Abstract

GA3 increased the extension growth of Impatiens balsamina L. till 56 days under 8- and 24-h photoperiods. Cycloheximide which decreased height slightly under inductive conditions at a later stage did not affect the GA3-promoted extension growth. Both GA3 and cycloheximide caused enhancement of the rate of differentiation, although this effect was temporary in the case of GA2. Cycloheximide does not affect photoperiodic induction, whereas it hastens and increases the magnitude of GA2-induced flowering.
