COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Explain the physiology of callus formation for grafting/budding success.

2. Describe various budding and grafting methods.

3. Demonstrate effective chip budding/ T-budding techniques.

4. Recognize scion-rootstock incompatibility symptoms and recommend an action plan.

 

Objectives:

At the conclusion of this course, the student should be able to:

1. Differentiate between sexual and asexual propagation.

2. Compare and contrast various grapevine propagation methods.

3. Discuss the purpose of budding and grafting for vineyard production.

4. Describe various budding and grafting methods used to graft over existing grapevine.

5. Describe the anatomy and physiology of internal and external budwood structures.

6. Describe practices and techniques necessary to assure that bud wood is virus free.

7. Determine compatibility of vine and rootstock to avoid grafting failure.

8. Describe proper storage and sanitation techniques of budwood.

9. Properly prepare rootstocks and vines for budding and grafting.

10. Explain appropriate practices for post grafting vine care.
