Growth and reproductive behavior of nine sweet cherry cultivars grafted on two vegetative rootstocks
To determine the influence of rootstock-cultivars combinations on growth and reproductive behavior of sweet cherry trees an experiment was conducted in the Institute of Agriculture, Kyustendil, Bulgaria. A plantation with the cultivars 'Regina', 'Katalin', 'Summit', 'Sunburst', 'Koralize', 'Naprumi', 'Merchant', 'Kordia' and 'Hedelfinger' was established in 2003. The trees are grafted on Gisela 5, 'Kordia' and 'Hedelfinger' also on Maxma 14. Planting distances are 4/2.5 m. Growth and reproductive behaviors of the sweet cherry trees are more pronounced on Maxma 14 than on Gisela 5. The most large-fruited cultivar is 'Summit', where the average weight during the study was 9.2 g, and in some years reached up to 10.4 g. 'Katalin' grafted on Gisela 5 has the highest net income (519.13 lv da-1), which together with other indicators determined it was the economically most effective combination for the conditions of the experiment.
