The experiment was conducted at the Experimental Station of the University of Life Sciences in Poznań, in the years 2005–2007. The aim of this study was to estimate the influence of a mycorrhizal vaccine on the growth of maiden sweet cherry trees of four cultivars: ‘Burlat’, ‘Regina’, ‘Summit’ and ‘Vanda’. Results of the study proved that the mycorrhizal vaccine did not have significant effect on any of studied parameters of maiden sweet cherry trees growth. Budded cultivars of sweet cherry differentiated the percentage of obtained maiden trees and their branching. The highest percentage of maiden trees was obtained for ‘Regina’ cultivar and the lowest one was observed for ‘Burlat’. Maiden trees of ‘Summit’ cultivar were characterized by much lower susceptibility to creating lateral shoots comparing with other cultivars taken into consideration. Significantly lower value of chlorophyll content was observed in leaves of ‘Summit’ cultivar.
