The postharvest quality of 3 cultivars of Parade miniature potted roses from 3 growers in Denmark was evaluated during winter and summer 1994, using 0, 2 or 4 days of simulated transport (ST). The main causes of reduced postharvest longevity were wilted flowers, infection by Botrytis and an increased number of yellow buds. After 18 days in a simulated postharvest environment there were no differences in the percentage wilted flowers for all plants subject to ST for 0-2 days. The percentage of wilted flowers increased for 2 of the 3 cultivars exposed to 4 days of ST as compared with controls. The degree of wilting was also dependent on the origin of the plants and was less severe in summer than in winter. The number of yellow buds and infection by Botrytis was higher in plants exposed to 4 days of ST, and was more pronounced in winter. It is concluded that if the initial quality of a miniature potted rose is high and stress conditions during transport are controlled, postharvest longevity can be
maximized.
