Flower Induction in Japanese Chrysanthemums with Gibberellic Acid

H Harada et al. Science. .

Abstract

Gibberellic acid, when applied in lanolin to apices of three Japanese varieties of Chrysanthemum morifolium, induced bolting and flowering. These varieties are not sensitive to photoperiod but require a cold treatment in order to flower. On the other hand, the varieties of Chrysanthemum which belong to the short-day group are not induced to flower by gibberellic acid.
