Abstract

Pistillate flower formation in monoecious cucumber plants is increased when allyl trimethylammonium bromide is added to aerated solution cultures used as the root medium. By contrast, gibberellin induces staminate flower formation on gynoecious cucumber plants. The two chemicals also have diametrically opposite effects in tendril formation and vegetative extension.
