摘要

This study was conducted during 2019/2020 on sweet cherry trees (Prunus Avium L.) (Bing and Hardy Giant) cultivar planted at Sergaya-Al_Zabadani area of Rural Dam ascus, to reduce fruit drop of sweet cherry. The experiment included 4 foliar applications: T1: control, T2: GA_(3) (100 ppm), T3: NAA (20 ppm), T4: (100 ppm GA_(3) + 20 ppm NAA). Fruit set and fruit drop pe rcentage, fruiting factor, and yield were recorded. The results showed that treatment with (100 ppm GA_(3) + 20 ppm NAA) recorded higher fruit set percentage (73.81% and 75.62%), and fruiting factor (48.38% and 50.04%) respectively ; In addition to fruit yield (40.19 and 41.21 kg/tree) for both cultivars, co mpared to the control (9.13, 6.60 kg/tree). Therefore, it can be concluded that GA_(3) + NAA treatment reduced Sweet cherry fruit drop better than other treatments, where fruit drop percentage didn’t exceed (63.11% and 62.01%) in both cu ltivars (Bing and Hardy Giant) respectively, compared to the control (80.92% and 80.64%).
