grafting

Explanation:

Grafting is a method used for the creation of grafts, which are instruments used in a type of asexual reproduction for the propagation of difficult root plants. This method is done by plant specialists (such as botanists or agronomists) and consists of the union of two different species. The process takes place between a part of a plant called a graft (or rider) that is inserted into another part of another plant (or another individual of the same species), which may be the root system or the stem known as a rootstock (or horse)
