Résumé

Cut rose cv. Bridal Pink flowers, precooled for 2 h, were subjected to simulated transport for 0, 24, 48 or 72 h at 20 or 5 °C. After simulated transport, vase life was determined, which was 9.2 days for control (no transport) flowers. When flowers were transported dry in carton boxes for more than 24 h at 20 °C or for more than 48 h at 5 °C, they displayed bent necks during transport and some buds failed to open, shortening vase life. When flowers were transported wet with their stem bases in deionised water, they maintained their fresh weight, especially at 5 °C, thus prolonging vase life. Substituting 0.3 mM 8-hydroxyquinoline sulphate and 0.1 M fructose for deionised water during the 72-h transport period at 5 °C prolonged the vase life of cut roses by more than 2 times that of dry-transported ones.
