Domination and control of meristematic leaves or buds located on the lower stem, roots, or rhizomes by hormones produced by apical meristems located on the tips and upper branches of plants, particularly woody plants.
The influence exerted by a terminal bud to suppress growth of lateral buds.
The tendency for a plant's apical meristem to be more active than its lateral or axial meristems. It is particularly evident in young trees, and is due to production of auxins in the apical meristem.
the inhibition of growth of side buds by the shoot tip
Apical dominance is the phenomenon in which a terminal (end) bud inhibits the development of lateral (side) buds.
the upward growth of terminal shoot meristem(s) at the expense of lateral shoots below whose development they inhibit
the inhibition of the development of the lateral buds by hormones.
(â´-pì-kel) - The tendency of an apical bud to produce hormones that suppress growth of the buds below it on the stem.
Controlling influence of the apical bud over the growth of a stem, which restricts the development of lateral buds. If the tip is removed apical dominance is broken, and lateral shoots below will grow more vigorously, competing to become the new leader.
In plant physiology, apical dominance is the phenomenon whereby the main central stem of the plant is dominant over (i.e., grows more strongly than) other side stems, and on a branch, the main stem of the branch is further dominant over its own side branchlets.
