THE EFFECT OF DIHYDROZEATIN ON THE MOBILIZATION OF PROTEIN RESERVES IN THE COTYLEDONS OF CHICKPEA SEEDS

In chick-pea seeds, the axis seems to have a clear regulatory role in the processes involved in protein degradation since in its absence very little protein degradation is recorded. However, its effect on proteolytic enzymes varies according to the enzyme studied, as does the pH at which each of these enzymes exhibits its maximal activity. The application of dihydrozeatin during the incubation of seeds whose embryonic axis has been excised increases globulin degradation. The dihydrozeatin does not seem to have any effect on aminopeptidase activity while caseinolytic and carboxypeptidase activities are affected by this hormone. © 1990, Gustav Fischer Verlag, Stuttgart.
