Budding Flashcards
What is budding/bud grafting?
Form of grafting where the scion consists of a single bud attached to a thin layer of bark and wood
What is a budstick/budwood?
Source of the buds
What is slipping?
When the bark easily separates from the wood
What is the purpose of budding?
Bud is inserted into the rootstock then the portion of the rootstock above the bud is cut. New shoot grows!
It’s fast and makes full use of budwood
When is budding used?
Fruit trees, ornamental plants
What are the parameters of collection and storage of budsticks?
Budsticks should be collected early in the day with the top of the stem and all leaves removed
Stems are bundled in groups, wrapped, sealed, and stored at about -2C
What is t-budding?
Most common type of budding used for rootstocks that are from 1/4” to 1” in diameter
Can only happen when the bark is slipping
What is inverted T-budding?
Used in locations that have significant rainfall during the budding season as it prevents water from going into the cut and slowing down the healing process
Often used with citrus
What is patch budding?
Used for thick barked plants where the bark must be slipping
Budwood and rootstock bark should have the same thickness
What is chip budding?
Usually done when the rootstock is actively growing and when the bark is not slipping
Deeper cuts than in patch budding with the vascular cambiums lining up
What is change purse budding?
Bud with leaflets are cut from the budwood with the rootstock flexed and the bud inserted into the cut
The Leaf is tied to the rootstock and plastic film is used to cover the bud union and leaf and tied
What is change purse budding typically used for?
Black walnut, English walnut, butternut and pecan
What is double shield budding?
Used to overcome graft incompatibility when two budsticks are needed and a t cut is made into the rootstock
Why are two budsticks needed in double shield budding?
One budstick supplies the scion and the other supplies the intershield
The scion is matched to the intershield and the two segments are inserted into the rootstock
