Course Objectives: | HORT 4440/6440 is designed to:
1. improve one's understanding of the environmental physiology of plants
2. encourage application of physiological concepts to everyday horticultural
problems
3. demonstrate how plants modify microclimate, and conversely, how the
microclimate of horticultural settings can be modified to optimize
growth and reduce environmental stresses
4. reinforce physiological concepts, and develop problem solving,
scientific literacy, and small group communication skills through
laboratory projects. |
