目的:制定秦艽种子质量分级标准。方法:对从不同产地采集的24份秦艽种子进行净度、千粒重、含水量、发芽率指标的测定,统计分析数据,利用平均数加减标准差法制定秦艽种子质量分级标准。结果:以发芽率作为秦艽种子质量分级的主要指标,其他指标作为参考,将秦艽种子质量分为4个等级。结论:此方法初步制定了秦艽种子质量分级标准,可作为控制秦艽种子质量的参考标准。
Objective: To establish the quality standard of seed of Gentiana macrophylla. Methods: 24 seeds of Gentiana macrophylla collected from different habitats were tested for clarity, thousand-grain weight, water content and germination rate, and statistical analysis data were used to determine the seed quality grading standards of Gentiana macrophylla by using the mean plus or minus standard deviation method. Results: The germination rate was used as the main index of Qinhuang seed quality classification, and other indicators as a reference, the seed quality of Gentiana macrophylla was divided into four grades. Conclusion: This method preliminarily formulated the seed quality grading standards of Gentiana macrophylla, which can be used as a reference standard to control the genomic quality of Gentiana macrophylla.
