Which term is used for the part of a plant that provides nourishment contact during grafting?

The term used for the part of a plant that provides nourishment during grafting is the scion. In the grafting process, the scion is the upper part of the grafted plant that consists of the desired variety or cultivar. It is joined to the rootstock, which provides the root system and supports the grafted plant. The scion takes nutrients and water from the rootstock, facilitating the growth and development of the grafted plant.

The scion is crucial because it determines the characteristics, such as fruit quality or flower color. Successful grafting relies on the scion’s ability to integrate with the rootstock, allowing for the exchange of water, nutrients, and other essential compounds needed for the plant’s growth. Understanding the function of the scion is essential for anyone working with grafting techniques in horticulture or agriculture.
