Abstract
The paper deals with interactions of some microfungal strains isolated from rhizosphere soils from three different sites with ectomycorrhizal fungus Cantharellus tropicalis mycelium grown in vitro on agar plates. The rhizospheric fungi were isolated from 3 different sites of bamboo forest and grown against Cantharellus. The cross inoculation method showed that C. tropicalis was highly active against some fungi, thus resulting in different types and strength of interactions. Overgrowth was the most common interaction (45%), followed by inhibition at distance (29%), intermingling (17%) and contact inhibition (13%). The competitive strength of the ectomycorrhizal fungus was high and only affected by some fast growing sterile mycelia, an unidentified fungus and Trichoderma viride.
Key words: Cantharellus, ectomycorrhiza, mycorrhizal systems, biological control, soil micro fungi.
