Rootstock
Rootstock
Rootstock (pronunciation: /ˈruːtˌstɒk/), also known as stock, is a plant or plant part, typically a stem or rhizome, onto which another plant (the scion) is grafted. It forms the root system of the grafted plant.
Etymology
The term "rootstock" originates from the Middle English words "rote" and "stock", which mean root and stem, respectively.
Description
A rootstock is used in grafting to provide a robust and disease-resistant root system for the scion. The scion is the part of the plant that is selected for its flowers, fruit, or foliage. The rootstock and scion maintain their genetic identity, but the scion benefits from the rootstock's root system.
Rootstocks are selected for their ability to absorb water and nutrients, resist pests and diseases, and adapt to soil conditions. They are used extensively in agriculture and horticulture, particularly in the production of fruit trees and roses.
