Abstract
These experiments show that a 24-hour photoperiod (continuous light) is far less effective than a 16-hour photoperiod for long-day induction. This is in sharp contrast to the results reported for other long-day plants and may be due to the requirement, in Cestrum nocturnum, for subsequent short-day induction. In fact it has recently been shown for Kalanchoe blossfeldiana, a short-day plant, that preceding long days reduce the effectiveness of short-day induction perhaps through the formation of an inhibitor. If the same mechanism is postulated for Cestrum, one could explain the inhibitory effects of a 24-hour photoperiod for long-day induction.This publication has 1 reference indexed in Scilit:
