Description:
1-Naphthalene acetic acid is a white crystallization, odorless and tasteless, with a melting point of 130℃. It is soluble in acetone, ethyl ether, benzene, ethanol, chloroform and other organic solvents, but almost insoluble in cold water. The solubility in water at 20℃ is 0.024g/100g, soluble in hot water. 80% naphthalene acetic acid original powder is a light yellow powder, melting point 106-120℃, moisture content ≤5%, stored at room temperature, the content of effective components change little. Naphthalene acetic acid encounters alkali to be able to become salt, salt kind can dissolve in water, when this makes up medicaments solution, often dissolve in ammonia water hind dilute use again. Acute oral administration of LD50 in mice was 1456 mg/kg (male), 843 mg/kg (female), carp LC50(48 h)>40 mg/l, naphthalene acetic acid had stimulation effect on skin and mucosa.
1-Naphthalene acetic acid can enter into the plant through the young epidermis and seeds of leaves and branches, and then transfer nutrients to the active sites, stimulate cell division and tissue differentiation, induce monogamous fruiting, form seedless fruits, and promote flowering. Cellulase was inhibited in a certain concentration range to prevent falling flowers, fruits and leaves. It induces the formation of adventitious roots of branches and accelerates the cutting rooting of trees. The low concentration promotes the growth and development of plants, while the high concentration causes the production of endogenous ethylene, which can accelerate the ripening and increase the yield, and also improve the resistance of some crops to cold, drought, waterlogging and salt.
