Grafting is a horticulture technique where the living detached portion of the plant are used to regenerate the growth. One plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion.
Bud grafting is commonly used in rose plants. It is also known as chip budding. In this technique, bud acts as a scion. The bud removed from the parent plant are inserted beneath the bark of the stem of the stock plant from which the rest of the shoot has been cut. T cut is made in the stock in which the bud is inserted. The bud develops into a new twig.
