a
For all of the compounds except soluble starch the data are expressed in micromoles per gram (dry weight). The data for soluble starch are expressed in milligrams per gram (dry weight). The data are means based on three replicates, and the values in parentheses are standard deviations. The pH values at the periphery, the intermediate position, and the center were 3.87, 3.71, and 3.63, respectively.
