Вплив Локального Рентгенівського Опромінення На Біоелектричну Активність Листя Кукурудзи

Abstract

Dynamics of maize leaves biopotentials evoked by X-rays stimuli is analysed. Qualitative similarity in dynamics of plant’s bioelectrical response is determined. Hyperpolarization levels are quantitatively estimated for every series of the experiment. Dependence of the summarized hyperpolarization levels on photostimulus wave length is detected. The fact is ascertained that mean amplitude of hyperpolarization potentials reduces from 57.7 to 27.7 mV when the wave length decreases. Probable mechanisms of the initiation of photostimulated bioelectrical response are analysed.
