Abstract:
This study deals with colony expansion characteristics, biomass increment and Na accumulation in mycelia of three ectomycorrhizal fungi ( Boletus edulis, Xerocomus chrysenteron and Gomphidius viscidus ) under treatment of Na2SO4 and NaCl. The experimental results showed that no impact was observed from Na2SO4 and NaCl treatments on the growth mode of the mycelia, but the biomass increment of X. chrysenteron and G. viscidus was significantly restrained under 0.1 mol/L Nacl. Under the treatment of Na2SO4, biomass increment of X. chrysenteron is significantly higher than the control, but the biomass of G. viscidus is lower than that of the control, and no significant impact was measured on growth of B. edulis under both treatments of Na2 SO4 and NaCl. The experiment also indicated that Na accumulation in mycelia varied significantly among the three tested strains, highest Na accumulation was measured in X. chrysenteron under treatment of NaCl, while under the treatment of Na2SO4 , accumulation of Na in B. edulis is much higher than the other two strains.
