Indole 3 butyric acid IBA

Indole-3-butyric acid (IBA) is a plant growth hormone or plant auxin that plays a significant role in regulating various aspects of plant growth and development. It is a synthetic derivative of the naturally occurring auxin, indole-3-acetic acid (IAA).

IBA is commonly used in horticulture and agriculture for its rooting and growth-promoting effects on plants. Some of its key applications and effects include:

1. Rooting agent: IBA is widely used as a rooting hormone to stimulate root development in cuttings. When applied to the cut ends of stems or branches, it encourages the formation of new roots, which is crucial for successful propagation of many plants.

2. Adventitious root formation: IBA can induce the formation of adventitious roots, which are roots that emerge from non-root tissues like stems or leaves. This is beneficial for propagating plants vegetatively and establishing new plantlets.

3. Plant growth promotion: In addition to its root-inducing properties, IBA can also promote overall plant growth and development. It influences cell elongation and division, leading to enhanced shoot growth and branching.

4. Flowering and fruit setting: IBA can have an impact on flowering and fruit development in some plant species, resulting in increased flower formation and fruit set.

5. Stress responses: IBA can help plants cope with various environmental stresses, such as drought or high salinity, by modulating their physiological responses.
