graft
graft
1. (noun) A small piece of tissue implanted into an intact organism.
2. (verb) To transfer a part of an organism from its normal position to another position on the same organism (autograft), or to a different organism of the same species (homograft), or an organism of a different species (heterograft). The source of the part that is grafted is called the donor (in animals) or the scion (in plants) and the organism to which it is united is called the host or recipient (in animals) or the stock (in plants). A graft hybrid is an organism made up of two genetically distinct tissues, owing to the fusion of host or scion and donor or stock after grafting. In cultivation a stem from one plant (the scion) is fused with a rooted portion of another (the stock) to form a single plant. Most fruit trees are produced by grafting, the type of fruit being determined by the scion, but the size of the tree by the stock.
