The values of H2O2 concentration (a) and MDA content (b) in non-irradiated (0- Gy) and irradiated (50–300 Gy) highland barley seedlings with or without Pb/Cd treatment. Control, Pb, Cd in non-irradiation (0- Gy) and irradiation (50–300 Gy) groups correspond to non-irradiated or irradiated highland barley seedlings without heavy metal treatment, with 500 µM Pb(NO3)2 treatment and 75 µM CdCl2 treatment, respectively. Vertical bars represent the mean ± SD of three independent replications (n = 3). Different letters indicate significant differences among the different doses of gamma irradiation treatments in control, Pb and Cd group at p < 0.05, according to LSD test.
