Dynamics of sugar, organic acids, and related enzyme activities during fruit development and ripening. (A) Changes in contents of sucrose, fructose, glucose, malic acid, citric acid, quincy acid, and succinic acid during fruit development in ‘Junzao’ and ‘Qingjiansuanzao’; (B) Activity changes of key enzymes involved in sugar and organic acid metabolism. Values are means of three biological replicates ± SD. * and ** indicate significant differences between the two accessions at levels p < 0.05 and p < 0.01 by t-test, respectively.
