| 摘 要： | 药用植物丹参（Salvia miltiorrhiza Bge．）在自然授粉中结实率约为8％。其花柱的授粉率较高的，可达76％，为结实率的9．5倍，柱头上的平均花粉量为3－12个，但多数为自花花粉，散粉期花粉活力较高。从不同处理下结实率实验看，丹参的有性繁殖主要依靠异花授粉，其自花授粉的结实率为0．6％。作者认为，在影响结实率的诸多因素中，异花授粉的效率以及植物对异花授粉的依赖程度是重要因素。

| Abstract: | The pollination biology of Salvia miltiorrhiza has been studied.Its seed set was 8% in natural conditions.the pollination rates were high to 76%,9\^5 times of its seed set.The mean number of pollen grains per stigma ranged from 3 to 12,most of the pollen grains were from self-pollination.The pollen viability was strong in the pollen period.The breeding system of Salvia miltiorrhiza was dominantly xenogamous,and autogamy was about 0\^6%.We consider that the limitation and dependence of xenogamy are important factors among the factors influencing seed set. |
