The systems of the electrophysiologic regulation of the plant organism ensuring the mechanisms of its spatial and temporal organization of the surface bioelectric potentials have been studied. The systems of the rapid and slow electrophysiologic signalization in plants (when the electric signal is transmitted from one plant to another in the absence of the water-ion canal, as well as under conditions of the electromagnetic distant induction of the seedling leftness and rightness in horizontal and vertical directions) have been identified. An electrophysiologic mechanism of the connection between above-ground and under-ground parts of the plant via a photoinduced electric signal, moving from leaves to roots and stimulating the inflow of mineral nutritive elements into plants before the chemical signal reaches the roots (photoassimilates) has been found out. The electrophysiologic action of untraditional stimalators – laser and -irradiation – on the plants has been discovered. A specific influence of the laser irradiation (its polarization, coherence, mono- chromaticity, power, modulation) and -irradiation (dose power and dose) on the parameters of the electric signals induced by them in plants has been shown.
