Sažetak
The growth of sweet cherry (Prunus avium L.) trees grown in heavy soil was studied for eight years (1997-2004) after planting. The experiment included 'Burlat', 'Hudson', 'Karina', 'Kordia', 'Margit', 'Oktavia', 'Regina', 'Sam', 'Schneiders Spate Knorpelkirsche' and 'Sunburst'. The trees were grafted on Weiroot 158, planted at a spacing of 5x3 m and trained as free-spindle trees. After 8 seasons, tree growth and mortality, cumulative yields, and yield efficiencies were differed by cultivar. 'Burlat' was the most vigorous, while the vigor of 'Karina' and 'Kordia' was medium and that for 'Regina' was low. Cumulative yield was highest for 'Oktavia' (55.6 kg/tree), followed by 'Burlat' (52.4 kg/tree) and 'Karina' (50.0 kg/tree). Significantly low cumulative yields were obtained from 'Schneiders S.P.' (43.9 kg/tree), 'Regina' (40.1 kg/tree), 'Margit' (39.8 kg/tree) and 'Sam' (38.3 kg/tree). 'Hudson' had the lowest cumulative yield (31.8 kg/tree). The highest yield efficiency was with 'Regina' (1.16 kg/cm2 TCSA) and the lowest was for 'Hudson' (0.61 kg/cm2 TCSA) and 'Burlat' (0.64 kg/cm2 TCSA). The tree mortality was highest for 'Sunburst', medium for 'Burlat', 'Kordia' and 'Schneiders S.P.', and low for 'Oktavia' ; no trees of other cultivars died during the experiment.
