摘要
目的:制定白花蛇舌草种子质量标准。方法:对所收集的30份不同产地和不同年份的白花蛇舌草种子进行发芽率、净度、千粒重、含水量和生活力等指标的测定,使用SPSS 11.0软件,利用K类系统聚类方法制定分级标准。结果与结论:以发芽率作为主要指标,净度、千粒重和含水量作为重要参考指标,初步制订了白花蛇舌草种子质量分级标准。
Objective: To establish the quality classification criteria of Oldenlandia diffusa seeds. Method: Thirty batches of O. diffusa seeds from different provenances with different collecting time were selected. And the seed germination percentage, seed pu- rity, weight per 1 000 grains, moisture content and seed viability were determined and analyzed through SPSS 11.0 software. Result and Conclusion: Seed germination percentage was selected as the main index for classification, while seed purity, weight per 1 000 grains and moisture content could be used as references. The quality classification criteria of 0. diffusa seeds have been initially estab- lished.
