Starking Delicious. Freshly harvested fruits were treated with the fumes of 1-MCP in a closed polyhouse of 4 m³ for 24 hr. It was immediately followed by placing fruits under ambient storage condition and the fruits were analysed after 14, 21 and 28 days of storage under ambient storage condition. Fruits treated with 1-MCP retained all the important constituents, viz fruit firmness, acidity, TSS, starch over the untreated fruits. Fruits from Site 1 when treated with lower concentration of Smart fresh (280 mg) significantly retained almost all the quality attributes of apples at ambient storage in 28 days storage. Similarly, in Site 3, 4 treated apple higher concentration of Smart fresh (560 g) retained better quality characteristics than the lower concentration of Smart fresh and untreated fruits. In addition of this fruits harvest from Site 2 and 4 (Kinnaur) retained better storage quality characteristics in comparison to Site land 2. 收起
