Exogenous GA3 delays walnut fruit maturation and alters kernel fatty acid composition by modulating genes and hormones during development.
Regulation of walnut fruit maturation is crucial for delaying harvest and maintaining kernel quality. In this study, 'Qingxiang' walnut (Juglans regia L.) fruit were treated with 300 mg L-1 gibberellic acid (GA3) during 20-100 days after flowering (DAF) to assess its effects on fruit development, kernel nutrient compos...
