Induction of multinuclear cells in the apical meristems of Allium cepa by geomagnetic field outrages

This paper is a result of a long-term study of the apical meristems of the Allium cepa L. seedlings against a background of naturally changing geomagnetic field. Multinuclear cells, large cells with large nuclei, and giant cells with giant nuclei were detected. Changes in cellular structures were revealed, and the time-course of this process was followed. Changes in the cellular structure of meristems were correlated with the fluctuations of magnetic field of the Earth. The experiments conducted with in vitro culture of apical meristems showed that the observed changes were regulated on the local level.
