泽泻不同种质资源特性比较研究

Comparative studies on genetic resource of characteristics of Alisma

目的:探讨不同泽泻种质资源的种质特性,为泽泻地道性研究及实施泽泻GAP生产提供理论与实践依据。方法:在对不同来源的种质进行引种栽培的基础上,观察研究其生物学特性与植株特征及其品质,连续3年品质试验及专题研究。结果:建泽泻、川泽泻和江西泽泻3种泽泻种质间的生物学性状、植株特征及药材品质等具有显著差别。结论:建泽泻与江泽泻是同种植物,原植物都是东方泽泻Alisma orientalis,而与川泽泻属同属不同种的植物,川泽泻原植物是泽泻A.plantago-aquatica。

Based on the introduction and cultivation of Alisma germplasm which were from Fujian, Jiangxi and Sichuan provinces, the biological characteristics, morphological characteristics and quality were observed and studied. After three-year continuous experiment and monographic study, there were remarkable difference in the biological characteristics, morphological characteristics and product quality of Fujian Alisma, Sichuan Alisma and Jiangxi Alisma. Fujian Alisma and Jiangxi Alisma were the same plant species of A. orientalis, whereas Sichuan Alisma and Fujian Alisma were the different plant species of A. plantago-aquatica. The study results will provide the theoretical and practical basis for the genuine medicinal materials research and good agricultural practice （GAP） of Alisma.
