摘要/Abstract

摘要： 为了了解大兴安岭北部地区兴安杜鹃（Rhododendron dauricum L.）的菌根真菌多样性特征。采用形态学和r DNA ITS序列分析相结合的方法。结果表明从兴安杜鹃根样中分离得到的真菌分属于7个属：Phialocephala、粒毛盘菌属（Lachnum）、膜盘菌属（Hymenoscyphus）、Meliniomyces、丝核菌属（Rhizoctonia）、被孢霉属（Mortierella）和软盘菌属（Mollisia）。其中Phialocephala、粒毛盘菌属（Lachnum）和膜盘菌属（Hymenoscyphus）为兴安杜鹃菌根真菌优势类群,在分离的菌株中所占比率超过了20%。研究表明与兴安杜鹃根共生的真菌类群较丰富。

Abstract: The diversity of mycorrhizal fungi isolated from Rhododendron dauricum L.in the northern region of Great Khingan mountains was examined for the first time. In this study, morphology and r DNA ITS sequence analysis were used to identify the fungal communities. The results showed that seven groups of fungi were isolated from root samples of Rhododendron dauricum L.,they were Phialocephala; Lachnum; Hymenoscyphus; Meliniomyces; Rhizoctonia; Mortierella and Mollisia.Phialocephala, Lachnum and Hymenoscyphus were the dominant groups,whose proportion of the strains is more than 20%.This study indicated that the diversity of fungi associated with Rhododendron dauricum were abundant.
