| Abstract | ||||
| Twenty years old trees of "Succary Abiad" mango cv grown in sandy soil at the orchard of the Faculty of Agriculture, Suez Canal University, were subjected to single tipping (removal of apical buds), frequent tipping (removal of apical buds after each flushing), light, mediate and severe pruning (removal of 5, 10 and 15 cm from the apex, respectively) during 2002 / 2003 and 2003 / 2004. The pruning treatments were significantly stimulated emergence of vegetative flushing, while significantly delayed emergence of prolific flushing compared to unpruned trees. Sex ratio (male: perfect flowers) was observed to be lower in flowers of panicles that appeared in mediate pruning than unpruned trees. Mediately pruned trees produced higher leaf area, number of panicles and number of fruits. A significant increment in tree yield was showed from mediate pruning treatment, while severe pruning reduced tree yield. However, the yield was not respond to single or frequent tipping compared to the controls. SSC was significantly increased as pruning severity increased but titratable acid was decreased. So, mediate pruning should be practiced immediately after fruit harvest for early cultivars like Succary Abiad to increase yield and improve fruit quality. | ||||
