Abstract:
Vegetative and reproductive characteristics of apple rootstocks ‘М9-Т337’ and ‘Supporter 4 Pi 80’ budded with the cultivars ‘Breaburn Fenbra’, ‘Gala Venus-Fengal’, ‘Golden Delicious clone В’, ‘Pinova’, ‘Red Delicious Hapke’, ‘Red Delicious Redkan’ and ‘Rubinfuji Romf. 811’ were compared in the intensive orchard planted at the density of 2380 trees ha-1 (3.5×1.2 m) in the period 2008-2011. Trees were formed as tall spindle. It was found that, with the exception of the cultivar ‘Pinova’, rootstock ‘Supporter 4 Pi 80’ induced a greater trunk-cross section area, higher trees and greater crown volume to the tested cultivars in comparison with ‘M9-T337’ rootstock. A higher yield per unit area was obtained on ‘Supporter 4 Pi 80’ rootstock compared to ‘M9-T337’ budded with low vigorous cultivar ‘Red Delicious Redkan’, whereas ‘M9-T337’ was superior on this parameter in combination with cultivars ‘Breaburn Fenbra’, ‘Gala Venus-Fengal’, ‘Red Delicious Hapke’ and ‘Rubinfuji Romf. 811’.
