The effect of night temperatures on the yield and quality of the rose, cultivars 'Baccara', 'Sonia' and 'Belinda', was studied during the winters of 1974/75 and 1975/76. Lower night temperature decreased the number of saleable flowers, reduced flower stem length, and increased 'Baccara' flower malformation. Sacrificing autumn yield (October-November) increased the number of mid-winter flowers and their stem length while significantly decreasing 'Baccara' flower malformation. The favorable response to sacrificing early yield is attributed to an enhanced rate of lateral bud breaking, as well as to a prolonged accumulation of summer metabolites and a more satisfactory balance of growth substances which reduce the incidence of flower malformation. © 1978.
