How do roots take part in vegetative propagation?

Answer 1

• Vegetative propagation or vegetative reproduction is the process of multiplication in which a portion of a fragment of the plant body functions as propagates and develops into a new individual. Some plants are able to multiply by vegetative methods, which involve the production of new plants without the act of fertilization or sexual union.

• Asexual or vegetative propagation of plants is that form of plant propagation in which the new individual arises from any vegetative part of the parent (root, stem, leaf, etc.), and possesses exactly the same characteristics of the parent plant from which it was sampled. Plants may be propagated artificially by vegetative means by working on natural principles. A. Vegetative propagation by roots: The roots of some plants develop adventitious buds on them e.g., Dalbergia sissoo (Shisham), Guava, poplars, Albizzia lebbek, Murraya, etc. Some tuberous adventitious roots besides possessing adventitious buds also contain sufficient quantities of, food, e.g., Dahlia and Sweet potato.
