Outline of Final Research Achievements

We newly proposed the microscale xylem-sap-dynamics (flow velocity) sensor that uses the measuring principle of the Granier method. We also fabricated micro-sensor chips for functional verification by using MEMS technology, and assembled them on a resin film for mounting on the epidermis of plants. Furthermore, we measured the sap dynamics by using a mimicked plant experimental setup and actual plant, and succeeded in measuring the flow velocity(0-500μm/s). We also proposed the microscale phloem-sap-dynamics (flow velocity and direction) sensor, and confirmed the possibility of sap dynamic measurement in the actual plant shoots. We demonstrated the feasibility of a novel nutrients dynamics sensor that can conveniently identify the phloem positions and extract pure photosynthates samples in agricultural situations.
