What is plant grafting?
Click to flip
Plant grafting is a horticultural technique where tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together.
Click to flip
What are the benefits of grafting?
Click to flip
Benefits include disease resistance, improved growth rates, increased fruit production, and the ability to combine different plant varieties.
Click to flip
What is a scion in grafting?
Click to flip
A scion is a young shoot or twig used in grafting, which will form the upper part of the grafted plant.
Click to flip
What is the role of the rootstock in grafting?
Click to flip
The rootstock provides the root system for the grafted plant and often contributes disease resistance or vigor.
Click to flip
Describe the cleft grafting technique.
Click to flip
Cleft grafting involves cutting a split into the rootstock and inserting one or more scions into it. It's commonly used for joining small scions to a larger stock.
Click to flip
What is the purpose of a whip and tongue graft?
Click to flip
The whip and tongue graft is used to join similar sized stock and scion and provides a large surface area for cambium contact, which improves the chances of successful grafting.
Click to flip
How does budding differ from grafting?
Click to flip
Budding involves inserting a bud from one plant under the bark of another plant, while grafting typically involves joining stems or branches.
Click to flip
What is a successful graft union?
Click to flip
A successful graft union occurs when the grafted tissues grow together properly, allowing for the transfer of nutrients and water between the rootstock and scion.
Click to flip
What role does cambium play in grafting?
Click to flip
The cambium is a layer of tissue crucial for growth in plants, and successful grafting requires aligning the cambium layers of the scion and rootstock.
Click to flip
What is bridge grafting used for?
Click to flip
Bridge grafting is used to repair a damaged area on a tree, such as bark ring damage caused by pests or winter injury.
Click to flip
How can environmental conditions affect grafting success?
Click to flip
Temperature, humidity, and timing can greatly influence graft success, as plants need favorable conditions to heal and grow.
Click to flip
What are inarching techniques?
Click to flip
Inarching involves grafting a scion onto a rooted plant as a way to form new root systems or repair damaged ones.
Click to flip
What is the difference between topworking and grafting?
Click to flip
Topworking involves grafting new scions onto mature trees to change the fruit variety, while grafting can apply to the general technique of joining plant parts.
Click to flip
How does budding lead to plant propagation?
Click to flip
Budding propagates plants by inserting a single bud from one plant onto another, where it can grow into a new shoot identical to the parent plant.
Click to flip
What precautions should be taken during grafting?
Click to flip
Precautions include using clean, sharp tools, ensuring good contact between cambium layers, and protecting the graft from pests and extreme conditions.
