中药种子千粒重、健康度是低温库中药种子质量评估的重要指标,是中药种质资源低温保存技术体系中种子管理的重要组成部分,对种子的采集和管理具有重要指导意义.本文对国家中药种质资源库收集的具有代表性的189科926属2 317种共计10 062份中药种子的千粒重及健康度进行检测,并采用Excel 2016、SPSS 20.0及Ori-gin 2021b等软件进行数据分析.结果表明:中药种子千粒重多数在0 g<X<10 g范围内,占比为59.85%,且不同科中药种子的千粒重分布范围存在较大差异;经初次净选后,中药种子健康度70%以上的占比为89.55%,种子空瘪、虫蛀等是引起种子健康度低的主要原因.依据千粒重、健康度分析结果更新中药种子管理方案,采集时按种子千粒重的分布范围并结合科的健康度综合制定种子采集数量或重量标准,种子净选和质量评估时先确定种子的净选结果,再选择适宜的方法净选后进行种子健康度检测.本文为制定中药种子采集和管理技术规范提供了科学依据,完善了中药种质资源低温保存技术体系,为中药种子科学保存研究奠定了基础.
Thousand-grain weight and health degree of traditonal Chinese medicine(TCM)seeds were important indexes for evaluating the quality of TCM seeds in low temperature storage,and they were important parts of seed management in the technical system of cryopreservation of TCM germplasm re-sources,which had important guiding significance for seeds collection and management.In this arti-cle,the thousand-grain weight and health degree of 10 062 TCM seeds from 189 families,926 genera and 2 317 species were tested in the State Bank of Chinese Drug Germplasm Resources.The data were analyzed by Excel 2016,SPSS 20.0 and Origin 2021b.The results showed that the thousand-grain weight of TCM seeds were mostly in the range of 0 g<X<10 g,accounting for 59.85%.And the thousand-grain weight distribution of TCM seeds of different families had great differences.After the initial cleaning,89.55%of TCM seeds health degree were more than 70%,and the main reasons for the low seed health were empty and moth damage.According to the analysis results of thousand-grain weight and health degree,the management scheme of TCM seeds was updated.The standard of seed collection quantity or weight was formulated according to the distribution range of thousand-grain weight of seeds and the health degree of the family.In the process of seed purification treatment and quality assessment,the seed purification results should be determined first,and then the appropriate purification method and the seed health detection method should be selected.This work provided a sci-entific basis for the formulation of the technical specifications of TCM seeds collection and seed man-agement,improved the technical system of low temperature preservation of Chinese medicine germ-plasm resources,and laid a foundation for the scientific preservation of TCM seeds.
