目的:了解不同来源知母种子千粒重和发芽率的总体状况,并分别研究安国药材市场和知母产区的种子现状及千粒重与发芽率之间的相关性。方法:采用常规方法并结合数理统计方法对知母种子的千粒重和发芽率进行测定分析。结果:30份知母种子的千粒重和发芽率较为相近,种子总体状况良好,其中流通在安国药材市场中的15份知母种子质量无参差不齐的现象,知母产区中的15份种子质量也很稳定;相关性分析结果显示,千粒重和发芽率之间呈负相关性,但两者并无明显的相关关系。结论:市场中会有一定数量的陈种子出售,而在知母产区采收的种子则无此种现象发生,建议选择知母产区收集优质种子。

This paper aimed to understand the general situation of thousand-grain weight(TGW) and germination of Anemarrhena asphodeloides seeds from different areas.And the correlation of TGW,germination and seeds,which are sold in the Anguo Herb Market and in Anemarrhena asphodeloides production areas,were studied respectively.Routine method was adopted in the survey and analysis of TGW and germination of Anemarrhena asphodeloides seeds with mathematical statistical methods.Anemarrhena asphodeloides seeds with favorable general situation,equal TGW and germination,were divided into 30 portions.Among 30 portions,consistent quality was evaluated from seeds of 15 portions from the Anguo Herb Market and the other 15 portions from production areas.The result of comparative analysis showed that negative correlation was found between TGW and germination.However,no obvious relativity has been detected between TGW and germination.It is concluded that Anemarrhena asphodeloides seeds purchased from the market are usually old ones.The seed quality from production areas is better.So it is suggested is to purchase Anemarrhena asphodeloides seeds from its production area.
