摘　　要：为了建立柴胡种子质量分级标准,以便控制其质量,规范其供需市场。采用柴胡种子检验方法,测定不同来源的柴胡种子的发芽率、千粒重、净度、含水量和生活力等指标;根据K类中心聚类分析原理,使用SPSS17.0统计分析软件对数据进行了分析。最终确定了以发芽率和千粒重2项指标为主要标准,净度和含水量为参考标准的4项指标3个等级的柴胡种子质量分级标准。除去发芽率低于50%的不合格种子,25份试样中Ⅰ级有8个,Ⅱ级有11个,Ⅲ级有6个。此标准可为柴胡种子品质检验提供参考。The purpose of this research was to establish quality grading standards of radix bupleuri seeds in order to control the quality and regulate the seeds ＇ market supply and demand. In the research, five quality indicators of radix bupleuri seeds were tested including germination percentage, 1000-grain weight, neatness, water content and viability using the testing methods identified by our research group; the data were analyzed on the basis of K -means clustering algorithm with the SPSS 17.0 statistical analysis software. The research had finally set up the quality grading standards of radix bupleuri seeds totally with four indices and three grades, which took germination percentage and the 1000-grain weight as the main criteria, and the neatness and the water content as the reference. Except the seeds with germination percentage below 50%, among 25 samples, there were 8 accessions in the first grade, 11 accessions in the second grade, 6 accessions in the third grade. The standards can provide a reference for radix bupleuri seeds quality inspection.
