Effects of temperature and photoperiod on the development of inflorescences were investigated with one-year-old everbearing strawberry (Fragaria x ananassa Duch.) 'Summerberry' plants. When plants were grown at 20/15 °C and 25/20 °C, more inflorescences developed under a 24-hr than under an 8-hr photoperiod. At 30/25 °C, the development of inflorescences ceased under an 8-hr photo-period but the development of axillary inflorescences without a foliage leaf was promoted under a 24-hr photoperiod. The results indicate that 'Summerberry' plants are quantitative long-day plants at 20/15 and 25/20 °C and qualitative long-day plants at 30/25 °C.
