Abstract: Recent advances in the research on biological effects of electrostatics are summarized, including the influence of electric field dosage on biochemical and physiological reactions.The indexes of formation of the seeds and seedlings,changes in plant enzyme activity and the integrality of cell membranes are analyzed. The biological effect and possible physiological role of electrostatics are discussed at the cell and molecular levels in the hope of providing a scientific basis for wide applications of electrostatics in agriculture.
