Growth of mycorrhizal fungi of pine (Pinus sylvestris L.) in associative cultures with Actinomycetes at different pH values

Abstract

The effect of 5 actinomycete strains on growth of four mycorrhizal fungi of pine at different pH values was tested in laboratory media. Both inhibition and stimulation of growth was distinctly dependent upon the pH of the medium. In general the actinomycetes introduced to 7-days old fungal cultures more often stimulated than inhibited the fungi. This was not observed when the media were inoculated with both organisms simultaneously.
