Figure 4. Effects of NaHS on the activities of ROS detoxifying enzymes in the leaves of rice plants with or without Cd stress.

Figure 4

(a) superoxide dismutase (SOD), (b) catalase (CAT), (c) ascorbate peroxidase (APX), (d) monodehydroascorbate reductase (MDHAR), (e) dehydroascorbate reductase (DHAR), (f) glutathione reductase (GR), (g) glutathione peroxidase (GPX) and (h) glutathione S-transferase (GST). Control, H2S, H2S + HT, Cd1, H2S + Cd1, Cd2, H2S + Cd2, and H2S + HT + Cd2 correspond to the group of seedlings exposed to only nutrients, 100 μM NaHS, 100 μM NaHS + 200 μM hypotaurine, 250 μM CdCl2, 100 μM NaHS + 250 μM CdCl2, 500 μM CdCl2, 100 μM NaHS + 500 μM CdCl2 and 100 μM NaHS + 200 μM hypotaurine + 500 μM CdCl2, respectively. Bars represent standard deviation (SD) of the mean (n = 3). Different letters (a–f) indicate significant differences among the treatments at P < 0.05, according to Duncan’s multiple range test.
