Abstract
Phalaenopsis plants flowered 3 1/2 months after passing from a 24/22 d egrees C day/night to a 22/17 degrees C regime without changing the ph otoperiod (12:12). The new thermoperiodic treatment induced rapid IAA fluctuations (with a significant peaking between day 2 and day 5), and about the same fluctuation for putrescine. Since flowering occurred m uch later and because quite similar results were observed during plant cold acclimation, the relationships of the biochemical changes regist ered with flowering induction were questioned.
