Auxin Growth Hormone 1-Naphthyl Acetic Acid CAS No.86-87-3 98% TC
NAA is a broad-spectrum-based plant growth regulator, it can promote cell division and expansion, induce the formation of adventitious roots, scope for cereal crops, increase tillers, panicle rate and grain weight; reduce cotton ball falling, increasing fruit weight gain, improve quality. Promote flowering fruit trees, anti-fruit drop, ripening increase. Prevent fruits and vegetables from falling flowers, change female and male flowers ratio.NAA is a broad-spectrum-based plant growth regulator, it can promote cell division and expansion, induce the formation of adventitious roots, scope for cereal crops, increase tillers, panicle rate and grain weight; reduce cotton ball falling, increasing fruit weight gain, improve quality. Promote flowering fruit trees, anti-fruit drop, ripening increase. Prevent fruits and vegetables from falling flowers, change female and male flowers ratio.NAA is not soluble in water, we also has its sodium salt: sodium-NAA, it has the same effect with NAA and it is soluble in water.

NAA Physics and chemical properties:
White crystal or amorphous power, boiling point at 373.2℃, stable in property and incombustible, It can be dissolved in water and organic solvents. It is a kind low toxicity plant growth regulator. Acute oral LD50 for 1000-5900mg/kg, on the skin and mucous membranes have a stimulating effect.
Application:
1. Promote fruit and tuber enlarge quickly
2.To increase fruit-setting ratio
3.To promote formation of adventitious root and root
4.To promote plant grow quickly and stronger, increase output and improve quality
