Abstract
Removal of frost-injured shoots by stripping out or cutting them off failed to produce significant increases in yield of fruit over vines receiving no treatment. The lack of significant response was shown for one spur-pruned variety and two cane-pruned varieties of wine grapes.
The per cent total carbohydrate, calculated on a dry-weight basis, of the shoots, spur bark, and spur wood in late April failed to show significantly lower levels when correlated with the length of shoot development.
Cluster weights but not berry weights were heavier for clusters produced on shoots growing from primary buds than for clusters and berries on shoots growing from secondary or tertiary buds. Maturity began at an earlier date and was higher at time of harvest in clusters from primary buds not injured by frost.
