Genetic variation in apical dominance
of Cedrela odorata seedlings in response to decapitation.
Even within a single species, plants vary in their tendency to express apical dominance
. Fuchsia cultivars 'Beacon Delight' and 'Blue Ribbon' express strong apical dominance
, so they're easier to train upright into miniature trees (called "standards") than are trailing cultivars, such as 'Basket Girl' and 'Blue Satin,' which have weak apical dominance
Can loss of apical dominance
in potato tuber serve as a marker of physiological age?

These processes include photoperiodism, shoot elongation, apical dominance
, shade avoidance, and root development.
Auxins have been found responsible for phototropism, geotropism, and apical dominance
Overcompensation has been reported for many plants where the principal mechanism appears to involve the removal of apical dominance
via herbivory of the shoot apical meristem, thus releasing lateral meristems and increasing the growth and fitness potential of the plant (Harris, 1974; Maschinski and Whitham, 1989; Aarssen and Irwin, 1991; Whitham et al., 1991).
asserted over lateral buds by the gall of Rhabdophaga strobiloides (Diptera: Cecidomyiidae).
A substantial body of experimental work has investigated the control of dormancy and apical dominance
in Marsilea (e.g., Chenou-Fleury, 1975; Sossountzov, 1976; Sossountzov & Chenou, 1978; Chenou et al., 1978, 1982; Habricot & Sossountzov, 1984a, 1984b; Sossountzov & Habricot, 1985; Sossountzov et al., 1985).
We discuss the possible role of apical dominance
in the interpretation of this correlation and compare genetic and environmental correlations.
