The effect of rootstocks on the efficiency of a nursery of sweet cherry (Prunus avium L.) trees cv. ‘Regina’

Abstract

During the period 2006–2009 in Lublin, a study was conducted to determine the effect of five rootstocks: ‘Colt’, ‘F12/1’, sweet cherry (Prunus avium L.), ‘GiSelA 5’, and ‘Piast’, on bud take in the cultivar ‘Regina’, the quality of budded trees and the efficiency of a sweet cherry tree nursery. The highest percentage of bud take in cherry trees cv. ‘Regina’ and the best efficiency of the sweet cherry tree nursery were obtained for the rootstocks ‘Piast’ and ‘Colt’. In two years during the three-year study period, the rootstock was found to significantly affect the efficiency of the sweet cherry tree nursery. When grafted on the rootstocks ‘Colt’ and ‘Piast’, a significantly higher percentage of trees met the requirements of the Polish Standard PN-R-67010 than on the clonal rootstock ‘GiSelA 5’. Under the tested conditions, the quality of maiden sweet cherry trees cv. ‘Regina’ grafted on the dwarfing rootstock ‘GiSelA 5’ was lowest.
