紫锥花紫锥菊(紫锥菊紫锥菊L.)是一种重要的药用植物，含有具有抗病原性的酚类和烷胺类物质。本研究旨在探讨丛枝菌根(AM)定植对紫花草生理生化特性的影响。推测AM侵染能促进紫叶锦鸡儿的生长和次生代谢。在这方面，进行了为期13周的因子温室试验，接种(或不接种)AM真菌Glomus intraradices Schenck&Smith。结果表明，AM侵染显著增加了地上部和根部的质量，增加了根部蛋白质和大部分酚类物质的浓度。因此，菌根的选择特性可以通过诱导次生植物药用代谢物的产生，在优化紫球藻的生长方面发挥重要作用。
Purple coneflower, Echinacea purpurea (L.) Moench, is an important phytomedicinal species that contains phenolics and alkamides with antipathogenic properties. This study aimed to examine the effect of arbuscular mycorrhizal (AM) colonization on the physiology and biochemistry of E. purpurea. It was hypothesized that AM colonization enhances the growth and secondary metabolism in E. purpurea. In this regard, a 13-week factorial greenhouse experiment was performed with E. purpurea, inoculated (or not) with the AM fungus Glomus intraradices Schenck & Smith. Overall, the results indicated that AM colonization significantly increased the mass of shoots and roots and the concentrations of proteins and most of the phenolics in the roots. Hence, the selected trait of mycorrhiza could play an important role in optimizing the growth of E. purpurea by inducing the production of secondary phytomedicinal metabolites.
