市售甘草种子发芽率分析

Analysis of the Germination Rate of Licorice Seed Sold in Market

[目的]研究甘草种子发芽率。[方法]通过对4个中药材种子市场上购入的乌拉尔甘草种子随机取样后,对种子大小、颜色等不同的组分测定其千粒重和发芽率,并对各种因素与发芽率的关系进行分析。[结果]不同来源甘草种子间发芽率的差异很大,有的达90%以上,有的种子几乎丧失发芽能力;不同来源种子的千粒重间差异不大,千粒重与发芽率间看不出明显的相关关系;不同颜色的种子中,灰绿色种子发芽率最高,深褐色种子次之,浅褐色种子最差。[结论]甘草种子的发芽率主要受种子成熟度、保存时间及保存条件的影响;正常成熟的种子为灰绿色,浅褐色和深褐色种子可能是没有完全成熟的种子。

[ Objective] The germination rate of licorice（ Glycyrrhiza aralensis） seed was studied. [ Method] 1 000-grain weight and germination rate of licorice seeds, randomly sampled form the four Chinese herbal medicine markets and classified into the groups according to seed size, color and other traits, were measured, and the relationship between a variety of factors and germination rate was analyzed. [ Results ] The results showed that there was a very significant difference in germination rate of seeds among different sources of seeds markets, and the difference in germination rate of seeds varied from more than 90% to almost non-germination capacity. ; The difference in 1 000-grain weight of licorice seed among different sources of seeds markets was small. There was no obvious correlation between 1 000-grain weight and germination rate of licorice seed. In the seeds with the different colors, the germination rate of the seed with grey green was highest; then the dark brown seed and the light brown, worst. [ Conclusion] The germination rate of licorice seeds was mainly affected by seed maturity, storage time and preservation condition. The color of normally matured seed was grey green, and the seeds with hght brown and dark brown might not be fully matured.
