摘　　要：[目的]通过研究不同温度、不同发芽床等条件对川党参种子萌发的影响,找出川党参种子发芽的最佳基本条件,从而为川党参的规范化栽培提供一定的依据。[方法]采用常规的发芽试验方法进行试验,不同温度(15,20,25,30,15/25,20/30℃)和不同发芽床(纸间、纸上、砂间、砂上)等处理对川党参种子进行发芽试验,测定发芽率和发芽指数。[结果]在25℃下川党参种子发芽率在第8天达到高峰,在15℃下川党参种子发芽率最低。发芽床以砂上为最佳,砂中为最差。[结论]在25℃进行砂上培养是川党参种子萌发检验的最适条件。Objective： To fred out the condition for the germination by studying the effects of temperature and seed bed on Codonopsis tangshen, and offer the basis for standardized culture of C. tangshen .Method：The general germination methed.Gemaination rate and index of C. tangshen seed were determined, The germination of C. tangshen seed was under following conditions： treatments under different temperature （15,20,25,30,15/25,20/30 ℃） and different gemaination cultivation conditions （on top filter paper , between filter paper , on top sand , between sand）. Result：Germination rate of the seeds reached the maximal within 8 days at 25 ℃. TS was the best seed bed for C. tangshen seed. S was the west. Conclusion： The optimal condition for the germination of the seed of is as follow： on top sand, and 25 ℃ under light.
