Endomycorrhizal Structure and Solid Medium Selection of Five Orchid Species including Renanthera coccinea Lour
Using five orchid species as experimental materials,Observing the microstructure of mycorrhizal fungi using paraffin sectioning method.And using tissue isolation method to isolate and culture endophytic fun-gi,for selecting the optimal culture medium.The results showed that the root structures of the five orchids are root cover,cortex and stele which all infected with mycorrhizal fungi to varying degrees.Epiphytic orchids are directly infected by cortical cells.Saprophytic orchids are infected by root hairs or cortical cells,and form a mycelium mass.PDA medium is the most suitable medium for isolation and purification of orchid mycorrhizal fungi.
