Activity of the ascorbate-glutathione cycle enzymes in wheat (Triticum aestivum L. var. WH 542) leaves treated with SNP (100 µM) and/or NaHS (200 µM) in the presence (40 °C) or absence (25 °C) of heat stress at 30 days after sowing (DAS). (a) Ascorbate peroxidase (APX) activity. (b) Monodehydroascorbate reductase (MDAR) activity. (c) Dehydroascorbate reductase (DHAR) activity. (d) Glutathione reductase (GR) activity. Data are presented as treatments mean ± SE (n = 4). Data followed by the same letter are not significantly different by LSD test at (p < 0.05). Asc, ascorbate; SNP, sodium nitroprusside; NaHS, sodium hydrosulfide.
