Grafting
  • two different plants are united so they grow
    together as one
  • Scion - top - vegetative part
  • Stock - bottom - root part

4
Reasons for use
  • give plants stronger more disease resistant roots
  • cause dwarfing
  • top working - grafting many different varieties
    to the limbs of one tree

5
Reasons for use
  • insert different variety for cross pollination
  • propagate plants difficult to bud

6
Requirements
  • compatibility
  • must be related to each other to enable the stock
    and scion to grow together

7
Requirements
  • Scion wood
  • one year old
  • vigorous growth

8
Requirements
  • Timing
  • stock and scion should be dormant or have no
    leaves

9
Matching of tissue
  • cambium of two matched plant parts must come in
    close contact with each other
  • cambium cannot be allowed to dry out

10
Waterproofing
  • immediately after making graft, cut surfaces must
    be covered with a waterproof grafting compound
