Вплив фотостимуляції на біоелектричну реакцію листя кукурудзи
Effect of photostimulation on maize leaves’ bioelectrical response

Summary/Abstract: Dynamics of the maize leaves’ biopotentials evoked by white, blue, green and red light stimuli with an intensity of 90 Lx illumination is analyzed. Qualitative similarity in dynamics of plant’s bioelectrical response to white and colored stimuli is determined. Hyperpolarization levels are quantitatively estimated for each experimental series. Dependence of the total hyperpolarization levels on the photostimulus wave length is detected. Mean amplitude of the hyperpolarization potentials lessens when the wave length decreases: from 57.7 mV under the red light to 27.7 mV under the blue one. Probable forms of bioelectrical response initiation in photostimulated plants are analyzed.
