Abstract – Introduction. Mango fruits grown underhigh-density planting show a progressive decline in crop yield after14–15 years, due to overcrowding of canopies, which suggests regularcanopy management is necessary. Hence, the effects of pruningtreatment on fruit yield and quality of ‘Amrapali’ mango were studiedin India over two consecutive years, 2010 and 2011. Materialsand methods. Mango trees were subjected to pruning(removal of 50 cm of shoot from the apex) in the month of September2009 with unpruned trees serving as control. Fruits were harvested atthe commercial maturity stage and quality parameters were assessedboth in fresh fruits and following ripening at room temperature [(35 ±2) °C and (80 ± 5)% RH)]. Results and discussion. Fruityield of pruned trees was found to decrease during the first yearcompared with the fruit yield of unpruned trees; later on, itincreased during the second year. Pruning resulted in significantlyhigher fruit weight, fruit firmness, total carotenoids, antioxidantcapacity and total phenolic content. Early maturity of fruits wasobserved from unpruned trees with faster color change, higher totalsoluble solids and lower titratable acidity. The fruits harvested frompruned trees showed slower ripening, and lower respiration, ethyleneevolution rate and enzyme activity as compared with fruits fromunpruned trees. Both anthracnose and stem-end rot disease percentagewere reduced in ripe fruits from pruned trees.Conclusion. Pruning treatment appears to be analternative strategy to obtain better yield and quality in denselypopulated old mango orchards.
