Cytogenetic responses of birch to stress factors

The following range of changes in response to anthropogenic stress has been revealed in experimental birch seedlings relative to control: increased mitotic index, the range and frequency of abnormal mitoses, number of cells with persistent nucleoli, and number of cells in prophase. Cells with vacuol...

Description
Summary:The following range of changes in response to anthropogenic stress has been revealed in experimental birch seedlings relative to control: increased mitotic index, the range and frequency of abnormal mitoses, number of cells with persistent nucleoli, and number of cells in prophase. Cells with vacuolated cytoplasm were also observed. The mutagenic pressure on the organisms in the industrial areas of Voronezh demonstrated a trend to increase, which points to their high environmental pollution.
