Influence of urbanized territories on mitotic activity of onion root meristem cells (Allium cepa L.)

The article presents the results of the use of cytogenetic methods in assessing the impact of urbanized territories on the mitotic activity of cells of the onion root meristem Allium cepa L. The research was carried out on 4 sites with different anthropogenic load. The Allium test research method is based on the analysis of the values of the mitotic index of the meristem cells of the Allium cepa L. root sprouted on the melted snow water of the studied points. The study showed that pollution of urbanized territories has a mutagenic effect, causing the formation of chromosomal aberrations and other types of mitosis pathology in the cells of the apical meristem of the roots of Allium cepa L.
