Induction of male flowers on female plants of Cannabis sativa by gibberellins and its inhibition by abscisic acid

Abstract
Gibberellins (GA3, GA4+7, GA7 and GA9) induce male flowers on female plants of Cannabis sativa. This is, depending on concentration, partially or fully inhibited by abscisic acid (ABA). The ABA effect can in turn be partially overcome by increasing the concentration of GA3.
