Abstract通过野外观察和人工授粉试验方法;对云南省文山州西畴县法斗分布区片断化生境中濒危植物滇桐(Craigia yunnanensis)的传粉生物学特征和繁育系统进行研究。结果表明:滇桐每个聚伞花序有2~9朵两性花;单花花期为3~4d;单花雌雄蕊在时空上有一定的隔离;杂交指数(OCI)>4;花粉-胚珠比(P/O)为1381±53;有效传粉昆虫为大头丽蝇(Chrysomyia megacephala);同株异花授粉结实率低;滇桐的繁育系统属于异交为主;部分自交亲和;传粉过程需要传粉者;自然状态下滇桐的座果率(56.67%±3.85%)和结籽率(6.26%±0.75%)均较低;而异株异花授粉均可显著提高座果率及结籽率(P<0.01);这与当前片断化生境中传粉昆虫少、效率低下等有关;表明生境片断化正在影响滇桐植株的早期生殖成功。
