种皮颜色对乌拉尔甘草种子质量的影响

乌拉尔甘草种子中存在着颜色的差异,可以分为绿籽与黑籽。为了确定不同颜色甘草种子的使用价值,为乌拉尔甘草的清选分级及选购提供参考,比较了绿籽与黑籽的千粒重、种子直径、电导率、发芽率、硬实率、活力指数、ATP、TTC及种子带菌情况的差异,结果表明,绿籽的硬实率、发芽率、活力指数、ATP活力、TTC活力等均显著高于黑籽,内外部带菌种子比率、电导率则显著低于黑籽,说明绿籽质量要明显高于黑籽。

Effect of Seed-coat Color on Seed Quality of Glycyrrhiza uralensis Fisch.

There is difference in seed-coat color of Glycyrrhiza uralensis Fisch.,including black seeds and dark green seeds.To define the useful value of different color seeds and supply reference for seed grading and trading in Glycyrrhiza uralensis Fisch,Three different licorice seeds lot were each divided into two groups(black and dark green seed color).,Thousand-grain weight,seed size,hard seeds rate,germination percentage,vigor index,conducting rate,TTC,ATP and fungi-infected seeds rate were tested and compared.The result showed that seed vigor of dark green seeds in Glycyrrhiza uralensis Fisch.were much better than that of black seeds,which have lower hard seeds rate,germination percentage,vigor index,ATP and TTC,higher conducting rate.Black seeds were also infected by more fungi than the dark green seeds.So quantity of green seeds is obviously superior to black seeds.
