GROWTH OF MYCORRHIZAL FUNGI IN DIXENIC CULTURES WITH BACTERIA IN MEDIA OF DIFFERENT COMPOSITION

Studies were carried out on the effect of bacteria: Arthrobacter globi formis, Bacillus subtilis and Pseudomonas fluorescens on biomass produ ction by three important ectomycorrhizal fungi: Laccaria laccata, Hebe loma crustuliniforme and Rhizopogon vinicolor in media of different co mposition. It was shown that bacteria stimulated, inhibited or did not affect significantly the biomass production by mycorrhizal fungi. 3-f actor ANOVA have shown that although effect of bacteria was statistica lly significant (p less-than-or-equal-to 0.05), composition of medium and its pH affected mycelial growth stronger than bacteria.
