Abstract
The -irradiation of seeds of maize and wheat with the stimulative doses causes the lowering of the negative significance of the surface bioelectrical potentials and the increase of the intensity of Kirlian lumi- nescence of the leaves of 1520 days old seedlings. The effect maintains during 3 days after the level of control. The marked biophysical parameters can be used for the express-appraisal of the stimulative doses of the pre-sowing -irradiation of seeds of agricultural plants.
