Peroxidase activity in hooded and awned barley at successive stages of development

Abstract

The hooded (KK) and awned (kk) genotypes of barley differ in the amount of peroxidase activity at various stages of development. In hooded, this activity is at most stages higher than in awned, but it varies more from one stage to another, so that at certain stages, particularly the first leaf stages of young plants, it is lower. The peroxidase enzymes of the two genotypes are alike in electrophoretic mobility. Since peroxidase activity is particularly high in meristems of hooded at the beginning of their transition from the vegetative to the flowering condition, which is shortly before the first effects on morphogenesis can be observed, a connection between high peroxidase activity and the morphogenetic effects appears likely.
