Description:

Indole-3-Butyric Acid is a plant hormone in the auxin family, widely used in agriculture and horticulture to stimulate root growth in plant cuttings.

Biological Function

• Indole-3-Butyric Acid is a synthetic auxin, mimicking indole-3-acetic acid (IAA), the natural auxin.

• Promotes adventitious root formation, especially in cuttings and tissue culture.

• Less sensitive to enzymatic degradation than IAA, making it more stable and effective over time.

Applications

• Used in rooting powders, gels, or solutions.

• Applied to cut stems or leaves to enhance root initiation.
