Physiology of Plant Growth and Development
Adventitious Growth

Adventitious structures are those that grow in atypical locations. For instance, adventitious roots and buds can form in a variety of situations As a result of the resumption of meristematic activity in certain Cells. Adventitious, or accessory, roots develop independently of the primary ROOT and form the main root system in monocots, originating from nodes on the stem. Rhizomes and stolons are stem structures from which adventitious roots grow directly. Such adventitious roots play a crucial role in plant propagation by cuttings. Ivy, for example, uses adventitious roots to cling to substrates. Adventitious buds also occur, developing on roots, shoots, and leaves. For instance, African violets can be propagated from leaves that form adventitious buds and roots. In trees, new branches can develop from adventitious buds that form on the trunks.
