Sažetak
Peach is one of the most important fruit species for human consumption. In the peach cultivation many pomotechnical treatments are conducted and some of the most interesting are summer pruning and fruit thinning. By implementation of mentioned pomotechnical treatments higher fruit quality can be achieved which is nowadays very important for the market fruit value. In this research the infl uence of summer pruning and fruit thinning in diff erent combinations on the pomological characteristics and physico-chemical properties of peach fruit cultivar ‘Royal Gem’ was studied. Implemented pomotechnical treatments diff erently aff ected the studied properties. Th e highest yield was determined in control (7.23 kg tree-1) while the lowest (4.38 kg tree-1) in treatment 2 (fruit thinning without summer pruning). Fruit thinning and summer pruning signifi cantly infl uenced on the increase of average fruit weight, fruit fi rmness and fruit diameter. Th e lowest fruit weight (75.74 g) was determined in control while the highest fruit weight (92.93 g) was determined in treatment 3 (summer pruning without fruit thinning). Th e highest fruit diameter (57.69 mm) was also determined in treatment 3 while the lowest in control (52.59 mm). Th e highest fruit fi rmness (4.14 kg/cm2) was in treatment 1. For chemical quality properties no signifi cant diff erences have been determined due to the implemented pomotechnical treatments. Th e pomotechnical treatments conducted in this research showed to be eff ective for improving the fruit quality while the best results were achieved by treatment of fruit thinning.
