Developmental changes in antioxidant metabolites, enzymes, and pigments in fruit exocarp of four tomato (Lycopersicon esculentum Mill.) genotypes: beta-carotene, high pigment-1, ripening inhibitor, and 'Rutgers'.

Abstract excerpt

In surface cell layers of fleshy fruit, antioxidants must limit photooxidative reactions that generate reactive oxygen species (ROS) in high light. Our objective was to measure changes in the concentrations of antioxidant metabolites and pigments, and the activities of enzymes of the Mehler-peroxidase, ascorbate-glutathione cycle in fruit exocarp tissue under non-stress conditions of the following fruit-specific...
