The paper presents the effect of spindle and irregular palmette crown shapes as well as the influence of intensity of pruning on cropping and fruit quality of apple cvs Idared and Gloster. At spindle crown shape spacing was 4 x 1.8 m with M 26 rootstock. Under the irregular palmette with angled branches the spacing was 4 x 4 m and the rootstock was MM 106. It has been established that the yield height presented in kg/tree changes considerably by cultivar and applied crown shape. Cv Gloster grown under the spindle system gave substantially higher yield per hectare than under irregular palmette. No such regularily may be observed in cv Idared. Yield height, both in kg/tree and t/ha, was not greatly influenced by different pruning intensities. In both cultivars double pruning had positive effect on increase of blush covered fruit area. Fruits of cv Gloster were also more coloured compared to the fruits of cv Idared. Crown shape had no influence in fruit colouring. Intensity of blush was not markedly changed by the evaluated factors. Different pruning treatments and crown shapes did not exhibit considerable influence on soluble solids content and total acids content.
