栀子种子质量标准研究

Quality Standards of Gardenia Seeds

为制定栀子种子质量标准,对收集的55份栀子种子进行净度、发芽率、千粒重、含水量、生活力的测定,采用SPSS 13.0软件,利用K类中心聚类分析方法制定质量标准。结果表明,栀子种子被分为三级,以发芽率、生活力、千粒重作为主要的分级标准,净度和含水量作为次要的标准,其中净度≥82.09%、发芽率≥72.75%、千粒重≥4.12 g、生活力≥97.83%、含水量≤10.24%为一级品;净度75.65%-82.09%、发芽率66.83%-72.75%、千粒重3.30-4.12 g、生活力96.80%-97.83%、含水量10.24%-10.28%为二级品;净度62.21%-75.65%、发芽率57.80%-66.83%、千粒重2.58-3.30 g、生活力〈96.80%、含水量≥10.28%为三级品,一级、二级为合格品,三级为不合格品。

In order to set the quality standards of the gardenia seed, 55 gardenia seeds were collected to determine the purity, germination rate, thousand-seed-weight, moisture content and viability by SPSS 13.0 software and K class cluster analysis. Results showed that gardenia was divided into three grades. Taking germination rate, viability and thousand seed weight as the main grading standards, purity and moisture content as the secondary standard, the first grade was with purity above 82.09%, germination rate above 72.75%, thousand seed weight above 4.12 g, viability no less than 97.83%, moisture content less than 10.28%. The second grade was with purity 75.65%-82.09%, germination rate 6.83%-72.75%, thousand seed weight 3.30-4.12 g, viability 96.80%-97.83%, moisture content 10.24%-10.28%. The third grade was with purity 62.21%- 75.65%, germination rate 57.80%-66.83%, thousand seed weight 2.58-3.30 g, viability no less than 96.80%, moisture content no less than 10.28%. The first and second grades were qualified products, and the third grade was unqualified products.
