Abstract
The effects of 1-MCP treatment on physiology and fruit quality of pear(Pyrus bretchneideri) were studied during storage at(23±1) ℃ in this paper.The results showed that 1-MCP restrained ethylene release and respiratory rates intensively,depressed the accumulatation of MDA and increase of fruit cytomembrane leaks outs nature,1-MCP also delayed the content of chlorophyll decline and pericarp yellowing,preserved fruit quality preferably.The effect of 1-MCP treatment on storage life of pear was distinct,among three concentrations of 1-MCP treatment,the effect of 1.0 μL/L was optimal.
