Mitigating gibberellic acid-induced effects on dormancy, shoot growth, and fruit development in persimmons when used to delay harvest

• GA₃ extends harvest of ‘Rojo Brillante’ persimmon and stabilizes market prices. • The optimal treatment is 30 mg L⁻¹ GA₃ applied 20 days before colour break. • Repeated GA₃ sprays enhance response but delay dormancy and reduce flower quality. • Yield losses in the following year increase with cumulative autumn treatments. • GA₃ or Promalin at budburst raised growth and fruit set, mitigating yield losses. The large-scale production of ‘Rojo Brillante’ persimmon in Spain relies on gibberellic ac
