Bioelectric Oscillations of Bean Roots: Further Evidence foraFeedback Oscillator II. intracellular Plant Root Potentials

Abstract

Intracellular measurements using microelectrodes have revealed steady electronegative potentials across cell boundaries. Injury potentials and, in some cases, spontaneous oscillations with periods similar to those observed extracellularly have also been recorded. The amplitudes of these oscillations reach a maximum in the outer cortical cells of the root's elongating zone.
