White Naphthalene Acetic Acid Powder, For Industrial, Purity : 99%

NAA (a synthetic auxin) is used in many commercial rooting products. It is used to promote rooting from stem and leaf cuttings. NAA is also used in plant tissue culture work.

NAA has been shown to greatly increase cellulose fiber formation in plants when paired with another phytohormone called gibberellic acid. Because it is in the auxin family it has also been understood to prevent premature dropping and thinning of fruits from stems. It is applied after blossom fertilization. Increased amounts can actually have negative effects however, and cause growth inhibition to the development of plant crops. It has been used on many different crops including apples, olives, oranges, potatoes, and various other hanging fruits. In order for it to obtain its desired effects it must be applied in concentrations ranging from 20–100 μg/mL.
