Title: Regularity Analysis of Main Sugar and Acid in Fruit Development of Peach
Abstract: In order to discover the variation regularity of main sugar and organic acid during fruit development of peach,fruits of each developmental stage of 21 varieties were used to measure sucrose,glucose,fructose,sorbitol,malate,citrate and quinate using HPLC.Similar regularities of sucrose were found in different varieties,as steady or small growth in early stage,continued with a sharp growth 30 to 50 d before fruit mature.Small decrease was happened in some varieties 10 d before harvest.Similar regularities of citrate were also found in different varieties,as high content in early stage,and a sharp decrease 10 to 30 d after flower,continued with constant low content,then a small growth,content of citrate decrease before harvest in most varieties.No distinct variation regularities were found in fructose,glucose,sorbitol,malate and quinate.During fruit developing,significant correlation between sucrose and fruit size,fructose and glucose were found in all 21 and 20 varieties,respectively.Flavors of matured fruit were significant positive correlated with sucrose,pH and sugar/acid at 0.01 level,and significantly positive correlated with total sugar at 0.05 level.Flavors of matured fruit were significantly negative correlated with titratable acid,malate and total acid at 0.01 level.
