The scientific study of how trees grow and develop. Tree physiology is a discipline of the plant sciences that aims to understand how trees live, function, and grow. It encompasses genetics; biochemistry; cellular, tissue, and organ functions; and interactions with environmental factors. Furthermore, although many physiological processes are similar in trees and other plants, particularly at the molecular and biochemical levels, trees possess unique physiologies that help determine their outward appearance (Fig. 1). These physiological processes include carbon relations (photosynthesis and carbohydrate allocation), cold and drought resistance, water relations, and mineral nutrition.
