Subject Description

On completion of this subject, students should have an understanding of the variety of molecules that are present in trees, the principles of metabolism and energy transfer, and the physiological processes that determine the growth and productivity of trees. The course thus covers the macromolecules of plant cells; membranes and permeability; water relations, transpiration and stomatal physiology; ion uptake, mineral nutrition and mineral deficiencies; photosynthesis, photorespiration, respiration and energy transfer; biomass assimilation and translocation; and cell wall structure and lignin biosynthesis. Practical classes provide an introduction to greenhouse techniques and methods for plant handling and measurement. The integration of these basic biochemical and physiological processes into the life cycle of a tree, and the effects of genetics and the environment, are covered in 211-302 Tree Development.

Assessment

One 3-hour written examination at the end of the semester. Marks will also be given for assignments and practical work.
