Abstract. The term apical dominance refers to the inhibition of growth of subtending lateral (axillary) buds by a growing shoot apex. Some degree of apical dominance is found in all seed plants, and the phenomenon obviously is of profound significance in determining growth form.


21 nov. 2020 — dominant leader because of apical bud death or free growth of lat-. eral buds on the When one shoot takes over apical dominance, the.

AVAILABILITY Windsor and Santa Rosa pubs only (no distribution), draft and bottles, limited-release Apical dominance is the control exerted by the apical portions of the shoot over the outgrowth of the lateral buds. The classical explanations for correlative inhibition have focused on hormone/nutrient hypotheses. The remarkable progress that has been made in the technology of endogenous hormone quantification in plant tissue has not been accompanied by comparable progress in the elucidation of mechanisms of hormone action in apical dominance. Apical dominance is thought to be caused by the apical bud producing IAA (auxin) in abundance.

apical dominance A condition in plants where the stem apex prevents the development of lateral branches near the apex. It is controlled by auxins produced at the apical bud. Close to the bud, the auxin concentration is high and inhibits lateral growth; further back, the concentration is lower and branching occurs. Apical dominance is a phenomenon in which central stem is dominant and lateral stems are suppressed.

Apical dominance

"Apical Dominance is the phenomenon where the strongest central stem of a plant, or in this case a hop bine, becomes dominant over the other stems. This beer is a lager brewed with one of our favorite new experimental hop varieties, HBC-692, which contributes notes of pink grapefruit and sage." Came out of years of hibernation for this review. The tendency for suppression of the lateral bud break is referred to as the apical dominance of the terminal bud. This young growing point or terminal bud is the site of manufacture of the class of plant hormones known as auxins.

Occasionally, strong apical dominance is advantageous, as in the "Ballerina" apple trees. Apical Dominance ROOTSTOCKS | Scion–Rootstock Relationships. Apical dominance means that the growing apex of a plant controls the Crop Systems.

Abstract: In young plants of  of hormone action in apical dominance. Evidence from hormonal studies suggests that apically produced auxin indirectly suppresses axillary bud outgrowth that  Apical dominance (AD) and apical control (AC) are thought to be important control mechanisms in this developmental response.

Apical dominance definition is - inhibition of the growth of lateral buds by the terminal bud of a shoot.

2021-03-08 · For almost a century, auxin had been well-known as the master regulator of apical dominance. Recently, however, sugars were shown to be the initial regulator of apical dominance, while strigolactones (SLs) and cytokinins (CKs) act downstream of auxin to control bud outgrowth. However, the interactions of the different pathways have remained outstanding questions.
