Student Learning Outcomes:
Upon completion of the course, students will be able to:
Untitled document
1.  Explain how vine microclimate affects vine growth, fruit quality and bud fruitfulness.
2.  Identify various canopy management techniques and explain how each can alter vine microclimate.
3.  Assess and evaluate canopy management practices.
4.  Make recommendations for improvement of vine canopy management.
 

Objectives: Untitled document
Upon successful completion of this course, students will be able to:
1. Define and give examples of grapevine canopy management techniques.
2. Compare and contrast various grapevine trellis support systems.
3. Describe the yearly vineyard cycle in the context of both vegetative
