The data showed that stimulation of wheat seed germination by brief exposure in a 50 Hz electromagnetic field (10 min.) depended on the extent of membrane stretching upon seed swelling in sucrose solutions. Increasing osmotic pressure progressively suppressed seed germination. The exposure to the electromagnetic field improved seed germination capacity under all experimental conditions. The authors suggest that this finding confirms the effect of low frequency electromagnetic field on the release of peripheral proteins from membranes. Prolonged exposure (6 days), on the contrary, decreases the germination rate and retards seedling growth.
