- Abstract
Changes in the oxalate salts of plum (Prunus salicina L., Golden Japan) and cherry (Prunus avium L., Napoleon) leaves have been studied over a single growing season. It has been shown that the oxalate content is higher in plum than in cherry trees; soluble oxalates are absent from the latter. In cherry trees all of the oxalic acid is precipitated as calcium oxalate. In plum trees, ⅔ of the content is present as calcium oxalate and the rest as potassium oxalate. The formation of calcium oxalate takes place in parallel with the formation and maturation of the fruit and ends once the fruit has been harvested. The substantial difference observed in oxalate content between the two species, despite their very similar total organic-acid-anion contents, indicates important differences in the mechanisms contributing to maintenance of charge balance.
