Effects of 1-methylcyclopropene Treatment Combined with Modified Atmosphere Package on Quality and Energy Metabolism of Cold Stored Amygdalus persica ‘Hujingmilu’ Fruit

Fruits of Amygdalus persica‘Hujingmilu’ were harvested in Jiaxing, Zhejiang province in July 2013. Experiments were conducted on effect of 1-methylcyclopropene (1-MCP) treatment combined with polyethylene film packaging (MAP) on quality and energy metabolism of cold stored and shelf life fruits. The result demonstrated that fruits pretreated with 1 μL/L of 1-MCP for 12 h and packaged with 0.02 mm polyethylene film at 85%-90% relative humidity had lower decay index, better firmness, more content of total soluble solids (TSS) and vitamin C (Vc), better activities of succinic dehydrogenase (SDH) and cytochrome C oxidase (CCO), more content of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) and energy charge (EC) level than that of the control(no 1-MCP treatment but packaged with 0.02 mm polyethylene film). The experiments resulted that 1-MCP treatment combined with MAP was effective in reducing decay, delaying afterripening of fruit.
