INDOLE-3-ACETIC ACID(IAA 99%)

IAA used as roots agent to make the roots develop and born;

Used to stimulate the tomatoes for Parthenocarpy and increasing the fruits setting: on the tomatoes flowering stage- spraying on flowers at 3000PPM for the Parthenocarpy and increasing the fruits settings.

Indole-3-acetic acid (IAA) is a plant hormone that belongs to the auxin class. It is a derivative of indole and is predominantly produced in cells of the apex and very young leaves of a plant . IAA has many different effects, such as inducing cell elongation and cell division with all subsequent results for plant growth and development. It is also a broad-spectrum plant growth regulator with indole activity that regulates the electron and proton channels of cell membranes.

3. Dosage and usages for plants:
(1). Used to stimulate the roots growth: at 100-1000PPM to dipping the cutting branches of vegetables or trees.

(2). At 10PPM to spraying on rice seedlings for rooting.

(3).The concentration of IAA may be between the range of 10-30ppm. The dosage and usage of IAA depend on the specific application and the type of plant. For example, IAA can be used for soaking flowers, inducing tomatoes and solidity and fruits, forming seedless tomatoes and fruiting.

(4).The most common method of applying IAA to plants is by foliar spraying. The recommended concentration of IAA for foliar spraying is at the concentration of 0.1 mg/L.

4. Mode of action:

IAA can stimulate and promote the division and elongation of cells, stimulate the tissues differentiation, enhance the development of RNA. Increase the penetration of cell membrane relax the cell wall, increase the flow of protoplasm.,

IAA can be utilized and absorbed through stems, leaf, roots. Stimulate the female flowers development. Promote the Differentiation of seeds, promote the fruits growth faster, increase the rate of fruits settings, make the leaf growth bigger, and wider, fasten the stems elongation, increase the differentiation of vascular bundle. activate the cambium, get concrescence of wound, prevent the flowers and fruits from dropping, stunt the appearance and growth of side branches, promote the germinate of seeds and roots growth.

5. Attentins:

(1). IAA can be broke down under sunlight, pls store under shadow, dry and cool place.

(2). Don’t mix with alkaline substances.
