Abstract

See full text

A plant water dynamics sensor usable for measuring the dynamics of water flowing in a fine point of a plant such as a distal end of a new branch or a pedicel comprises a heater-equipped temperature probe including a temperature sensor and a heater; a temperature probe including a temperature sensor; an electrical resistance probe including an electrical resistance measurement electrode; and a support that supports the probes while the probes are aligned parallel to each other. The position of a xylem XY can be detected based on an electrical resistance measured at the electrical resistance probe, so that each of the temperature sensors can be arranged correctly in a position at a phloem PH or at the xylem XY. This facilitates attachment of a plant water dynamics sensor and water dynamics in a plant can be measured with high accuracy.
