budding
1. The formation of buds as a result of cell division in a localized area of a shoot. In general, budding is promoted by cytokinins and is inhibited by auxins.

2. The grafting of a bud on to a plant.

3. Gemmation, a form of asexual reproduction in which a new individual develops within the body wall or cell membrane of the parent, causing a bud-like swelling, then detaches itself to commence an independent life. In certain single-celled micro-organisms a new cell is formed by extrusion or out-growth from an existing cell. See also ASEXUAL REPRODUCTION.
