Indole-3-acetic acid (IAA, CAS#87-51-4) is a natural plant auxin primarily utilized in agriculture to stimulate root growth in cuttings, extend the shelf life of flowers and fruits, and regulate plant growth and fruit development. Additionally, it plays a key role in horticultural tissue culture, plant stress resistance management, and research into plant physiological mechanisms. It is important to control the application concentration to prevent inhibiting plant growth.
