Grafting bud is a horticultural technique used to join two plants together. It involves taking a bud from one plant and inserting it into the stem of another, usually related, plant. The bud will then grow and form a new branch on the receiving plant. The SCION is the part of the plant that is grafted onto the rootstock. It is usually taken from a mature plant and contains the desired characteristics of the plant, such as flower color or fruit size. Grafting bud is a common practice in commercial horticulture and is used to create new varieties of plants.
