Summary
Gibberellin A4/A7 was compared with GA3 for staminate flower induction on an inbred gynoecious cucumber line grown under field conditions in Michigan. Gibberellin A4/A7 spray applications at 50 ppm were found to induce significantly greater numbers of staminate flowers than GA3 applied at 1000 ppm without causing excessive stem elongation or brittleness often associated with high dosage of GA3.
