[Cellular radioprotective mechanisms to the action of cadmium ions on pea seedlings].
The reaction of pea (Pisum sativum L.) seedlings on the test--action (gamma-radiation) depending on a phase of seedling reaction on modifying action of cadmium ions was investigated. The existence of correlation between growth rate of the seedling main root and proliferative activity of root apex meristem and the type of radiomodificating effect was established. Radioprotective (radioadaptation) effect was observed at the 5 Gy dose irradiation of the seedlings at the final moment of hypercompensatory phase of the growth reaction on the action of 0.625 MkM CdSO4.
