甘草种子质量检验方法研究

Testing methods for seed quality of Glycyrrhiza uralensis

目的:研究甘草种子质量检验方法,为甘草种子质量检验规程及质量分级的制定提供依据。方法:参考国际植物种子检验规程和中国农作物种子检验规程的方法对不同产地甘草种子质量进行测定。结果与结论:初步建立甘草种子扦样、净度、真实性鉴定、千粒重、发芽率、含水量及生活力7项指标的检验方法。

Objective ： The aim of this study was to optimize the testing methods for seed quality, and to provide a basis for establishing seed testing rules and quality grading standard of Glycyrrhiza uralensis. Method： Referring to the International Seed Testing Rules made by ISTA and Rules for agricultural seed testing （ GB/T 3543-1995 ） issued by China, the seed quality of G. uralensis from different collection areas was measured. Result and conclusion： The seed testing methods for quality items of G. uralensis, including sampling, purity analysis, verification of genuineness, weight of 1 000 seeds, percentage germination, moisture content and seed viability of G. uralensis had been initially established.
