Localized spontaneous fluctuations of electric potential in shoots of different plants

Abstract


Sharp short-lasting voltage fluctuation is one of the components of plant electric activity. Common appearance of such fast signals (FS) in the stems of several species has been found. Observed spatial distribution of its amplitude excludes the possibility of an artefact, deriving from the electrode surface -- plant tissue interaction. The hypothesis that FS are due to action potential of a single cell or a small group of cells observed in a volume conductor is considered.
