北柴胡和狭叶柴胡的萌发试验研究

目的：提高北柴胡和狭叶柴胡种子的发芽率,加大黑龙江省道地药材的开发力度。方法：采用40℃温水浸种8h后,流水冲洗4h;150w微波辐射25s（北柴胡）、20s（狭叶柴胡）;柳枝浸出液为萌发剂;浓H2SO4浸种2s,同时培养未经处理的种子作为对照组。结果流水组两种柴胡的发芽率分别为82%、86%;微波组发芽率分别为77%、75%;柳浸组发芽率分别为67%、72%;浓硫酸组发芽率分别为45%和35%;对照组发芽率41%、47%。结论：大规模播种可采用40℃温水浸种8h,流水冲洗4h,150w微波辐射25s（北柴胡）、20s（狭叶柴胡）,采用柳枝浸出液为萌发剂均可提高发芽率。

Study on the Germination Experiment Rate of Chinese Thorowax and Bupleurum Scorzonerifolium Willd

Objective： To improve seed germination rate of Chinese Thorowax and Bupleurum scorzonerifolium willd and increase the development of famous-region drug in in Heilongjiang. Method： The seeds were washed for 4 hours after they were soaked in a warm water （40~C）; Chinese Thorowax was radiated for 25 seconds by microwave and Bupleurum scorzonerifolium Willd 20 seconds; the germinant was the leaching solution of babylon weeping willow branchlet; the seeds were dipped for 2 seconds in the concentrated sulphuric acid; and the untreated seeds served as a control group. Results： The seed germination rate was 82% and 86% by the running water; it was 77% and 75% by microwave; it was 67% and 72% by the leaching solution of babylon weeping willow branchlet; it was 45% and 35% by the concentrated sulphuric acid; it was 41% and 47% in the control. Conclusion： The seed germination rate was improved by the running water, microwave, and the leaching solution of babylon weeping willow branchlet.
