摘要：

Plums cv. 'Black Diamond' were treated with concentrations of 0, 500 or 750 ppb 1-Methylcyclopropene (1-MCP) for 24 h at VC and then stored at VC. After harvest and after 10, 20, 30 or 40 days at 1degreesC, fruit were transferred to 20degreesC for 8 days simulating shelf-life. Ethylene emission of plums was strongly inhibited by 1-MCP and levels of CO2 production were significantly higher in non-treated fruit. Control plums exhibited a rapid flesh softening while 1-MCP treatments showed high values of firmness during the storage. 1-MCP treatment delayed color evolution, control fruit showed lower 'L', 'a' and W values (Hunter Lab parameters) compared with treated plums. No significant differences among treatments were detected in sugar content; nevertheless 1-MCP retarded the acidity decline. Our results demonstrated that 1-MCP treatment resulted in delaying ripening and senescence processes and improved fruit quality during cold storage and subsequent shelf-life.
