The endogenous content of free and bound gibberellins (GA) in leaves and buds of Queen of Vineyard grapevines was determined. Lateral buds on shoots from vigorous vines had about double the free GA activity of buds from less vigorous vines. No difference in the activity of bound GA was found. The GA content in the leaves of Queen of Vineyard was uniform, regardless of the vigor of the plants. The relation between vigor, GA content and bud necrosis in Queen of Vineyard vines is discussed and a causal dependence is suggested.Downloads
