  1. Significant P values are given in bold. Treatment corresponds to the combination between pruning intensity and epicormic branches treatment (1 = 1/3 pruned tree without epicormic shoots, 2 = 2/3 pruned tree without epicormic shoots, E1 = 1/3 pruned tree with epicormic shoots, E2 = 2/3 pruned tree with epicormic shoots).
