Аннотация: In conifers species introduced in arboretums and parks changes of karyological and cytogenetics parameters are observed. Variability of chromosome numbers (mixoploidy) and B-chromosomes occurrence are detected, also cultivars of conifers are characterized by changeability of chromosome numbers. Disorders of chromosomes morphology aПоказать полностьюnd increase of number of secondary constrictions are observed. Asynchronous in development of male generative sphere, longer duration of meiosis and wide spectrum of meiotic anomalies are revealed. The established changes probably results from acclimatization, and can be connected both with activity of regulatory processes and an increasing of pheno-typic and genetic diversity, that must be considered when implementing measures for the introduction of different species of conifers.
