Bulb formation in Allium cepa L. cv. Dorata di Parma, was promoted by ethylene (Ethrel 120 mg l −1 ) treatments. Application of the antiethylene complex silverthiosulphate (0.01 m M ) inhibited ethylene‐induced bulb formation, but did not affect photoperiod‐induced bulb formation. When the inhibitor of ethylene biosynthesis, aminoethoxyvinylglycine, was applied at 0.04 to 4 mg l −1 to onion plants under inductive photoperiodic conditions the bulb promotion was unaffected. Therefore, Ethrel‐induced bulb formation does not appear to be related to endogenous control of bulbing.
