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; on a branch the main stem of the branch is further dominant over its own side branchlets. Plant physiology describes apical dominance as the control exerted by the terminal bud (and shoot apex) over the ...

Term for the growth dominance or predominance of the shoot tips (apical = located at the tip, concerning the tip of an organ). The growth of the side shoots is suppressed by this. This phenomenon is controlled by the plant hormone auxin. This ensures that the uppermost eyes and shoots are preferably supplied with nutrients. The tendency of the...
