Abstract: At- a continuous high temperature of 28℃, adult plants of Phalaenopsis amabilis continued to form foliage leaves at the shoot apex, but did not produce flower-stalks. In order to bring the plants into reproductive growth, low temperatures below 25℃ were required daily more than 12 hours. After exposure to the low temperature for 6-8 weeks, the plants emerged flower-stalks mainly from the axils of the 3rd and/or 4th nodes below the uppermost leaf. Some of the growing flower-stalks shorter than 5cm, on which the primordia of the 1st and 2nd florets had been initiating, became abortive, when the high temperature was subsequently applied. While, the high temperature applied after the stalks reached to 10cm, where the 1st and 2nd florets began to differentiate petals, was not harmful to the further development, but rather accelerated the growth of the stalks.
