摘要
对乌岩岭国家级自然保区的浙江雪胆(Hemsleya zhejiangensis)种群调查发现,浙江雪胆雌雄异株,花小,雄蕊不发达,不利于虫媒或风媒传粉;浙江雪胆原发现地在毛竹林中,郁蔽度高,土壤腐殖质少,且竹子根茎将土壤严重网格化,限制了浙江雪胆的生长发育;浙江雪胆分布在溪涧边,易受溪水冲刷,这三方面共同作用导致浙江雪胆种群萎缩。
Hemsleya zhejiangensis （Cucurbitaceae） is an endemic climbing species in Zhejiang Province. Investigations on population of H. zhejiangensis in Wuyanling National Nature Reserve of Zhejiang showed that H. zhejiangensis is a dioecious plant with small flowers and short stamens, making difficult for insect and wind pollination. The result also demonstrated that the first place of finding H. zhejiangensis was in a bamboo grove with limited sunshine and humus, rhizomes and root of bamboos made grid of soil. The factors above-mentioned would be the causes of decrease of H. zhejiangensis population.
