Abstract : Postharvest changes in mango cv. Nam Dok Mai fruits from different parts of the tree were followed after collection at 3 stages of maturity (14, 15 or 16 weeks after full bloom). The fruits were ripened at room temperature (31.5°C) and 58.5% RH. Regardless of maturity stage at harvest there were no statistically significant differences in the quality of ripened fruits between the upper and lower parts of the tree. However, general quality appeared slightly better in the fruits from the upper part of the canopy; these fruits had a deeper-yellow pulp, higher contents of TSS and reducing sugars and a higher TSS:titratable acids ratio but lower moisture content, ascorbic acid, flesh firmness, titratable acidity and total non-structural carbohydrates than fruits from the lower part of the canopy.
