Superoxide dismutase activity (SOD; U mg⁻¹ protein min⁻¹), ascorbate peroxidase activity (APX; U mg⁻¹ protein min⁻¹), glutathione reductase activity (GR; U mg⁻¹ protein min⁻¹), glutathione peroxidase activity (U mg⁻¹ protein min⁻¹), reduced glutathione content (GSH; nmol g⁻¹ fresh mass), and ascorbate content (AsA; mg g⁻¹ FW) in wheat (Triticum aestivium) exposed to salt stress (100 mM) and supplemented with silver nanoparticles (AgNPs; 300 ppm) at 30 days after sowing (DAS). Data fallowed by the same letter are not significantly different by LSD test at (p ˂ 0.05).
