  • z Bud pruning treatments: control, no treatment; lateral bud pruning, lateral buds in terminal bud cluster were removed leaving the terminal bud intact; terminal bud cluster removal, the terminal 2.5 cm of the terminal bud cluster was removed and the upper most intercluster bud was taped to re-establish a central leader.
