Background. The study of the long-term effects chronic radiation exposure on plants and animals, which are still subject scientific discussion, is necessary to understand consequences accidents. After Fukushima nuclear power plant accident, some young pines spruces showed an increased frequency apical dominance cancelling. most probable cause observed morphoses associated with damage meristem coniferous by in first year when they received highest absorbed doses. If this hypothesis true, then even 8 years after accident it will be possible high degree probability detect level cytogenetic abnormalities intercalary needles from these populations. aim work was verify hypothesis. Materials methods. Five populations Japanese red pine territories contaminated radionuclides as a result at were investigated. spectrum determined ana-telophase analysis. Results. aberrant cells territory statistically significantly exceeds control all impact sites increases along dose rate. Although there no correlation between presence cancellation plants, radioactively characterized both dominance. Conclusion. Radiation meristems conifers doses, likely studied zone affected plant.
