Photosynthesis As a Function of Short Day Induction and Gibberellic Acid Treatment in <i>Bougainvillea</i> “San Diego Red”

Abstract

Short day induction in Bougainvillea "San Diego Red" increases photosynthetic rates in mature leaves; gibberellic acid treatments, which inhibit flowering, cancel the short day effect. These results lend support of a nutritional hypothesis that suggests that in Bougainvillea assimilate supply to the reproductive axis increases before floral initiation and during flower development.
