Physicochemical hydrodynamics of porous structures in vascular plants

ORAL

Abstract

Transport of sap flow through xylem conduits of vascular plants has been considered as a passive process, because the xylem conduits are regarded as inert, dead wood. However, plants can actively regulate water transport using ion-mediated response for adapting to environmental changes. In order to understand the active regulation mechanism of physicochemical hydrodynamics of porous structures in vascular plants, the effects of specific ion types and their ionic ratios on the water transport were experimentally investigated under \textit{in vivo }condition. Based on the experimental results, the principle of ionic effects will be explained through \textit{in-vitro} comparative experiments and theoretical considerations.
