STUDY OF THE AFTEREFFECT OF RADIATION ON PLANT CELLS FROM THE VIEWPOINT OF RADIATION PROTECTION (in Russian)
Dry barley seeds were tested for determining the aftereffect of radiation in view of developing protection against it. An attempt was made to differentiate between the effect of the primary neutrons on the irradiated cells and the delayed phenomena. No metabolic processes took place in the dry seeds at the time of the irradiation which was carried out by means of a Co/sup 60/ gamma source to an integral dose of 10 kr. The so-called oxygen aftereffect'' and the temperature aftereffect'' were determined by making use of a previously described method developed by the authors (Doklady Akad. Nauk SSSR, l26: 191(1959) and 133: 462 (I960)). The irradiated seeds were dipped in a 0.0I M solution of alanine. Results indicated that this amino acid exerts a postirradiation protective action as could be seen from the chromosome aberration. This property appears to be connected with the reduction of the oxygen-type aftereffect and probably involves a mechanism of nonspeciflc blocking of the access path of oxygen to the injured portion of the seed cells.
