摘　　要：本文研究了丹参种子不同采收部位和采收时间对种子数量和质量的影响，以及温水、高锰酸钾溶液、氯化钙溶液浸种等前处理方法对提高种子发芽率的作用。研究表明：主果穗的种子质量总体上好于侧果穗，果穗中下部的种子质量好于果穗上部，果穗上1／2～2／3果壳枯黄时进行采收才能收获的较多优质的种子。温水、高锰酸钾溶液和氯化钙溶液浸种处理对提高丹参种子发芽率都具有一定的效果，但最佳处理时间略有不同。因此，为提高收获丹参种子的质量，应尽可能在果壳半数以上至三分之二果壳枯黄时采收主果穗种子，并对果穗上端的种子进行去除。为提高陈化种子发芽率以温水浸种24h或0．3％的高锰酸钾溶液浸种6h处理为宜。The influences of harvesting position and time on Salvia mittiorrhiza seeds quanmy ana quauty, ann the seeds germination rate improving effects of different previous processing methods such as soaking seeds in warm water,K2Mn04 solution, CaC12 solution, etc. have been systematically studied in this paper. Results showed that the quality of seeds harvested on main fruit clusters was generally better than that on branch ones, while the seeds produced by the middle and back parts of fruit clusters were superior to those on the forepart of the clusters. Larger amount of high quality seeds could be obtained when 1/2 - 2/3 seed vessels of fruit cluster turns yellow. Immersing seeds in warm water,K2MnO4 solution and CaC12 solution are all beneficial to germination rate,but the optimum processing way is different. Soaking in warm water for 24 h or in 0. 3% KEMn04 solution for 6 h presents obvious advantage over the other methods.
