Environmental Plant Physiology Lecture

Environmental Plant Physiology (PSC 5270/6270) provides a link between the cellular and biochemical analysis in plant physiology and more applied aspects of plant growth. Environmental Plant Physiologists examine the ways that physiological processes are integrated to cause whole plant responses in communities. The subject matter is related to Plant Ecology and Stress Physiology. The basic concepts and approaches are applicable to all types of plants, from petunias to potatoes to plums; grown in pots or in soil, in greenhouses or in the field.

Emphasis will be placed on the relationship between environmental parameters (radiation, temperature, water, nutrients), and their effect on physiological processes (photosynthesis, respiration), and plant responses (leaf expansion, partitioning of dry mass, water status, and transpiration). We will examine the integration of these plant responses into models that help to better understand and predict growth and yield.
