The influence of Hypholoma fasciculare and Phlebiopsis gigantea on the growth of Heterobasidion annosum in vitro

The influence of two saprotrophes — isolates of Hypholoma fasciculare and Phlebiopsis gigantea on the growth of thirty three root pathogen strains — Heterobasidion annosum was analysed. Two methods were used. The different reaction in paired cultures among saprotrophe and pathogen isolates suggest, that one isolate of H. annosum is not enough to study the interaction between this pathogen and saprophytes in vitro irrespective of the method used
