Product Description
Naphthaleneacetic Acid (NAA) Powder is a widely used Plant Growth Regulator belonging to the synthetic auxin family. It plays a key role in regulating plant growth processes such as rooting, fruit thinning, flower and fruit retention, and overall crop development balance.
In modern agriculture, NAA Powder is extensively applied in fruit orchards, horticultural crops, and vegetable production systems. It is commonly formulated with Foliar Fertilizers, Growth Promoters, and Plant Extracts to optimize yield, improve crop uniformity, and enhance stress resistance in plants.

According to a study in Plant Growth Regulation (2005), Naphthaleneacetic Acid significantly influences fruit thinning and improves fruit size uniformity in apple and pear orchards.
A study published in HortScience (2010) suggests that auxin analogues such as NAA may enhance rooting response and improve transplant establishment in horticultural crops.
