Other Names: a-naphthlcetic acid, NAA

MF: C12H10O2

Physics and chemical properties:

Naphthalene acetic acid is white crystal or amorphous powder, melting point is 130°C, boiling point is 265.5 °C.

It can be dissolved in heat water and acetone, diethyl ether, benzene, alcohol, chloroform and other organic solvents. It is a kind of low toxicity plant growth regulator. Acute oral LD50 for 1000-5900 mg/kg, on the skin and mucous membranes have a stimulating effect.

Function:

1. NAA is a broad-spectrum-based plant growth regulator, it can promote cell division and expansion.

2. It is suitble for cereal crops, increase tillering, improve the percentage of panicle rate and grain weight.

3. Reduce cotton ball falling, increase fruits weight, and improve the quality.

4. Promote fruit trees flowering, prevent the fruit falling off, and promote early-maturing and increase production.

5. Prevent fruits and vegetables from falling flowers, change female and male flowers ratio.

6. Promote cutting branches rooting.
