滇黄精种子质量检验方法

Seed Quality Test Methods of Polygonatum kingianum

目的:研究滇黄精种子检验方法,为制定滇黄精种子检验规程及质量分级标准提供依据。方法:以当年采收的不同产地的滇黄精种子为样本,参照《农作物种子检验规程》,对其质量进行检验,探索滇黄精种子质量检验的方法。结果:滇黄精种子质量检验方法为种子净度分析送检样本≥2000 g,实验样品≥200 g;种子千粒质量测定选用百粒法;种子含水量测定选用高恒温烘干法,烘干时间为9.5 h;生活力测定采用0.03%2,3,5-三苯基氯化四氮唑(TTC)溶液染色,于恒温35℃下染色24 h;发芽率测定采用纸上发芽床,在25℃下黑暗培养。结论:该方法操作简便、重复性好,适用于滇黄精种子质量检验。

Objective:To optimize the testing methods for seed quality of Polygonatum kingianum,and provide basis for establishing seed quality standard of P.kingianum.Methods:The seed quality of P.kingianum from different producing areas was measured based on the agricultural seed testing.Results:The samples weight of P.kingianum were at least 2000 g for purity analysis and were at least 200 g for testing.Seed weight was determined by 100-seed method.The water content was carried out by higher temperature for 9.5 h.Seed viability was tested in 35℃for 24 h.The germination bed was filter paper,temperature was 25℃,illumination conditions was dark.Conclusion:The seed testing methods for quality items of P.kingianum have been initially established.
