Structural Formula

Function

Alginate oligosaccharide (AOS) has been proved to be an important signal molecule in plants, which can promote plant growth, improve plant resistance to disease, enhance their ability to adapt to the environment, and improve crop yield and quality.

Function Characteristics

Promote plant growth

Alginate oligosaccharide can participate in the regulation of plant growth as a signal molecule, break seed dormancy, promote germination and root growth; improve the chlorophyll content in seedlings, enhance photosynthesis, promote seedling growth, and significantly increase the content of hormone (indoleacetic acid, etc.).It can also stimulate auxin-related gene expression by promoting hormone content, lipase, amylase and protease, promote the growth of plant root and stem and protect fruit, promote fruit ripening, and improve crop yield and quality.

2.Improve disease resistance

It can activate the innate immune system of plants, regulate the defense genes in plants, improve the disease resistance of plants, prevent the occurrence of diseases, with wide spectrum and high efficiency.

3.Improve the stress resistance

Abscisic acid is a very important growth hormone in plants and plays an important role in dealing with stress. The application of agricultural grade algal oligosaccharides can induce the secretion of abscisic acid in plants. The results show that agricultural-grade alginate oligosaccharide can induce the accumulation of abscisic acid in plants, reaching 5-7 times higher than the normal level, thus improving the stress resistance. In addition, agricultural grade alginate oligosaccharides can also improve the content of soluble sugars and free proline in plants, enhance the activity of plant antioxidant enzymes, induce the synthesis of phytoalexin, reduce the permeability of cell membrane and malondialdehyde content, so as to improve plant stress resistance.

4.Promote plant nutrient absorption

The alginate oligosaccharide can combine ammonium ions in nitrogen fertilizer to form complex, thus inhibiting the conversion of ammonium nitrogen (NH4 +) to nitrate nitrogen (NO3-), reduce nitrogen loss and provide nutrients for long-term, promoting the absorption of N, P, Ca, Mg, Mn, B, Zn and other elements.

Natural preservative

Alginate oligosaccharide is a natural preservative that can extend the shelf life of fruits.

Storage

Store in sealed container, place in a cool dry place
