The impact of the pruning system on the sweet cherry tree growth and fructification

Abstract

The purpose of the research was to evaluate the impact of the time of the pruning of the sweet cherry trees of Kordia, Regina, Stella, Ferrovia and Skeena varieties, grafted on the Maxima 14 rootstock, on the yield and quality of sweet cherries (Prunus avium L.). The orchard was laid out with 3 m between trees in the row, and 5 m between rows. The canopy of the trees was small and of a naturally improved shape. The maintenance and thinning pruning of the sweet cherry trees were done during both the growing season and the dormant period.
