Grafting = joining together of plant parts so they
grow as a single composite plant
Asexual propagation
Two parts of graft
Scion = short piece of stem with several dormant buds
Stock = lower portion (stem and/or roots of another plant)
Stock chosen because:
»Control size of overall plant
Scion generally from the desired cultivar
»Influence the time to fruit maturity
»Influence winter hardiness
»Offer disease or stress resistance
