Evaluation of growth and productivity of some European plum cultivars
Growth and productivity characteristics (initial and final fruit set, yield tree‑1, trunk cross-sectional area, yield efficiency and fruit weight) were studied in ten cultivars of European plum in the Belgrade area during the period of three years (2013-2015). The tested cultivars originate from Serbian and German breeding programs. The cultivar Stanley was taken as a control for comparison. Initial fruit set ranged from 35.7 to 69.9%, and final fruit set from 17.7 to 49.7%. Compared to control, final fruit set was significantly higher in cultivars Čačanska Rodna and Katinka, while it was lower in cultivars Čačanska Rana and Boranka. The average yield tree‑1 was the lowest in the cultivar Boranka (7.8 kg) and the highest in the cultivar Čačanska Najbolja (23.6 kg). Significantly lower yield compared to control was obtained in cultivars Boranka and Čačanska Rana. The lowest vigor was recorded in Čačanska Rodna, and the highest in the cultivar Jojo. The average fruit weight ranged from 22.1 g in the cultivar Katinka to 52.8 g in the cultivar Čačanska Rana. Compared to control, fruit weight was significantly higher in Čačanska Rana, Čačanska Najbolja and Čačanska Lepotica, and lower in Katinka. Yield was correlated with final fruit set (r=0.47*). Fruit weight was in negative correlation with initial and final fruit set (r=-0.75**; r=-0.69**).
