Inhibition of Flowering in Mango (Mangifera indica L.) by Gibberellic Acid1

Abstract

Gibberellic acid (GA 3 ) at concn of 10 −1 , 10 −2 m applied on the buds of “on” year ‘Dashehari’ mango tree just before flower bud differentiation, inhibited flowering 95% and 75%, respectively. Concn of 10 −3 and 10 −4 m inhibited flowering to a much lesser extent, but delayed the emergence of panicles by nearly 2 weeks.
