Effects of bulb storage temperature on flower-bud formation and dormancy breaking were investigated in three hybrid lily cultivars, ‘Morino-otome’, ‘Morino-sei’, and ‘Morino-roman’, developed by crossing Lilium × formolongi with L. rubellum. When the bulbs of these cultivars were stored at temperatures of 5~21°C for 8 weeks, flower-buds formed in their bulbs. The optimal temperature for flower-bud formation in these cultivars was about 13°C, which was lower than that of L. rubellum. Dormancy was broken in these cultivars by temperatures of 5~13°C for 8 weeks, which was shorter than that of L. rubellum.
