What are Rootstock and Scion?
Feb 10, 2020

Grafting is one of the methods of artificial propagation of plants, and it is a technique that vegetatively joins two plants into one. Instead of cross-pollinating two plants and producing hybrid seeds, grafted plants use root (rootstock) of one plant to attach to branch (scion) of another. Grafting is performed by using the healing function of plants after injury.


Rootstock


What is a rootstock?

The lower plant part used in grafting is called the rootstock. This is usually a healthy root system and some part of the stem. The characteristics of the rootstock can make plants grow faster.


What is a scion?

The part above the graft is called the scion. It is a young shoot or bud from a plant with beneficial characteristics like great flavor, color, or disease resistance. All of the top growth of a grafted plant, leaves, flowers, fruits, etc., comes from the scion. By combining rootstock and scion, you can be reasonably assured you will wind up with a reliably hardy and productive plant. The rootstock and scion do not have to be from the same species, but they should be closely related.
