The experiment was carried out to clarify the effect of red, orange and blue fluorescent lights and darkness during the scaling on the growth behaviour of scale bulblets in the Easter lily. Easter lily 'Hinomoto' was scaled at 25, 15 and 10℃ constant temperatures in darkness or in continuous fluorescent lights (0.015 gcal/cm^2・min. at the upper part of scales which was exposed to the air) in a phytotron from Nov. 4, 1972 through April 3, 1973. There were no differences in the bulblet initiation, bulblet growth and death of mother scales among lights at 25 and 15℃. There was a tendency at any temperatures that rooting of scale bulblets occurred more rapidly in red light than in blue or orange lights and in darkness. At 10℃, the bulblet initiation and rooting occurred more quickly in lights than in darkness. They were most rapid in red light. No scaly leaf was observed in any plots at 25℃. At 15℃ there were only 2 cases of scaly leaf emergence in red light. At 10℃ scaly leaves emerged most quickly in red light and they were followed by those in blue light and in orange one. In darkness, however, they did not emerge by the end of experiment.
