以源于湖北省不同产区的白花前胡种子为试材,以净度、千粒质量、含水量、发芽率为指标,采用K聚类分析的方法制定分级标准。结果表明:综合考虑前胡种子检验快速有效、实用性、可操作性,可将湖北省前胡种子分为一级种子发芽率≥60%、千粒质量≥2.0g、净度≥90%、含水量≤10%;二级种子发芽率60%~50%、千粒质量2.0~1.8g、净度90%~85%、含水量≤11%,一、二级为合格种子,三级为不合格种子等3个等级。
Using the seeds of P. przewalskii from different regions of Hubei province as test materials, the standard of K - cluster analysis was established by using the indexes of clarity, grain weight, water content and germination as indexes. The results showed that the germination percentage of first seeds of Peucedanum acutus in Hubei Province was ≥60%, the quality of 1000 seeds ≥2.0g, and the clarity of ≥90%, considering the rapid, effective, practicability and maneuverability of Peucedanum seeds test. The water content is less than or equal to 10%, the germination rate of secondary seeds is 60% -50%, the quality of 1000 seeds is 2.0-1.8g, the clarity is 90% -85%, the water content is less than or equal to 11% Unqualified seeds and other three levels.
