The New International Encyclopædia/Vegetative Propagation

​VEGETATIVE PROPAGATION. The asexual process by which plants reproduce. Organs which assume this office are usually supplied with buds or they may develop them under favorable conditions. For instance, the tips of black raspberry canes develop new plants from the terminal and adjoining buds if these become covered with soil, and the roots of red raspberry develop buds when injured or when severed from the parent plant. Many creeping plants, such as strawberry and hen-and-chickens (Sempervivum), reproduce by means of rosettes, stolons, etc. The term brood bud or brood body is often employed to designate the initial buds in such propagation, and these are frequently employed in artificial propagation, as in layerage, graftage, and cuttage.
