NAA synthetic plant hormones,
NAA 98% TC Plant Growth Hormone,
Naphthaleneacetic acid synthetic auxin
The hormone NAA does not occur naturally, and, like all auxins, is toxic to plants at high concentrations.
NAA is widely used in agriculture for various purposes. It is considered to be only slightly toxic but when at higher concentrations
it can be toxic to animals. This was shown when tested on rats via oral ingestion at 1000–5900 mg/kg.
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.
NAA present in the environment undergoes oxidation reactions with hydroxyl radicals and sulfate radicals.
Radical reactions of NAA were studied using pulse radiolysis technique. Hydroxyl adduct radical was formed as the intermediate during the
reaction of hydroxyl radical with NAA. The intermediate naphtyl methyl radical was formed during the reaction of sulfate radical anion with NAA.
In micropropagation of various plants, NAA is typically added to a medium containing nutrients essential to the plants' survival.
It is added to help induce root formation in various plant types.
It can also be applied by spraying it onto plants and which is typical in agricultural use.
It is prohibited in many areas to use it in high concentrations due to the health concerns towards humans and other animals.
