任豆种子质量分级标准的初步研究

Preliminary study on the seed quality classification standard of Zenia insign

对不同种源的23份任豆种子进行净度、发芽率、千粒重及含水量指标的测定,利用正态分布曲线分级方法对任豆种子进行种子质量分级标准的制定。结果表明,任豆种子质量等级可划分为3个等级,正态分布曲线法方法严谨,并能方便人为地控制种子的质量,是作为制定种子质量分级标准的一种合理方法。

In order to establish the quality classification standard of Zenia insign seeds,23 provenances of Zenia insign seeds were selected as tested materials and their purity,grain weight,1 000-grain weight,germination,moisture content were determined and analyzed through normal distribution curve.The result showed that the grade of Zenia insign seeds can be divided into 3 levels.The normal distribution curve grade method was a reasonable method for establish the quality classification standard of seeds which was based on sufficient scientific basis and was convenient to control the quality of seeds artificially.
