摘要：

The effect of evaporative cooling in a compartmentalized greenhouse on the flower production and quality of 4 rose cultivars was investigated during 2 cutting-seasons. Evaporative cooling reduced flower formation of all rose cultivars tested, regardless of their location in the greenhouse. This reduction was ascribed to the decrease in growth rate of rose shoots resulting in fewer flowering-flushes than in the uncooled control plants during the same time period. Flower quality, however, was significantly improved under evaporative-cooling conditions. This was apparent in an increase in weight of the entire flower as well as in unit of flower-stem length. Weight of the flowering-bud was less affected, and was increased during the autumn and spring seasons only. Anthocyanin content of flower petals was increased by evaporative cooling, especially during the summer. © 1979.
