Abstract

A synthetic (reputed) kinin, SD 8339, at 1000 parts per million in alcohol solution, applied to flower clusters of a male grapevine about 3 weeks before anthesis, completely converted the flower sex from male to hermaphrodite. Indolebutyric acid, 2,3,5-triiodobenzoic acid, 2-chloroethyltrimethylammonium chloride β-naphthoxyacetic acid, β-indoleacetic acid, α-naphthaleneacetic acid, and gibberellin A3 failed to modify the sex.
