| 摘 要： | 药用植物丹参Salvia miltiorrhiza Bge.在自然授粉中结实率约为80％，其花柱的授粉率较高，达到76％，为结实率的9.5倍。柱头上的平均花粉量为3－12个，但多数为来自自花的花粉，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%。

| Abstract: | The pollination biology of Salvia miltiorrhiza has been studied. Its seed set was 8% in natural conditions, the pollination rates came 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%. |
