Shedding of mature leaves from the stem or ripe fruits from the stem is called abscission. Generally a layer of tissue is formed at the base of the organ. For, example, at the base of petiole in mature leaves of deciduous trees. This layer of tissue is called abscission zone.

It has been shown that abscission zone does not occurs when the concentration of auxin is high.
