(a) Highland barley seeds irradiated with 0, 50, 100, 150, 200, 250 and 300 Gy gamma irradiation; (b) The phenotypic appearance of non-irradiated (0- Gy) and irradiated (50–300 Gy) highland barley seedlings with or without Pb/Cd treatment. Control, Pb, Cd in non-irradiated (0- Gy) and irradiated (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.
