Abstract
Fruit growers are looking for effective solutions to preserve the high quality of apples after storage. Therefore, the aim of this study was to assess the impact of pre- and postharvest use of 1-MCP on the quality of ‘Gala Schniga® SchniCo Red(s)’ apples harvested at the optimal harvest date and at a delayed harvest date and stored for 9 months under conditions similar to DCA (0.6% CO2 and 0.6% O2). Four treatments: control (1-MCP untreated), 1-MCP treated 7 days before harvest (Harvista™), 1-MCP treated 7 days after harvest (Smart-Fresh™), and 1-MCP treated before and after harvest (Harvista™ + SmartFresh™) were used, respectively, for each of the above harvest dates. After 5, 7, and 9 months of storage and after an additional 7-day shelf-life period, the following properties were determined: flesh firmness, soluble solids content, titratable acidity, and ethylene production rate. The harvest date and the 1-MCP application date affected ethylene production rate which was reflected in fruit flesh firmness and acidity (p < 0.05). Apples collected at the optimal harvest date from trees sprayed with Harvista™ before harvest retained high firmness (>55 N) after 7 days of shelf-storage at 20 °C, even if previously stored for 9 months. Apples collected later showed firmness similar to the best preferred by consumers only if treated with 1-MCP after harvest.
