【摘要】 药用植物丹参SalviamiltiorrhizaBge.在自然授粉中结实率约为 8%。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 %。更多还原

【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%.更多还原
