报道5种浓度的不同外源激素处理北柴胡和三岛柴胡种子后的发芽试验结果。赤霉素GA3、细胞分裂素6-BA和生长素吲哚乙酸IAA能促进北柴胡种子萌发，其最佳浓度均为50μg/ml，三岛柴胡种子则分别为200、100、和25μg/ml。在3种激素中，两种柴胡种子都以6－BA处理效果最好，50μg/ml的6－BA能使北柴胡种子的发育率由57.5%提高到84.5%，100μg/ml的6－BA能使三岛柴胡种子的发芽率由28.5%提高到76.0%。

Germination of the seeds of Bupleurum chinenseand SandochaihuB. falcatum activated by exogenous hormones of dif ferent concentrations was studied. The hormones used were GA3, 6-BA and IAA. The optimum concentration of the 3 hormones that activated the seed germination of B. chinense was 50μg/ml,while that for B. falcatum was 200μg/ml, 100μg/ml and 25μg/ml respectively. Among the 3 hormones, 6-BA showed the greatest effect on the 2 species of Bupleurum L. 50μg/ml 6-BA raised the germination rate of the seeds of B. chinese from 57.5 % to 84. 5 % and 100μg/ml 6-BA raised the germination rate of the seeds of B.falcatum from 28. 5 % to 76.0%.
