[摘要]
从38株野生金线莲中共分离获得29株菌根真菌,其中丝核菌类(Rhizoctnia sp.)真菌7株,结合菌株形态、融合群测定及5.8S rDNA-ITS序列分析,鉴定结果如下:J1、F1、F7属于双核丝核菌AG-P融合群,F1、F7为AG-P融合群中的同一亚群,J1为不同的亚群;G1、G3、G5、G6为多核丝核菌,初步推断为兰科丝核菌类的念珠菌根菌(Moniliopsis)。

[Abstract]
29 strains of endophytic fungi were isolated from A.roxburghii, and 7 strains belonged to Rhizoctnia sp. Basing on the culture modality of Rhizoctnia sp, tests of anastomosis group and analysis of 5.8S rDNA-ITS, J1, F1, F7 were found to belong to binucleate Rhizoctonia AG-P. F1and F7 were in the same sub-group, and J1 was in a single sub-group. G1, G3, G5 and G6 were pilot concluded belonging to Moniliopsis of multinucleate Rhizoctonia from orchid.
