    Full Text Available Campsis radicans is an attractive climber with typical ornitogamous flowers, native to North America. In natural conditions this out-crossed plant is pollinated mostly by hummingbirds. In Poland, where C. radicans is cultivated as ornamental, it rarely sets seeds. The questions addressed in the present study were: (1 What animals pollinate its flowers in Poland?, and (2 What is the reason for infrequent fruit set? Field studies conducted in five localities in Poland showed that the principal pollinator is Apis mellifera, and the lack of seeds is usually caused by pollinator limitation or absence of genetically different pollen donor plants.

    The precise factors affecting stigma behavior in Campsis radicans (L.) Seem. ex Bureau. remain unclear up to now. In this study mechanical touch, self- and cross-pollination, and pollination with variable amounts of pollen grains separately contacting with stigmas have been conducted to determine the exact factor affecting the stigma behavior. Results show that mechanical touch alone cannot make the stigmas close permanently. It is the adequate pollen (>350) deposition that causes the stigma permanent closure, which is in accordance with previous reports that sufficient pollen grains are necessary for fruit development. In addition, the stigma behavior does not display differences when pollinated with cross- or self-pollen separately; both self and cross pollen grains can germinate and grow successfully. Our results cannot demonstrate that the stigma behavior in C. radicans is an outcrossing mechanism, but strongly indicate it acts as a mechanism to facilitate pollination, and then enhance the reproductive success.

    Full Text Available In the present review, the main objective was to report the incidence and causes of herbal medicines induced anticholinergic poisoning in Hong Kong during 1989–2012 and to emphasize the importance of pharmacovigilance, investigations and preventive measures. Relevant papers, official figures and unpublished data were obtained from Medline search, the Department of Health and the Drug and Poisons Information Bureau. In the New Territories East (where ~20% of the Hong Kong population lived, the incidence of herbal medicines induced anticholinergic poisoning during 1989–1993 was 0.09 per 100,000 population. There were no confirmed cases during 1994–1996. In the whole of Hong Kong, the incidence during 2000–June 2005 was 0.03 per 100,000 population. Contamination of Rhizoma Atractylodis (50% and erroneous substitution (42% were the main causes. The incidence during 2008–2012 was 0.06 per 100,000 population. Contamination of non-toxic herbs (50% and erroneous substitution (41% were the main causes. In Hong Kong, contamination of non-toxic herbs by tropane alkaloids and substitution of Flos Campsis by toxic Flos Daturae Metelis were the predominant causes of herbal medicines induced anticholinergic poisoning. Systematic studies along the supply chain are necessary to identify the likely sources of contamination. If erroneous substitution of Flos Campsis by Flos Daturae Metelis could be prevented, 40% of herbal medicines induced anticholinergic poisoning would not have occurred. Regular inspection of the retailer, continuing education for the staff in the herbal trade and repeated publicity measures will also be required. Pharmacovigilance of herbal medicines should help determine the incidence and causes of adverse reactions and monitor the effectiveness of preventive measures.

    Eruption of the Siberian Traps at the Permo-Triassic boundary [~250 Ma] produced more than 3 x 106 km3 of rapidly emplaced magma throughout a region ~2.5 x 106 km2 in extent. Dates from the New Siberian Islands of 252 ± 2 Ma (Kuzmichev & Pease, 2007) indicate that Siberian Trap-related magmas are found ~500 km to the east of where they are generally shown to terminate to the west of the Lena River. Cenozoic opening of the Eurasian Basin would account for some of this discrepancy. A Siberian Trap mantle plume in an absolute reference frame fixed to the present day location of the Iceland hot spot, tracks through time across the Taimyr Peninsula region during the Late Triassic period and then to north of the Severnaya Zemlya archipelago by the end of the Middle Jurassic. With the exception of some Middle Triassic dates from the Taimyr Peninsula there is no apparent expression of a hot spot track during the this period. Motion of Laurasia in a paleomagnetically controlled reference frame has the Franz Josef Land archipelago over the fixed hotspot from about 155 Ma to 147 Ma prior to the early phase of the High Arctic Large Igneous Province [HALIP], generally taken to be 130 Ma to 120 Ma. Campsie et al (1988) have one date of 145 Ma from samples collected by Fridthof Nansen in 1895-1896 on Solsberi Island. Dibner et al (1988) have a dozen ages from dolerite samples from various islands spanning the period 175 ±12 Ma to 138 ±10 Ma with five of them between 158 Ma to 144 Ma. During the Late Jurassic into the earliest Cretaceous the track of the fixed hotspot follows the future margin of the Barents Shelf just inboard of a reconstructed Lomonosov Ridge. By the end of the Valanginian, the hotspot tracks curves slightly, mimicking the southern curve of the Lomonosov Ridge off North America. The early phase of the HALIP moves the region of the northern Ellesmere Island over the hotspot while forming the Mendeleev and Alpha ridges. By middle Albian time, the Siberian Traps

    Full Text Available The criopreservation involve the stock of the vegetal material at low temperatures (-196°C in liquid nitrogen, in thermal conditions in which the division of cells and metabolic processes slow down, thus that the samplings may be conserved for long periods without suffering any genetic modifications. This stock technique is applied till present only on 80 vegetal species, keeping their seeds and vitrocultures preponderantly; researches were made regarding the maintenance of pollen in liquid nitrogen.The mature pollen, able to resist a higher degree of desiccation, may be conserved at low temperatures, without criopreservation. It was made researches on criopreservation of rise, maize, wheat, roses, sun flower and soy pollen. Our study purpose was to follow the impact of liquid nitrogen (-196°C about on viability of some cultured and ornamental species. The designed time of criopreservation it was 30 minutes and 7 days, using the TTC (tripheniltetrazole chloride method which allows testing the viability of vegetal material based on dehydrogenase activity.It was observed at Petunia hybrida species, that the pollen viability was low - in relevance with the witness represented from the pollen which was not resigned to the nitrogen liquid treatment - between percentage limits of 3.5-8%, in the case when the vegetal material was submersed 30 minutes in liquid nitrogen and 7.5-14.5% 7 days at (-196°C. The submersing of Nicotiana alata var. grandiflora species at 7 days, determined a low viability with 11.53%. The following two studied species Cucurbita and Hosta were proved to be the most resistant at submersing and maintenance in liquid nitrogen. The most affected pollen was Campsis radicans species. At Datura stramonium species was observed 2.59% a low viability of pollen, after 30 minutes of liquid nitrogen treatment, was 19.56%, after 7 days of submersing, the most pollen granules losing completely their viability.

    The main vine plant species for the three-dimensional greening in the urban area of Chengdu, capital of Sichuan Province, China, were investigated based on the application of analytic hierarchy process (AHP). Eight resistant indices, four growth indices, five ecology indices, and five aesthetics indices were selected to establish a comprehensive evaluation index system for these vine plant species. It was concluded that the key species among the main vine plants suited for three-dimensional greening in the urban area of Chengdu were Parthenocissus tricuspidata ,Rosa multiflora ,R. Chinensis,Wisteria sinensis ,R. Banksiae, P. Himalayana ,P'. Henryana, and Mucuna sentpervirens ; the main supplement species were Pueraria lo-bata , Bougainvillea spectabilis , Trachelos permum jasminoid.es , Vitis vinifera , Campsis grandiflora , Hedera nepalensis var.
