Description

3-Indoleacetic acid (IAA) is a fundamental plant hormone of the auxin class, critical for regulating growth and developmental processes. Its high purity and consistent quality are essential for reliable research and commercial applications in plant science and agriculture. This compound is primarily utilized by researchers in plant physiology, biotechnologists, and manufacturers of plant growth regulators and tissue culture media.

Application

• Plant Tissue Culture: A key component in media formulations to induce cell division, root initiation, and callus growth.
• Agricultural Research: Used in studies on tropisms, apical dominance, fruit development, and leaf abscission.
• Plant Growth Regulator (PGR) Formulation: Serves as an active ingredient in commercial products designed to promote rooting of cuttings and enhance crop yield.
• Biochemical Research: Employed as a standard in analytical methods (e.g., HPLC, ELISA) for quantifying endogenous auxin levels in plant tissues.
• Seed Treatment: Applied to improve germination rates and early seedling vigor under stress conditions.
• Micropropagation: Essential for the large-scale cloning of elite plant varieties in sterile laboratory conditions.
