Rose Flowering Schedule & Bud Induction
Application of Plant Growth Regulators to Adjust the Flowering Period of Roses
Ethephon
Spraying rose plants with ethephon extends the flowering period and significantly increases flower yield. Repeated spraying with 400 mg/L ethephon at the onset of leaf unfolding and during the peak leaf-unfolding stage can extend the total flowering period by 6 days.
Gibberellic Acid GA3
Spraying the entire plant with 100 mg/L gibberellic acid during the leaf-unfolding stage can advance flowering by approximately 6 days, although the flowering duration may be shortened.
