Abstract:
Mango (Mangifera indica L. cv. Nam Dokmai) fruits chilled for 21 d at 4°C were firmer than non-chilled fruits during subsequent ripening at 25°C. The cell wall contents of chilled fruit: contained less water-soluble pectin, more ammonium oxalate-soluble pectin and less alkali-soluble pectin than non-chilled fruits. The increase in ammonium oxalate-soluble pectin was at the expense of the alkali-soluble pectin and correlated with high pectinesterase activity in the fruit from low-temperature storage. Polygalacturonase and β-galactosidase activities were inhibited in chilled fruits. The relationships between delay in loss of firmness, and differences between activity of cell wall enzymes and pectin content of chilled and non-chilled fruits are discussed.
