Description

3-Indoleacetic Acid Potassium Salt is the potassium salt form of the essential plant hormone indole-3-acetic acid (IAA). This formulation offers enhanced stability and solubility in aqueous systems compared to the free acid, making it a critical component for advanced plant tissue culture and agricultural research. It is primarily utilized by biotechnology firms, agricultural research institutions, and manufacturers of plant growth regulators to study and manipulate plant developmental processes such as cell elongation, root initiation, and tropic responses.

Application

• Plant Tissue Culture Media: A key auxin source for inducing callus formation, somatic embryogenesis, and root differentiation in sterile culture systems.
• Agricultural Research & Development: Used in experimental protocols to study plant physiology, hormone signaling pathways, and stress responses.
• Plant Growth Regulator (PGR) Formulations: Serves as a stable active ingredient in the production of specialized PGRs for horticulture and viticulture.
• Seed Treatment Solutions: Incorporated into treatments to potentially enhance germination vigor and early root system development.
• Hydroponic and Aquaponic Nutrient Systems: Provides a bioavailable auxin source in soilless cultivation setups to promote root health and plant architecture.
• Biostimulant Production: Used in the development of advanced biostimulant products aimed at improving crop yield and resilience.
