What is Physiological Responses of Cotton to Stress Moderator Application on Different Planting Date Under Saline Conditions about?

Increased activities of enzymatic and non-enzymatic antioxidants provide a common reaction to environmental stress in most crops. To investigate the effect of foliar application of stress moderators on enzymatic and non-enzymatic antioxidant changes, field experiments were conducted as split-plot design based on a randomized complete block design with three replications in 2017 and 2018. Planting date (early and late) was considered as the main plot, and foliar applications with 50 and 100 mM of Glycine Betaine, 1 and 2 mM of salicylic acid, and 100 and 200 lM of sodium nitroprusside, along with the control treatment, were regarded as the subplot. The results showed that the amounts of chlorophyll pigments and the levels of enzymatic antioxidants (glutathione peroxidase, ascorbate peroxidase, superoxide dismutase, catalase), and proline increased, and H 2 O 2 level decreased with the foliar application of stress moderators. Glycine betaine and sodium nitroprusside had the lowest and highest effects on the enzymatic antioxidant activities, respectively. The analysis of the main components revealed that in the early and delay planting date, the characteristics of enzymatic antioxidan
