Grafting is a union of two related plants referred as stock & scion. The Stock or a Rootstock is wild, natural, vigorous, healthy, disease free, & the one with well-developed rooting system. The Scion is a high-quality, superior variety that possesses commercially &/or aesthetically desirable characters. In an ideal graft, roots & central main stem belong to stock, whereas all the growing branches, leaves, flowers & fruits belong to the scion.
