Аннотация: Mycorrhiza-forming species mainly of the genera Amanita, Boletus and others and some litter-decomposing species were employed. For ecological characterisation of the experimental material, most of these species were tested for the ability to produce the extra-cellular enzymes, cellulase, pectinase, proteinase and laccase. The result from experimental series having raw humus as the only nitrogen source indicated that the myccorhiza-forming fungi, like most of the litter-decomposers, could utilise to a very limited extent or not at all the nitrogen bound in the humus. The inoculation of cultures of pine seedlings on gamma-sterilised, N15- labelled raw humus with pure culture
suspensions of different mycorrhiza-formers and litter-decomposers influenced to varying degrees both the supply of assimilable nitrogen and plant development.
