After the winter pruning took place, the DBT trees were higher than the OC trees. Likewise, the values of the crotch angles (48°) and the number of branches (81 of 100 branches) that showed desired crotch angles (more than 40°) were remarkably higher in the trees trained with the DBT. In contrast, the distance between the upper two branches (25 cm) at the top of the DBT trees was significantly higher. The average length and diameter values of the upper two opposite branches at the top of the trees trained to the OC were higher than those trained with the DBT. Before the winter pruning took place, measurements were taken on the upper two opposite branches. DBT is a modification of the OC, but no heading was undertaken and the new shoot growth arising from the 20 cm at the top of the plant were removed. The OC trees were headed at 80 cm above the ground. In the late spring, two different pruning systems were applied traditional open centre (OC) and de-branched top trees (DBT). The trees were planted 5 × 5 m in a randomised complete block design with four replicates, with ten trees in each replicate. One-year-old 'Florida Prince' cultivar peach trees grafted on a 'Nemaguard' rootstock were planted in the early spring of 2018 at the Centre of Agricultural Research and Experiments, Minia University, located in southwest Egypt.
