Detailed explanation-1: -Mostly all the cells producing auxin are situated in the apical meristem in the stem. There, this hormone inhibits the growth of lateral buds, and this phenomenon is called ‘apical dominance’. Additional information: Auxins are also responsible for root growth, wilting of leaves, and fruit development.

Detailed explanation-2: -Generally, there are five types of plant hormones, namely, auxin, gibberellins (GAs), cytokinins, abscisic acid (ABA) and ethylene. In addition to these, there are more derivative compounds, both natural and synthetic, which also act as plant growth regulators.

Detailed explanation-3: -Used in high doses, auxin stimulates the production of ethylene, also a native plant hormone.
