Product Description
NAA Powder (Naphthaleneacetic Acid) is a widely used Plant Growth Regulator belonging to the synthetic auxin family. It is applied in modern agriculture to regulate plant growth processes such as rooting, fruit thinning, fruit set control, and yield optimization.
NAA is extensively used in fruit orchards, vegetable cultivation, nursery propagation, and horticultural production systems. It is commonly formulated with Foliar Fertilizers, Amino Acids, and Plant Extracts to enhance crop performance, improve fruit quality, and support balanced vegetative and reproductive growth.
Content Note: Prepared by our technical team based on current agronomic literature. Agricultural claims comply with international regulatory guidelines. Last reviewed: April 2026
According to a study in Plant Growth Regulation (2005), Naphthaleneacetic Acid significantly influences rooting formation and fruit thinning efficiency in commercial fruit crops.
A study published in HortScience (2010) indicates that auxin-based regulators like NAA improve transplant survival rate and enhance root system development in horticultural propagation systems.
