主　　题：grape sodium dehydroacetate DNA methylation MSAP shelf-life 

摘      要：In this study,we tested the ability of sodium dehydroacetate(SD)to extend the shelf-life of‘Kyoho’*** the different concentrations of SD tested(0,0.01,0.1 and 1.0 mmol L^(-1)),0.01 mmol L^(-1) SD was the most effective in prolonging the shelf-life of‘Kyoho’*** with the control,the weight loss rate,browning index and hydrogen peroxide(H_(2)O_(2))and malonaldehyde contents were significantly lower in the 0.01 mmol L^(-1) SD treatment,whereas the healthy berry rate,berry firmness,total soluble solids(TSS)content,ascorbic acid content and superoxide dismutase(SOD)activity were significantly *** addition,an analysis of‘Kyoho’grape DNA using methylation sensitive amplification polymorphism(MSAP)markers showed that the average DNA methylation level was significantly higher in the 0.01 mmol L^(-1) SD treatment than in the ***,these results indicate that 0.01 mmol L^(-1) SD could be used to extend the shelf-life of‘Kyoho’***,a strong connection between reactive oxygen species(ROS)metabolism and DNA methylation change during storage was revealed.
