Title: Biological after-effect and long-lived free radicals in irradiated seeds

Abstract

Biological damage in irradiated barley seeds was measured as damage to seedling growth, survival of the seed to a mature plant, chromosomal aberrations, or mutation. The various damages were found to be related. It is postulated that the biological after-effect in irradiated dry seeds is due to decay of the long-lived free radicals, derived from radicals initially generated by the radiation, and persisting after the irradiation is over. Results are reported from studies on the effects of various treatments, such as water, oxygen, other gases, and temperature, on postirradiation free radicals and on the after-effect phenomena in irradiated barley seed.
