What is the effect of indoleacetic acid, what is the effect of indoleacetic acid? What is the full E

At the organ and whole plant level, indoleacetic acid works from seedling to fruit ripening. Indoleacetic acid controlled the reversible red light inhibition of mesocotyl elongation in seedlings; When indoleacetic acid is transferred to the underside of the branch, the ground tropism of the branch is generated. When indoleacetic acid is transferred to the backlit side of the branch, the phototropism of the branch is generated.

Indoleacetic acid causes apical dominance; Delay leaf senescence; Indoleacetic acid applied to leaves inhibits shedding, while auxin applied to the proximal end of the separation promotes shedding. Indoleacetic acid promotes flowering, induces the development of parthenocarp and delays fruit ripening.

Problem description: What about indole butyric acid or phenylacetic acid??

Analysis: Indole-3-acetic acid Performance An endogenous auxin ubiquitous in plants, which is an indole compound.

Double-name growth, auxin, and heteroauxin. It is easy to decompose in light and air and is not resistant to storage. Safe for humans and animals.

Application Indoleacetic acid is broad-spectrum and multi-purpose, but it has become a commonly used commodity because it is easily degraded in and out of plants. In the early stage, it was used to induce parthenotopic fruit setting and fruit setting of tomatoes, and soaked flowers with 3000 milliliters of medicinal solution in the full flowering period to form seedless tomato fruits and improve fruit setting rate. Promoting the growth of cuttings is one of the earliest aspects of its application. Soaking the base of cuttings with 100 1000 milliliters of medicinal solution can promote the formation of adventitious roots of tea trees, gum trees, oak trees, metasequoia, pepper and other crops, and accelerate the vegetative reproduction rate.

1 10 mg of indoleacetic acid and 10 mg of caloxafen are mixed to promote the rooting of rice seedlings. 25 400 mg liters of liquid medicine sprayed once chrysanthemum (under a 9-hour photoperiod) can inhibit the appearance of flower buds and delay flowering. Growing in long sunlight, begonias are sprayed once at a concentration of 10 minus 5 molar liters, which can increase female flowers.

Treatment of beet seeds can promote germination, and lack of bends increases root yield and sugar content.

Indoleacetic acid and potassium indole butyrate are two different compounds. The differences between them are as follows:

1.Chemical formula: The chemical formula of indole acetic acid is C9H8O2, and the chemical formula of potassium indole butyrate is C13H11NO2K.

2.Molecular structure: indoleethyl nibuwild acid contains an indole ring and an acetate group; Potassium indole butyrate contains an indole ring, a butyrate group, and a potassium ion.

3.Physical properties: Indoleacetic acid is a white or light yellow solid, soluble in solvents such as water, acetone and ethanol; Potassium indole butyrate is a white or light yellow crystal that is easily soluble in water.

4.Uses: Indoleacetic acid is an alkaloid plant growth regulator, which can promote plant growth and fruit ripening; Potassium indole butyrate is also a plant growth regulator that promotes plant growth and fruit development, while also increasing crop yield and quality.

The chemical element composition of indoleacetic acid: it is composed of four elements: carbon, hydrogen, oxygen and nitrogen, and its structure is shown in the figure below

Indoleacetic acid is an organic substance. Pure products are colorless leaf-like crystals or crystalline powders. It turns rosy when exposed to light.

Melting Point: 165-166 (168-170). Soluble in anhydrous ethanol, ethyl acetate, dichloroethane, soluble in ether and acetone. Insoluble in benzene, toluene, gasoline and chloroform.

Insoluble in water, its aqueous solution can be decomposed by ultraviolet light, but stable to visible light. Its sodium salt and potassium salt are more stable than acid itself and are easily soluble in water. It is easily decarboxylated into 3-methylindole (skatosin).

It has duality to plant growth, and different parts of the plant have different sensitivities to it, and generally the root is larger than the bud and the stem. Different plants have different sensitivities to it.
