【摘要】 通过测定3种外生菌根真菌-美味牛肝菌(Boletus edulis)、红绒盖牛肝(Xerocomuschrysenteron)和铆钉菇(Gomphidius viscidus)在Na2SO4和NaCl处理下的菌斑增长特性、生物量积累和菌丝中钠元素积累量显示,2种盐都没有影响菌丝的生长模式。但在0.1mol/L浓度下,NaCl显著抑制了X.chrysenteron和G.viscidus的干重增长;在Na2SO4处理下,X.chrysenteron生物增长量比对照显著增加,G.viscidus则降低,而2种盐处理对B.edulis的生物量积累没有显著影响。3供试菌种在2种盐处理下,其对钠元素的吸收和积累量差异显著。.NaCl处理下,X.chrysenteron菌丝积累的钠量最多,而在Na2SO4条件下,B.edulis菌丝中钠积累量显著高于其他2菌种。更多还原

【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.更多还原
