• budding: specialized form of grafting in which a single bud is used as a scion
• reasons for budding:

  • species
  • cost efficient
  • can make multiple trees out of a single bud stick
• Budding should be done when rootstock is active and bark is slipping
• Budding should be done when the scion is dormant
• T-budding must be done with dormant scions and active rootstocks
• T-budding must be done when bark is slipping
• budding: a specialized form of grafting in which a single bud is used as a scion rather than the typical grafting scion which is an intact piece of stem that usually contains multiple buds
• chip budding: can be done while the rootstock is dormant (not slipping)
• Chip budding provides for more flexibility and can be quicker to take
• Budding requires the production of callus tissue
• After a successful bud is formed, propagators must manipulate the rootstock to break the apical dominance
• To break apical dominance, you can use pruning or crippling
• In class, Poncirus trifoliata was used for citrus budding
• T-budding was used on citrus in class
• Chip budding cannot be used on fruit and nut trees
• The plant being propagated (represented by the bud) is referred to as the scion, while the plant being grafted onto is referred to as the rootstock. A small branch with several buds suitable for T-budding on it is often called a budstick.
