History
ancient technique
practiced as early as 1,000 BC
employed widely by the
Romans centuries later
Grafting
two different plants are united
so they grow together as one
Scion - top - vegetative part
Stock - bottom - root part
Reasons for use
give plants stronger more
disease resistant roots
cause dwarfing
top working - grafting many
different varieties to the limbs
of one tree
Reasons for use
insert different variety for cross
pollination
propagate plants difficult to bud
Requirements
compatibility
must be related to each other to
enable the stock and scion to
grow together
Requirements
Scion wood
one year old
vigorous growth
Requirements
Timing
stock and scion should be
dormant or have no leaves
Matching of tissue
cambium of two matched plant
parts must come in close
contact with each other
cambium cannot be allowed to
dry out
Waterproofing
immediately after making graft,
cut surfaces must be covered
with a waterproof grafting
compound
