云南兰科植物菌根内生真菌种类研究

Study on Taxonomy of Endophytic Fungi Isolated from Orchid Mycorrhizae in Yunnan Province

摘要: 从云南省兰科植物主产区的8个地区11个品种89株兰科植物的营养根上分离获得真菌菌株184个,其中出现频率较高或文献曾报道为兰科内生菌根真菌的有65个.根据菌落形态、菌丝特征、产孢结构、孢子形态及子实体诱导等大致分为18类,分别隶属于丝核菌属、兰科丝核菌类、毛壳菌属、木霉属、镰刀菌属、顶枝孢、束格孢属、团丝核菌属、Trichosporiella sp.、Gliomastix murorum、兰小姑、微囊菌属、Catenularia piceae、丝孢纲的其他属等.

Abstract: 184 representative fungi strains were isolated from 89 orchid plants of 11 varieties from 8 major orchid distribution areas in Yunnan Province. 65 strains among them showed higher infection frequency or had been reported as endophytic mycorrhiza fungi. 18 groups out of the 184 isolated strains were classified according to colonal morphology, hyphal characteristics, fruiting organ, spore morphology and derivation fruiting body, which respectively belonged to Orchidaceous rhizotonias, genera of Rhizoctonia, Chaetomium, Trichoderma, Fusarium, Diplococcoium, Acremonium, Sarcinella, Papulaspora, Trichosporiella, Microascu and other genera of Hyphomycetes, as well as Gliomastix murorum, Mycena, Cafenularia piceae species.
