Аннотация: The influence of geomagnetic field (GMF) outbursts on the cellular structure of root apices of Allium сера L. was established. The tips of roots and shoots were fixed twice per day during a 24-day period. Abnormal binuclear, tetranuclear cells, large cells with large nuclei, and giant cells with giant nuclei were observed in the meristem zones of the root apices. They were surrounded by mononuclear diploid cells. «Within some days of the experiment, the amount of polynuclear cells comprised as much as 20% of all the meristem cells. The graphical presentation of this process shows peaks and troughs in the number of polynuclear cells. By comparing this with the changes in the GMF characteristics at the same days, we found a striking correlation between the two. The in vitro experiments on isolated root tip meristems allowed us to exclude the possibility of centralized regulation of cell structure changes being affected by the mutual exchange of metabolites between organs of the whole plant. The artificial screening of the GMF led to a significant decrease of cells with enhanced nuclear DNA content. The same plant cells demonstrated greater sensitivity to fluctuation of GMF under geographical conditions of high-latitude.
