In the process of grafting, the part that provides the root is called the stock, and the added piece is called the scion . This technique is used to attach the tissue of one plant to the tissue of another. In this process first, we have to make vertical incisions through the rootstock's bark and later we have to prepare scion, both scion and rootstock are jointed, and now it is called a graft. Grafting is one of the artificial methods of vegetative propagation.

A flower contains male and female reproductive parts. The male reproductive part of a flower is known as the stamen. It consists of an anther and filament. The oval-shaped structure called the anther contains pollen. The filament is a long stalk-like structure that attaches to the flower base and supports the anther.
