Pot-cultured Cymbidium hybridum was taken as experimental material,the mycorrhizal microstructure was observed with the root tissue slices,the endophytic fungi was isolated and cultivated by the tissue isolation method,and the fungi was identified through the microscopic observation of the mycelium and spore morphology.To lay a foundation in clarification of the interaction mechanism of Cymbidium hybridumand its mycorrhizal fungi.The results showed that the cortex cells were the main colonization position o...
