Highly pure phloem-sap-extraction sensor device for direct component analysis of nutrition in plant shoots

Abstract

This paper describes a highly pure phloem-sap-extraction sensor device that mounts a phloem position-identification sensor. Convenient methods of artificially extracting highly pure phloem sap for quantitative analysis of plant nutrition have yet to be established. To realize direct analysis of nutrition as well as long-term monitoring of its component fluctuation, we propose a novel sensor device that can distinguish phloem and xylem positions stably for a long time and extract only pure phloem sap.
