Wpływ mechanicznego przerzedzania kwiatów urządzeniem BAUM na plonowanie i jakość owoców czereśni odmiany ‘Summit’

Thinning of flowers or fruitlets is currently one of the most important agrotechnical treatments in the cultivation of some fruit trees. This paper presents the results of the research on the effect of mechanical thinning of flowers on the yield and fruit quality of ‘Summit’sweet cherries. The experiment was carried out in 2018 at the Pomological Orchard of the National Institute of Horticultural Research in Skierniewice. Mechanical thinning of flowers was carried out with a BAUM machine at two rotor speeds: 300 rpm and 420 rpm. Compared with the control, the obtained results showed that mechanical flower thinning at the rotor speed of 420 rpm resulted in the greatest reduction in the fruit yield (21,5%) and the greatest increase in the weight of a single fruit (26,9%).
