Water Movement In Trees
University Outreach Publication
Of all the resource components of stress impacting tree survival and growth, water stress is the most prevalent. Water is the single most important substance for tree life, comprising 80% of tree substance. All the life processes of a tree take place in water — food making, food transport, food storage, food use, and defense. Water is a reagent in chemical reactions, a chemical bath for other reactions, a transporter, a hydraulic pressure liquid, a coating, buffer, and binder. Water is a universal liquid workbench, chemical scaffold, and biological facilitator.
