Mitigating WA38 Greasiness and Related Quality Defects (Ft Pierce)

WA-38 is a desirable apple cultivar, but tends to develop excessive greasiness and off flavor in storage. The project objectives are to: 1. Further define harvest maturity guidelines limiting greasiness of WA-38 in the cold chain. 2. Establish ethylene mitigation protocols that reduce WA-38 greasiness for both conventional and organic production. 3. Determine the limitations of wax/detergent to optimize wax in the post-storage cold chain. 4. Identify and determine protocols for mitigating off-flavors associated with greasiness.
