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。
Objective: To explore the germplasm characteristics of different Alisma orientale germplasm resources, and to provide theoretical and practical basis for the authentic study of Alisma orientalis and the implementation of Alisma orientale GAP production. Methods: Based on the introduction and cultivation of germplasm from different sources, the biological characteristics, plant characteristics and quality of the germplasm were observed and studied. The quality tests and special studies for three years were conducted. Results: There were significant differences in the biological characters, plant characteristics and medicinal quality among the three kinds of Alisma orientalis germplasm collected from Jianzze, Chuanzai, and Alisma orientalis. CONCLUSION: Jianzhe is the same species as Jiangzhejiang. The original plants are all Alisma orientalis of Alisma orientalis, but belong to different species of the same genus. The plant of Alzheimer’s disease is A.plantago-aquatica.
