Effects of H2O2 and O2∙- content in tall fescue leaves after 0.5 mM Spd treatment under heat stress. (A) H2O2 content; (B) O2∙- content. CK was normal temperature of 22°C. H was high temperature where tall fescue leaves were treated at 44°C. S was treated with Spd at normal temperature. HS was treated with Spd at high temperature. Values are given as means ± SE of three independent experiments. Different letters indicate statistical difference significance at P < 0.05 among the treatments by Duncan’s multiple range test.
