Comparative lipid peroxidation, leaf membrane thermostability, and antioxidant system in four sugarcane genotypes differing in salt tolerance

Role of plant antioxidant systems in salt stress tolerance was studied in four contrasting sugarcane genotypes. Salt stress imposed at various stages of crop growth resulted in an increase in lipid peroxidation and decrease in membrane stability, chlorophyll fluorescence ratio (fv/fm) and chlorophyll and carotenoid contents. The activity of antioxidant enzymes (ascorbate peroixdase, glutathione reductase, and...

Paraquat toxicity and its mode of action in some commonly consumed vegetables in Abeokuta, Nigeria

Paraquat (PQ) is a toxic chemical that is widely used as herbicide in developing countries. This has led to extensive contamination of the environment, foods and food products. Therefore, this study investigated possible occurrence of PQ residues in some commonly consumed vegetables and the mode by which some of them were able to withstand oxidative stress condition associated with PQ toxicity. Levels of PQ residues and...
