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℃);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.
