Activity of superoxide dismutase, ascorbate peroxidase, catalase and glutathione reductase of wheat (Triticum aestivum L. var. WH 542) leaves at 30 days after sowing (DAS). Plants were treated with melatonin (100 µM) and/or HT (100 µM) in the presence (40 °C) or absence (25 °C) of heat stress. Data are presented as means ± SE (n = 4). Data followed by the same letter are not significantly different by LSD test at p < 0.05. APX, ascorbate peroxidase; CAT, catalase; GR, glutathione reductase; HS, heat stress; HT; hypotaurine; SOD, superoxide dismutase.
