摘 要 ：分析了全缘金粟兰（Chloranthus holostagius）弥勒居群的繁殖生物学，对其居群结构、花发育、有性生殖及无性繁殖过程进行了较为仔细的观察分析。结果显示，全缘金粟兰主要分布在具有良好常绿阔叶林分布之山谷的北坡，个体在居群内呈群聚式分布。在自然条件下，全缘金粟兰以有性生殖为主，居群更新良好，由种子萌发至性成熟约需3～4年的时间，性成熟植株具有1条项生和有时具有2或4条侧生的穗状花序。居群内平均每个个体可有1.91条花序，每条花序平均可有28.07朵花。全缘金粟兰为异花授粉植物，它具有一系列和异花授粉相适应的形态结构和机制，其传粉昆虫为蓟马。在自然条件下全缘金粟兰主要由顶生花序结实，侧生花序虽能正常开花，但常不结实；单株的果实数在0～30枚之间，平均为12枚；结实率在0％～96％之间，平均为 39％。全缘金粟兰近交亲合但不存在自花授粉。在环境条件适合时，植株可以通过分蘖进行营养繁殖。

Abstract:The reproductive biology including population structure, sexual reproduction as well as vegetative propagation of Chloranthus holostagius has been observed and analysed in this paper. The result shows that in natural conditions, Chloranthus holostagius is mainly distributed on northern slopes of valleys with good every-green broad-leaved forests. The plant shows a kind of aggregated distribution pattern. The plant mainly processes sexual reproduction, and population regeneration is good. It takes about 3- 4 years from seed germination to sex mature. The matured individual has usually 1 terminal and sometimes 2 or 4 lateral spikes. In population, on an average, each individual can produce 1.91 spikes. Each spike has 28.07 disexual flowers. Chloranthus holostagius is allogamy and has a series of adaptable structures and morphologies. Its pollinator is Thropdae.
