The role of an essential hormone controlling sex expression in cucumber was studied. A potent anti-ethylene agent, AgNO3 completely inhibited pistillate flower formation caused by IAA, ACC [1-Aminocyclopropane-1-carboxylic acid] or ethephon. Inhibitors of ethylene biosynthesis, AVG [aminoethyoxyvinylglycine] and CoCl2 also suppressed feminization due to exogenous IAA or ACC. Though AVG also suppressed ethephon-induced feminization, this may be due to the 2nd effect of AVG rather than the effect on ACC biosynthesis. Ethylene is a major factor regulating feminization and exogenous auxin induces pistillate flower formation through its stimulation of ethylene production, rather than ACC production.
