Understanding how trees grow is a foundation for the practice of arboriculture. However, if one picks up a current article about woody plants, one can be overwhelmed with jargon (determinate, indeterminate, apical dominance vs. apical control, isohydric and anisohydric responses to water stress, embolism, cavitation, hydraulic redistribution, hydraulic architecture, hydraulic vulnerability, carbon starvation, role of aquaporins in membrane function, …).  Is it all garbage or can you improve your understanding of trees by having these terms explained?

This course, taught by Tom Hinckley, UW Emeritus Professor of Woody Plant Physiology, will cover the basics of tree biology and how trees grow in response to their environment. Topics to be covered include meristems and their functions, growth patterns, tree responses to stress, tree competition and mortality, and how trees get water from roots to their canopies. The class includes a lecture plus hands-on examples with whole trees and tree parts from a range of circumstances and species. We will put current concepts of tree growth and development into a form that arborists can use in their work.
