Sammendrag

A system for winter greenhouse production of strawberries was developed in Norway. Plants of the June-bearing cultivar `Korona" were artificially induced to flower with short-day (SD) treatments. Plants were induced to flower three times: in July, in September and in December, and were harvested from November to June. Three-week old strawberry plants exposed to fourteen 12-hour SD cycles in May, were compared to non-treated plants (control) and large, cold-stored tray-plants. Photoperiod preconditioned plants produced significantly more branch crowns than control plants, but less than cold-stored tray-plants. Preconditioned plants produced more fruits than control plants, but the difference was not significant. Cold stored tray-plants had the highest total yield. Large multiple-crown, cold-stored tray-plants are of variable quality and expensive in Norway. Photoperiodic preconditioning is potentially useful for increasing strawberry productivity and therefore the profitability of a winter greenhouse production system.
