The article shows the stimulating effect of alternating magnetic field at the frequency of 6 and 12 Hz and induction of 25 mT on mitotic activity in apical root meristems of dicotyledon germs at onehour exposure of latent and sprouting seeds. The effect is observed if the seeds germinate during 3 days after the exposition. Additional impacts with 2 days range do not cause significant stimulation level alteration in germs.
