Scion
Also written scionwood, graftwood. Each is a name for the same thing, which is why none of them has an entry of its own.
Definition
A length of dormant one-year-old shoot from the cultivar to be propagated, joined to a rootstock so that it becomes the fruiting part of the tree.

- Orchard
- Also written
- scionwood, graftwood
In more detail
Every tree of a named cultivar is a clone descended from scion wood, ultimately from the original seedling. That is why a cultivar can be five hundred years old as a variety while no individual tree of it is.
Related terms
Terms that belong to the same part of the subject, or that this one is routinely confused with.
Orchard
Rootstock
The root system onto which a fruiting cultivar is grafted. It governs the tree’s eventual size, its speed into bearing, its anchorage and its tolerance of soil conditions, without changing the fruit itself.
Orchard
Graft
The joining of a scion to a rootstock so that their cambium layers unite and grow as one tree. It is the only reliable way to reproduce an apple or pear cultivar.
Orchard
Chip budding
A grafting method in which a single bud with a chip of wood behind it is fitted into a matching cut on the rootstock, usually in late summer while the bark is still active.
Orchard
Whip and tongue
A bench grafting method in which matching sloping cuts, each with an interlocking tongue, hold scion and rootstock together while the union forms. Performed in late winter on dormant wood.
Fruit
Cultivar
A named clone propagated by grafting, so that every tree of it is genetically identical to the original seedling. "Variety" is used interchangeably in trade, though it has a stricter botanical meaning.
Orchard
Top working
Regrafting an established tree to a different cultivar by cutting back its main branches and grafting scions onto the stubs, keeping the existing root system and framework.
