[Seasonal differences in the regeneration of planarians subjected to long-term electromagnetic shielding]

It has been found that the regeneration of planarians is most intensive in summer and least intensive in winter. In spring and autumn, the index of regeneration and the velocity of movement are higher than in winter but lower than in summer. Long-term electromagnetic shielding modifies the intensity of regenerative processes, and this effect is season-dependent. The stimulation is most clearly pronounced in winter and least pronounced in sommer and decreases with increasing duration of shielding. In spring, only a tendency to the stimulation of regeration is observed, which increases with the length of the observation period.
