[目的]研究内生真菌孔球孢霉AL12号菌株对茅苍术组培苗生长及其代谢产物器官分配的影响。[方法]将内生真菌AL12与茅苍术组培苗进行共培养,比较感染前后茅苍术叶、根重量差异,检测接种AL12的组培苗中纤维素、半纤维素、木质素以及可溶性糖在叶片和根中的分布,并利用气相色谱分析挥发油组分。[结果]茅苍术与AL12共生后,与对照组相比,其组培苗叶片和根的鲜重和干重均有明显增加,且叶片木质素和可溶性糖含量增加,根部纤维素、半纤维素、木质素、可溶性糖及挥发油含量均有提高。[结论]该研究结果表明与AL12共生有利于茅苍术根部发育且能促使药用成分向根中转移、积累。
[目的]研究內生真菌孔毬孢黴AL12號菌株對茅蒼術組培苗生長及其代謝產物器官分配的影響。[方法]將內生真菌AL12與茅蒼術組培苗進行共培養,比較感染前後茅蒼術葉、根重量差異,檢測接種AL12的組培苗中纖維素、半纖維素、木質素以及可溶性糖在葉片和根中的分佈,併利用氣相色譜分析揮髮油組分。[結果]茅蒼術與AL12共生後,與對照組相比,其組培苗葉片和根的鮮重和榦重均有明顯增加,且葉片木質素和可溶性糖含量增加,根部纖維素、半纖維素、木質素、可溶性糖及揮髮油含量均有提高。[結論]該研究結果錶明與AL12共生有利于茅蒼術根部髮育且能促使藥用成分嚮根中轉移、積纍。

[Objective] To examine the effect of endophytic fungi ALl2 (Gilmaniella sp.) on metabolites distribution in organs of Atractylodes lancea. [Method] Endophytic fungi ALl2 was inoculated on Atraetylodes lancea plantlets in tissue culture, and the distribution of cellulose, hemicellulose, lignin, soluble sugar in leaves and roots of the inoculated group were detected. The weight of leaves and roots were compared. Gas Chromatography was used to analyze the volatile oil components. [Result] Compared with the control group, the average fresh weight and dry weight of leaves and roots of A. lancea which had been symbiosed with ALl2 increased significantly. The content of lignin and soluble sugar increased in the leaves of the inoculated group, and the content of cellulose, hemicellulose, lignin, soluble sugar and volatile oil also increased in roots. [Conclusion] The results indicate that symbiosed with ALl2 is benefit for the development of A. lancea roots and can promote the transfer and accumulation of the medicinal components to the roots.
