Abstract

Peroxidase, indoleacetic acid-oxidase, alkaline, and acid phosphatases were detected in dry starchy endosperm (minus aleurone) of wheat grain. The isoperoxidase pattern differed in different parts of the dry grain. Several new isoperoxidases were found in embryos after soaking. The intensity of isoperoxidases in aleurones was enhanced in the presence of embryo or 2 μM GA3 after 24 hours of soaking, but decreased after 72 hours. Indoleacetic acid and kinetin had no effect on isoperoxidase of aleurone. Actinomycin D and cycloheximide had no effect on isoperoxidases of aleurones from embryonectomized or naturally occurring embryoless grains. However, these two inhibitors increased the intensity of isoperoxidases in aleurones of intact embryonated grains after soaking.
