The electric potential patterns around primary roots and lateral roots were measured in the growing process of adzuki bean (Azukia angularis) to investigate the lateral-root formation. The spatio-temporal patterns of the electric potential along lateral roots had the same characteristics as those which had been observed in primary roots; the stable pattern and the oscillation near the tip were observed. The patterns of the electric potential and pH along a primary root correlated with the emergence and growth of lateral roots. The pH value was low in the region where grown lateral roots existed. The electric field was applied to a primary root perpendicularly to its longitudinal axis for 24 hours. After the application of the electric field, the number of emerged lateral roots and the acidification of the primary-root surface at the electrically negative side were higher than those at the opposite side.
