| Abstract:
Growth and cropping of plum trees originated from in vitro (TC trees) and trees grafted on Wangenheim Prune rootstock of seven cultivars - ‘Seneca’, ‘Čačanska najbolja’, ‘Čačanska Rodna’, ‘Stanley’, ‘Bluefre’, ‘Valor’, ‘Oneida’ were compared. The orchard was established in the spring, in 1995. The trees started to fruit in the third year after planting. In 1997-2000 the following characters were compared: yield, mass of 100 fruit, trunk cross-section area (TCSA) and two indexes of productivity. In the first and the second year of cropping the higher fruit yield was obtained in the trees grafted on Wangenheim Prune rootstock. In the third and the fourth year the higher yield was obtained in the TC trees. Global yield of four year cropping did not differ statistically at the TC trees and the trees grafted on the rootstock. Growth of TC trees was greater than the grafted trees was. The productivity indexes (kg·cm -2 and kg·m -3) were greater at the trees grafted on Wangenheim Prune rootstock. A susceptibility to plum pox virus was similar for both types of tree production method. | |
