Question

What is a rootstock?                                   

Answer 1

A rootstock is the root or lower portion of a plant used for grafting or budding another plant, known as the scion. The rootstock provides the root system for the grafted plant, which can improve its resistance to disease, pests, or environmental stress and change its growth characteristics. Rootstocks are commonly used for fruit trees, grape vines, and roses, among other plants.

Answer 2

A rootstock is a part of a plant, typically the lower stem or roots, onto which a scion (the desired plant variety) is grafted. It provides the root system and sometimes also affects the plant's growth characteristics and disease resistance.
