Abstract

This review paper presents a synthesis of all the results obtained in the Biology Group at Ispra during these last years, about the effects of various kinds of ionizing radiations on large populations of protoplasts. After a critical assessment of the protoplast system as a tool for radiosensitivity studies, the dose effect relationships, r.b.e. and split dose effects after gamma ray and fast neutron irradiations will be presented. The transmission of cytological heterogeneity from the leaf, the different radiosensitivity of leaves and regenerating protoplasts, the possibility of fractionation of the leaf protoplast population on an iso-osmotic density step gradient and finally, some considerations about radiosensitivities and genotypes, repair DNA in plants and in vitro mutagenesis will be given.
