Description and Uses
1-naphthaleneacetic acid (NAA), also known as α-naphthaleneacetic acid, belongs to a class of organic compounds of naphthalenes, which contain a naphthalene moiety of two fused benzene rings. NAA is a synthetic auxin plant hormone. It is used as a plant growth regulator to control preharvest fruit drop, flower induction and fruit thinning in various crops such as apples, potatoes, olives, and citrus fruits. It is used as a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture and as herbicide. Applied as a dust or spray it delays dissolution of the abscission layer, retarding the fruit drop. The effect of NAA on plant growth is greatly dependent on the time of admission and concentration. When used after four weeks, NAA stimulates shoot growth, while full-time use limits growth. When used in a 4-week pulse, adventitious root growth is greatly increased.
1-Naphthaleneacetic acid is widely employed in agriculture as a synthetic plant hormone in the auxin family or a plant growth regulator, which can find applications in tissue culture. Inducing rooting of plant cuttings, spraying apple trees to prevent early drop, fruit thinner.
1-Naphthaleneacetic acid has been used:
to modify MS media for the initiation of callus
as a supplement in solid K3 medium for the selection of transformants
in the preparation of culture medium like V-KM medium and Cg medium
