Abstract
SummaryModified environments enable out-of-season strawberry fruit production, but factors that regulate growth and flowering need to be understood to obtain optimum production. Phytotron and controlled temperature glasshouse studies compared the responses of two shortday (SD, Junebearing) cultivars (Redgauntlet and Torrey) and three dayneutral (DN) cultivars (Aptos, Brighton and Hecker) of strawberry (Fragaria 3 ananassa) to various daylength and temperature regimes. The responses were determined independently for inflorescence initiation and the development of inflorescences and fruit. Daylength (9 or 15.h) and day/night temperature regime (18/13, 21/16 or 30/258C), during inflorescence initiation had major effects on yield parameters in the SD cultivars. Floral initiation was repressed in long days, with poor fruit set and development compared with flowers initiated under short-day conditions. The day-neutral cultivars were less affected by daylength, but each had specific temperature/daylength combina...
