1. Grafting

2. History ancient technique practiced as early as 1,000 BC
employed widely by the Romans centuries later

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
