The plant that grows after grafting is the scion's plant; the key to grafting is to have the scion's formative layer close to the rootstock's formative layer.

The process of transferring a branch or bud of a superior variety to a common plant and allowing it to survive to form a plant of superior quality is called grafting. The branch of the superior variety is called the scion and the plant that receives the scion is called the rootstock. The main purpose of grafting is to maintain the characteristics of the superior plant variety, advance flowering, etc.

Expanded Information:

When grafting, the formation layers of the two wounded surfaces are brought close together and tied tightly, and the result is that, due to the proliferation of cells, the cells heal with each other to become vascular tissues joined together as A whole. This is the principle of grafting.

The main factor affecting the success of grafting is the affinity of the scion and rootstock, followed by grafting technology and post-grafting management. The so-called affinity is the scion and rootstock in the internal tissue structure, physiological and genetic.
