目的:制定川明参种子的质量分级标准。方法:参照农作物种子检验规程方法,测定不同产地10批次的川明参种子净度、千粒重、含水量、生活力、发芽率,统计数据,利用主成分分析方法和聚类分析方法对检测结果进行分析,初步制订川明参种子质量分级标准。结果:川明参种子大致分为3类,一级种子生活力≥95%,千粒重≥8.5 g,发芽率≥20%,净度≥85%,含水量≤13%;二级种子生活力为85%～95%,千粒重为8.0～8.5 g,发芽率为15%～20%,净度为75%～85%,含水量≤13%;三级种子生活力≤85%,千粒重大多≤8.0 g,发芽率≤15%,净度≤75%,含水量≤13%。结论:目前川明参主产区种子净度均在75%以上,千粒重7.57～8.94 g,含水量11.35%～15.76%,生活力77%～97%,发芽率12.67%～22.67%,不同产地来源川明参种子的生活力、千粒重等差别较大。
Objective: To establish the quality grading standard of Chuanming ginseng. Methods: With reference to crop seed testing procedures, the seed purity, 1000-grain weight, water content, viability, germination rate and statistical data of 10 batches of Chuanming ginseng from different habitats were determined. The principal component analysis and cluster analysis were used to test the results Analysis, the initial development of Chuanmingshen seed quality grading standards. Results: The seeds of M. chinensis could be divided into three groups. The primary seed’s viability was ≥95%, the thousand seed weight was ≥8.5 g, the germination rate was ≥20%, the net density was ≥85% and the water content was ≤13% 85% -95%, 1000-grain weight is 8.0-8.5 g, the germination rate is 15% -20%, the clarity is 75% -85%, the water content is less than 13%; the third seed’s viability is less than 85% g, germination rate ≤ 15%, clarity ≤ 75%, water content ≤ 13%. Conclusion: At present, the seed purity of the main producing areas of Chuanming is above 75%, the grain weight is 7.57 ~ 8.94 g, the water content is 11.35% ~ 15.76%, the viability is 77% ~ 97% and the germination rate is 12.67% ~ 22.67% Source Chuanmingsong seed vitality, 1000-grain weight and other differences.
