紫丹参传粉生态学研究
Pollination Ecology of Radix Salvia yunnanensis
摘要:
紫丹参为云南省地方习用药材，本文对紫丹参的开花物候、花部特征、繁育系统及传粉方式进行初步研究。结果表明，紫丹参有长达5个月的花期，单花花期可持续30~50 d；花粉–胚珠比(P/O)为6509.67，杂交指数(OCI值)为4或5，繁育系统为自交亲和但需要传粉者完成传粉的兼性异交型，不存在无融合生殖现象。
Abstract:
Radix Salvia yunnanensis is a local traditional medicine in Yunnan. The concept of flowering phenology, floral syndrome, breeding system and pollination biology of Radix Salvia yunnanensis were primarily analysed in the paper. Study and observation show that the floral longevity of Salvia yunnanensis lasts for 5 months, the floral longevity of a single flower lasts for 30~50 d; P/O ratio is about 6509.67 and OCI is 4 or 5. The results of breeding experiment demonstrated that Radix Salvia yunnanensis is xenogamous and self-compatible. Agamospermy is almost nonexistent in Radix Salvia yunnanensis.
