The total activity antioxidant enzymes stayed larger greater under drought than ment. The total activity from the in the antioxidant enzymes stayed below drought than manage handle samples. POD activity increased initially below drought tension but start off decreasing at extreme drought, having said that, elevated soon after rewatering. MDA levels initially declined due to the severity from the extended drought, but then improved slightly immediately after re-watering,Int. J. Mol. Sci. 2021, 22,four ofInt. J. Mol.

MDA levels initially declined as a result of severity of your extended drought, but then elevated slightly after re-watering, and restored under and restored beneath moderate drought. CAT and PPO had been increased with all the prolonged moderate drought. CAT and PPO had been increased with the prolonged drought, even though CAT drought, even though CAT activities were declined following re-watering (Figure two). activities were declined after re-watering (Figure two).
