We evaluated the efects of 1-methylcyclopropene (1-MCP) treatment and polyethylene (PE) flm liner application on the fruit quality attributes of cold-stored 'Gamhong' apples. Flesh frmness was better retained with 1-MCP treatment than by PE flm liner treatment, regardless of 1-MCP treatment time. Titratable acidity was also well-maintained during cold storage. In contrast, the soluble solids contents were not consistent during storage. The 1-MCP treatment greatly reduced the internal ethylene concentration, when compared with the control and PE flm liner treatments, irrespective of the 1-MCP treatment time. The weight loss of the fruit was greatly reduced by the PE flm liner treatments, as well as by the 1-MCP treatments. The fruit peel color variables were not afected by the 1-MCP or PE flm liner treatments during cold storage. Nevertheless, the peel color variables were greatly diferent in the shaded tissue than in the sunny side during cold storage. Our results indicate that 1-MCP treatment, as well as PE flm liner application, should be highly recommended for retaining the fruit quality of cold-stored 'Gamhong' apples.
