In grafting, the part of the plant that is grafted to the rootstock is known as what?

In grafting, the part of the plant that is grafted to the rootstock is referred to as the scion. The scion is a piece of a plant, typically containing a few buds, that is attached to the rootstock in order to propagate or enhance the desired traits of a particular cultivar or variety. This practice allows for the combination of the scion’s desirable qualities, such as fruit flavor or flower color, with the rootstock’s attributes, such as enhanced resistance to disease or improved adaptability to specific soil types.

Understanding the role of the scion in grafting is essential for successful propagation techniques. It is the portion that grows and develops into the upper part of the new plant, whereas the rootstock serves as the base of the plant, providing support and nutrients. This relationship can yield stronger plants that express the best features of both components, emphasizing the importance of choosing compatible scions and rootstocks for successful grafting outcomes.
