Abstract
Pharbitis nil strain Violet, a sensitive short-day plant, flowered even under continuous light in a poor nutrient condition (culture in tap water). The content of chlorogenic acid (CGA) in the cotyledons of this plant increased in close correlation with floral induction under poor nutrition, and (aminooxy)acetic acid (AOA) applied at various concentrations or for various periods during the culture in tap water inhibited flowering in parallel with the suppression of CGA accumulation. Short-day-induced flowering was not accompanied by an increase in CGA content nor was it influenced by the application of AOA. Thus, CGA accumulation in the cotyledons or some related process was suggested to be involved in the flower-inducing process under poor nutrition, but not in that under short days. The application of exogenous CGA under standard nutrition did not induce flowering under continuous light. However, this does not deny the possibility that a high concentration of CGA in the cotyledons causes floral induction, since the CGA content of the cotyledons was not increased by exogenous CGA application.
