In order to investigate how root communicates with each other by the electric field, a root-mimetic device which generates electric field has been developed. The system is comprised by subunits such as (1) three carbon-tip electrodes, (2) a voltage source subunit which enables changing level and formation of source and sink by using analog multi-plexers and D/A converters, (3) Z-80 microprocessor as a local controller and (4) a computer which controls whole system through optical-isolated serial line. Consequently, it was shown that generated patterns of electric field by our system were similar to ones by infant root and that electric field formed around root changed by applying the system. Finally, effectiveness of the system was confirmed.
