Effects of CdCl₂, NaCl and H₂O₂ treatments on SOD (a), CAT (b) and GR (c) activities in mycelia of Hypsizygus marmoreus. The mycelia were cultured on PDB medium for 10 days, followed by 24 h incubation with CdCl₂, NaCl and H₂O₂. Data are mean ± SE from three independent experiments. Bars with different letters are significantly different at P < 0.05 according to Duncan’s multiple range test
