Same physiological characteristics of the three ectomycorrhizal fungi from Suillus genus

Abstract

The aim of this paper is to present the results of the study of the same physiological characteristics of the three species of ectomycorrhizal fungi from Suillus genus (S. luteus (L. ex Fr.) S.F.Gray, S. bovinus (Fr.) O.Kuntze and S. granulatus (L. ex Fr.) O. Kuntze. S. granulatus is an excellent edible mushroom. S. luteus and S. bovinus are both edible but they are both of an inferior quality. Three different media (Melin-Norkans, MMN, Potate Dextrose Agar, PDA and Malt Extract Agar, MEA) were used for the study of the influence of the type of medium on the rate of growth and morphological shape of mycelium of fungi. The interaction between mycorrhizal fungi was examined in the laboratory conditions by the "mixed cultures". The assessment of the interaction between certain mycorrhizal species and the inhibitions of growth was determined as the ratio between their growth in the mixed culture and the controlling isolate growth on the nutritive media
