NEET BIOLOGY

Detailed explanation-1: -All plants naturally possess hormones, including the growth hormone auxin, which is produced in immature parts of the plant, where growth is necessary. Synthetic auxins are used in hormone rooting powders and gels to replicate natural growth conditions in plants, and encourage roots to form.

Detailed explanation-2: -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-3: -The rooting hormone works on a variety of cuttings, including new growth, woody stems, leaves, and roots to dramatically increase the odds of success with propagation. If the plant is a blooming plant, wait until the blooms fade before taking the cutting.

Detailed explanation-4: -Depending on the rooting hormone product, rooting occurs usually after 2 to 8 weeks. Before this rooting period is over it usually isn’t necessary to water plants as often as they would normally need during the rooting stage under normal conditions.

Detailed explanation-5: -Rooting compounds, being liquid or powders, when applied properly aid in rooting of moderate to difficult-to-root species, accelerate root initiation, improve rooting uniformity, increase the number of roots produced and ultimately reduce shrink and rooting time.
