Abstract

Gibberellic acid (GA) used as a foliar spray on ‘Renaissance Red’ poinsettia (Euphorbia pulcherrima) greatly increased flower stem length without lengthening production time or other adverse effects. A concentration of 10 mg L^-1 GA₃ applied weekly for the five weeks prior to onset of short days was most effective.
