Abstract
By the method of liquid culture, this paper studied the effects of different P and Pb doses on the biomass production of three strains of ectomycorrhizal fungi, and the P and Pb concentrations in their mycelium. The results showed that under the application of P and Pb, the biomass production of strains ZC1 and ZC2, collected from mining area was significantly higher than that of strain GV collected from non-polluted site. At low P level (0.16 mmol x L(-1)), the growth of these three ectomycorrhizal fungi was inhibited by the increasing dose of Pb; while at higher P levels (0.81and 2.42 mmol x L(-1)), increasing dose of Pb inhibited the growth of GV significantly, but had little effects on ZC1 and ZC2. In all treatments, the Pb concentration in GV mycelia was significantly higher than that in the mycelia of ZC1 and ZC2. Under the same dose of Pb, the P concentration in GV mycelia was higher at low P level, but lower at higher P levels than that in ZC1 and ZC2 mycelia. The increase of Pb dose decreased the P concentration in ZC1 and ZC2, mycelia, but had little effect on that in GV mycelia. In comparing with GV, ZC1 and ZC2 had the characteristics of fast growth and low Pb and high P accumulation in their mycelia, indicating that the strains of ecomycorrhizal fungi collected from polluted area had a higher tolerance to environmental stress.
