Activities of Indoleacetic Acid Oxidase and Peroxidase in Ripening Apple Delicious Fruits

Ao Liang-de, Wang Ming-xin and Liang Yu-fa   

Abstract: Peroxidase was extracted from the apple (Delicious) fruit and the apple stalk during the various stages of ripening. Activities of peroxidase and IAA oxidase of fruits are different.The activities of peroxidase and IAA oxidase in the apple stalk are much higher than that in the apple fruits. Gel electrophoresis revealed that the number of isozymic bands of peroxidase in the stalk (7–9 bands) were more than that in the fruit (6 bands). It is inferred that peroxidase in apple stalk might play a more important role in IAA and some other inhibitors oxidized before then went into the fruits.
