Abstract
Pruning studies were conducted in Concord vineyards over a five year period to determine the effects of dormant season pruning date and cane length on cold hardiness and water content of buds and canes as assessed by field mortality and artificial freezing test. In spring, fall-pruned vines showed more field bud kill than unpruned controls, but results of artificial freezing tests were inconsistent. Although gross water content of primary buds was inversely related to cold hardiness in a general way, specific hardiness differences could not be correlated with changes in water content.
