Abstract : The effects of 2,6-dichloroisonicotinic acid (INA) on the quality of harvested mango (cv. Zihua) fruits were studied. Fruits dipped in INA solution (0, 20 or 100 mg INA/litre) under vacuum infiltration for 2 minutes at a low pressure (0.08 MPa) and for additional 10 minutes at air pressure were air-dried and stored at 13°C and 85-95% relative humidity. Fruits treated with 20 and 100 mg INA/litre maintained greater firmness and ascorbic acid content than the control fruits. INA delayed the change in fruit peel colour. Decay incidence and severity of fruits were reduced by INA. However, INA had slight effects on total soluble solids content and titratable acidity during storage. The results suggested that INA has beneficial effect on improving the postharvest quality and delaying ripening of mango fruits during storage.
