Abstract
AN ELECTROCHEMICAL INSTRUMENTATION SYSTEM WILL BE DESIGNED AND CONSTRUCTED TO DETERMINE ON COMMAND PLANT WATER STATUS BY MEANS OF CYCLIC VOLTAMMETRY AND/OR COULOSTATICS. THE APPROACH IS BASED ON THE CHANGE IN ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE DURING THE NORMAL IRRIGATION CYCLE. A THREE WINDOW MICROPROBE WILL BE FABRICATED ON A SILICON WAFER SUBSTRATE USING THE PLANAR TECHNIQUES COMMON TO SEMICONDUCTOR ELECTRONICS. THE PROBE WILL BE PLACED IN THE MAIN STEM OF COTTON PLANTS IN COMMERCIAL FIELDS. SOLAR DRIVEN ELECTRONICS WILL THEN APPLY THE IN VIVO ACTIVE ELECTROANALYTICAL METHODS TO MONITOR THE CHANGE IN THE ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE.
