Pretreatment effects of different gibberellins, helminthosporic acid, cyclic AMP and kinetin on subsequent IAA-induced elongation were tested in cucumber hypocotyl sections. Gibberellin A_7 was more active than GA_3, while gibberellin A_8 was almost inactive. Both helminthosporic acid and cyclic AMP mimicked GA_3-action, though the degree of their activity was less. Kinetin pretreatment resulted in marked inhibition of IAA-induced elongation. The pretreatment effect of GA_3 was also reflected in a greater response of the sections to synthetic auxins.
