Detailed explanation-1: -Which hormone is used to increase rooting? These commercially available products typically contain indole-3-butyric acid (IBA), a chemical form of the plant hormone auxin. Naphthalene acetic acid (NAA) is a synthetic rooting hormone that also helps prevent rotting. Both of these chemicals help stimulate root growth.

Detailed explanation-2: -Synthetic auxins include 2, 4-D (2, 4-Dichlorophenoxy Acetic acid), Indole-3-Propionic Acid, alpha-Naphthalene Acetic Acid (NAA), and 2, 4, 5-T (2, 4, 5-Trichlorophenoxy Acetic acid).

Detailed explanation-3: -Auxins promote root initiation and induce growth of pre-existing roots as well as adventitious roots. In horticulture, auxins, especially NAA and IBA, are commonly applied to stimulate root initiation in woody plants.

Detailed explanation-4: -Auxins are one specific group of hormones that are used: as rooting powders.

Detailed explanation-5: -What Does Synthetic Rooting Hormone Mean? A synthetic rooting hormone is a synthesized, man-made form of a plant’s natural hormone indoleacetic acid (IAA), also referred to as auxin. The synthetic auxin hormone stimulates root growth in plants.
