The mechanisms of induction of cytogenetic damage to plant meristematic cells caused by combined effect of heavy natural radionuclides and heavy and alkaline metals

摘要

The analysis of experimental data on the combined effect of ~(232)Th and water from melted snow containing metal ions from industirally loaded territories on Tradescantia (clone 02) and on Allium shoenoprasum meristematic root tip cells treated withheavy natural radionuclides from natural water sources in the area of radioactive wastes storehouse is presented. It was demonstrated that plant meristematic cells reponse to heavy metals and heavy natural radionuclides, both from two-component model system and from natural water sources, have connom features.
