Bioelectric Fields of Bean Roots and their Relation to Salt Accumulation

Abstract

The bioelectric field of a bean root growing in a weakly conducting solution is examined. It is estimated by a method which is described, that a total current of about 3 X 10-7 A flows through the external medium due to the bioelectric source, resulting in power dissipation outside the plant of about 10-9 W. This is considered in relation to respiratory energy production in the root.
