Effects of light break on the growth and flowering of Gerbera hybrida Hort, were examined under the soilless culture during the fall to winter season. The midnight light break treatment was conducted for 1 h from 23: 00 to 0: 30. The appearance of lateral shoots was considerably reduced by the light beak and therefore, number of flower stalks and leaves were less than those under the natural photoperiod. The initial flowering under the light break delayed slightly compared to that under the natural photoperiod.
