A study was made of the effect of acute ..gamma..-radiation on incidence of chromosomal aberrations in apical and leaf meristem of the pine in the first and second postradiation vegetation periods. It was found that the radiosensitivity of these tissues is the same. In the second postradiation vegetation period, after exposure to a dosage of 1500-2500 rad, there is normalization of the parameters studied. Restitution of tissues can occur both as a result of recovery of involved meristem cells and by means of differentiation of subapical meristem cells.
