Regularities of cytogenetical disturbaunces induction by low doses of radiation in barley germ root meristem cells

摘要

A range of small to barley germs was evaluated. It was shown that the relationship between the cytogenetic dis turbances yield and a dose in the region of small and close to small dosed has a nonlinear character and statistically trustworthy distinguished from spontaneous level of dose-independent plato in a range of 5.6-46.7 cGy. Statictical analysis of experimental data on the basis of the previously proposed concept allowed us to conclude that the behaviour of genetical disturbances in the range of low doses could be approximated by nonlinear model. It was discussed biological and applied consequence of the obtained results.
