Topics on seedling production include containers, growing medium, irrigation, fertilization and the control of greenhouse environment. Principles and techniques of seedling quality assessment will also be covered. Topics on the silviculture of boreal forests include the environmental conditions, ecological processes and silvicultural characteristics of boreal forests, the dynamics and ecology of boreal understory vegetation, principles and methods of vegetation management, crop planning, site quality assessment, and silvicultural systems for major cover types of the boreal forest.

NRM 5273 - Tree Ecophysiology I

A study of ecophysiological principles and mechanisms of plant response to changes in the environment. The course will focus on assumptions and approaches of ecophysiological research, foliar gas exchange (photosynthesis and transpiration), long-distance transport of assimilates, and water relations.

NRM 5274 - Tree Ecophysiology II

A study of ecophysiological principles and mechanisms of plant response to changes in the environment. This course will further materials covered in Forestry 5273. A good understanding of photosynthesis, long-distance transport of assimilates and water relations is essential for taking this course.; The course content will focus on leaf energy budgets, mineral nutrient, growth and allocation, life cycles and biotic influences.
