Sulfur nutrition involves in the stress tolerance in forage rapes
The objective of this study was to investigate the effect of sulfur nutrition on antioxidative system under salt stress or Fe deficiency under with-and without sulfur nutrient condition.Salt stress and Fe deficiency induced oxidative stresses lead to accumulation of O2-and H2O2.These indicants of oxidative stress were significantly alleviated by sulfur supply.Under salt stress, the activity of antioxidative enzymes such as superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) was significantly decreased compared to control, while these enzyme activities were much higher in presence of sulfur (S) than in absence of S.Fe deficiency significantly induced antioxidant enzymes activity but their levels were less significant under S present condition.The present results indicated that sulfur nutrition has significant role in ameliorating the damage in oxidative stress by salt stress or Fe deficiency.
