Estimation concerning the growth of sweet cherry tres on four rootstocks in nursery

Kordia and Regina sweet cherry tree cultivars were grafted on Prunus avium, Prunus mahaleb, F 12/1 and Colt rootstocks, by using a T budding method. There was no incompatibility between cultivars and rootstocks in a nursery. According to the diameter of sweet cherry scion, the greatest growth was registered in F 12/1 rootstock and the lowest, in Prunus mahaleb. The cultivars grafted on Colt rootstock had more lateral shoots than the other rootstocks. Sweet cherry tree cultivars grafted on F 12/1 and Colt rootstocks were more compatible than Prunus avium and Prunus mahaleb. The cultivar has influenced only the height and the average length of lateral shoots of sweet cherry scions
