Summary: Understanding of the mechanisms and pre- and postharvest factors affecting scald development are necessary for developing procedures to reduce scald loss. This project found that the reduction of α-farnesene and increase in CTols are associated with the development of scald. Antioxidant metabolites played important roles in controlling scald. High ACU, high fruit Ca content, sunlight exposure, and optimum harvest maturity resulted in high antioxidants at harvest and reduced scald. Optimizing practices in ReTain, Harvista, O2 regimes, and Lovastatin coating provided a great scald control than ethoxyquin application alone.
