Product Description
Indole-3-Acetic Acid (IAA) is the most important natural Plant Growth Regulator belonging to the auxin family. It plays a central role in regulating plant cell elongation, root initiation, vascular differentiation, and overall plant developmental processes.
IAA is widely used in agricultural research, tissue culture systems, and horticultural propagation. In commercial formulations, it is often combined with Rooting Agents, Foliar Fertilizers, Amino Acids, and Plant Extracts to enhance rooting efficiency and promote balanced plant growth.
Content Note: Prepared by our technical team based on current plant physiology literature. Agricultural claims comply with international regulatory guidelines. Last reviewed: April 2026
According to a study in Plant Physiology (2005), Indole-3-Acetic Acid is essential for regulating cell elongation and directional growth responses in higher plants.
A study published in Journal of Experimental Botany (2010) reported that auxin signaling pathways mediated by IAA significantly influence root development and plant architecture formation.

Indole-3-Acetic Acid is the foundational auxin in plant biology and is critical for understanding and regulating plant growth processes.
Buyer Insight: IAA is the most fundamental auxin in plant biology, but due to its instability, it is often replaced by more stable synthetic analogs in commercial agriculture.
It is a natural Plant Growth Regulator used to control plant growth, rooting, and development processes.
Yes, but mainly in research, tissue culture, and controlled horticultural applications due to its instability.
It is used in seedlings, tissue culture plants, and horticultural propagation systems.
It is applied in culture media, rooting solutions, or experimental foliar treatments.
Yes, we provide full OEM services including formulation, packaging, and regulatory documentation support.
