大豆种子颜色与种子活力的相关性分析

Correlation Analysis between Seed Color and Seed Vigor of Glycine max

为了解大豆种子颜色与种子活力的关系,在标准、低温、干旱胁迫条件下比较不同颜色大豆种子的发芽指标、种子生活力、浸出液电导率,用模糊隶属函数法对大豆种子进行综合评价。结果显示:在三种处理条件下混合色大豆种子的发芽率、发芽指数均显著高于黄绿色和黄色大豆种子;三种颜色大豆种子的生活力差异不显著;在低温和干旱胁迫处理下混合色大豆种子的发芽势与黄绿色大豆种子的发芽势、黄色大豆种子的发芽势的差异不显著;在标准发芽条件下混合色大豆种子的发芽势与黄色大豆种子的发芽势差异性极显著;说明颜色对大豆种子发芽势的影响没有低温和干旱胁迫的影响大。混合色大豆种子的浸出液电导率显著低于其他两种颜色的大豆种子;模糊隶属函数综合评价混合色种子的D值最大,黄色种子的D值最小,说明混合色种子活力>黄绿色种子活力>黄色种子活力,大豆种子颜色与种子活力极显著相关。本文为大豆种子选择、清选、加工提供了理论依据。

In order to understand the relationship between soybean seed color and seed vigor,the germination index,seed viability and conductivity of leaching solution of soybean seeds with different colors were compared under standard,low temperature and drought stress,and the soybean seeds were comprehensively evaluated by fuzzy membership function method.The results showed that the germination rate and germination index of mixed color soybean seeds were significantly higher than those of yellow green and yellow soybean seeds;There was no significant difference in viability among the three colors of soybean seeds;Under low temperature and drought stress,the germination potential of mixed color soybean seeds was not significantly different from that of yellow green soybean seeds and yellow soybean seeds;Under standard germination conditions,the germination potential of mixed color soybean seeds was significantly different from that of yellow soybean seeds;It shows that the effect of color on soybean seed germination potential is not as great as that of low temperature and drought stress.The conductivity of the extract of mixed color soybean seeds was significantly lower than that of the other two colors;The D value of mixed color seeds is the largest and the D value of yellow seeds is the smallest,which indicates the following relationship:mixed color seed vigor yellow green seed vigor yellow seed vigor.Soybean seed color is significantly correlated with seed vigor.This paper provides a theoretical basis for soybean seed selection,cleaning and processing.
