apical dominance

They are known to regulate axillary bud growth and apical dominance.

The tree's habit is conical, with a pronounced apical dominance.

The mechanism of apical dominance is based on the plant hormone auxin.

Consider, for example, apical dominance, or the tendency of the uppermost shoots on any plant to be the strongest.

Occasionally, strong apical dominance is advantageous, as in the "Ballerina" apple trees.

Apical dominance is therefore most likely adaptive.

It was first discovered that the plant hormone auxin likely regulates apical dominance in 1934.

Some fruit trees have strong apical dominance, and young trees can become "leggy", with poor side limb development.

And stems may turn upward of their own accord in an attempt to gain apical dominance over other stems.

Apical dominance is phenomenon where one meristem prevents or inhibits the growth of other meristems.

Recent investigations into apical dominance and the control of branching have revealed a new plant hormone family termed strigolactones.

It induces shoot apical dominance; the axillary buds are inhibited by auxin.

It often includes elongation, altered flowering time, increased apical dominance and altered partitioning of resources.

Apical dominance occurs when the shoot apex prevents the growth of lateral buds so that the plant may grow vertically.

The principle of apical dominance is manipulated for espalier creation, hedge building, or artistic sculptures called topiary.

The decurrent habit is characterized by having weak apical dominance that eventually produces a rounded or spreading tree crown.

Cutting the top bud back to the height of the fence released the remaining buds from the suppressing effect of apical dominance.

Because of their horizontal orientation, the arms exhibit little apical dominance from their tips so buds farther down can develop side branches.

The typical form is a compact mass of closely spaced stems with minimal apical dominance that terminate in individual rosettes.

This causes lower limbs to grow more rapidly while the pinched tissue heals, after which time the stem resumes apical dominance.

Additionally, it may also lead to leaf-tip and bud necrosis in some cases, which often leads to loss of apical dominance in the shoots.

Choosing upright shoots ensures apical dominance and upward growth and reduces the possibility of the tree growing laterally like a bush.

Young trees show strong apical dominance with a straight trunk and symmetrical conical crown, becoming rounded to irregular on old trees.

P. fortunei generally displays better apical dominance than other Paulownia species along with greater adaptability to a wide range of soil types and climates.

Reiterations are identified by an upturned branch that had gained apical dominance and formed an additional branch supporting trunk.
