The aim of the study, conducted during 2005-2007 at the Experimental Station in Samotwor, near Wroc law, was to estimate the growth of peach trees on Pumiselect® rootstock, depending on the age of planting material and density of planting, in comparison to peaches grafted on seedling rootstocks. In the spring of 2005 one-year-old and two-year-old peach trees cvs 'Inka' and 'Redhaven' on Pumiselect® rootstock were planted at a spacing of 4 x 1 m and 4 x 1.5 m. As a control, maiden trees on Persica mandshurica rootstock were planted 4 x 1 m and 4 x 3 m apart. The trees planted at 4 x 3 m were trained as a vase canopy, without leader. The trees planted at spacing 4 x 1-1.5 m were trained as an axial canopy with central leader. The trees on Pumiselect® rootstock planted at the higher density (4x1m apart) were characterized by 17-37% weaker growth, expressed by TCSA, in comparison with the trees on seedling rootstock planted at the same spacing and by 49 -63% in comparison with the trees on generative rootstock planted at the spacing of4 x 3 m.
