Abstract
The interrelation of components of vine productivity and the cold resistance of primary buds of Concord (Vitis labruscana Bailey) grapevines was studied over several years so that initial and equilibrium response data were collected. In the course of study, vine productivity was manipulated by defoliation at véraison, varying pruning severity, and flower cluster thinning. The effect of these treatments on components of production and cold resistance of primary buds was measured.
Both initial and equilibrium responses to the treatment combinations were observed. Defoliation at véraison had the greatest negative effect on both yield and cold resistance. Of the various yield components measured those treatments which favored vine size, yield, fruitfulness, and soluble solids also favored the cold resistance of primary buds.
