Activities of key antioxidant enzymes in Solanum lycopersicum and Solanum chilense at 0, 7, 14, and 21 d of salt stress conditions. (A) ascorbate peroxidase activity, (B) catalase activity, (C) superoxide dismutase activity, (D) glutathione reductase activity, (E) dehydroascorbate reductase activity, (F) monodehydroascorbate reductase activity, and (G) guaiacol peroxidase activity. The data are mean of three replicates ± SE. * Bars with distinct letters are significantly different at P ≤ 0.05 applying the DMRT test.
