Effects of 1-MCP Treatment on Quality Changes of“Fuji”ApplesDuring Storage at Ambient Temperature

Abstract

Abstract: The effects of exogenously applied 1-MCP on physiological and quality changes in harvested apple cv.Fuji fruitswere investigated.Treatment with 1or 2μl/L 1-MCP significantly inhibited the senescence process of harvested apples,asmanifested in low levels of ethylene production and respiratory rate butin high levels of VC retaining and total soluble solidcontents.In fruits treated with 1-MCP,low levels of PE and PG activity were detected,the degradation of protopectin was inhibited,and fruit firmness was maintained at higher level in comparison with control fruits.The experimental results suggested that 1-MCPmight delay fruit senescence by inhibiting ethylene production,thereby keeping better quality during ambient temperaturestorage.

Key words: MCP, apple, ethylene, quality
