A New Approach to the Study of Electric Fields produced by Growing Roots

Abstract

THE electric fields primarily developed across the walls of plant cells give rise to an integrated field associated with a growing plant organ. Information from the literature with regard to such electric fields associated with plant organs is contradictory and has led to conflicting theories; and the conflict in experimental evidence has never been satisfactorily resolved. An investigation of the literature seems to us to show that artefacts developed at points where measuring probes make contact with the plant would, in most cases, swamp the normal field which it is desired to investigate.
