    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.

  4. Impact of a fixed Siberian Traps mantle plume on the tectonics of the Arctic (United States)

    Lawver, L. A.; Norton, I. O.; Gahagan, L.


    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

    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 , Vitis vinifera , Campsis grandiflora , Hedera nepalensis var. Sinensis, Euonymus fortunei, Pharbifisnil, Lonicera japonica ; the common supplement species were Cucurbita pepo var. Ovifera, Lagenaria siceraria var. Microcarpa, Epipremnum aureum , Millettia dielsiana , Quamoclit pennata , Trichosanthes rosthornii. Some constructive suggestions on the selection of vine plants in the city three-dimensional greening in Chengdu were given.%对成都市中心城区空间立体绿化中主要藤本植物的种类进行了调查,应用层次分析法(AHP),筛选出8个抗性指标、4个生长指标、5个生态指标和5个美学指标,建立了综合评价指标与其权重值体系,并对调查出的藤本植物进行评价,结果表明:成都市空间立体绿化中藤本植物主要适生种可作为骨干种的有8种:爬山虎、多花蔷薇、藤本月季、紫藤、木香花、三叶爬山虎、川鄂爬山虎、常春油麻藤;主要配置种有9种:葛藤、三角梅、络石、葡萄、中国凌霄、中华常春藤、扶芳藤、牵牛花、金银花;一般配置种或补充种有6种:观赏南瓜、观赏葫芦、绿萝、香花崖豆藤、茑萝、括楼.同时对成都
