The effect of low temperatures on the keepability of bulbflowers.

Tulip flowers (cv. Apeldoorn) were harvested at the recommended maturity stage, recut, wrapped in paper in bunches of 10 and placed in water at 2 deg C for 1 h. FW was determined. The flowers were then stored in water, dry-stored wrapped in paper or dry-stored with each flower lying separate on a shelf at 2 deg for 1, 2, 3, 4 or 5 days. After storage the stems were recut, and bunches were wrapped in paper and placed in water at 2 deg for 1 h. FW was again determined. Quality during vase life was determined at 20 deg , 60-80% RH and irradiance at 7.5 W/m2 during a 12 h photoperiod. Flowers stored in water showed an increase in FW after all storage periods. Dry-stored flowers wrapped in paper showed an increase in FW after 1, 2 and 3 days' storage but showed a decrease in FW after 4 and 5 days' storage. Dry-stored unwrapped flowers showed an increase in FW after 1 day of storage but thereafter showed a decrease. A decrease in FW corresponded with a visual decline in flower quality, shown as deformed flowers, with poor colour and paper-like petals.
