"This study was carried out to evaluate the effects of interior air temperatures and light levels on qualitative maintenance of potted Cyclamen percicum Mill.. 'Schubert' plants were placed under different interior air temperatures of 10degC, 15 deg C and 20 deg C for 10 weeks under 7001x(=10micromol / m-2 / s-1 PPFD) light intensity by 3-band radiation type day-white fluorescent tubes for 12 hours of daylength. Plants were maintained with better quality when held under the lower temperatures. Plants placed at 10 deg C had the fewest numbers of flowers, but had the longest flowering period and the least number of yellowing leaves. 'Zairai-aka' was placed under different interior light levels of 100, 700 and 20001x(12 hour photoperiod using the same fluorescent tube described above) with a constant temperature of 20 deg C. Plants were maintained with better quality when held under the higher light intensities. The highest number of yellowing leaves and dead flowers occurred and plant quality decreased fastest under the light intensity of 1001x."
