Here's a breakdown:
* Scion: The piece of branch that carries the desired apple variety. It contains the buds that will grow into the new apple-bearing branches.
* Rootstock: The established root system that provides nutrients and support to the scion. It is chosen for its specific qualities like disease resistance, dwarfing effect, or compatibility with the scion.
Why graft scions onto rootstocks?
* To propagate specific apple varieties: Grafting allows you to replicate a particular apple variety quickly and efficiently, preserving its unique characteristics.
* To control tree size: Rootstocks can influence the size of the mature apple tree. Dwarfing rootstocks are popular for home gardens, making it easier to manage the tree and harvest apples.
* To enhance disease resistance: Some rootstocks are resistant to certain diseases or pests, which can protect the entire apple tree.
In summary:
The scion is the genetic blueprint of the apple tree, carrying the traits of the desired apple variety. The rootstock provides the foundation for the tree, influencing its growth and resilience. Together, they form a successful apple tree.
