Exogenous Pre-harvest Application of Abscisic and Jasmonic Acids Improves Fruit Quality by Enhancing Sugar Synthesis and Reducing Acidity in Pomegranate (Punica granatum L. cv. Wonderful)

Abstract One of the major issues with pomegranate production in arid and semi-arid climate is white arils fruit. The known plant regulators abscisic jasmonic acids play a variety roles growth reduction abiotic stresses. However, little about their application to improve quality fruit, particularly arils, environments. Herein, experiments, this study, were performed two consecutive seasons 2020 2021 on 10-year-old Wonderful trees spotlight improvement aril coloration fruit by spraying under climatic conditions. Fifteen subjected five treatments (three replications for each). tested included acid (ABA) at concentrations 600 800 µg −1 mL, (JA) 10 15 Mm, control treatment (distilled water). physical chemical characteristics improved significantly when treated or acids. foliar addition ABA mL increased anthocyanin index 96.74 114.75%, respectively, first year 49.48 67.62% second year, comparison control. was more effective than enhancing most properties, especially index. high level (800 mL) gave minimum acidity highest quality. Abscisic induces enhances pomegranate. In conditions, it recommended spray increase coloration.
