The effect of different types of rootstock on the quality of maiden trees of sweet cherry (Prunus avium L.) cv. ‘Regina’

Abstract

Over the period 2006–2009 in Lublin, a study was conducted to determine the effect of five types of rootstock: ‘Colt’, ‘F12/1’, sweet cherry (Prunus avium L.), ‘GiSelA 5’ and ‘Piast’ mahaleb cherry (Prunus mahaleb L.), on the growth and quality of maiden sweet cherry trees cv. ‘Regina’ in a commercial nursery. Based on the three-year average, rootstocks were shown to have a significant effect on the investigated quality characteristics of maiden sweet cherry trees. Trees budded on ‘Colt’ vegetative rootstock were characterized by strongest growth and best quality. In each year, they were thicker, higher and better branched than sweet cherries on the rootstock. Under the tested conditions, ‘GiSelA 5’ dwarf rootstock significantly reduced the growth and quality of budded sweet cherry trees in the nursery. During the period 2007–2009, no physiological incompatibility symptoms were observed ‘Regina’ sweet cherry cv. and ‘Piast’ seedling rootstocks. The growth of trees budded on ‘Piast’ mahaleb cherry was poorer than on ‘Colt’ clonal rootstock, but it was stronger than on ‘F12/1’ and Prunus avium L. rootstocks.
