D. virginiana in 100 mM NaCl treatment. By increasing salinity levels PN, gS and E markedly decreased in both rootstocks and D. kaki was more affected from salinity in terms of leaf gas exchange parameters. In addition there was no significant difference but slight decreases were recorded in leaf chlorophyll fluorescences of both rootstocks.

    The feasibility of using the bio-photonic imaging technique to assess symptoms of circular leaf spot (CLS) disease in Diospyros kaki (persimmon) leaf samples was investigated. Leaf samples were selected from persimmon plantations and were categorized into three groups: healthy leaf samples, infected leaf samples, and healthy-looking leaf samples from infected trees. Visually non-identifiable reduction of the palisade parenchyma cell layer thickness is the main initial symptom, which occurs at the initial stage of the disease. Therefore, we established a non-destructive bio-photonic inspection method using a 1310 nm swept source optical coherence tomography (SS-OCT) system. These results confirm that this method is able to identify morphological differences between healthy leaves from infected trees and leaves from healthy and infected trees. In addition, this method has the potential to generate significant cost savings and good control of CLS disease in persimmon fields.

    Full Text Available This data article is related to the research article entitled, “Antioxidant potential in non-extractable fraction of dried persimmon (Diospyros kaki Thunb.” (Matsumura et al., 2016 [1]. We investigated antioxidant activities of the non-extractable fraction of dried persimmon fruits in vitro and in vivo. We evaluated both extracted fraction and non-extractable fraction, and reported that non-extractable fraction may possess significantly antioxidant potential in vivo on the basis of the oxygen radical absorbance capacity (ORAC. We showed our experimental raw data about antioxidant capacity of dried persimmon, plasma triglycerides (TG and HDL-cholesterol (HDL-C, and this data article might contribute to evaluate real antioxidant capacity of other fruits and vegetables.

    The pathological and physiological defects in various types of fruits lead to large amounts of economical waste. It is well recognized that internal fruit defects due to pathological infections and physiological disorders can be effectively visualized at an initial stage of the disease using a well-known bio-photonic detection method called optical coherence tomography (OCT). This work investigates the use of OCT for identifying the morphological variations of anthracnose (bitter rot) disease infected and physiologically disordered Diospyros kaki (Asian Persimmon) fruits. An experiment was conducted using fruit samples that were carefully selected from persimmon orchards. Depth-resolved images with a high axial resolution were acquired using 850-nm-based spectral-domain OCT (SD-OCT) system. The obtained exemplary high-resolution two-dimensional and volumetric three-dimensional images revealed complementary morphological differences between healthy and defected samples. Moreover, the obtained depth-profile analysis results confirmed the disappearance of the healthy cell layers among the healthy-infected boundary regions. Thus, the proposed method has the potential to increase the diagnostic accuracy of the OCT technique used in agricultural plantations.

    Persimmon (Diospyros kaki) is a seasonal fruit with important health benefits. In this study, persimmon use in wine and condiment production was investigated using molecular methods to identify the yeast and acetic acid bacteria (AAB) isolated from the alcoholic fermentation and acetification of the fruit. Alcoholic fermentation was allowed to occur either spontaneously, or by inoculation with a commercial Saccharomyces cerevisiae wine strain, while acetification was always spontaneous; all these processes were performed in triplicates. Non-Saccharomyces yeast species were particularly abundant during the initial and mid-alcoholic fermentation stages, but S. cerevisiae became dominant toward the end of these processes. During spontaneous fermentation, S. cerevisiae Sc1 was the predominant strain isolated throughout, while the commercial strain of S. cerevisiae was the most common strain isolated from the inoculated fermentations. The main non-Saccharomyces strains isolated included Pichia guilliermondii, Hanseniaspora uvarum, Zygosaccharomyces florentinus and Cryptococcus sp. A distinct succession of AAB was observed during the acetification process. Acetobacter malorun was abundant during the initial and mid-stages, while Gluconacetobacter saccharivorans was the main species during the final stages of these acetifications. Four additional AAB species, Acetobacter pasteurianus, Acetobacter syzygii, Gluconacetobacter intermedius and Gluconacetobacter europaeus, were also detected. We observed 28 different AAB genotypes, though only 6 of these were present in high numbers (between 25%-60%), resulting in a high biodiversity index.

    Full Text Available Ischemic cerebrovascular disease is one of the most common causes of death in the world. Recent interests have been focused on natural antioxidants and anti-inflammatory agents as potentially useful neuroprotective agents. Diospyros kaki (persimmon has been shown to exert anti-inflammatory, antioxidant, and antineoplastic effects. However, its effects on ischemic damage have not been evaluated. Here, we used an in vitro model of cerebral ischemia and studied the effects of hydroalcoholic extract of peel (PeHE and fruit pulp (PuHE of persimmon on cell viability and markers of oxidative damage mainly intracellular reactive oxygen species (ROS induced by glucose-oxygen-serum deprivation (GOSD in PC12 cells. GOSD for 6 h produced significant cell death which was accompanied by increased levels of ROS. Pretreatment with different concentrations of PeHE and PuHE (0–500 μg/mL for 2 and 24 h markedly restored these changes only at high concentrations. However, no significant differences were seen in the protection against ischemic insult between different extracts and the time of exposure. The experimental results suggest that persimmon protects the PC12 cells from GOSD-induced injury via antioxidant mechanisms. Our findings might raise the possibility of potential therapeutic application of persimmon for managing cerebral ischemic and other neurodegenerative disorders.

    Pancreatic lipase is the enzyme responsible for digestion and absorption of triglycerides, being its inhibition one of the widest studied methods used to determine the potential activity of natural products to inhibit dietary fat absorption. Decrease of energy intake from dietary fat through inhibition of this enzyme may be an excellent strategy to prevent and treat obesity. The inhibitory activity on pancreatic lipase enzyme of Diospyros kaki fruit and Citrus unshiu peel mixture extract (PCM) was evaluated in vitro and its antiobesity effects were studied based on the serum lipid parameters analysis from high-fat diet- (HFD-) fed mice in vivo. PCM was orally administered at a dose of 50 and 200 mg/kg body weight for 6 weeks. In addition, the activity of pancreatic lipase was assessed using orlistat (positive control). PCM exhibited inhibitory effect on lipase activity with IC50 value of 507.01 μg/mL. Moreover, serum triacylglycerol, total cholesterol levels, and visceral fat weight were significantly reduced compared to HFD control mice in PCM 200 mg/kg-treated mice (p < 0.05). These results suggest that PCM administration may be a novel potential antiobesity agent for reduction of fat absorption via inhibition of pancreatic lipase. PMID:27529064

    Purpose In this study, the beneficial effects of the oral administration of ethanol extract of Diospyros kaki (EEDK) were tested on a mouse dry eye model induced by benzalkonium chloride (BAC). Methods A solution of 0.2% BAC was administered topically to mouse eyes for 14 days, twice daily, to induce dry eye. Various concentrations of EEDK were administrated daily by oral gavage for 14 days after BAC treatment. Preservative-free eye drops were instilled in the positive-control group. The tear secretion volume (Schirmer’s test), tear break-up time (BUT), and fluorescein score were measured on the ocular surface. BAC-induced corneal damage was tested with hematoxylin-eosin staining. Moreover, apoptotic cell death in the corneal epithelial layer was investigated with terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The protein expression level of interleukin-1alpha (IL-1α), IL-1β, IL-6, tumor necrosis factor- alpha (TNF-α), and monocyte chemotactic protein-1 (MCP-1) was determined with western blot analysis. Furthermore, squamous metaplasia in the corneal epithelial layer was detected with immunofluorescent staining for cytokeratine-10. The cellular proliferation in the cornea was examined with immunohistochemical staining for Ki-67. Results EEDK treatment resulted in prolonged BUT, decreased fluorescein score, increased tear volume, and smoother epithelial cells compared with BAC treatment alone in the cornea. Moreover, EEDK treatment inhibited the inflammatory response and corneal epithelial cell death in a BAC-induced murine dry eye model, and changes in squamous cells were inhibited. Proliferative activity in the corneal epithelium cells was improved with EEDK. Conclusions EEDK could be a potential therapeutic agent in the clinical treatment of dry eye. PMID:27110091

    Full Text Available Tannins, plant-derived polyphenols and other related compounds, have been utilized for a long time in many fields such as the food industry and manufacturing. In this study, we investigated the anti-viral effects of tannins on 12 different viruses including both enveloped viruses (influenza virus H3N2, H5N3, herpes simplex virus-1, vesicular stomatitis virus, Sendai virus and Newcastle disease virus and non-enveloped viruses (poliovirus, coxsachievirus, adenovirus, rotavirus, feline calicivirus and mouse norovirus. We found that extracts from persimmon (Diospyros kaki, which contains ca. 22% of persimmon tannin, reduced viral infectivity in more than 4-log scale against all of the viruses tested, showing strong anti-viral effects against a broad range of viruses. Other tannins derived from green tea, acacia and gallnuts were effective for some of the viruses, while the coffee extracts were not effective for any of the virus. We then investigated the mechanism of the anti-viral effects of persimmon extracts by using mainly influenza virus. Persimmon extracts were effective within 30 seconds at a concentration of 0.25% and inhibited attachment of the virus to cells. Pretreatment of cells with the persimmon extracts before virus infection or post-treatment after virus infection did not inhibit virus replication. Protein aggregation seems to be a fundamental mechanism underlying the anti-viral effect of persimmon tannin, since viral proteins formed aggregates when purified virions were treated with the persimmon extracts and since the anti-viral effect was competitively inhibited by a non-specific protein, bovine serum albumin. Considering that persimmon tannin is a food supplement, it has a potential to be utilized as a safe and highly effective anti-viral reagent against pathogenic viruses.

Conhecer a forma como a planta utiliza esses carboidratos durante o seu desenvolvimento é um passo importante para o entendimento das suas relações fonte-dreno e para fundamentar algumas práticas de manejo, como a poda e o raleio de frutos. Caracterizar a variação dos teores de amido e de carboidratos solúveis totais em órgãos lenhosos do caquizeiro (Diospyros kaki L., no decorrer do seu desenvolvimento fenológico, foi o objeto de investigação do presente estudo. O trabalho foi conduzido em um pomar de caquizeiros localizado na área experimental da Escola Superior de Agricultura "Luiz de Queiroz" (ESALQ, em Piracicaba, Estado de São Paulo, durante o ciclo 2002/2003. A fenologia das plantas foi caracterizada pelo período de ocorrência e duração do alongamento dos ramos, florescimento, desenvolvimento dos frutos e das folhas e do abortamento natural de frutos. A variação dos teores desses carboidratos em ramos e em raízes foi analisada tendo por base os diferentes estádios fenológicos. Ocorreram variações significativas no teor desses carboidratos no período de estudo. A mobilização do amido nos ramos teve grande importância na sustentação de um novo ciclo de brotações. O maior consumo de amido ocorreu durante a abscisão foliar, e a reposição no seu estoque, nos ramos e nas raízes ocorreu, principalmente, entre o florescimento e a abscisão foliar.In deciduous fruit trees, the carbohydrate's metabolism are recognized as the main mechanism that ensures their survival during the rest period. Besides it, the very same metabolism is related to the productive potential in subsequent harvest seasons. Knowing how the plants use those carbohydrates during their development and growth is

    Full Text Available O objetivo deste trabalho foi avaliar o efeito do período de exposição ao vapor de álcool etílico na remoção da adstringência de frutos de caquizeiro (Diospyros kaki L. cultivar Giombo. Os frutos foram expostos ao vapor de álcool durante 24, 36 e 48 horas, sob temperatura de 20°C e 95% de umidade relativa. As características químicas e físicas dos frutos foram avaliadas durante dez dias, em intervalos de dois dias. As variáveis analisadas foram: teor de taninos solúveis, firmeza da polpa, perda de matéria fresca, pH, sólidos solúveis totais, acidez total titulável e teor de ácido ascórbico. De acordo com os resultados obtidos, os períodos de 24 e 36 horas demonstraram ser igualmente eficientes no processo de remoção da adstringência dos frutos; no entanto, a avaliação das demais características indicou melhor qualidade dos frutos expostos durante o período de 24 horas. Constatou-se uma diminuição linear na firmeza da polpa em função do tempo. O melhor período para consumo dos frutos situou-se entre o 4°e o 8° dia após o tratamento, considerando-se que a partir do 4° dia a concentração de taninos solúveis ficou abaixo de 0,1%, imperceptível ao paladar, e a firmeza da polpa dos frutos se manteve aceitável durante o período de oito dias posteriores ao tratamento.

    [Objective]This paper aims to isolate the cDNA of GA2ox from Diospyros kaki Linn. cv. Nantongxiaofangshi, and do some preliminary study on their functions and expression level, in order to lay a foundation for further exploration of the dwarf mechanism and breeding of new dwarf cultivars. [Method] Total RNA was extracted from leaves of ‘Nantongxiaofangshi’ persimmon by improved CTAB method. Two fragments were identified from cDNA of ‘Nantongxiaofangshi’ by degenerate primers, and their full length cDNA were acquired by RACE amplification and named as DkGA2ox1 and DkGA2ox2, respectively. Gene structure characteristics were analyzed using the bioinformatics software. Quantitative real-time PCR (qRT-PCR) was performed to determine the expression pattern during pre-budding period, budding period, leaf expanding period, tip buds dying period, flowering period, physiological fruit-falling period, fruit coloring period, fructescence and abscission period. [Result] The full length cDNA of DkGA2ox1 and DkGA2ox2 were 1 318 bp and 1 267 bp, respectively, containing 5′ untranslated region (UTR) with lengths of 198 bp and 61 bp, 3′ UTR with lengths of 97 bp and 172 bp, and coding region with lengths of 999 bp and 1 005 bp which encoded 332 and 334 amino acids. The two amino acid sequences shared 73%-77% in homology compared with Populus tomentosa (JX102472.1), oleander (AY594292.1), tobacco (AB125232.1), Petunia (GU059939.1), apple (FJ571521.1), pears (JF441168.1) and grapes (JQ608472.1). The conserved structural domain analysis revealed that DkGA2ox1 and DkGA2ox2 had the typical functional domains of GA2ox protein, containing Fe2+ binding sites (DkGA2ox1: His-205, Asp-207, His-262; DkGA2ox2: His-204, Asp-206, His-261) and 2-oxoglutarate binding sites (DkGA2ox1: Arg-272, Ser-274; DkGA2ox2: Arg-271, Ser-273), as well as the 2OG-Fe(II)-Oxy protein domains. The protein molecular weights were 36 596.1 Da and 37 544.2 Da, respectively. Both of them are stable proteins

    Six quinones were isolated from the chloroform extract of the roots of Diospyros sylvatica and identified as 2-methyl-anthraquinone, plumbagin, diosindigo, diospyrin, isodiospyrin and microphyllone. The effect of the root extract on the orientation and survival of the subterranean termite, Odontotermes obesus was tested. In addition, four of these quinones were tested on the survival of the subterranean termite. In a direct-choice experiment, exposure to an extract-treated filter disc had a significantly repellent effect over the solvent-treated filter disc. The no-choice experiment revealed the toxic property of the extract as well as the tested quinones and showed high mortality of the O. obesus workers after 48 h on forced exposure. The major termiticidal components identified were plumbagin, isodiospyrin and microphyllone while diospyrin was not toxic to termites at the concentration tested. All the quinones are reported for the first time from D. sylvatica.

    Carotenoid pigments were extracted and purified from persimmon fruits using accelerated solvent extraction (ASE). Eleven pigments were isolated and five of them were clearly identified as all-trans-violaxanthine, all-trans-lutein, all-trans-zeaxanthin all-trans-cryptoxanthin and all-trans-β-carotene. Absorption and fluorescence spectra were recorded. To evaluate the potential of ¹O₂ quenching of the purified carotenoids, we used a monocarboxylic porphyrin (P1COOH) as the photosensitizer to produce ¹O₂. The rate constants of singlet oxygen quenching (Kq) were determined by monitoring the near-infrared (1270 nm) luminescence of ¹O₂ produced by photosensitizer excitation. The lifetime of singlet oxygen was measured in the presence of increasing concentrations of carotenoids in hexane. Recorded Kq values show that all-trans-β-cryptoxanthin, all-trans-β-carotene, all-trans-lycopene and all-trans-zeaxanthin quench singlet oxygen in hexane efficiently (associated Kq values of 1.6 × 10⁸, 1.3 × 10⁸, 1.1 × 10⁸ and 1.1 × 10⁸ M(-1)·s(-1), respectively). The efficiency of singlet oxygen quenching of β-cryptoxanthin can thus change the consideration that β-carotene and lycopene are the most efficient singlet oxygen quenchers acting as catalysts for deactivation of the harmful ¹O₂.

    Full Text Available Selection of suitable pollinizers is very important for persimmon that have a widespread problem in fruit setting. This study aims to contribute for solving this problem. Study was carried out in 2010 vegetation period with 17 years old persimmon trees in Adana conditions. For this purpose, the suitability of Bruniquel and Ghora Gali pollinizer cultivars were searched for 9 local persimmon types (07TH05, 07TH06, 07TH13, 07TH14, 07TH17, 31TH01, 31TH02, 31TH03 and 33TH01. In laboratory tests of pollen viability, germination and quantity, it was determined that the potential of Ghora Gali and Bruniquel is satisfactory for a pollinizer. With controlled-pollination treatments, fruit drop was reduced compared with open pollination and non-pollination treatments. In terms of this, the best pollinator for 07TH14 and 33TH01 was Bruniquel and for 07TH06 and 07TH17 it was Ghora Gali. Both Bruniquel and Ghora Gali became suitable pollinators for 07TH05. In 07TH13, 31TH02 and 31TH03 genotypes, the best results were obtained from open pollination treatments. At the same time, 07TH14 and 33TH01 genotypes have high affinity to parthenocarpy because of their fruit set ability while there is not any pollinizer.

    The optimal conditions for sulfation of polysaccharides from persimmon fruits (PFP) with chlorosulfonic acid-pyridine (CSA-Pyr) method were determined by response surface methodology. Box-Behnken design was applied to evaluate the effects of three independent variables (volume ratio of Pyr to CSA, volume ratio of PFP to SO(3)Pyr and reaction time) on the degree of substitution (DS), molecular weight (MW) and activated partial thromboplastin time (APTT) of sulfated polysaccharides (PFP-S). The APTT activity of PFP-S could be improved by application of various volume ratio of Pyr to CSA, volume ratio of PFP to SO(3)Pyr and reaction time, which was possible due to the degradation of polysaccharides to different extent and increasing of DS. The optimal conditions to obtain the strongest APTT of PFP-S were the volume ratio of CSA to Pyr of 1:8, the volume ratio of SO(3)Pyr to PFP of 1:3.6 and the reaction time of 3 h, respectively.

    Full Text Available Objetivou-se avaliar, com o presente trabalho, o efeito da temperatura e do CO2 no armazenamento em atmosfera controlada sobre a conservação de caqui cv. Quioto. Foram avaliadas as temperaturas -1,0 e -0,5ºC, e pressões parciais de CO2 de 0; 5 e 10kPa, com os tratamentos arranjados em um esquema bifatorial. Os frutos foram avaliados após 3 meses de armazenamento mais 3 dias de exposição à temperatura ambiente (18-20ºC. Conforme os resultados, não foi constatada interação entre os fatores, havendo efeito significativo para temperatura somente na firmeza de polpa, em que -1,0ºC apresentou frutos mais firmes. As diferentes pressões parciais de CO2 não influenciaram a perda de peso e a firmeza de polpa. As podridões apresentaram uma resposta linear negativa em relação ao CO2, porém, mantendo elevada ocorrência. Valores de CO2 entre 5 e 10kPa proporcionaram frutos com menor índice de escurecimento de epiderme e com coloração mais amarela e vermelha. O CO2 entre 5 e 10kPa apresentou os melhores resultados, que somados à temperatura de -1,0ºC, foi a melhor condição de armazenamento, que, no entanto, teve o período de conservação inferior a três meses nesta condição, devido às altas perdas por podridões.

    Full Text Available Abstract Aim Diospyros Lotus (“Wild Date Palm of Trabzon or Persimmon”, which has been proven to cause phytobezoars, is a widely consumed fruit in the Black Sea and Northeast Anatolia regions of Turkey. The aim of the present study was to investigate the effects of Diospyros Lotus together with other predisposing factors, on the development of gastrointestinal phytobezoars and to discuss the treatment results in comparison to the literature. Material and method The records of 13 patients, who had been admitted to the General Surgery Clinic of Düzce Atatürk State Hospital between August 2008 and August 2011, were retrospectively reviewed. Demographic characteristics, predisposing factors, clinical and radiological findings, diagnostic and therapeutic methods, and the outcomes of the patients were recorded from the patient files. Written informed consent was obtained from each patient for publication of this research article and accompanying images. Results All the patients had a history of consuming Diospyros Lotus. Of the patients, 30,7% had a history of previous gastric surgery, 30,7% had diabetes mellitus and 23% had dental implants. None of the patients had hypothyroidism, which is another predisposing factor for phytobezoars. The phytobezoars were located in the stomach alone in 23% of the patients, whereas 15,3% was detected in the jejunum and stomach, 15,3% was detected in the jejunum alone, and 46,1% was detected in the ileum alone. All patients were treated with surgery, and there were no deaths. Conclusion Gastric phytobezoars are rare. Preventive measures have particular importance in the management of this condition, which is difficult to treat. For this purpose, excessive consumption of herbal nutrients containing a high amount of indigestible fibers such as Diospyros Lotus should be avoided in patients with a history of gastrointestinal surgery or poor oral and dental health.

    Full Text Available O objetivo deste trabalho foi o estabelecimento de um protocolo para a embriogênese somática do caquizeiro. Como explantes, foram utilizados embriões zigóticos em diversos estádios de desenvolvimento, retirados de frutos coletados de plantas adultas a campo, a partir de quatro semanas após o pleno florescimento até 22 semanas. O meio básico para os experimentos foi o MS½NO3. O meio inicial de indução foi suplementado com 20µM de 2,4-D e 2µM de cinetina. Os calos escuros obtidos foram repicados para outro meio de indução, com concentrações 10 ou 20 µM de 2,4-D e 2 µM de cinetina. Os calos com massas pró-embriogênicas obtidos foram transferidos para meio de manutenção e multiplicação com 2 µM de cinetina e 2,4-D nas concentrações 2,5; 5,0 e 10 µM. As massas embriogênicas formadas foram transferidas para meio de maturação suplementado com 0,5 µM de AIB e as concentrações 5; 10 e 20 µM de 2-iP. Os embriões formados foram isolados em dois meios de conversão, sendo o primeiro com 5 µM de 2-iP, 5 µM de AG3 e 0,5 µM de AIB e o segundo com 0,5 µM de AG3 e BAP, nas concentrações 0; 0,25; 0,5 e 1,0 µM. Como resultados, obteve-se o padrão indireto de embriogênese somática a partir de embriões zigóticos maduros, com mais de 22 semanas de formação, quando cultivados em meio de cultura com 10 µM de 2,4-D combinado com 2 µM de cinetina. A manutenção e a multiplicação das culturas embriogênicas foram mais eficientes com 5 µM de 2,4-D, na qual os pró-embriões avançaram para o estádio globular.

    Full Text Available Pedagang kaki lima identik dengan kesan buruk, kotor dan tidak tertib. Penempatan sarana perda­gangan yang tidak teratur dan tidak tertata serta sering menempati tempat yang menjadi tempat umum dianggap sebagai penyebab kondisi tersebut. Tingginya minat konsumsi masyarakat menyebabkan pedagang kaki lima menjadi semakin banyak, terutama masyarakat kelas bawah. Melalui Perda Nomor 11 Tahun 2000, Pemerintah Kota Semarang sudah berusaha menata PKL. Namun pada kenyataannya belum ditemukan solusi yang komprehensif untuk mengatasi permasalahan PKL. Populasi penelitian ini adalah PKL Perumnas Tlogosari Kota Semarang berjumlah 173 pedagang. Sampel yang digunakan berjumlah 100 orang sebagian besar berasal dari luar kawasan Perumnas Tlogosari. Model PKL di PerumTlogosari mengunakan Pola Penyebaran Memanjang (Linier Concentration. Hasil penelitian menunjuk­kan bahwa sebelum ada penataan tidak ada paguyuban. Namun setelah penataan terdapat sebuah paguyuban pedagang dan jasa (PPJ, dalam bentuk arisan. Dampak sosial selain paguyuban adalah agenda rutin arisan, serta peraturan lainnya sehingga meninimalkan konflik yang timbul. Dari sisi ekonomi, sebagian besar pedagang mengalami peningkatan pendapatan yang diperoleh per bulan. Oleh karena itu, untuk menjaga keberlanjutan dari dampak positif yang timbul, diharapkan PKL mampu menjaga dan melaksanakan aturan yang telah disepakati bersama, sekaligus melakukan inovasi-inovasi agar barang yang dijual lebih bervariatif untuk memperoleh keuntungan berkesinambungan.Street vendors usually have bad impression because they are dirty and disorderly.

    Objective: To evaluate pharmacologically the traditional use of Diospyros lotus as antipyretic and antinociceptive in various animal models.Methods: In vivo experimental models were used in this study. Antipyretic activity of extract/fractions was evaluated in brewer’s yeast induced hyperthermic mice while antinociceptive activity was studied in acetic acid induced writhing test at 50 and 100 mg/kg i.p.Results:The crude extract strongly ameliorated the induced pyrexia during various assessment times. Upon fractionation, the antipyretic effects were strongly augmented by the chloroform and ethyl acetate fractions of the plant. However, hexane and butanol fractions were insignificant in their effect as antipyretic. The extract showed marked inhibition on the noxious simulation induced by post acetic acid injection. The effect was strongly supported by other fraction expect hexane.Conclusions:In short, our study scientifically validated the traditional use of the plant as antipyretic.

    The persimmon fruit is a particularly good model for studying fruit response to hypoxia, in particular, the hypoxia-response ERF (HRE) genes. An anaerobic environment reduces fruit astringency by converting soluble condensed tannins (SCTs) into an insoluble form. Although the physiology of de-astringency has been widely studied, its molecular control is poorly understood. Both CO(2) and ethylene treatments efficiently removed the astringency from 'Mopan' persimmon fruit, as indicated by a decrease in SCTs. Acetaldehyde, the putative agent for causing de-astringency, accumulated during these treatments, as did activities of the key enzymes of acetaldehyde synthesis, alcohol dehydrogenase (ADH), and pyruvate decarboxylase (PDC). Eight DkADH and DkPDC genes were isolated, and three candidates for a role in de-astringency, DkADH1, DkPDC1, and DkPDC2, were characterized by transcriptional analysis in different tissues. The significance of these specific isoforms was confirmed by principal component analysis. Transient expression in leaf tissue showed that DkPDC2 decreased SCTs. Interactions of six hypoxia-responsive ERF genes and target promoters were tested in transient assays. The results indicated that two hypoxia-responsive ERF genes, DkERF9 and DkERF10, were involved in separately regulating the DkPDC2 and DkADH1 promoters. It is proposed that a DkERF-DkADH/DkPDC cascade is involved in regulating persimmon de-astringency.

    Full Text Available O comércio de caqui fresco resulta em grande quantidade de frutos nãoclassificados. Assim, considerando também que a desidratação prolonga a vida-de-prateleira de alimentos perecíveis, a pesquisa se propôs a fazer uma contribuição para o desenvolvimento do processo de fabricação de passa a partir de frutos de caqui ‘Fuyu’. Foi utilizado um secador contendo circulação forçada de ar e cinco bandejas. O fruto descascado foi fatiado em quatro formas diferentes: fatias em metades, de corte transversal; fatias em ¼, de cortes longitudinais; fatias em ¼, de corte longitudinal seguido de corte transversal; fatias em 1/8, de dois cortes longitudinais seguidos de transversais. A condição de secagem que aplicou temperatura de 80°C por 1h seguida de 60°C por cerca de 23h produziu passas de caqui ‘Fuyu’ com a melhor aparência. A forma da fatia passa que teve a preferência dosprovadores foi aquela em que o fruto foi cortado em oito fatias (fatias de 1/8. As passas de caqui ‘Fuyu’ contendo umidades residuais baixas, 19,7 e 27,4%, foram apreciadas, quanto ao paladar, igualmente pelos provadores. Os frutos de caqui proporcionaram, em peso, 16,7 e 18,1% de produtos em passas e perdas estimadas em 25,5%. Os resultados indicaram que a passa de caqui ‘Fuyu’ constitui-se numa excelente oferta de fruta desidratada.Because kakis are usually sold fresh, this results in a high number of fruits that do not meet the marketing standard. Thus, considering that dehydration extends the shelf life of perishable foods, this research was aimed at providing a contribution for the development of a product referred to as dehydrated ‘Fuyu’ kaki. A forced air circulation dehydrator was used, equipped with five trays. The peeled fruit was sliced in four different ways: sliced into halves, transversally; sliced into quarters, longitudinally; sliced into quarters, once longitudinally and once transversally; sliced into eighths, by cutting twice

Diospyros consists of over 300 species spread throughout tropics area and about 100 species occur in Indonesia. Bisbul wood (Diospyros btancoi A.DC. is one species of  streaked ebony that is locally known as 'buah mentega'.  The anatomical and physical properties of  bisbul  were studied to collect information  for wood identification  and to support appropriate use of the timber. Anatomical properties were studied from microtome sectioned samples, which have been coloured by safranin and mounted by entellan, while fiber dimensions  were studied from macerated samples.  Physical properties  of  bisbul wood studied include moisture content, density and percentage of volumetric shrinkage. Moisture content and density were studied from 20 x 20 x 20 mm samples based on wet and oven dry condition. Volumetric shrinkage was measured from dimension changes in radial, tangential and longitudinal shrinkage of 20 x 20 x 40 mm samples. The samples were measured in wet and oven dry conditions. The main anatomical characteristics to identify bisbul wood were black wood with pinkish streaked, heavy and very hard,  very fine texture, even, lustrous surface and glossy, distinct growth ring, small size of vessels, apotracheal parenchyma forming reticulate pattern. The average moisture content was 59.86 ± 2.84%,  the density average was 0.74 ± 0.04 gr/cm3  and volumetric shrinkage was 10.41±0.70%.   The higher the stem, the more moisture  content and the lower the density will be.

    Since the discovery and subsequent widespread use of antibiotics, a variety of bacterial species of human and animal origin have developed numerous mechanisms that render bacteria resistant to some, and in certain cases to nearly all antibiotics, thereby limiting the treatment options and compromising effective therapy. In the present study, the green synthesis of nanoparticles is carried out by the reduction of silver acetate in the presence of crude methanolic root extracts of Diospyros paniculata, a member of family Ebenaceae. The UV–Vis absorption spectrum of the biologically reduced reaction mixture showed the surface plasmon peak at 428 nm, a characteristic peak of silver nanoparticles. X-ray diffraction (XRD) analysis confirmed the face-centered cubic crystalline structure of metallic silver. The average diameter of Ag NPs is about 17 nm from Transmission Electron Microscopy (TEM) which is in good agreement with the average crystallite size (19 nm) calculated from XRD analysis. Further the study has been extended to the antimicrobial activity against test pathogenic Gram (+), Gram (−) bacterial and fungal strains. The biologically synthesized silver nanoparticles showed promising activity against all the tested pathogenic strains and the activity has been enhanced with the increased dose levels. - Highlights: • Biosynthesis of silver nanoparticles (Ag NPs) using root extracts of Diospyros paniculata. • Average diameter of Ag NPs is about 17 nm from TEM analysis which is in good agreement with XRD analysis. • Antimicrobial activities of root extract mediated synthesis of silver Ag NPs were discussed in detail.

    The dissipation of residue levels of captan and trichlorfon in field-treated kaki crops was studied according to good laboratory practices to propose maximum residue limits (MRLs). Residue levels of captan and trichlorfon were analysed by GC/MS and LC-MS/MS, respectively. Residue levels of captan and trichlorfon permitted one to propose MRLs in kaki of 3 and 5 mg kg(-1), respectively. The behaviour of these residues was also studied after peeling and cooking, and in individual fruits versus composite samples. Residue levels of these compounds for individual fruits suggested that a variability factor up to three could be set for the acute risk assessment. Levels of captan decreased by more than 90% after peeling and completely after cooking. Trichlorfon penetrates into the flesh in a proportion of 70% of the residue at the pre-harvest interval. Cooking resulted in a decrease of 27% of residue levels of trichlorfon.

Based on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical scavenging activities, DBSB showed (95.760 ± 0.343)%and (67.460 ± 2.641)%scavenging with IC50 of (3.10 ± 0.17) and (50.00 ± 3.11) mg/mL, respectively. The IC50 values of standard butylated hydroxytoluene and catechin (CA) for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were (8.50 ± 0.25) and (75.00 ± 0.14) mg/mL, respectively suggesting that DBSB had a significant (P DBRB > CA > DBL. Also, the phenolic [(139.91 ± 3.924) mg gallic acid equivalent/g] and flavonoid contents [(412.00 ± 16.70) mg catechin equivalent/g)] of DBSB were higher than that of other extracts. In addition, the DBSB showed the moderate cytotoxic and anticancer properties. Conclusions: Our results indicate that Diospyros blancoi stem bark had the significant highest antioxidant and free radical scavenging properties as well as moderate anticancer activity. Hence, we assume that the anticancer activity of this plant can be, at least in part, attributed to its content in phenolic compounds as well as its significant free radical scavenging properties.

    Objective:To isolate and characterize the cytotoxic compounds from Diospyros quercina (Baill.) G.E. Schatz&Lowry (Ebenaceae). Methods: An ethno-botanical survey was conducted in the south of Madagascar from July to August 2010. Bio-guided fractionation assay was carried out on the root bark of Diospyros quercina, using cytotoxicity bioassay on murine P388 leukemia cell lines as model. The structures of the cytotoxic compounds were elucidated by 1D and 2D NMR spectroscopy and mass spectrometry. Results: Biological experiments resulted in the isolation of three bioactive pure compounds (named TR-21, TR-22, and TR-23) which exhibited very good in vitro cytotoxic activities with the IC50 values of (0.017 5±0.0060) µg/mL, (0.089±0.005) µg/mL and (1.027±0.070) µg/mL respectively. Thus, they support the claims of traditional healers and suggest the possible correlation between the chemical composition of this plant and its wide use in Malagasy folk medicine to treat cancer. Conclusions:The ability of isolated compounds in this study to inhibit cell growth may represent a rational explanation for the use of Diospyros quercina root bark in treating cancer by Malagasy traditional healers. Further studies are, therefore, necessary to evaluate the in vivo anti-neoplastic activity of these cytotoxic compounds as effective anticancer drugs.

    Crude decoction, aqueous and ethanolic extracts of two medicinal plants (Psidium guajava and Diospyros mespiliformis), widely used in the central plateau of Burkina Faso to treat many diseases were evaluated for their antagonistic effects on caffeine induced calcium release from sarcoplasmic reticulum of rat skeletal muscle cells. These different extracts showed a decrease of caffeine induced calcium release in a dose dependent manner. Comparison of the results showed that Psidium guajava leaf extracts are more active than extracts ofDiospyros mespiliformis and that crude decoctions show better inhibitory activity.The observed results could explaine their use as antihypertensive and antidiarrhoeal agents in traditional medicine, by inhibiting intracellular calcium release.

    This study was conducted to quantitatively evaluate the antioxidant, antihemolytic and nephroprotective effects of Diospyros lotus seeds extract in experimental in vitro and in vivo models. Antioxidant potential of Diospvyos lotus seeds extract was examined by employing seven in vito models i.e., DPPH, nitric oxide and hydrogen peroxide radicals scavenging activity, iron ion chelating, reducing power and lipid peroxidation through linoleic acid. Antihemolytic activity of extract was examined against hydrogen peroxide-induced erythrocytes hemolysis. Also, nephroprotective effect of extract against gentamicin (GM)-induced renal injury was evaluated. Renal injury was achieved by injecting 100 mg/kg, intraperitoneally (i.p.) of GM in normal saline. Extracts were administrated i.p. in doses 200 and 400 mg/kg. Blood samples were examined for serum creatinine and blood urea nitrogen after 10 consecutive days of treatment. Results show that extract showed different level of antioxidant and antihemolytic activity in the studied models. Also, results show that GM-induced nephrotoxic animal model was successfully constructed. Extract attenuated the gentamicin-induced increase in level of serum creatinine and blood urea nitrogen. The present study shows that the extract offered significant biological action compared with standard compound.

    Full Text Available Mucilage was isolated from the seeds of Diospyros melonoxylonRoxb., a plant growing naturally in the forests of India. Various physico-chemical methods like particle analysis, scanning electron microscopy, differential scanning calorimetry, differential thermal analysis, thermogravimetry analysis, molecular weight by gel permeation chromatography, rheometry, elemental analysis, x-ray diffraction spectrometry, zeta potential, fourier transform infrared spectroscopy, 1D(1H and 13C (NMR have been employed to characterize this gum in the present study. Particle analyses suggest that mucilage had particle size in nanometer. SEM analysis suggested that the mucilage had irregular particle size. The glass transition temperature of the gum observed was 78 °C and 74 °C by DSC and DTA respectively. The Thermogravimetry analysis suggested that mucilage had good thermal stability with two stage decomposition. The molecular weight of mucilage was determined to be 8760, by gel permeation chromatography, while the viscosity of mucilage was observed to be 219.1 cP. The XRD pattern of the mucilage indicated a complete amorphous nature. Elemental analysis of the gum revealed specific contents of carbon, hydrogen, nitrogen and sulfur. The major functional groups identified from FT-IR spectrum include 3441 cm-1 (-OH, 1632 cm-1 (-COO-, 1414 cm-1 (-COO- and 1219 cm-1 (-CH3CO.

    Diospyros lotus L. is traditionally used in various diseases including pain and sleep disorders. The pain and inflammation are the common problems, which are treated with various synthetic analgesic drugs, and associated the side effects. The natural products have gained significant importance over synthetic drugs. The importance of phyto-medicine the current study has been designed with the aim to investigate the analgesic and anti-inflammatory effects of Diospyros lotus and bioassay guided isolation from its crude fractions. Seven known compounds; lupeol (1), 7-methyljuglone (2), β-Sitosterol (3), stigmasterol (4) betulinic acid (5), diospyrin (6; DS) and 8-hydroxyisodiospyrin (7; HDS) which were hitherto unreported from D. lotus. The chloroform fraction (CFDL) and isolated compounds DS and HDS were evaluated for anti-nociceptive, sedative and anti-inflammatory effects. The acetic acid induced writing was significantly (pHDS (65.76%) at higher doses which exhibited peripheral and central analgesic effects in acetic acid and hot-plat pain paradigms. Regarding the anti-inflammatory effect the CFDL (77.43%), DS (80.54%) and HDS (75.87%) protected the carrageenan paw edema after 3rd h. The central analgesic effect was significantly antagonized with naloxone (0.5 mg/kg), showing opiodergic mechanism of action. The CFDL, DS and HDS were also proved sedative in open field animal models. In acute toxicity study the chloroform fraction [CFDL (50, 100 and 150 mg/kg)], DS (5 and 10 mg/kg) and HDS (5 and 10 mg/kg) were found safe. Our study concluded that CFDL, DS and HDS have marked anti-nociceptive, anti-inflammatory and sedative effect. The anti-nociceptive and anti-inflammatory effects of the roots of D. lotus are partially attributed due to the presence of analgesic constituents like diospyrin (DS), 8-hydroxyisodiospyrin (HDS) and strongly supports the ethno-pharmacological uses of D. lotus as anti-nociceptive, anti-inflammatory and sedative.

    Full Text Available We screened the aqueous and methanol leaf and root extracts of Anthocleista djalonensis, Diospyros mespiliformis, and their combinations for possible anti-mycobacterial activities using Mycobacterium smegmatis as a surrogate screen. These plants are reputed among folk practices as potent remedy in the management of tuberculosis and leprosy cases. In the sensitivity screening study, only the methanol extracts of A. djalonensis and D. mespiliformis showed anti-mycobacterial activity, while the aqueous extracts exhibited no inhibitory activity on M. smegmatis. The minimum inhibitory concentration (MIC of the methanol leaf and root extract of A. djalonensis against M. smegmatis were 125 μg/ml. The MIC of the methanol leaf and root extracts of D. mespiliformis is 167 and 250 μg/ml, respectively. In the interaction studies, four out of nine decimal combinations of the two medicinal plant extracts exhibited synergism with fractional inhibitory concentration indices < 1 and a negative activity index values. The 8:2 ratio of D. mespiliformis and A. djalonensis exhibited the greatest degree of antimycobacterial synergy against M. smegmatis. The result of this study supports the claims of efficacy reported in the folk use of these plants in mycobacterial infection and the plants could therefore be investigated further and harnessed as potent antimycobacterial agents.

    The aim of this study was to investigate the protective effect of Diospyros lotus (DL) on cisplatin (CP)-induced testicular damage in male rats. Twenty-eight male rats were randomly divided into four groups: group 1 - control, given isotonic saline solution; group 2 - CP 7 mg kg(-1) given intraperitoneally as single dose; group 3 - DL 1000 mg kg(-1) per day given orally for 10 days; group 4 - CP and DL given together at the same doses. CP caused a significant increase in thiobarbituric acid-reactive substances (TBARS) level and a significant decrease in superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione (GSH) levels in rats testis tissues compared to the control group. CP caused a significant increase in lipid peroxidation in testis tissues compared to the control group, whereas DL led to a significant increase in SOD and GSH levels. However, there were no statistically significant changes in GPx and CAT levels. In addition, serum testosterone levels, sperm concentration and sperm motility were significantly decreased, but abnormal sperm rate and histological changes were increased with CP. However, these effects of CP on sperm parameters, histological changes and the tissue weights were eliminated by DL treatment. In conclusion, our study showed that the reproductive toxicity caused by CP may be prevented by DL treatment.

    Full Text Available Os parâmetros aerodinâmicos de uma cultura cultivada em ambiente protegido podem ser considerados dependentes do nível de radiação global, temperatura do ar e umidade do ar, com base em leis exponenciais. Assim sendo se propôs com este trabalho, estimar a evapotranspiração e o coeficiente de cultivo da cultura do tomate caqui em ambiente protegido, sob irrigação por gotejamento, utilizando-se o modelo de Penman-Monteith. Os parâmetros aerodinâmicos foram medidos com sensores conectados à estação automática instalada dentro do ambiente protegido. A evapotranspiração da cultura (ETc foi determinada experimentalmente por meio de lisímetros de drenagem e a umidade do solo foi medida através de sensores instalados a uma profundidade de 20 cm. O desempenho do modelo de Penman-Monteith foi comparado aos valores decendiais do balanço hídrico nos lisímetros; já a evapotranspiração de referência foi calculada com dados externos e utilizada para o cálculo do Kc da cultura; enfim, os resultados indicaram que o modelo de Penman-Monteith subestima os valores de evapotranspiração encontrados pelo balanço hídrico nos lisímetros.The aerodynamic parameters of a crop cultivated in greenhouse can be considered dependent upon the level of global radiation, air temperature and relative humidity, based on exponential laws. Consequently, this work intends to estimate the evapotranspiration and the crop coefficient of Kaki tomato in greenhouse, under drip irrigation, using the Penman-Monteith model. The aerodynamic parameters were measured with sensors connected to the automatic station installed inside the greenhouse. The ETc was determined experimentally through drainage lysimeters and the soil water content was measured through sensors installed at a depth of 20 cm. The performance of the Penman-Monteith model was compared to decennial values of the water balance in the lysimeters, while the reference evapotranspiration was calculated

    This paper presents the advances made over the last decade in cryopreservation of economically important vegetatively propagated fruit trees. Cryopreservation protocols have been established using both dormant buds sampled on field-grown plants and shoot tips sampled on in vitro plantlets. In the case of dormant buds, scions are partially dehydrated by storage at -5 °C, and then cooled slowly to -30 °C using low cooling rates (c.a. 1 °C/h) before immersion in liquid nitrogen. After slow rewarming and rehydration of samples, regrowth takes place either through grafting of buds on rootstocks or excision of apices and inoculation in vitro. In the case of shoot tips of in vitro plantlets, the cryopreservation techniques employed are the following: controlled rate cooling procedures involving slow prefreezing followed by immersion in liquid nitrogen or vitrification-based procedures including encapsulation-dehydration, vitrification, encapsulation-vitrification and droplet-vitrification. The current status of cryopreservation for a series of fruit tree species including Actinidia, Diospyros, Malus, Olea, Prunus, Pyrus and Vitis is presented. Routine application of cryopreservation for long-term germplasm storage in genebanks is currently limited to apple and pear, for which large cryopreserved collections have been established at NCGRP, Fort Collins (USA), using dormant buds and in vitro shoot tips, respectively. However, there are a growing number of examples of pilot scale testing experiments under way for different species in various countries. Progress in the further development and application of cryopreservation techniques will be made through a better understanding of the mechanisms involved in the induction of tolerance to dehydration and cryopreservation in frozen explants.

    Deoxypreussomerin derivatives, palmarumycins JC1 (1) and JC2 (2), and two dimeric naphthoquinones, isodiospyrin (3) and its new derivative isodiospyrol A (4), were isolated from dried fruits of Diospyros ehretioides. Structures of the isolated compounds were elucidated by spectroscopic analyses. Palmarumycins were not found in the extract of freshly collected fruits; however, they were present in dried fruit extract. The absence of palmarumycins in fresh fruits of D. ehretioides, together with the chemotaxonomic point of view, we proposed that palmarumycins JC1 (1) and JC2 (2) are more likely to be fungal metabolites, i.e., endophytes or epiphytes. The isolation of palmarumycins 1 and 2 from dried D. ehretioides fruits could be reproducible; both plant samples collected in the years 2002 and 2004 provided the same result, and, therefore, symbiont fungal strains should be specific to the plant host, D. ehretioides, and they can grow on the fruits during drying the sample. Palmarumycin JC1 (1) did not exhibit antimalarial, antifungal, antimycobacterial, and cytotoxic activities. Palmarumycin JC2 (2) exhibited antimalarial (IC50 4.5 microg/ml), antifungal (IC50 12.5 microg/ml), antimycobacterial (MIC 6.25 microg/ml), and cytotoxic (IC50 11.0 microg/ml for NCI-H187 cell line) activities. In our bioassay systems, isodiospyrin (3) did not exhibit antimycobacterial, antifungal, antimalarial, and cytotoxic activities. Isodiospyrol A (4) exhibited antimalarial (IC50 2.7 microg/ml) and antimycobacterial (MIC 50 microg/ml) activities, but was inactive towards Candida albicans. Compound 4 also exhibited cytotoxicity against BC cells (IC50 12.3 microg/ml), but not towards KB and Vero cell lines.

    Full Text Available The persimmon culture can be attacked by several pests and diseases, however, there are few studies related to the control. In addition, there is a lack of pesticides registered in the Ministry of Agriculture, Livestock and Supply (MAPA, in Portuguese “Ministério da Agricultura, Pecuária e Abastecimento”, emerging the fruit bagging as an alternative. The aim of this study was to evaluate different kinds of protective packs for bagging persimmon fruits, in order to control pests and diseases and, consequently, improve the fruit quality. The experiment was conducted in a persimmon orchard on the experimental station of the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul (IFRS, located in the Tuiuty District, in Bento Gonçalves, RS. Were performed four treatments: control (not bagged fruits, perforated polypropylene packaging, white TNT (non woven tissue packing, and kraft brown paper packing. The harvested fruits were evaluated for weight, symptoms of caterpillars damage, presence of mealybug (Pseudococcus sp. and symptoms of Schyzothyrium pomi. The fluctuation population of Anastrepha fraterculus was performed using McPhail trap with hydrolyzed protein. Among the treatments, only the fruits protected with perforated polypropylene differ significantly from the control on the evaluations of weight and Schyzothyrium pomi symptoms. However, there was no significant difference on the damage caused by caterpillars and presence of mealybugs. The use of perforated polypropylene has demonstrated efficiency on the control of Anastrepha fraterculus, and it can be used to reduce the damage in the fruits.

    The changes of photochemical quenching(qp) and non-photochemical quenching(qN) of chlorophyll a fluorescence in leaves of four tree seedlings ( Gleditsia sinensis, Juglans regia, Diospyros kaki and Diospyros lotus ) were different between two different water stress ways:detached drought treatment and potted drought treatment. After 4 hours dehydration by leaf detaching,the qp values had significant decrease except J. regia, only 6 hours later, the qp values compared with contrast decreased significantly in four tree seedlings(P>0.05), but the range of reduction( G.sinensis, J.regia and D.lotus) was just 2.5% to 6.4%. D.kaki, however,got to 31.3%. While the qN values increased significantly with conducting dehydration of the detached leaves. However, the qp values of four species showed no significant decrease when they were growing in pots under soil water stress(40%~60% RWC) for 30 days; and the qN values decreased obviously with a exception in J. regia, which was consistent with that of detached leaf treatment. The results suggested that some difference or changes in mechanism of excess light energy dissipation might perform in four seedlings by short-term and long-term water stress.

    Full Text Available Footwear can be categorized as one of labour intensive and very superior export commodities, consequently the product quality must be maintained and be continually improved. The quality parameter of footwear is determined by the bonding strength between the uppers and the soles, it means that it depends on the adhesive applied. Soling system is widely applied in small and medium industries are cemented system used synthetic adhesive. Now, the adhesive was applied in the manufacturing of foot wear supported by binding of the soles and the uppers is easy to peel off because of the poor bonding strength. The aim of the research was to investigate a suitable synthetic adhesive formula to used in footwear manufacturing. In preparing of the adhesive formula, the effect of phenolic resin addition as tackifier were varies i.e 35, 45 and 55 phr using chloroprene rubber as raw material were observed. Synthetic adhesive compound was produce by two roll mill after that compound were dissolved in toluene with ratio 1 : 3. The prepared adhesive then was applied to manufacture footwear using cool press system. The soles used in the experiment were made of rubber and plastic material whereas the uppers made of either leather or artificial leather. The test result and data analysis showed that adhesive performed for the highest bonding strength as much as 1000 g/cm and decrease to lowest bonding strength after soaking in to water for 500 seconds one percent was obtained by the following formula that were : chloroprene rubber 100 phr, butylated hydroxyl toluene 2 phr, magnesium oxide 4 phr, zinc oxide 5 phr and phenolic resin 45 phr. The prepared formula performed a better bonding strength when it was compared with chloroperene rubber adhesive in market.

    Two novel acetic acid bacteria, strains G5-1(T) and I5-1, were isolated from traditional kaki vinegar (produced from fruits of kaki, Diospyros kaki Thunb.), collected in Kumamoto Prefecture, Japan. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains G5-1(T) and I5-1 formed a distinct subline in the genus Gluconacetobacter and were closely related to Gluconacetobacter swingsii DST GL01(T) (99.3% 16S rRNA gene sequence similarity). The isolates showed 96-100% DNA-DNA relatedness with each other, but <53% DNA-DNA relatedness with closely related members of the genus Gluconacetobacter. The isolates could be distinguished from closely related members of the genus Gluconacetobacter by not producing 2- and 5-ketogluconic acids from glucose, producing cellulose, growing without acetic acid and with 30% (w/v) d-glucose, and producing acid from sugars and alcohols. Furthermore, the genomic DNA G+C contents of strains G5-1(T) and I5-1 were a little higher than those of their closest phylogenetic neighbours. On the basis of the phenotypic characteristics and phylogenetic position, strains G5-1(T) and I5-1 are assigned to a novel species, for which the name Gluconacetobacter kakiaceti sp. nov. is proposed; the type strain is G5-1(T) (=JCM 25156(T)=NRIC 0798(T)=LMG 26206(T)).

    Cytological mechanisms of 2n pollen formation in ‘Zenjimaru' nonastringent persimmon (Diospyros kaki L.f. ) were studied. The following abnormalities in meiosis were found to be responsible for the production of 2n pollens: (1) disoriented spindles, including parallel, fused and tripolar spindles, were formed at metaphase Ⅱ and anaphase Ⅱ; (2) the nuclei at telophase Ⅱ were arranged to two poles, each of which contained two nuclei, or to three poles, one of which contained two nuclei, the other two contained one nucleus respectively; (3) dyads and triads were produced at the tetrad stage. The dyad would develop into two 2n pollens, and the triad would develop into one 2n and two n pollens. The 2n pollens produced by this mechanism were genetically equivalent to FDR (first division restitution) gametes, thus providing a potential value for sexual polyploidization.

Nesse particular, pode-se aquilatar a dificuldade para o melhorista realizar tais testes, pois um grupo de caquis taninosos mascara o paladar de duas ou três amostras subseqüentes. Daí a necessidade de desenvolver um processo de análise indireta, a exemplo do presente, que consiste no tratamento da polpa dos frutos com a solução de cloreto férrico.

Fruits are usually harvested unripe and classified as to the astringency level in tasting tests: constant "shibugaki", variable "shibugaki"/ "amagaki" and absence of astringency "amagaki". As misleading results have been obtained in tasting tests, an indirect procedure has been proposed to evaluate tannin levels in persimmon flesh. It is based on a color scale (dark blue/dark gray - astringent type; brown - variable astringency, and light gray-absence of astringency, detected after the application of 0.1 N iron chloride solution on persimmon flesh. The new method has shown good precision, allowing determination of a great number of samples in a short period of time.

    The extraction of carotenoids from Japanese persimmon peels by supercritical fluid extraction (SFE), of which the solvent was CO(2), was performed. In order to enhance the yield and selectivity of the extraction, some portion of ethanol (5 - 20 mol%) was added as an entrainer. The extraction temperature ranged from 313 to 353 K and the pressure was 30 MPa. The effect of temperature on the extraction yield of carotenoids was investigated at 10 mol% of the ethanol concentration in the extraction solvent, and a suitable temperature was found to be 333 K among the temperatures studied with respect to the carotenoid yield. With increasing the entrainer amount from 0 to 10 mol% at a constant temperature (333 K), the carotenoid yield in the extraction was improved, whereas the selectivity of the extracted carotenoids was drastically depressed. We also conducted qualitative and quantitative analyses for the carotenoid components in the extract by HPLC, and analyzed the extraction behavior of each individual carotenoid (alpha-carotene, beta-carotene, beta-cryptoxanthin, lycopene, lutein, and zeaxanthin). The selectivity of each carotenoid changed with the elapsed time and its time evolution was dependent on the carotenoid component, indicating that the location profile and the content can be important factors to understand the SFE behavior of each carotenoid in persimmon peels.

    Hexane, ethylacetate (EtOAC), and n-butanol (n-BuOH) extracts of medicinal plants traditionally used in the East Asia, such as China, Korea, and Japan were screened for their vasorelaxant activity using isolated rat aorta. Among the 60 solvent-extracts from 20 medicinal plants, hexane and n-BuOH extracts of Diospyros kaki and Polygonum aviculare, hexane, EtOAC, and n-BuOH extracts of Magnolia liliflora, n-BuOH extract of Sorbus commixta, and EtOAC and n-BuOH extracts of Selaginella tamariscina were found to exhibit distinctive vasorelaxant activity. The activity disappeared by removal of functional endothelium or pre-treatment of the aortic tissues with N(G)-nitro-L-arginine methyl ester (L-NAME), which is an inhibitor of nitric oxide synthase. These findings suggest that the medicinal plants relax vascular smooth muscle via endothelium-dependent nitric oxide. These results will be useful to further analyze those medicinal plants that contain the vasorelaxant activity in order to identify the active principles.

    Full Text Available A predatory insect, Chrysopa sinica Tiedet (Neuroptera: Chrysopidae, and its taxis behavior were investigated in a tritrophic system that included a herbivore, Ceroplastes japonicus Green (Hemiptera: Coccidae, and a host plant, persimmon tree, Diospyros kaki L. (Ebenaceae. The results showed that this predator was attracted to the volatile compounds of persimmon trees that were infested with C. japonicus; however, the attraction varied with the growth season of the trees and the development stage of the wax scale. The strongest attraction occurred in the autumn and not in the late spring or summer. For the four time periods considered throughout the day, the most significant attraction rates were found at midnight and the early afternoon. The results indicated that the transformation of the chemical compositions of the volatiles of the persimmon tree might drive the taxis response of the predator in the three studied seasons. We mainly found differences in terpenoid emissions and propose that these compounds play a key part in the observed differences in attractiveness.

    The regulation of postharvest treatment with propylene and 1-MCP on ethylene release rate and expressions of 1-aminocyclopropane-1-carboxylic acid synthase (ACS) and 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) genes in Fuping Janshi persimmon (Diospyros kaki L.) fruit were investigated. Fruits were treated with propylene and 1-MCP, then stored at 20℃, ethylene release rate of the treated fruits was measured at regular intervals and RNA was extracted for Northern blotting analysis. The results suggested that treatment with propylene accelerated the expressions of ACS and ACO genes and then enhanced the ethylene biosynthesis, while treatment with 1-MCP inhibited the expressions of two genes and their ethylene biosynthesis. Furthermore, different effects on expressions caused by treatments with propylene and 1-MCP existed in various fruit tissues, the inhibitory effect on ACS and ACO genes by 1-MCP was the strongest in pericarp, followed by pulp and core tissues, in the area near fruit stalk, the inhibitory effect was the weakest. While the enhanced effect on ACS and ACO genes by propylene increased from pulp, core, and pericarp to the area near fruit stalk. Expression of each member of ACS and ACO families in various tissues was also completely different, in control and propylene treatment, DKACS3 gene just expressed in the area near fruit stalk and did not express in other tissues, but DKACS2 gene expressed in four tissues by treatment with propylene.

    Effects of basal mediums, hormones and their concentrations on the shoot regeneration from leaf of sweet persimmon (Diospyros kaki Thunb. Cv. Uenishiwase) were studied by orthogonal design trial. The result showed that modified Murashige and Skoog [MS (1/2 N)] was the most optimum for the regeneration and 1/2 MS was better than MS. Shoot percentage in the medium containing 4.0 mg L-1 ZT(zeatin) was much higher than that of other two concentrations, among which 2.0 mg L-1 ZT was much better than 1.0 mg L-1 ZT and shoot percentage in the concentration of 1.0 mg L-1 ZT was only 4%. There were no any beneficial effects when supplementing IAA in the medium. Shoot percentage and average shoots perexplantsweredramaticallydecreasedinthe 2.0 mg L-1 IAA. Data in the orthogonal trial indicated that ZT was the most effective factor in the shoot regenerating of Uenishwase persimmon and basal medium was important too, but IAAhad no any beneficial effects at all. In the orthogonal trial, the best result was achieved in MS (1/ 2 N) medium containing 4.0 mg L-1 ZT and 1.0 mg L-1 IAA, in which shoot percentage and average shoots per explants were 86% and 2.2, respectively.

    China lacks large scale authorized epidemiological study results in allusion to subarachnoid hemorrhage (SAH) within recent 15 years since MONICA (multinational monitoring of trends and determinants in cardiovascular disease) study revealed SAH situation in China in 2000. The main cause of SAH in China is aneurysm which takes up 30-50%, while over 90% aneurysm locates at Willis circle. Early surgery for SAH after aneurysm rupture is the dominant procedure to deal with SAH in China. Moreover, calcium antagonists rank the absolute leading position for cerebral vascular spasm (CVS) among medication-based treatment options. However, traditional Chinese medicine such as Salvia miltiorrhiza, Acanthopanax senticosus, Ginkgo biloba, Pueraria lobata, Liguisticum chuanxiong, cow bezoar, Diospyros kaki and Gynostemma pentaphyllum have been proven beneficial in CVS prevention and treatment, while Salvia miltiorrhiza and TCM soup have unique effects on bleeding absorption. In addition, aescine and some TCM soup might relieve strong headache after SAH. In general, TCM integrated with western medicine have shown unique advantages in the current treatment of SAH in China. However, it is a pity that China still lacks larger scale randomized controlled trials and research on SAH treatment focusing on TCM and the related mechanism of TCM on SAH still need to be investigated further.

    Activity of polyphenol oxidase (PPO) from "Rojo Brillante" persimmon (Diospyros kaki L.) fruits was characterized. Crude extracts were used for characterization of enzyme activity and stability at different temperatures (60, 70 and 80 °C), pHs (from 3.5 to 7.5) and substrate concentrations (catechol from 0 to 0.5M). Maximum enzyme activity was reached at pH 5.5 and 55 °C. Enzyme stability was higher than PPO activities found in other natural sources, since above pH 5.5 the minimum time needed to achieve an enzyme inactivation of 90% was 70 min at 80 °C. However, at pH 4.0 the enzyme stability decreased, reaching inactivation levels above 90% after 10 min even at 60 °C. Thus it was concluded that acidification can circumvent browning problems caused by PPO activity. Moreover, polyacrylamide gel electrophoresis of the enriched extract revealed the presence of at least four bands with strong oxidase activity, suggesting the existence of different PPO isoforms.

    Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

    This study evaluated the effects of two Korean traditional plant extracts (Diospyros kaki THUNB. leaf; DK, and Nelumbo nucifera leaf; NN) on the fermentation, functional and sensory properties of herbal yogurts. Compared to control fermentation, all plant extracts increased acidification rate and reduced the time to complete fermentation (pH 4.5). Supplementation of plant extracts and storage time were found to influence the characteristics of the yogurts, contributing to increased viability of starter culture and phenolic compounds. In particular, the increase in the counts of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus was highest (2.95 and 1.14 Log CFU/mL respectively) in DK yogurt. Furthermore, supplementation of the plant extracts significantly influenced to increase the antioxidant activity and water holding capacity and to produce volatile compounds. The higher antioxidant activity and water holding capacity were observed in NN yogurt than DK yogurt. Moreover, all of the sensory characteristics were altered by the addition of plant extracts. Addition of plant extracts increased the scores related to flavor, taste, and texture from plain yogurt without a plant extract, as a result of volatile compounds analysis. Thus, the overall preference was increased by plant extracts. Consequently, supplementation of DK and NN extracts in yogurt enhanced the antioxidant activity and physical property, moreover increased the acceptability of yogurt. These findings demonstrate the possibility of using plant extracts as a functional ingredient in the manufacture of herbal yogurt.

    Various plant species of green belt in urban traffic area help to reduce air pollution and beautify the city environment. Those plant species growing healthily under long-term atmospheric pollution environment are considered to be resilient. This study aims to identify plant species that are more tolerant to air pollution from traffic and to give recommendations for future green belt development in urban areas. Leaf samples of 47 plant species were collected from two heavy traffic roadside sites and one suburban site in Beijing during summer 2014. Four parameters in leaves were separately measured including relative water content (RWC), total chlorophyll content (TCH), leaf-extract pH (pH), and ascorbic acid (AA). The air pollution tolerance index (APTI) method was adopted to assess plants' resistance ability based on the above four parameters. The tolerant levels of plant species were classified using two methods, one by comparing the APTI value of individual plant to the average of all species and another by using fixed APTI values as standards. Tolerant species were then selected based on combination results from both methods. The results showed that different tolerance orders of species has been found at the three sampling sites due to varied air pollution and other environmental conditions. In general, plant species Magnolia denudata, Diospyros kaki, Ailanthus altissima, Fraxinus chinensis and Rosa chinensis were identified as tolerant species to air pollution environment and recommend to be planted at various location of the city, especially at heavy traffic roadside.

A concentração de 1-MCP utilizada nos tratamentos específicos foi de 500ppb/2h. As principais análises realizadas compreenderam: firmeza da polpa (FP, cor e escurecimento de epiderme (EE. Os caquis do experimento 2 perderam a qualidade de comercialização antes de alcançarem os 30 dias de estocagem. O uso de AM associada à refrigeração manteve frutos com FP acima de 40 N, além de prevenir a ocorrência de EE, após 48 dias de armazenamento mais 10 dias de CS. A obtenção destes índices proporcionou a manutenção da qualidade dos caquis por 48 dias de câmara mais 10 dias de CS no ar ambiente (18°C.With the objective of to extend the conservation period and commercialization of the 'Fuyu' persimmon fruit, alternatives to mantain fruits quality were tested. Tree experiments were accomplished to develop the work: 1 storage at the ambient temperature (AT: Temperature (T of 18 ± 3°C and relative humidity (RH of 80 ± 5%, with or without application of 1-MCP and evaluated in the crop, at 7 and 14 days; 2: cold storaged (CS: T of 0 ± 1,0°C and RH of 95 ± 5%, with or without application of 1-MCP, appraised in the crop and 45 + 3 days of simulated commercialization; and 3 CS and modified atmosphere (MA with films of polyethylene of low density (PELD with 80mm of thickness: T of 0 ± 1,0°C and RH of 95 ± 5%, with or without application of 1-MCP, appraised in the crop, 48 of CS and 10 days of simulated commercialization. The concentration of 1-MCP used in the specific treatments was of 500ppb/2h. The main physiochemical analyses accomplished were: pulp firmness (PF, color and epidermis browning (EB. The persimmon fruits of the experiment 2, maintained in CS, lost the commercialization quality before reaching 30 days of storage. The use of MA associated to CS, maintained the fruits with PF above 40 N, besides preventing the occurrence of EB. The yielded results showed that the maintenance of persimmon fruits quality can be kept for 48 days at CS and more 10 days of simulated commercialization at the environment temperature.

    Unlike the typical climacteric fruits,persimmons (Diospyros kaki Thunb.) produce higher levels of ethylene when they are detached from trees at a younger stage.In order to obtain detailed information on the role of abscisic acid (ABA) in ripening,we cloned the DKNCED1,DKACS2,and DKAC01 genes from the calyx.Water loss was first noted in the calyx lobe,and DKNCED1 was highly expressed 1 d after the fruits were detached,coinciding with an increase in the ABA content.Then,the DKACS2 and DKAC01 genes were expressed after some delay.In the calyx,the ABA peak was observed 2 d after the fruits were harvested,and this peak preceded the ethylene peak observed on day 3.The fruit firmness rapidly decreased on day 4,and the fruits softened completely 6 d after they were harvested.The increases in the expressions of ABA,ethylene,and the genes in the calyxes occurred earlier than the corresponding increases in the pulp,although the 3 increases occurred on different days.Exogenous ABA treatment increased ABA concentration,induced expression of both ACS and ACO,and promoted ethylene synthesis and young-fruit softening;by contrast,treatment with NDGA inhibited the gene expressions and ethylene synthesis and delayed young-fruit softening.These results indicate that ethylene biosynthesis in the detached young persimmon fruits is initially triggered by ABA,which is induced by water loss in the calyx,through the induction of DKACS2 and DKAC01 expressions.The ethylene produced in the calyx subsequently diffuses into the pulp tissue,where it induces autocatalytic ethylene biosynthesis,resulting in an abrupt increase in ethylene production.

    Full Text Available Population fluctuations of the Mediterranean fruit fly (medfly, Ceratitis capitata, were investigated between 1999 and 2001 at several locations representing fruit production areas in the southern part of Syria (Damascus Ghota, Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab. Medfly adults were monitored weekly all year around using Jackson traps baited with trimedlure dispensers. Larvae were also sampled in Damascus Ghota by collecting fruits from ripe or ripening fruit trees and recording the number of larvae emerged from these fruits. In addition, suspected overwintering refuges were sampled at weekly intervals during the three coldest months of the year (December – February and the number of collected larvae was recorded. The results of trap catches and fruit sampling studies showed a similar pattern of occurrence of medfly populations in the study areas, particularly in Damascus Ghota, during the three years of the study. In Damascus Ghota, flies were caught continuously from early June to late December with some variability between years. Two distinct periods of high fly activity were observed: the first one occurred in August and the second in November with a much higher amplitude. In general, seasonal fluctuations in the pattern of occurrence were influenced by differences in temperature and abundance of preferred host fruits. Traps on fig Ficus carica and oriental persimmon Diospyros kaki trees caught the highest numbers of flies, and fruits collected from these trees showed the highest level of infestation, reaching 100% for fig fruit late in the season. Sampling fruits (in Damascus Ghota from trees during the three coldest months of the year showed that a small population of medfly larvae was able to survive winter conditions in prickly pear Opuntia vulgaris fruit left on the trees. In the other areas of the study (Zabadani, Sargaiah, Rankus, Orneh and Ain Al-Arab, only a few flies were caught.

    By tracking the fate of individual seeds from 6 frugivore-dispersed plants with contrasting seed traits in a fragmented subtropical forest in Southwest China, we explored how rodent seed predation and hoarding were influenced by seed traits such as seed size, seed coat hardness and seed profitability. Post-dispersal seed fates varied significantly among the 6 seed species and 3 patterns were witnessed: large-seeded species with a hard seed coat (i.e. Choerospoadias axillaries and Diospyros kaki var. silvestris) had more seeds removed, cached and then surviving at caches, and they also had fewer seeds predated but a higher proportion of seeds surviving at the source; medium-sized species with higher profitability and thinner seed coat (i.e. Phoebe zhennan and Padus braohypoda) were first harvested and had the lowest probability of seeds surviving either at the source or at caches due to higher predation before or after removal; and small-seeded species with lower profitability (i.e. Elaeocarpus japonicas and Cornus controversa) had the highest probability of seeds surviving at the source but the lowest probability of seeds surviving at caches due to lower predation at the source and lower hoarding at caches. Our study indicates that patterns of seed predation, dispersal and survival among frugivore-dispersed plants are highly determined by seed traits such as seed size, seed defense and seed profitability due to selective predation and hoarding by seed-eating rodents. Therefore, trait-mediated seed predation, dispersal and survival via seed-eating rodents can largely affect population and community dynamics of frugivore-dispersed plants in fragmented forests.

    Full Text Available Illegal rosewood logging has known a strong increase in 2009, following two inter-ministerial texts legalizing exports of precious wood. National parks are specifically affected by this exploitation. It is of course very difficult to know the real situation concerning exploitation but also exports. This paper presents and discusses information about “illegal” exports. Firstly, after a recall of the legal context, it underlines the difficulties in collecting information. Several reasons are underlined: the size of container, the density of wood, the diversity of material (log, board, etc, the place of shipment, the filling up of containers, and under-declaration for fiscal reasons. Nevertheless, even if exports estimations are probably far from the reality, the equivalent of around 1,202 containers, representing a value of more than US$ 220,000,000 are listed. Secondly, it analyzes also traffic regulation systems. More specifically, it proposes a parallel between the regulation of ivory traffic and the regulation of precious wood traffic in Madagascar. It concludes that the process of garnishment with resale by auction has very few chances to be efficient. The ivory case shows that reinforcing processes of garnishment do not succeed in stopping the traffic. It rather provokes reorganizations of the value chain. In the long term, the sole solution will be the development of a sustainable labeled chain for precious wood. European Union Due Diligence Regulation and Lacey Act in United States participate in the strengthening of control on precious wood.

    Full Text Available The lipoxygenase (LOX pathway is a key regulator for lipid peroxidation, which is crucial for plant senescence and defence pathways. In this study, the transcriptional expression patterns of three persimmon (Diospyros kaki L. ‘Fupingjianshi’ 9-lipoxygenase genes (DkLOX1, DkLOX3 and DkLOX4 were investigated. DkLOX1 was specifically expressed in fruit, particularly in young fruit, and showed little response to the postharvest environments. DkLOX4 was expressed in all tissues and slightly stimulated by mechanical damage and low temperature. DkLOX3 was expressed mainly in mature fruit, and the expression was extremely high throughout the storage period, apparently up-regulated by mechanical damage and high carbon dioxide treatments. Further functional analysis showed that overexpression of DkLOX3 in tomato (Solanum lycopersicum cv. Micro-Tom accelerated fruit ripening and softening. This was accompanied by higher MDA content and lycopene accumulation, advanced ethylene release peak and elevated expression of ethylene synthesis genes, including ACS2, ACO1 and ACO3. In addition, DkLOX3 overexpression promoted dark induced transgenic Arabidopsis leaf senescence with more chlorophyll loss, increased electrolyte leakage and MDA content. Furthermore, the functions of DkLOX3 in response to abiotic stresses, including osmotic stress, high salinity and drought were investigated. Arabidopsis DkLOX3-OX transgenic lines were found to be more tolerant to osmotic stress with higher germination rate and root growth than wild-type. Moreover, DkLOX3-OX Arabidopsis plants also exhibited enhanced resistance to high salinity and drought, with similar decreased O2- and H2O2 accumulation and upregulation of stress-responsive genes expression, including RD22, RD29A, RD29B and NCED3, except for FRY1, which plays a negative role in stress response.

    2014-07-01

    Radiocesium ({sup 137}Cs) concentrations in persimmon tree tissues collected at Chiba, about 220 km south from Fukushima Daiichi nuclear power plant (FDNPP), were measured to obtain half-life of radiocesium in the trees. Persimmon (Diospyros kaki) is a deciduous tree and bears edible fruits in autumn. There were no leaves when the sampling area was received the radioactive fallout in March 2011 due to the FDNPP accident; the amount of {sup 137}Cs radioactivity in this area was ca. 13 kBq/m{sup 3} Both {sup 137}Cs and {sup 134}Cs were found in the newly emerged shoots of the persimmon trees collected at 26 April 2011 mainly due to foliar uptake. The concentrations were 1.1 kBq/kg-dry for {sup 137}Cs and 1.3 kBq/kg-dry for {sup 134}Cs. After that, continuous sampling of leaves, branches and fruits of the persimmon trees had been carried out for two years. Immediately after the collection, samples were transferred to our laboratory and weighed to obtain fresh weight. Leaf samples were usually separated into two portions; one portion was washed with tap water to remove dust from the surface and the other portion was not treated. For fruit samples, if it is possible, fruit flesh, peal and non-edible part were separated. All the samples were oven-dried at 80 deg. C for three days at least. Each dried sample was chopped into fine pieces, mixed well, and then transferred into plastic vessels separately. Radioactivity concentration was measured by a Ge-detecting system (Seiko EG and G Ortec) using 3000-40000 s counting intervals. By August 14, 2013, about 140 samples were collected from the trees; about 60 samples were leaves (both washed and untreated). Radiocesium concentrations in tree leaves decreased with time, and the effective half-life was about 190 d; the value was similar to those in branches (160 d for new branches, and 250 d for 1-2 y.o. branches) and fruits (250 d for fruit flesh and 230 d for peals). Thus we concluded that the half-life of radiocesium in

    Absrtact:Mining has a range of deleterious effects on the environment, including increasing the concentration of heavy metals in soils. Natural revegetation may contribute to phytoremediation by removing heavy metals. Therefore it’s important to determine which trees are most effective at phytoremediation. The vegetation and the topsoil of the mining area in Dachang Mine of Hechi city, Guangxi Province, China, were investigated, to determine which trees are more suitable for phytoremediation for the heavy metal pollution. The total content of heavy metals (Mn, Zn, Cu, As, Cd, Sn, Sb and Pb) in the leaves of eight tree species and in the topsoil were measured in the three sites in the mining area. The trees were:Pyrus pyrifolia (burm.f.) nakai, Castanea mollissima, Hovenia acerba, Citrus maxima, Ginkgo biloba, Cinnamomum camphora, Diospyros kaki, Eriobotrya japonica. The concentrations of heavy metals in leaves were detected by ICP-MS and ICP-AES, and in soil by ICP-AES. The concentrations of heavy metals were over 5-1200 times background values for soils in the Guangxi Province; with Cd more than 1200 times background values. There were no significant differences in foliar heavy metal contents among the three sampling sites except for Mn;and there were no significant differences among tree species in foliar heavy metal concentrations, either. Concentrations per leaf were converted to values per tree using an equation for tree leaf biomass. H. acerba and C. camphora accumulated more different heavy metals than the others overall. For example a single H. acerba tree can absorb 21.25 g Mn, 3.003g Zn, 0.20 g Cu, 0.28 g As, 0.066 g Cd, 0.014 g Sn, 0.17 g Sb and 1.23 g Pb, while a C. camphora tree can absorb 1.55 g Mn, 0.79g Zn, 0.17 g Cu, 0.12 g As, 0.011 g Cd, 0.017 g Sn, 0.14 g Sb and 0.40 g Pb. The values for the two fruit trees, P. pyrifolia and C. mollissim were also high, for P. pyrifolia can uptake 2.90 g Mn, 3.32 g Zn 0.57 g Cu, 0.11 g As, 0.043 g Cd, 0.014 g

    chloroplast genomes among the hybrids of the 38 fusion combinations,random segregation of chloroplast in Citrus fusion hybrids was further proved,and 1 : 1 segregation ratio were revealed in the fusion combinations of Kinnow tangerine+Jincheng Orange and Bonanza navel orange+Goutou sour orange,respectively.4) Sixty-four DNA samples belonging to 31 kinds of tropical and subtropical fruit crops were ampli-fiedwith the synthesized cpSSR primers,and a set of wide adaptable universal primers were screened. For instance,SPCC1 was rich in polymorphism among intergenera or interspecies,such as persimmon (Dto-spyros kaki ) and dateplum persimmon (Diospyros lotus),banana (Musa spp. ) ,guava (Psidium spp.), papaya (Carica spp. ) and grape (Vitis spp. ).8. Twenty-three genotypes of calli adequately representing the Citrus species and related genera were selected,and corresponding leaves were used as the control to analyze the stability of mitochondrial and chloroplast (plastome) genome. RFLPs,histological section, cpSSR and mtDNA transferring from the cytoplasm to the nuclei were analyzed. The results were as follows:Dlow frequency of mtDNA mutation existed in Citrus calli,while the mtDNA contents increased in individual mitochondria,and no such phenomena were observed in chloroplast genome.2) Analyzed with cpSSR, novel bands were detected among most of the calli. Both Southern hybridization and sequencing proved that the bands were amplified uniquely, suggesting that short sequences insertion occurred frequently in Citrus calli plastid genomes.3) Dot blotting analyses were performed by using nuclear DNA hybridized with mitochondrial probes. Results showed that mitochondrial DNA transfering from cytoplasm into nuclei occurred during long-term subculture.

    Full Text Available Pengamatan filariasis pada penduduk Nualolo-Lekebai, Pulau Flores telah dilakukan pada bulan Februari 1975. Kampung Nualolo-Lekebai berpenduduk 680 jiwa, pekerjaan bertani dan menganut agama Nasrani. Kebiasaan hidup di antara penduduk di daerah ini adalah menyerahkan pelaksanaan pekerjaan berat pada kaum wanita, baik di rumah ataupun di kebun. Dalam perjalanan jauh baik ke kebun atau ke pasar, kaum wanitanya selalu berjalan kaki sedangkan kaum prianya menunggang kuda. Sejumlah 80% dari penduduk kampung ini telah diperiksa terhadap infeksi parasit filaria dan terhadap gejala filariasis. Dari hasil yang ditemukan ternyata penduduk kampung ini menderita infeksi Brugia timori dengan angka derajat infeksi sebesar 7.0% dan angka derajat elephantiasis sebesar 10.3%. Hal yang menarik yang ditemukan dalam pengamatan ini adalah tingginya angka derajat elephantiasis pada kaum wanita dibandingkan dengan pada kaum pria. Fenomena ini mungkin disebabkan oleh kebiasaan hidup kaum wanita di daerah ini sehari-hari yang bekerja lebih berat dan berjalan kaki lebih sering dan lebih jauh dibandingkan kaum prianya.

    2011-09-01

    A potential cause of pododermatitis ("bumblefoot") was investigated in captive-reared juvenile black stilts at the Department of Conservation "Kaki Recovery Program" at Twizel, New Zealand. To address the importance of substrate, the development of clinical signs in individuals was compared among aviaries that contained rubber matting and/or salt footbaths, and controls. No effect of either experimental manipulation of the environment was apparent on pododermatitis development. With the substrate appearing not to be an initiating factor, and a previous study that indicated that the birds' diet fulfills the nutritional requirements for rearing black stilts in captivity, results of this study suggest that insufficient space for exercise may instead be the cause.

    Dichloromethane extracts from different parts of Rhamnus prinoides, Ornithogalum longibracteatum, Gardenia volkensii, Spirostachys africana, Diospyros whyteana, Syzigium cordatum and Prunus africana were investigated for mutagenic and antimutagenic effects in Salmonella/microsome and micronucleus tests. None of the extracts tested in the Ames test were found to induce mutations or to modify the effect of the mutagen 4-nitroquinoline-oxide (4NQO). In the micronucleus test, extracts from twigs/bark of R. prinoides, twigs of D. whyteana, P. africana and S. cordatum significantly lowered the effect of the mutagen mitomycin C (MMC). Extracts from twigs/bark of G. volkensii and S. africana were genotoxic in the micronucleus test, while extracts of O. longibracteatum leaves potentiated the genotoxicity of MMC. This preliminary investigation shows that plant extracts used in traditional medicine may have particular effects with regard to mutagenicity and antimutagenicity indicating careful use in some instances and the need to isolate their active principles for further research.

    1999-01-01

    Full Text Available Grewia occidentalis plants in the study area generally occurred in bush clumps with other shrub species. Grewia occidentalis commonly occurred with Diospyros austro-africana, Rhus longispina and Rhus pollens (nurse shrubs, but seldom with Acacia kar-roo and Lycium cinereum (non-nurse shrubs. Eland browsed G. occidentalis plants at higher levels than other shrub species, but browsing was not evenly spread across all plants. Grewia occidentalis plants associated with nurse shrubs had lower levels of browsing than those growing alone and those growing with non-nurse shrubs, while G. occidentalis plants in the centre of nurse shrubs experienced the lowest levels of browsing. The latter group of plants also produced the most fruit. Eland browsing is consid-ered an important factor determining the distribution of G. occidentalis plants in the study area, while the presence of nurse shrubs is considered essential for the establishment and maintenance of the G. occidentalis population in the study area.

    The concentration of N, P, K, Ca and Na in seedlings of Dalbergia sissoo, Tamarindus indica, Diospyros melanoxylon, Terminalia arjuna and Tectona grandis was evaluated in field plantings in Uttar Pradesh, from the age of 1 to 12 months (April 1978 to March 1979). In all species, concentration of Na in leaves was higher than that of K, Ca and P (highest in D. melanoxylon) and was higher in leaves than in roots and stems. Concentration was found to increase with age of leaves up to 8-9 months (at the time of yellowing), after which N, P and K contents decreased rapidly. N, P and K content of stems and roots showed steady increase with age, but Ca and Na, after showing increases up to 8-10 months showed a slight reduction in the 11th and 12th months. 51 references.

    1999-09-17

    Tobacco use is the leading preventable cause of death in the United States. Bidis are small, brown, hand-rolled cigarettes primarily made in India and other southeast Asian countries consisting of tobacco wrapped in a tendu or temburni leaf (Diospyros melanoxylon ). In the United States, bidis are purchased for $1.50-$4.00 for one package of 20 and are available in different flavors (e.g., cherry, chocolate, and mango). Anecdotal reports indicate that bidi use was first observed during the mid-1990s and seems to be widespread among youth and racial/ethnic minority adolescents. This report summarizes preliminary data collected from a convenience sample of adolescents surveyed during March and early April 1999 in Massachusetts on the prevalence of bidi use among urban youth; these data indicate that of 642 youth surveyed, 40% had smoked bidis at least once during their lifetimes and 16% were current bidi smokers.

    2014-10-01

    Full Text Available The Great Green Wall (GGW has been advocated as a means of reducing desertification in the Sahel through the planting of a broad continuous band of trees from Senegal to Djibouti. Initially proposed in the 1980s, the plan has received renewed impetus in light of the potential of climate change to accelerate desertification, although the implementation has been lacking in all but two of 11 countries in the region. In this paper, we argue that the GGW needs modifying if it is to be effective, obtain the support of local communities and leverage international support. Specifically, we propose a shift from planting trees in the GGW to utilizing shrubs (e.g., Leptospermum scoparium, Boscia senegalensis, Grewia flava, Euclea undulata or Diospyros lycioides, which would have multiple benefits, including having a faster growth rate and proving the basis for silvo-pastoral livelihoods based on bee-keeping and honey production.

    Full Text Available Molecular cytogenetic techniques, such as in situ hybridization methods, are admirable tools to analyze the genomic structure and function, chromosome constituents, recombination patterns, alien gene introgression, genome evolution, aneuploidy, and polyploidy and also genome constitution visualization and chromosome discrimination from different genomes in allopolyploids of various horticultural crops. Using GISH advancement as multicolor detection is a significant approach to analyze the small and numerous chromosomes in fruit species, for example, Diospyros hybrids. This analytical technique has proved to be the most exact and effective way for hybrid status confirmation and helps remarkably to distinguish donor parental genomes in hybrids such as Clivia, Rhododendron, and Lycoris ornamental hybrids. The genome characterization facilitates in hybrid selection having potential desirable characteristics during the early hybridization breeding, as this technique expedites to detect introgressed sequence chromosomes. This review study epitomizes applications and advancements of genomic in situ hybridization (GISH techniques in horticultural plants.

    Challenges of resistance to synthetic antimicrobials have opened new vistas in the search for natural products. This article rigorously reviews plants and other natural products used in oral health: Punica granatum L. (pomegranate), Matricaria recutita L. (chamomile), Camellia sinensis (L.) Kuntze (green tea), chewing sticks made from Diospyros mespiliformis Hochst. ex A.D.C., Diospyros lycioides Desf., and Salvadora persica L. (miswak), honey and propolis from the manuka tree (Leptospermum scoparium J.R. Forst. & G. Forst.), rhein from Rheum rhabarbarum L. (rhubarb), dried fruits of Vitis vinifera L. (raisins), essential oils, probiotics and mushrooms. Further, the review highlights plants from Africa, Asia, Brazil, Mexico, Europe, and the Middle East. Some of the plants' antimicrobial properties and chemical principles have been elucidated. While the use of natural products for oral health is prominent in resource-poor settings, antimicrobial testing is mainly conducted in the following countries (in decreasing order of magnitude): India, South Africa, Brazil, Japan, France, Egypt, Iran, Mexico, Kenya, Switzerland, Nigeria, Australia, Uganda, and the United Kingdom. While the review exposes a dire gap for more studies on clinical efficacy and toxicity, the following emerging trend was noted: basic research on plants for oral health is mainly done in Brazil, Europe and Australia. Brazil, China, India and New Zealand generally conduct value addition of natural products for fortification of toothpastes. African countries focus on bioprospecting and primary production of raw plants and other natural products with antimicrobial efficacies. The Middle East and Egypt predominantly research on plants used as chewing sticks. More research and funding are needed in the field of natural products for oral health, especially in Africa where oral diseases are fuelled by human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS).

    Full Text Available Study on the socio-cultural aspects in relation to filariasis transmission dynamics was carried out in the transmigration area of Kumpeh, Iambi. In this study a number of 266 respondents originated from Java were interviewed. Beside interview by using questionnaires, focus group discussions and observation were also implemented. From this study it was known that the word "filariasis" seemed to be unpopular among the transmigrants. They used to called the disease untut or penyakit kaki gajah. A great number of the respondents stated that the disease is transmitted through mosquito bites, but they did not know the mode of the transmission. A small number of the respondents were of the opinion that the disease was hereditary and this knowledge was adopted from the local inhabitants. The attitude of the respondents towards filariasis control measures was positive, and it was shown among others, by their willingness to be bled for filariasis examination. Their behaviour in its connection with filariasis transmission was not supportive towards filariasis control e.g. they used to stay in the ladang, and chat outdoor during the night without protection against mosquito bites. From this study it was also known that they exposed themselves to the mosquito bites mainly in the ladang when they take guard of their crops from pests damages. Their low education affected their perception towards filariasis and will hamper health education on filariasis control.

    Full Text Available Filariasis atau kaki gajah adalah penyakit menular yang disebabkan karena infeksi cacing filaria yang hidup disaluran dan kelenjar getah bening (limfe serta menyebabkan gejala akut, kronis. Filariasis mulai dikenal di Indonesia tahun 1889 sejak Haga dan Van Eecke menemukan kasus pembesaran scrotum di Jakarta. Penyakit tersebut dapat menular kepada orang lain dengan perantara gigitan nyamuk. Seluruh wilayah Indonesia berpotensi untuk terjangkitnya penyakit tersebut, hal ini mengingat cacing sebagai penyebabnya dan nyamuk penularnya tersebar luas. Keadaan ini didukung oleh kerusakan lingkungan, seperti banjir, penebangan hutan dan lainnya yang memperluas tempat berkembangbiaknya nyamuk. Meskipun filariasis tidak mematikan secara langsung, dengan adanya demam dan bisul-bisul (abses yang hilang timbul, dan gejala menahun berupa pembesaran/elefantiasis yang merupakan cacat menetap akan sangat mengganggu. Secara ekonomis keadaan tersebut sangat merugikan, karena mengurangi produktivitas masyarakat, serta diperlukan biaya pengobatan dan perawatan yang tidak mudah dan tidak murah.Di Indonesia filariasis limfatik di sebabkan oleh tiga spesies cacing filaria yaitu Brugia malayi,B.timori dan Wuchereria bancrofti, yang terbagi lagi menjadi 6 tipe secara epidemiologi.Tiap parasit mempunyai siklus hidup yang kompleks dan infeksi pada manusia tidak akan berhasil kecuali jika terjadi pemaparan larva infektif untuk waktu yang lama. Setelah terjadi pemaparan, dibutuhkan waktu bertahun-tahun sebelum timbulnya perubahan patologis yang nyata pada manusia. Periodisitas dalam sirkulasi setiap mikrofilaria akan berbeda, tergantung dari spesiesnya.

    Full Text Available My first experiences of Japan were so early in life that they are hazy in my memory. My neighbours in São Paulo City, a sprawling megalopolis in Brazil, were Japanese migrants. I was seven or eight when I first saw their festivals and performance presentations from my parents’ bedroom window. I remember my awe at their colourful costumes, masks and music. On a daily basis I remember the pungent smell of the soy sauce they produced in a factory in their backyard. We also shopped at a small neighbourhood supermarket called Shinohara. We bought paper and sticks for our kites from a general store owned by another Japanese migrant. We would tell our mother that we were going to ride our bikes to the ‘Japonesa’ to get kite material. At home, caqui (Japanese kaki was my favourite fruit, but we also had all sorts of vegetables the Japanese migrants brought from Japan. We even called Japanese pumpkin by its Japanese name – kabocha.

    Full Text Available Repeated slash and burn cultivation creates wasteland with thorny shrubs, which then takes a long time to become secondary forests through serial stages of succession. Assisted natural regeneration through silvicultural management is a useful restoration method to accelerate succession. This survey evaluates the effectiveness of a simple silvicultural method for the rehabilitation of degraded lands to productive forest, thereby increasing floristic wealth. Field-based comparative analyses of floristic composition were carried out at a silviculturally managed forest (Popham Arboretum and a primary forest (Kaludiyapokuna Forest Reserve which is located in Dambulla in Sri Lanka. Floristic analysis was used to examine the effectiveness of silvicultural techniques for successful restoration of degraded forest in the dry zone. Nine 20 m × 20 m plots in each forest were enumerated and the vegetation ≥ 10 cm girth at breast height was quantitatively analyzed. Cluster analysis resulted in five distinguishable clusters (two from Popham Arboretum and three from Kaludiyapokuna Forest Reserve. Similarity indices were generated to compare the plots within and between sites. Floristic similarity was higher in forest reserve plots compared to arboretum plots. A total of 72 plant species belonging to 60 genera and 26 families were recorded from the study sites. Of the recorded species, Grewia damine and Syzygium cumini (Importance Value Index, IVI = 24 and 23 respectively were the ecologically co-dominant taxa at the Popham Arboretum. In contrast, Mischodon zeylanicus (IVI = 31, Schleichera oleosa (IVI = 25 and Diospyros ebenum (IVI = 21 were the abundant taxa in the forest reserve.

    Full Text Available The major plant communities of the Karoo National Park are described using the methods of the Zurich-Montpellier school of phytosociology, to assist with the formulation of a management strategy for the park. The vegetation physiognomy consists of Montane Karoo grassy shrublands. Karoo grassy dwarf shrublands. Karoo succulent dwarf shrublands and riparian thicket. Steep elevation and precipitation gradients within the study area have a direct impact on gradients in the vegetation. High elevation (1 800 m, and relatively high rainfall (406 mm montane grasslands occupy communities dominated by grasses (Merxmuellera disticha, Themeda triandra and woody species (Diospyros austro-africana, Elytropappus rhinocerotis, Euryops annae, Passerina montana. The increasing aridity away from the escarpment edge in a northerly direction is steep, and Montane Karoo dwarf shrublands replace these mesic communities. Species such as Eriocephalus ericoides, Rosenia oppositifolia and Pteronia tricephala dominate. At lower elevation (800 m the precipitation is very low (175 mm and uncertain (coefficient of variation of 78 . The substrata influence the vegetation, with the sandy substrata of the drainage lines supporting more woody taxa (Acacia karroo, Lycium cinereum and grasses (Hyparrhenia hirta, Stipagrostis namaquensis, Cenchrus ciliaris. Moving away from the mesic environment of the riparian zone, rapid desiccation occurs and the most xeric communities are encountered, dominated by Stipagrostis obtusa, S. ciliata and Pent-da incana. This document provides descriptions of the general communities and their associated landscape, lithology and soils.

    Despite the common occurrence of ringtails (Bassariscus astutus) few studies have been conducted to assess population characteristics. The objectives of this study were to determine (1) habitat selection, (2) home range, (3) denning characteristics, and (4) food habits of ringtails in the Trans Pecos region of west Texas. Seventeen ringtails were captured between November 1999 and January 2001 using Havahart live box traps. Second- and third-order habitat selection was determined for a ringtail population using range sites, slope, elevation, and vegetation communities. Diets were determined from volumetric scat analysis. The mean summer and winter range sizes (100% Minimum Convex Polygon [MCP]) for ringtails (n = 5) were 0.28 ?? 0.163 km2 and 0.63 ?? 0.219 km2, respectively. Overlap between ringtail ranges averaged 33.3%. Ringtails preferred catclaw (Mimosa biuncifera), persimmon (Diospyros texana), oak (Quercus sp.) bottom and catclaw/goldeneye (Viguiera stenoloba), sideoats (Bouteloua curtipendula) slope communities. Rock dens were used exclusively by ringtails, with 80.6% of dens found on slopes between 30-60%. Plant (seeds and miscellaneous vegetation) and animal material were found in 74.6 and 86.6% of scats, respectively. Findings suggest that ringtails in Trans Pecos, Texas, are an important component of the ecosystem and that management practices should conserve canyon habitats and adjacent slopes for ringtails.

    There is increasing evidence that restoration ecologists should be most concerned with restoring species interactions rather than species diversity per se [1]. Rewilding with taxon substitutes, the intentional introduction of exotic species to replace the ecosystem functions of recently extinct species, is one way to reverse ecosystem dysfunction following the loss of species interactions [2]. This is highly controversial [3], in part because of a lack of rigorous scientific studies [4]. Here we present the first empirical evidence of an in situ rewilding project undertaken as a hypothesis-driven ecosystem management option. On Ile aux Aigrettes, a 25-hectare island off Mauritius, the critically endangered large-fruited endemic ebony, Diospyros egrettarum (Ebenaceae), was seed-dispersal limited after the extinction of all native large-bodied frugivores, including giant tortoises. We introduced exotic Aldabra giant tortoises, Aldabrachelys gigantea, to disperse the ebony seeds. Not only did the tortoises ingest the large fruits and disperse substantial numbers of ebony seeds, but tortoise gut passage also improved seed germination, leading to the widespread, successful establishment of new ebony seedlings. Our results demonstrate that the introduction of these exotic frugivores is aiding the recovery of ebonies. We argue for more reversible rewilding experiments to investigate whether extinct species interactions can be restored.

    Full Text Available Medicinal plants have long been used as a source of therapeutic agents. They are thought to be important anti-aging ingredients in prophylactic medicines. The aim of this study was to screen extracts from Taiwanese plant materials for phenolic contents and measure the corresponding matrix metalloproteinase-9 (MMP-9 activity. We extracted biological ingredients from eight plants native to Taiwan (Alnus formosana, Diospyros discolor, Eriobotrya deflex, Machilus japonica, Pyrrosia polydactylis, Pyrus taiwanensis, Vitis adstricta, Vitis thunbergii. Total phenolic content was measured using the Folin-Ciocalteu method. MMP-9 activities were measured by gelatin zymography. The extracted yields of plants ranged from 3.7 % to 16.9 %. The total phenolic contents ranged from 25.4 to 36.8 mg GAE/g dry material. All of these extracts (except Vitis adstricta Hance were shown to inhibit MMP-9 activity of WS-1 cell after ultraviolet B irradiation. These findings suggest that total phenolic content may influence MMP-9 activity and that some of the plants with higher phenolic content exhibited various biological activities that could serve as potent inhibitors of the ageing process in the skin. This property might be useful in the production of cosmetics.

    During 2008 and 2009, the efficacy of the combination of two Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), control techniques, sterile insect technique (SIT) and a chemosterilant bait station system (Adress), was tested in three crops: citrus (Citrus spp.), stone fruit (Prunus spp.), and persimmon (Diospyros spp.). Two thousand sterile males were released per ha each week in the whole trial area (50,000 ha, SIT area). For 3,600 ha, within the whole trial area, 24 Adress traps per ha were hung (SIT + Adress area). Ten SIT + Adress plots and 10 SIT plots in each of three different fruit crops were arranged to assess Mediterranean fruit fly population densities and fruit damage throughout the trial period. To evaluate the efficacy of each treatment, the male and female populations were each monitored from August 2008 to November 2009, and injured fruit was assessed before harvest. Results showed a significant reduction in the C. capitata population in plots treated with both techniques versus plots treated only with the SIT. Likewise, a corresponding reduction in the percentage of injured fruit was observed. These data indicate the compatibility of these techniques and suggest the possibility of using Adress coupled with SIT to reduce C. capitata populations in locations with high population densities, where SIT alone is not sufficiently effective to suppress fruit fly populations to below damaging levels.

    Full Text Available Characterisations of the Sloth bear (Melursus ursinus diet during three distinguished seasons (monsoon, winter and summer in the semi-arid region of western India was under study. Diet was estimated using scat analysis, based on the calculation of Index of Relative Importance (IRI in order to determine the contribution of different food items in the Sloth bear diet. Sloth bears were observed to feed on a wide variety of prey items. They are specialized on insect prey, particularly termites or ants, and are considered as myrmecophagous. The myrmecophagousis character was confirmed by the highest score of insect part (IRI = 21.37 from the samples (n = 566, which was followed by Diospyros melanoxylon (IRI Score 13.51, Ficus spp. (IRI score 12.69 and Cassia fistula (IRI Score 10.13. Sloth bear dietary proportions varied among the three seasons under the study interval. Data suggested that the Sloth bear is essentially behaving as an omnivore, having similar diet (in terms of high incidence of wild fruits and insects with the bears inhabiting semi-arid regions. The opportunistic and generalist strategy of selecting diet ingredients has probably helped the species to survive in semi-arid habitat across the North Gujarat.

Melalui pendekatan etnomusikologi, tulisan ini menelaah peranan musik internal dan eksternal dalam kesenian Randai. Kesenian ini menggunakan medium seni ganda atau kolektif karena didukung oleh beberapa cabang seni antara lain tari, musik, teater, sastra, dan rupa. Hasil penelitian menunjukkan bahwa musik iringan dalam Randai terbagi menjadi dua, yaitu musik internal dan musik eksternal. Musik internal adalah musik atau bunyi-bunyian yang berasal dari anggota tubuh manusia (penari, misalnya tepukan tangan, petik jari, tepuk dada, siulan, hentakan kaki ke tanah dan sebagainya, sedangkan musik eksternal adalah bunyi-bunyian atau suara yang berasal dari alat musik atau instrumen seperti talempong, gandang, saluang, dan rabab.   The Role of Internal and External Music in the Arts of Randai. The musical life in Minangkabau society is inseparable from its roles and functions which attach to the arts of Randai. Through the ethnomusicology approach, this paper examines the role of internal and external music in the art of Randai. Considering its sustainability and amendment, the musicality is the identity of Minangkabau society so that the sustainability of the music can be run in accordance with the dynamics of society today. Among the types of arts in Minangkabau, Randai is an art form that uses multiple or collective art medium for it is supported by several branches of the arts, including dance, music, theater arts, literary arts, and fine arts. The results of this study is more focused on the art of music. Musical accompaniment in Randai is divided into two, namely internal and external music. The internal music is the music or the sounds that come from the human body (a dancer, for example, clapping, finger picking, patting the chest, whistling, stomping on the ground, and so on, while the external music is the sounds

The immediate and most critical urban environment problems facing several big cities, such as Jakarta and Surabaya, what are referred to as the "brown" problems, among them: lack of safe water, pollution from vehicles and industrial facilities, and congestion. To cope with these urban environmental problems, New Urbanism through the Traditional Neighborhood Development (TND believes that it will cure the problems by pedestrian oriented planning, encouraging people to drive less, mixed land uses, higher density, then traffice congestion is reduced,and mitigate air pollution. Moreover, the other physical and social characters are mixed housing types, front porches, more park that will encourage more interaction, then restore a sense of community. Based on this concept, this paper discusses the physical and social characters of real estates in Jakarta and Surabaya. The results show that real estate developments in these suburban areas is one of the causes of urban environment problems. Abstract in Bahasa Indonesia : Cepatnya urbanisasi akan menyebabkan lingkungan perkotaan yang kritis. Masalah lingkungan kritis yang dihadapi oleh kota-kota besar seperti Jakarta dan Surabaya adalah apa yang disebut dengan masalah "warna coklat" yaitu kurangnya air yang sehat, polusi udara yang berasal dari kendaraan bermotor dan industri, serta kemacetan lalu lintas. Untuk menyelesaikan masalah lingkungan ini, gerakan New Urbanism melalui konsep Traditional Neighborhood Development (TND percaya bahwa masalah lingkungan ini dapat diatasi dengan perencanaan permukiman yang berorientasi pada pejalan kaki, multi fungsi, kepadatan tinggi, sehingga mengurangi kendaraan bermotor dan berakibat pada berkurangnya kemacetan lalu lintas dan polusi udara.

    Full Text Available Em paisagens fragmentadas, a colonização por novas espécies em reflorestamentos e capoeiras é dificultada pelas grandes distâncias das fontes de propágulos e a alta degradação do solo. Neste contexto, o enriquecimento artificial de reflorestamentos com espécies nativas de níveis sucessionais mais avançados torna-se imprescindível para garantir a sustentabilidade do ecossistema. Métodos como a transferência de serapilheira e solo de florestas maduras e a semeadura direta podem ser alternativas. Amostras de serapilheira e solo foram distribuídas em duas áreas de reflorestamento e uma área-controle, e nove espécies nativas não-pioneiras foram semeadas diretamente nas mesmas áreas e em dois controles. Da serapilheira, germinaram 14 espécies no controle: sete arbóreas, três herbáceas, duas lianescentes e duas arbustivas. As árvores são na maioria pioneiras e, portanto, de interesse limitado para o enriquecimento. Entretanto, as espécies não-arbóreas, importantes na diversidade de ecossistemas florestais, representaram metade dos indivíduos catalogados. Na semeadura direta, a espécie mais interessante foi Diospyros brasiliensis, com taxas de germinação de 50%. Achatocarpus pubescens e Cordia ecalyculata apresentaram resultados expressivos, apesar de heterogêneos. Os resultados mostram que são necessários estudos sobre a época de coleta da serapilheira e a influência do clima na germinação das sementes e emergência de plântulas.In fragmented landscapes, large distances from seed sources and strong soil degradation raises difficulties for colonization of new species in reforested areas and in early secondary forests. In this context, the artificial enrichment of reforestation areas with advanced successional level species is vital for the ecosystem sustainability.

    Full Text Available In order to describe community structure and richness in oak and walnut forests occurring along the San Rodrigo, San Diego, Escondido and Arroyo de las Vacas rivers on the Northeastern Coastal Plain (NE Coahuila, Mexico, we established 30 1 000-m² circular plots, where we measured diameter at breast height (DBH and tree heights. Tree regeneration and herb and shrub stratum were assessed in 5 2-m² quadrats per site. A total of 48 species distributed in 29 families were recorded. Families with the largest richness were Poaceae, Asteraceae, and Malvaceae. For the oak forest, tree stratum density and basal area values were 386 stems/ha and 24.36 m²/ha, respectively, whereas for the walnut forest the corresponding values were 302 stems/ha and 21.26 m²/ha. The species with the highest relative importance values were Quercus fusiformis (59.48% and Carya illinoinensis (57.58%. Total tree richness was 14 species, the most common ones being Celtis reticulata and Diospyros texana, followed closely by C. illinoinensis and Q. fusiformis. Anthropogenic impact appears to result in a poor regeneration reflected as a low sapling density, as well as in the reduction and fragmentation of these communities; in turn, this process has led to intrusions of species typical of the xerophytic Tamaulipan Thorn Scrub. Further studies are needed on the regeneration of the dominant species of these forests in order to describe their dynamics and to promote their preservation.Con la finalidad de conocer la estructura y la composición florística de los bosques de encino y nogal situados a lo largo de los ríos San Rodrigo, San Diego, Escondido y Arroyo de las Vacas en la planicie costera nororiental (NE de Coahuila, México, se establecieron 30 parcelas circulares de 1 000 m² en las que se midió el DAP y la altura de las especies arbóreas; además, se evaluó la regeneración de las especies arbóreas y el estrato herbáceo y arbustivo en 5 cuadros de 2 m² por sitio

    Full Text Available Solid wastes from agro-industrial operations can be recycled as non-conventional adsorbents if they are inert and harmless and reduce the cost of wastewater treatment. Tendu leaf Diospyros melanoxylon is the second largest forest product in India after timber and is exclusively used in making local cigarette called Bidi. Waste leaf cutting remaining after making cigarette was used in present study as a biosorbent for the removal of Congo red dye from aqueous solution. It was treated with hydrogen peroxide to obtain biosorbent with increased adsorption capacity. Batch type experiments were conducted to study the influence of different parameters such as pH, initial dye concentration and dosage of adsorbent on biosorption evaluated. The adsorption occured very fast initially and attains equilibrium within 60 min at pH= 6.2 and the equilibrium attained faster after hydrogen peroxide modification. Kinetic studies showed that the biosorption of Congo red on tendu waste followed pseudo-second-order rate equation. The data fitted well to Langmuir and Freundlich isotherm models. Comparison was done on the extent of biosorption between untreated and treated forms of the tendu waste. The maximum adsorption capacity for untreated tendu waste was found to be 46.95 mg/g, which was enhanced by 2.8 times after hydrogen peroxide treatment and was found to be 134.4 mg/g. The adsorption process was in conformity with Freundlich and Langmuir isotherms for Congo red adsorption from aqueous solution. The study demonstrated use of milder chemical treatment of tendu waste to obtain a biosorbent with enhanced dye removal capacity.

    Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking water and an increased risk of spreading the water-borne disease. Not surprisingly, plants found in the near surroundings have been taken into use by the local community as medicine to treat diarrhoeal symptoms. These plants are cheaper and more easily available than conventional medicine. Our question is: What is the level of documentation supporting the use of these plants against diarrhoea and is their consumption safe? Do any of these plants have potential for further exploration? In this review, we have choosen seven plant species that are used in the treatment of diarrhoea; Diospyros peregrina, Heritiera littoralis, Ixora coccinea, Pongamia pinnata, Rhizophora mucronata, Xylocarpus granatum, and Xylocarpus moluccensis. Appearance and geographical distribution, traditional uses, chemical composition, and biological studies related to antidiarrhoeal activity will be presented. This review reveals that there is limited scientific evidence supporting the traditional use of these plants. Most promising are the barks from D. peregrina, X. granatum and X. moluccensis which contain tannins and have shown promising results in antidiarrhoeal mice models. The leaves of P. pinnata also show potential. We suggest these plants should be exploited further as possible traditional herbal remedies against diarrhoea including studies on efficacy, optimal dosage and safety.

    Full Text Available Abstract Background Six herbs in the Plant Genetics Conservation Project that have been used as complementary medicines were chosen on the basis of their medicinal value, namely Terminalia mucronata, Diospyros winitii, Bridelia insulana, Artabotrys harmandii, Terminallia triptera, and Croton oblongifolius. This study aims to evaluate the potential anticancer activity of 50% ethanol-water extracts of these six herbs. Methods Fifty percent ethanol-water crude extracts of the six herbs were prepared. The cytotoxicity of the herbal extracts relative to that of melphalan was evaluated using a hepatoma cell line (HepG2, and examined by neutral red assays and apoptosis induction by gel electrophoresis and flow cytometry after 24 h. Results A significant difference was found between the cytotoxicity of the 50% ethanol-water crude extracts and melphalan (P = 0.000. The 50% ethanol-water crude extracts of all six herbs exhibited cytotoxicity against HepG2 cells, with IC50 values ranging from 100 to 500 μg/mL. The extract of T. triptera showed the highest cytotoxicity with an IC50 of 148.7 ± 12.3 μg/mL, while melphalan had an IC50 of 39.79 ± 7.62 μg/mL. The 50% ethanol-water crude extracts of D. winitii and T. triptera, but not A. harmandii, produced a DNA ladder. The 50% ethanol-water crude extracts of D. winitii, T. triptera, and A. harmandii induced apoptosis detected by flow cytometry. Conclusion The 50% ethanol-water crude extracts of D. winitii, T. triptera, and A. harmandii showed anticancer activity in vitro.

    Objective: To characterize thermal property of natural gums obtained from the seeds of Diospyros melonoxylon(D. melonoxylon) Roxb, Buchanania lanzan (B. lanzan) spreng and Manilkara zapota (M. zapota) (Linn.) P. Royen syn. Methods: Natural gums were thermally characterized using differential scanning calorimetry (DSC), differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA) under nitrogen atmosphere. Major thermal transitions as well as activation energies of the major decomposition stages were determined. Elemental analysis was performed in order to determine the composition of carbon, hydrogen, nitrogen and sulfur. Results: DSC traces indicated a major intense exothermic transition (around 200℃) followed by weaker exotherm(s). Thermogravimetric analysis showed two phase of weight loss. The first phase has minor weight loss in samples is attributed to the loss of adsorbed and structural water of biopolymers or due to desorption of moisture as hydrogen bound water to the saccharide structure. The second weight loss event may be attributed to the polysaccharide decomposition. The initial decomposition temperature (IDT) was calculated from thermograms obtained of TGA, seed Polysaccharide of D. melonoxylon (IDT 221.21℃), B. lanzan (IPDT 170.4℃) and M. zapota (IPDT 178.6℃) were obtained. According to the integral procedural decomposition temperature (IPDT) values calculated based on the TGA thermograms; D. melonoxylon (IPDT 563.3℃), B. lanzan (IPDT 598.1℃) and M. zapota (IPDT 600.6℃) were obtained respectively. The elemental analysis study shows that the isolated natural Polysaccharides consist of certain percentage of carbon, nitrogen, sulphur and hydrogen in all the gums. Conclusions: The results of the present investigation reveal that the natural gums are thermally stable and these gums can be used as release modifiers in various dosage forms.

    We studied moist deciduous forests of Chhattisgarh, India (1) to assess the effect of four levels of historic wildland fire frequency (high, medium, low, and no-fire) on regeneration of seedlings in fire affected areas during pre and post-fire seasons, (2) to evaluate vegetation struc-ture and diversity by layer in the four fire frequency zones, (3) to evalu-ate the impact of fire frequency on the structure of economically impor-tant tree species of the region, and (4) to quantify fuel loads by fire fre-quency level. We classified fire-affected areas into high, medium, low, and no-fire frequency classes based on government records. Tree species were unevenly distributed across fire frequency categories. Shrub density was maximum in zones of high fire frequency and minimum in low-frequency and no-fire zones. Lower tree density after fires indicated that regeneration of seedlings was reduced by fire. The population structure in the high-frequency zone was comprised of seedlings of size class (A) and saplings of size class (B), represented by Diospyros melanoxylon, Dalbergia sissoo, Shorea robusta and Tectona grandis. Younger and older trees were more abundant for Tectona grandis and Dalbargia sis-soo after fire, whereas intermediate-aged trees were more abundant pre-fire, indicating that the latter age-class was thinned by the catastrophic effect of fire. The major contributing components of fuel load included duff litter and small woody branches and twigs on the forest floor. Total fuel load on the forest floor ranged from 2.2 to 3.38 Mg/ha. The net change in fuel load was positive in high- and medium-frequency fire zones and negative under low- and no-fire zones. Repeated fires, how-ever, slowly reduced stand stability. An ecological approach is needed for fire management to restore the no-fire spatial and temporal structure of moist deciduous forests, their species composition and fuel loads. The management approach should incorporate participatory forest manage

    Full Text Available Este estudo, realizado na Mata de Galeria do córrego Bacaba (14º41'S e 52º20'W, em Nova Xavantina, MT, avaliou as mudanças na estrutura da vegetação no período de 1999 a 2006. Em 1999, foram demarcadas 141 parcelas permanentes em três porções da mata (alto, meio e baixo, em um gradiente topográfico, e medidos os indivíduos com CAP ≥ 15 cm. No inventário de 2006, os indivíduos foram remedidos e os recrutas, computados. Em 2006, amostraram-se 135 espécies, 113 gêneros e 49 famílias. A posição hierárquica das espécies apresentou mudanças expressivas em relação a 1999. Na porção do alto, as espécies com maior valor de importância (VI foram: Astrocaryum vulgare, Diospyros guianensis e Calophyllum brasiliense. Essa porção pode ter sido a mais afetada pelo fogo que atingiu a área em 2001, visto que uma espécie típica de ambientes antropizados passou a ocupar a primeira posição de VI. No meio, as espécies mais importantes em 2006 foram: Aspidosperma subincanum, Tetragastris altissima e Hymenaea courbaril. No baixo, apenas Mauritia flexuosa manteve a mesma posição do inventário anterior, e a maior alteração hierárquica foi apresentada pelas espécies pioneiras, sugerindo um fechamento da vegetação. Entre as 10 espécies de maior VI em 2006, nenhuma foi comum às três porções da mata. Características estruturais distintas da vegetação entre áreas geograficamente tão próximas podem estar relacionadas à heterogeneidade do ambiente. As mudanças no VI registradas nas espécies das três porções de mata reforçam a ideia de que esta apresenta elevada dinâmica.

    SummaryStemflow hydro-ecological importance was measured in trees and assessed in Mexico's northeast forest stands by answering three basic questions: (a) what are the intra and inter-specific stemflow variations; (b) is the stemflow coefficient constant from tree level to stand scales? and (c) what is the stemflow area and wetted soil volume in individual trees and the stemflow volume discharged at the stand scale in two plant communities of northeastern Mexico? Gross rainfall and stemflow flux measurements were conducted on 78 trees of semi-arid, sub-tropical (31 Diospyros texana; 14 Acacia rigidula; four Bumelia celastrina; five Condalia hookeri; three Cordia bioissieri; three Pithecellobium pallens) and temperate forest communities (six Pinus pseudostrobus Lindl. and 12 Quercus spp.). Stemflow was extrapolated from individual trees to the stand scale using 98 inventory plots (1600 m 2 ha -1 each) placed in oak-pine forests and 37 quadrats (5 m × 5 m each) distributed across the Tamaulipan thornscrub forest range. Stemflow infiltration flux and infiltration area measurements assessed the wetted soil volume. Daily measurements were conducted from May of 1997 to November of 1998. Results showed that stemflow coefficients varied between plant communities since they averaged (confidence intervals, α = 0.05) 2.49% (0.57), 0.30% (0.09), and 0.77% (0.27) of the bulk precipitation for Tamaulipan thornscrub, pine, and oak forests, respectively. Intra-specific stemflow variations could not be identified in Tamaulipan although in temperate tree species. Basal diameter explained intra-specific stemflow variation in both plant communities. Stemflow increased threefold since it accounted for by 6.38% and 2.19% of the total bulk rainfall for Tamaulipan thornscrub quadrats and temperate oak-pine inventory plots, respectively. Small shrubs growing underneath large trees, in combination with the presence of small-diameter trees that recorded the largest stemflow coefficients

    Full Text Available Flesh softening, skin browning and rotting are chief problems during cold storage (CS of 'Fuyu' Persimmon. We studied the effects of boron (B and calcium (Ca sprayed on the trees during three consecutive years, on the development of skin cracks, grooves and browning in persimmon fruit under CS in Farroupilha, RS, Brazil (29°31' south, 51°21' west, about 750 m altitude. A homogeneous orchard area of 0.5 ha was delimitated and three sets of five plants for each treatment were randomly selected. The persimmon trees were sprayed at a 20 day interval, from 15th January until harvest, for three consecutive years, with: T1 water; T2 calcium nitrate at 0.5% (m/v; T3 calcium chloride at 0.5% (m/v; and T4 boron at 0.3% (m/v. The fruit were harvest with orange-reddish colour; 18-20°Brix, pulp firmness of 45 to 60N, and kept under CS at 0±1°C for 45 days. The fruits were evaluated immediately before CS, after six hours at 23±2°C after removal from CS, and after four days at 23±2°C after removal from CS. Equally boron and calcium sprayed on the trees prevented skin cracks, skin grooves and skin browning. Besides, when boron was sprayed on the trees, the mentioned effects were additive in the following year.As principais alterações indesejáveis observadas no período pós-colheita de caquis em armazenamento refrigerado (AR são a perda de firmeza de polpa, e a ocorrência de escurecimento epidérmico e de podridões.

Artifacts such as polished black pottery,white pottery,jade and large oracle bones were found. The location of Yangdi or Juntai where Yu and Qi lived was in Yuzhou according to the literature.Charcoals were collected from pits, houses, ditches and cultural layer during the excavation of Wadian Site both in 2007 and 2008. One thousand and thirty charcoals were identified and one thousand and nine charcoals belonged to 26 genera,including Quercus sp. (3 genus) ,Zizyphus sp., Zelkova sp., Ulmus sp., Malus sp., Armeniaca sp., Fraxinus sp., Diospyros sp., Acer sp., Castanea sp., Cudrania sp., Rhus sp., Populus sp., Cyclobalanopsis sp., Platycladus orientalis, Bambusoideae and 8 tree species and 23 charcoals were skulls of spine date and cupules.According to the statistic results,the oak was dominant,the percentage was 79.5%; the second was bamboo, accounting for 3. 4% ; the third was glauca, accounting for 3. 1% ; the fourth was the date, accounting for 2. 6% ; the fifth is unknown species, accounting for 2. 2% ; the sixth was beech, accounting for 1. 3% ; the seventh was unknown genus, accounting for 1. 1 % ; and the rest was a small proportion of other species, of which only one kind of conifer was Chinese arborvitae, accounting for 0.2%. Oak deciduous forest, evergreen and deciduous broad-leaved mixed forest, bamboo, other trees and fruit trees were distributed around the Wadian Site.Oak charcoals scattered in the cultural layer were dominant, the percentage was 68. 2%; the second was glauca, accounting for 6. 9

    here, and working wonderfully. Tortoises pull the weeds, apply the fertilizer, and germinate the seeds. Regarding the latter, recently published experiments2 show that passing through the slow digestive system of a giant tortoise is just what some of these hard - to - germinate seeds of rare native plants have been waiting for. The authors show conclusively that the highly endangered, large - seeded native ebony tree (Diospyros egrettarum is germinating and thriving on the remarkable 25-hectare Ile aux Aigrettes Reserve, a small island off Mahebourg, Mauritius, thanks to the Aldabra tortoises reintroduced there by the Mauritian Wildlife Foundation. At the Leguat Reserve on Rodrigues, guides lead thousands of visitors per year through huge spectacular limestone caves that have yielded the fossils of giant tortoises, Solitaires, and the other extinct biota of Rodrigues. Their tour, and the excellent museum on the Reserve, make that wonderful connection between the fossils of a remarkable extinct fauna, and the rare plants and surviving fauna of large handsome fruit bats, rare land snails, nesting White - tailed Tropicbirds, and the surviving cousins of the native giant tortoises now roaming the canyons and plateaus of the Reserve. What am I doing here? To begin with, my wife Lida Pigott Burney and I have in recent years started our own similar rewilding project on the island of Kaua`i, in the Hawaiian Islands. We likewise have a cave system, full of fossils of the extinct animals, as a centerpiece for restorations on worn - out farmland that feature thousands of native plants, some quite rare. Our big fossil herbivores, giant flightless ducks and geese, are all extinct, and alas, tortoises never reached Hawaii. So we laboriously pull the weeds, tons of them, with the help of the school children of Kaua`i and hundreds of volunteers. The current question I and my colleagues are asking is, could giant tortoises give us a hand, serving as ecological surrogates for the lost
