• Bulbs of Lycoris radiata and L. squamigera did not form flower buds when they were moved from outdoors to the glasshouse kept above 20℃ on or before December 20 and on or before February 20, respectively. Among bulbs grown at 15℃ day/12℃ night, 20℃/17℃ and 25℃/25℃ since the middle of September, those of L. radiata at 25℃/25℃ and of L. squamigera at 20℃/17℃ and 25℃/25℃ did not initiate flower buds. These results indicate that L. squamigera requires longer and lower temperature than L. radiata for floral induction. After the cold requirement had been satisfied, an earlier heating caused earlier flower bud development. High temperature above a critical range also caused reduction in bulb size and provoked an untimely emergence of foliage leaves.
