Out of the proper or usual place; as, adventitious buds or roots.
buds or roots that develop in unusual areas. Many wetland plants exhibit adventitious roots.
Description of structures that are abnormal in their position of formation (e.g. roots forming from stems). Organs that take advantage of opportunities for development.
applied to roots, those which do not arise from the radicle but from another part of the plant, usually the stem.
Organ or structure in an unusual place such as roots growing from the stem
A structure arising at sites other than the usual ones, e.g. shoots from roots or leaves, and embryos from any cell other than a zygote.
A plant organ (such as a bud, shoot, or root) produced in an abnormal position or at an unusual time of development.
Roots which grow in unusual places, such as wherever the stem of the plant comes in contact with the ground.
(Shoot or root) arising on stem, bole or boughs. Parent Term: Tree_bole Difficulty Level
Produced in an unusual position or time; can refer to any plant organ (bud, root, shoot).
In an unusual or unexpected place.
concerns a shoot or root produced on an uncommon place such as a root on a branch.
Adventuring. Occurring in an abnormal or unusual position, such as a root.
roots or stems arising from unexpected locations
Growing from an unusual position.
Adventitious organs are those organs that grow from an unusual part of the plant. For example, fibrous adventitious roots grow from the trunk above the ground instead of starting underground.
Not in the usual place (buds that have remained undeveloped so that they are no longer evidently axillary, or that really originate elsewhere, as on a root).
arising in abnormal positions, e.g. roots arising from the shoot system, buds arising elsewhere than in axils of leaves.
Buds or roots that develop without pattern.
Developing from unusual points of origin, such as shoots or root tissues from callus or embryos from sources other than zygotes. This term can also be used to describe agents which contaminate cell cultures.
Adventitious, in botany, refers to structures that develop in an unusual place, and in medicine, it refers to conditions acquired after birth. This article discusses adventitious roots, buds and shoots, that are very common in vascular plants.
