对国产葛属PueraraiDC.7种1变种植物花粉的光学显微镜、扫描电镜以及2种1变种的透射电镜观察表明:花粉形态各具特征;表面纹饰类型包括穿孔状(一般直径小于网脊直径或稍等,孔穴中无或少颗粒)、细网纹(网眼直径约与网脊直径相等或略细,网眼内具颗粒)、粗网纹(网眼直径大于网脊直径、网眼内具成片的众多颗粒);孔沟类型为具孔膜或孔盖,孔膜常成孔桥.上述结果,表明葛属植物7种1变种的花粉形态是有区别的,从覆盖层等形态结构可以推测其亲缘关系,亦可看到部分的演化. 相似文献

Four new species, Cruddasia craibii, Flemingia kradungensis, F. tiliacea and Pueraria maesenii are described and illustrated. The following new combinations are proposed: Cruddasia pinnata; C. laotica, Dolichos grahamianus; D. oxyphyllus; Dolichovigna pilosa; Erythrina stricta var. suberosa; Flemingia macrophylla var. sootepensis; Pueraria candollei var. mirifica; Shuteria suffulta var. sinensis and Vigna radiata var. grandiflora. Pueraria rigens is moved to the tribe Millettieae (= Mellettia rigens). 相似文献

? Premise of the study: Pueraria (Leguminosae, Papilionoideae) is native in East Asia, South Asia, Southeast Asia, and Oceania and is well known as a rampant invasive weed in the southeastern United States (P. montana; better known as kudzu), but relatively little is known about its early evolution and biogeographic origin. ? Methods: On the basis of comparative analyses of the fruit and leaflet architecture of closely related extant and fossil taxa, we studied the fossil history and biogeography of Pueraria. ? Key results: Fossil Pueraria is recognized on the basis of distinctive fruit and foliage from the Mio-Pliocene of middle latitudes in China, Japan, Abkhazia, and Croatia. Recognition of P. miothunbergiana from the Mio-Pliocene of China and Japan is reinforced by a trifoliolate leaf as well as isolated lateral and terminal leaflets. Pueraria shanwangensis sp. nov. represents the first recognition of fossil Pueraria fruits. This fruit species co-occurs with P. miothunbergiana in the Middle Miocene Shanwang flora and possibly represents the same population. Pueraria maxima (Unger) comb. nov., previously named as Dolichites maximus or Desmodium maximum, is recognized on the basis of leaflets from the Miocene of Croatia and Abkhazia. Other prior fossil reports of Pueraria and Dolichites are reevaluated. ? Conclusions: Pueraria had begun to diversify by at least the Middle Miocene and had spread into the Mio-Pliocene subtropical and temperate floras of the Balkan Peninsula, the Caucasus, and eastern Asia, which suggests the present diversity of this genus in tropical Asia and Oceania might have originated from the mid-latitudes of Eurasia. 相似文献

为预测入侵植物与其邻近物种间的非协同进化趋势,分别提取薇甘菊(Mikania micrantha)及其近邻种五爪金龙(Ipomoea cairica)、葛藤(Pueraria lobata)和鸡矢藤(Paederia scandens)的叶片水提液处理幼苗,对薇甘菊及其近邻种的种内、种间化感作用进行研究。结果表明,薇甘菊对3种近邻种的化感作用呈现不同趋势(SE=0.50, 0.61,–0.16),但种内存在较强的化感促进作用(SE=0.61),说明其种内化感竞争较弱;葛藤的种内化感促进作用(SE=0.32)弱于薇甘菊,种间的化感促进作用与薇甘菊相似(SE=0.52, 0.50);五爪金龙种内化感促进作用(SE=0.06)弱于薇甘菊和葛藤(SE=0.32),种间促进作用(SE=0.24)弱于薇甘菊(SE=0.61);鸡矢藤的种内、种间化感作用均表现为抑制作用(SE=–0.18,–0.07),说明种内、种间化感竞争较强。野外调查表明4种植物分布的频度和多度均表现为薇甘菊葛藤五爪金龙鸡矢藤,这与化感竞争力结果一致。可见,种内与种间化感作用在入侵植物与近邻植物的综合竞争力中扮演着极为重要的作用,这为入侵种与近邻种之间的非协同进化趋势指明了方向。 相似文献

Pueraria radix (the dried root of Pueraria plant) is known as a traditional Chinese drug. Hairy roots of Pueraria lobata (Willd.) Ohwi, P.lobata var. montana and P. phaseoloides (Roxb.) Benth. transformed by Agrobacterium rhizogenes (Riker et al .) Conn R1601 were developed directly from the surface of sterile leaves in vitro . The transformation frequency was 16.6%, 16.2% and 26.6%, respectively. All hairy roots in the three species displayed the typical phenotypes of rapid growth, highly branched and plagiotropism, and also exhibited hormone autotrophy and resistance to kanamycin.The genetic transformations were confirmed by opine paper electrophoretic analysis, rol gene PCR amplification and molecular hybridization. 相似文献

Pueraria lobata polysaccharides (PLPs) were obtained by hot water extraction using Pueraria lobata as raw material. Structural analysis revealed that PLPs may have a repetitive backbone units of →4) -α-D-Glcp (1→4-α-D-Glcp (1→. Phosphorylated Pueraria lobata polysaccharides (P-PLPs), carboxymethylated Pueraria lobata polysaccharides (CM-PLPs) and acetylated Pueraria lobata polysaccharides (Ac-PLPs) were obtained by chemical modifications of PLPs, respectively. The physicochemical properties and antioxidant activities of these four Pueraria lobata polysaccharides were studied in comparison. In particular, the clearance rate of P-PLPs exceeded 80 %, and was expected to achieve the same effect as Vc. The results showed that the effects of different chemical modifications on the antioxidant activity of PLPs varied greatly. 相似文献

Summary Iron deficiency was diagnosed in some pasture species growing on a coralline rubble soil (Troporthent) of high pH in the Solomon
Islands.
A comparative study of the response of a selection of pasture species to additions of iron indicated differential species
tolerance to iron deficiency particularly among legumes.Macroptilium atropurpureum andM. lathyroides produced good yields on this soil without additions of iron while other legume species,Centrosema pubescens, Pueraria phaseoloides andStylosanthes guianensis either grew poorly or failed to survive. 相似文献
