[Distribution of the intensity of free radical reactions at different stages of bud growth and in adult hydra].

The distribution of free radical reactions was studied by means of grafted copolymerization of 14C-acrylamide monomer in the ectoderm of growing bud and adult Hydra. Several states of regionalization were established in the process of bud growth: absence of local differences, presence of local differences and presence of the peak of free radical reactions in the hypostome region, characteristic of adult Hydra. The initiation of budding is not accompanied by the activation of free radical reactions in this region. No direct relationship between the metabolic regionalization and morphological rearrangements was found.
