Assess the sensitivity of cytogenetic methods of monitoring research condition coniferous forests

Cytogenetik studies of four South Ural coniferous species were conducted under the conditions of industrial pollution of diffirent character and intensity as compared to a control one. Scots pine among the analysed species and the estimation of pollen grain anomality and the level of chromosomal aberrations at ana-telophase mitosis stages, anatelophase I and ana-telophase II meiosis stages among other used methods is determined to be characterized by the greatest indication sensitivity.
