[目的]为了研究丛枝菌根对黄檗叶片氮素及含氮代谢物质含量的影响.[方法]通过盆栽试验,用摩西球囊霉、幼套球囊霉、地表球囊霉、透光球囊霉4种丛枝菌根真菌接种黄檗一年生实生苗.[结果]黄檗幼苗形成丛枝菌根后,黄檗叶片氮素含量增加,接种摩西球囊霉的苗木叶片氮素含量比对照提高了1.28 ～1.60倍,植物体内硝酸还原酶的活性增强,可溶性蛋白含量、植物体内吲哚乙酸的含量增加.[结论]丛枝菌根能够增强黄檗氮素代谢能力,促进氮素吸收及含氮物质合成代谢,有利于黄檗生长发育.%[Objective] The research aimed to explore the effects of VA mycorrhiza on the content of nitrogen and nitrogenous matter of amur cork trees(Phellodendron amurense Rupr. ). [Method] The annual seedlings were inoculated with four arbuscular mycorrhiza fungi through potted experiments. [Result] VA mycorrhiza obviously increased the content of nitrogen and nitrogenous matter. The nitrogen content of the leaves increased significantly through infection by VA mycorrhizal fungi. With the inoculating with G. Mosseae, the nitrogen content of seedlings increased by 1.28 to 1. 60 times. VA mycorrhiza also enhanced the activity of nitric acid reductase of the plants, and the content of soluble protein and the proportion of the indole acetic acid. [ Conclusion ] VA mycorrhiza can enhance the metabolic ability of amur cork trees and the photosynthesis characteristics, and promote the growth of the whole plant.
