Constitutional formula:
Molecular formula:
C12H10O2
Physics and chemical character:
White crystal or amorphous power, boiling point at 265.5℃, stable in property and incombustible ,high purity sodium a-naphthaleneacitic acid can be dissolved in water and organic solvents such as benzene, acetone ,ether and alcohol, which can be prepared into water aqua, emulsion oil and powder types ,overcoming the shortcoming of ordinary a-naphthaleneacitic acid being only soluble in organic solvents .It is simple to use and can be prepared at any concentrations. High purity sodium a-naphthaleneacitic acid has no toxic and side effects on plants while ordinary sodium a-naphthaleneacitic acid contains some harmful substances. These substances are coupled macromolecules, and easily cause scorching spots on plant sprouts ,stems ,leaves ,blooms and fruits, affecting normal growth and development in plants and even causing plants to die at high concentrations.
Mechanism of action:
High purity sodium a-naphthaleneacitic acid,a somatotrophin-like growth regulator in plants ,enters plants via leaf and branch cuticles and seeds ,and flows to luxuriant growth sites (growth points ,tender organs, blooms or fruits ) with nutrients .It can produce significant effents in promoting development of pointed ends for the root system, resulting in more ,straighter and thicker roots.
Physiologically ,it can rapidly promote cellular division and enlargement ,leading to the formation of adventitious roots (root taking agents) .It can induce blossom, avoid flower and fruit dropping .resulting in seedless fruit formation ,promote early maturity and increase production, Also, it can enhance plantsĄŻ ability to resist drought ,cold ,disease ,saline and alkali, and dry hot wind .Experiments conducted in Japan and Taiwan have shown that high purity sodium a-naphthaleneacitic acid performs much better than ordinary sodium a-naphthaleneacitic acid in terms of efficacy.
