Cultivar and Harvest Location Influence Fruit Softening and Antioxidative Activities of Peach during Ripening

Abstract Fruit softening and quality management is very important to reduce postharvest losses in peach. Present study was conducted to observe the effect of harvest location and cultivars on peach fruit softening and quality during ripening at ambient conditions (30±1°C and 60-65% RH). Fruit harvested from Sillanwali exhibited significantly higher ethylene production (24.27 µL C2H4 kg-1 h-1), respiration rate (1.04 mL CO2 kg-1 h-1), ascorbic acid contents (11.11 mg 100 g-1), activities of catalase (CAT; 47.53 U mg protein-1), peroxidase (POD; 32.48 U mg protein-1), endo-polygalacturonase [(endo-PG; 11.61 Delta viscosity (mg protein-1h-1)], exo-polygalacturonase (exo-PG; 138.9 µg gal acid mg protein-1...
