Detailed explanation-1: -The upper part of the graft (the scion) becomes the top of the plant, the lower portion (the understock) becomes the root system or part of the trunk.

Detailed explanation-2: -The rootstock is the lower portion of the grafted plant, the part that produces its roots. “Understock” and “stock” are synonyms for “rootstock.” Usually, the top of the rootstock is about at the soil line, but not always! When plants are “top worked, ” they might be grafted at a point many feet above the ground.

Detailed explanation-3: -During grafting, the portion of plant that is grafted is called scion.

Detailed explanation-4: -The rootstock is the root system of a tree with a part of the stem. Onto this, the flowering or fruiting part of another tree (called the scion) is grafted. This is then grown as a whole new tree. Many trees can be grafted onto the same rootstock.

Detailed explanation-5: -In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another.
