The correlation between the hexose to Suc ratio (w/w) and soluble acid invertase activity. A unit of enzymatic activity (U) equals 1 μmol of Suc hydrolyzed per minute under the assay conditions described in “Materials and Methods.” Regression analysis was performed with the PROC REG procedure (SAS Institute Inc., 1988). *** denotes that the correlation is significant at the 0.1% level. Each point is the mean of three to four observations.
