摘　　要：为探明马缨杜鹃菌根真菌的种类,采用rDNA-ITS-PCR分子生物学方法对分离的马缨杜鹃菌根真菌进行鉴定。结果表明:从马缨杜鹃菌根共分离出6种与杜鹃花类菌根真菌Phialocephala sp(CK007137)、Oidiodendronsp(HM208742.1)、Oidiodendronsp.shylhs04(AY268186.1)、2个不同的Epacris root associated fungus类菌株和fungal sp.R38亲缘关系十分密切的真菌。其中,前5种真菌与其他ERM植物的菌根真菌同源或近缘,fungal sp.R38是ERM植物菌根真菌的新类型。Abstract： To explore the species of mycorrhizal fungi of R. delavayi, and provide technical reserves for cultivation and application of R. delavayi, the molecular biological method rDNA-ITS-PCR was employed to identify the isolated mycorrhizal fungi of R. delavayi. Results ： six kinds of mycorrhizal fungiclosely related to ERM were isolated, which were the relatives of ERM and fungal sp. R38 which was a new type of ERM respectively.
