The water transport system of terrestrial plants relies on liquid water withstanding tension created in leaves by transpiration (Dixon and Joly 1895, Debenedetti 1996, Tyree and Zimmermann 2002).This tension increases when water is limited, leading to a heightened risk of emboli (gas blockages) forming in xylem conduits. package gensymb warning: not defining microWebDixon and Joly gave the theory that ascent of water in the plant through pored tracheary elements of xylem which uses cohesion-tension, transpiration pull and suction pressure developed in the leaf cells.
