In the experiment, carried out between 2005-2007, the influence of the application of two rootstocks and mycorrhizal vaccine on the growth of maiden trees and the trees of Woodii cultivar in the third year after planting them into the ground was compared. A higher percentage of maiden trees was obtained on Prunus tomentosa rootstock when mycorrhizal vaccine was applied as well. The applied rootstocks did not differ the growth of maiden trees in a nursery. Also the use of mycorrhizal vaccine did not cause any significantly stronger growth of maiden trees on both rootstocks, what is more they even reduced the sum of the lengths of lateral shoots. The reaction of rootstocks was differentiated. The considered rootstocks, however, influenced all the parameters of growth of trees in the third year after planting. Stronger growth of Woodii cultivar trees was observed on the Prunus cerasifera rootstock compared with those growing on Prunus tomentosa. However, the trees growing on the Prunus cerasifera rootstock bloomed poorer than those on Prunus tomentosa. Application of mycorrhizal vaccine increased the thickness of the tree trunk and the diameter of crowns of Woodii cultivar trees, but it did not influence their flowering and fruiting
