山茶科珍稀濒危植物圆籽荷的繁殖生物学研究

圆籽荷是中国特有的单种属稀有植物,历年来对其研究较少.对圆籽荷的分布现状,生境,有性生殖过程,种子散布等进行了观察分析,结果显示,在自然条件下,圆籽荷主要以有性生殖为主,能正常地开花结实,同时在一些环境下存在着分蘖方式的营养繁殖;圆籽荷为严格的异花授粉植物,昆虫主要为蜂类起重要的传粉作用,种子主要靠重力散布.

A survey on the reproductive biology of the Apterosperma oblate H.T.Chang,an endemic and rare plant from theacea

Apterosperma oblate H.T.Chang is an endemic and rare species of Theacea and little is known about it before.Investigations on the environmental condition,detailed distribution,sexual reproduction and the distribution of seeds were carried out by the authors and reported in this paper.The result shows that the plant mainly processes sexual reproduction,and in some conditions,the plant can carry vegetative propagation by tillering.The plant is a strict cross-pollinated plant,the bees are main pollinators and the seeds are mainly distributed by gravitation.
