[Irradiation as a test-factor revealing dark DNA repair capacity of seeds].
Dark repair of DNA was studied in embryos excised from the advanced sugar beet seeds. Significant increase (from 19 to 321%) in the level of dark DNA repair has been established for all studied conditions of the advanced treatment. Acute -irradiation has been used to investigate the ability of advanced seeds to repair additional DNA damages caused by a standard irradiation dose. It has been concluded that irradiation factor allows to test capacity of DNA repair systems. The later, we suggest, can be used to define the optimal conditions for the seed advancement.
