Abstract
Non-melting-flesh peach fruits Wanhujing were used as materials,which were treated with 1μL/L 1-methylcyclopropene(1-MCP) for 20h at 20℃,to study the effect of 1-MCP on the degradation characteristics of cell wall polysaccharides and the effects of cell wall degradation enzymes on peach fruit softening.The results showed that 1-MCP effectively delayed the decline of peach fruit firmness and also delayed the increase of endogenous ethylene production.The rate of decrease in CDTA-2,Na2CO3,KOH,and CWM-residue contents were significantly lower than untreated fruit.1-MCP treatment could delay the dissociation of CDTA-soluble pectin polysaccharides 1-MCP also inhibited the degradation of galacturonic acid main chain composed of rhamnose and arabinose,galactose branched-chain in Na2CO3 soluble pectin polysaccharides.And it inhibited the degradation of hemicellulose and cellulose polysaccharide.The analysis of the changes of the activities of enzymes,combining with the character of the degradation of sugars during peach fruits treated by 1-MCP suggested that,by restraining the relative enzyme activities,1-MCP treatment can restrain the degradation of cell wall polysaccharides,thus delaying peach fruit softening.
