a method of vegetative propagation of plants in which a bud of a cultivated variety is grafted to wildling stock. A new plant develops from the bud. Budding is performed in nurseries usually in the summer (late July or early August for pome fruits, somewhat earlier for drupaceous plants).
one of the methods of asexual (vegetative) reproduction of animals and plants. Budding is the formation on the parent body of a bud—an outgrowth from which a new individual develops. Plants capable of budding include certain ascomycetes fungi (in yeasts, budding is the principal means of reproduction), a number of basidial fungi, and liverwort mosses (which reproduce by means of brood buds, or bulbels). Among animals, budding is characteristic of protozoans (some flagellates, infusorians, and sporozoans), sponges, coelenterates, some worms, bryozoans, pterobranchs, and tunicates.
Budding in animals may be external or internal. External budding may be parietal, with the buds forming on the parent body, or stolonate, with the buds developing on special processes known as stolons (some coelenterates and tunicates). With internal budding, the new individual develops from an isolated area inside the parent body. Examples are the gemmules of sponges and the statoblasts of bryozoans, which have protective membranes and serve mainly to ensure survival when the parent body perishes in the winter or during a drought. In a number of animals, the budding process remains incomplete and the young individuals remain attached to the parent body. As a result, there arise colonies made up of numerous individuals (colonial organisms). Sometimes budding is artificially induced by various influences, such as burns or cuts, on the parent body.
