Abstract This study was carried out during two successive seasons of 2011/2012 and 2012/2013 on 5 years old {u2018}Florda Prince{u2019} peach trees budded on Nemagard rootstock. The trees were grown in sandy soil at private orchard, in Regwa district at Giza governorate, Egypt. Four thinning pruning levels were applied on the 1st November by leaving 70, 85 and 100 one-year-old shoots/tree beside control trees (un-pollarded trees), with or without three heading back cut level treatments (on the same shoots) by removing 25, 50 and 75% from the terminal shoot length. Concerning the effect of thinning pruning levels applications, 70 shoots/tree gave the highest significant leaf to fruit ratio and both fruit physical and chemical characteristics followed by 85& 100 shoots/tree then control trees in both seasons, respectively. In addition, heading back pruning level treatment 75% gave the best leaf to fruit ratio, fruit physical and chemical characters in both seasons. Moreover, the interaction between thinning applications and heading back treatments indicated that 70 shoots/tree + 75% heading back treatment increased leaf to fruit ratio value (35.63:1 & 35.48:1) and fruit quality in both seasons |
