Definition: Adventitious roots are roots that occur on plant material other than the actual primary root of a plant. These roots take "advantage" of the plants ability to asexually create new roots where no tap root is present. These roots often grow from leaf and/or stem cuttings and can develop with or without the assistance of growth hormones. Adventitious plant buds can be attached to a variety of root stock via grafting.
Also Known As: Adventitiousness
Examples:Adventitious roots and buds are used by the horticulturist or plant propagator when producing new varieties of plants. They do this primarily through the use of cuttings of stem, leaf and root material.
