NAA represents Naphthalene Acetic Acid. These are also termed NAA auxin because it is a synthetic auxin. Thus these synthetic chemicals exhibit the activities of the natural plant hormone called auxin. This is mainly used for horticulture purposes. NAA is a colourless, odourless powder chemical that mimics natural auxin. NAA is sometimes considered harmful and toxic in higher concentrations but tends to provide positive effects when used in the right concentration. This is also named as 1-Naphthaleneacetic acid. α-Naphthaleneacetic acid, Naphthylacetic acid, Napthoxy acetic acid and 2-(1-Naphthyl)acetic acid. These are mixed with other chemicals and water in fixed proportions before application to the plants.

NAA can induce rooting, particularly vegetative propagation from the stem and leaf portions. They may also be of use during plant tissue culture. This is utilised in proper amounts to receive auxin-type results like cell division and development, to induce rooting, etc.
NAA cannot coexist in the presence of chemical substances such as oxidizers, chlorates nitrates, peroxides, sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, and epichlorohydrin.
