Weekly pruning treatments between early May and late June with hydrogen cyanamide applications were applied to Cardinal grapes in unvented, unheated vegetable glasshouses. Cyanamide treated vines reached maturity about a month earlier than untreated vines pruned on the same day; the interval between pruning and budburst with cyanamide treatment was 28 - 61 days. Manipulation of pruning time significantly affected the time of ripening in the glasshouse environment. Ripe grapes were produced between 7 November and 19 December by using different pruning times.
