Question

Which hormone reverses the apical dominance effects?

Answer 1

Apical dominance is a phenomena that occurs in plants when plant growth regulators are secreted improperly. In this case, the primary axis of the shoot is harmed because it grows faster than the rest of the plant.
When the apical buds dominate and limit the growth of the lateral axillary buds, this is known as apical dominance. The plant becomes long and lanky as a result of this.

Complete answer:
Apical dominance is known to be regulated by hormones like cytokinins and auxins.
When the apical buds dominate and limit the growth of the lateral axillary buds, this is known as apical dominance. The plant becomes long and lanky as a result of this. As a result of the lack of a solid stem to support its length, the plant bends. Auxin, which is released from the shoot tip, is responsible for this process.
Decapitation, or the removal of the shoot tips of such plants, can prevent apical dominance. This approach is applied in tea plantations and hedge-making because additional leaves result from the formation of lateral buds.
Because the relative ratio of auxin and cytokinin controls the level of apical dominance, cytokinin is employed to break the effects of apical dominance.
Apical growth is defined as a longitudinal rise at the central stem's tip. The lateral stems are subordinate to the primary stem. The lateral stems, on the other hand, are kept under control. This is caused by a plant hormone present in the apex of the central shoot's tip.

Note:
The substance indole-acetic acid (IAA) and other natural and synthetic compounds that are related to it are referred to as auxin.
Auxin, which is produced in our liver, was initially identified from human urine.
Because the relative ratio of auxin and cytokinin controls the level of apical dominance, cytokinin is employed to break the effects of apical dominance.
