摘要
目的:探索天葵的系统生长发育特性及规律,研究不同发育时期天葵药用部位的构造特征。方法:在生长期对天葵不同发育时期的药用部位进行系统切片观察研究。结果:天葵药用部位上下结构不同:根顶部芦头为根茎的构造,有髓;膨大根的上部约1/3为根茎过渡区,也有髓;下部约2/3为根的构造,无髓。不同发育时期天葵药用部位显微构造有较大差别,植株从小到大其结构呈现规律增大趋势。首次发现在天葵根及根茎的木质部中都有生长轮结构。结论:建立了不同发育时期天葵的药材性状与组织学鉴别方法,为天葵药材鉴别提供依据。
Objective：To study the structural characteristics of medicinal parts at different developmental stages of Semiaquilegia adoxoides.Methods：observed on sections of medicinal parts of Semiaquilegia adoxoides at various developmental stages during growth periods.Results： There was a great difference between the upper and bottom of the medicinal parts of Semiaquilegia adoxoides： rhizome at the top of root had the structure of rhizome with pith;The upper one third of enlarged root was root-stem transition zone,also with pith;And the other two thirds of enlarged root had the structure of root without pith.The microscopic structures of the medicinal parts of Semiaquilegia adoxoides at various developmental stages presented great disparities,the structures regularly increased as the size of plant increased.It was the first time to find that there were structure of growth rings in xylem of the root and rhizome of Semiaquilegia adoxoides.Conclusion： The method of identification of characteristics and histology of medicinal parts of Semiaquilegia adoxoides at different developmental stages is established,and the results provide a basis for identification of Semiaquilegia adoxoides medicinal materials.
