*The different letters on the same column indicate significant differences between treatments, rootstock and crop load separately. The analysis was conducted with all data resulting from 9 trees of “Ligol” and “Auksis” apple trees grafted on M.26, M.9, B.396, P 67, and P 22, with crop-load adjusted to 75, 113, and 150 fruits per tree. The data were processed using analysis of variance (ANOVA), the Turkey (HSD) multiple range test at the confidence level p = 0.05.
