Alginate oligosaccharides 90% Powder
Product name:Alginate oligosaccharides
Chemical name:
CAS number:16521-38-3
Molecular formula:(C6H7NaO6)n
Structural formula:
Properties: Light yellow brown powder, soluble in water, with strong stability.
Alginate binds to 1,4-glycosidic bonds α- L-glucuronic acid( α- L-gluronicacid (G) and β- D-mannuronic acid( β- D-mannuronic acid (M) is connected to form polymerized long chains, so there are mainly three ways of combining alginate: a polymer composed only of M β- D-mannuronate fragment (PM), a polymer composed only of G α- L-glucuronic acid fragments (PG), as well as copolymers composed of G and M (Heteropolymer, PolyMG). M and G, which make up alginate, are structurally opposite isomers of each other, mainly with different carboxyl positions at the C5 position, and the ratio of M and G is closely related to their biological activity.
Mechanism of action:
Alginate oligosaccharides, as plant immune activators, can stimulate and induce the synthesis of endogenous hormones (IAA, ABA, GA, jasmonic acid, etc.) in plants 5-8 times, promoting root growth and also achieving drought, cold, salt, and disease resistance
Main use:
1. Improve plant resistance
Brown algae oligosaccharides can promote the growth and repair of plant cell walls, increasing plant resistance. At the same time, it can also activate the internal defense mechanisms of plants, enhance their resistance to pathogens and viruses, and thereby improve their growth ability and yield.
2. Promote plant growth
Brown algae oligosaccharides contain various plant growth hormones, which can promote plant growth and development. It can activate the metabolism of plant cells, increase their photosynthetic capacity, and promote the growth of plant roots, increasing their ability to absorb water and nutrients.
3. Increase production
By promoting plant growth and enhancing plant resistance, brown algae oligosaccharides can significantly increase plant yield. Meanwhile, brown algae oligosaccharides can improve the nutrient absorption capacity of plants, reduce the use of pesticides and fertilizers, and reduce environmental pollution.
Dosage of application:
The early stage of crop production promotes rooting and strong seedlings, while the later stage of crop growth significantly increases yield. Initial usage: 150 grams per hectare, mixed with bacterial solution or amino acid infusion. 150 grams per hectare in the later stage, with 1-2 leaf sprays.
Quality standard:
Other information about the product:
A study has found that Alginate oligosaccharides have a promoting effect on the growth of barley roots, with a more significant effect on the embryonic roots. Within 2-4 hours of contact with Alginate oligosaccharides, the embryonic roots will experience a promoting effect. The germination rate of pea seeds soaked in alginate oligosaccharides increased, and the height, root length, and biomass of the seedlings all increased. The chlorophyll content in the leaves of the seedlings increased, and the vitality of the roots was enhanced. The effect of low concentration was obvious. In 2009, Le's research results showed that 1-3 k of alginate oligosaccharides had a strong promoting effect on the growth and development of soybeans and barley, and it was speculated that alginate oligosaccharides with an average molecular weight of 1-3 k were stimulating factors for plant growth and development.
As an endogenous plant oligosaccharide, alginate oligosaccharides play a signaling role in plant stress response. Research has shown that a 0.20% solution of alginate oligosaccharides can reduce electrolyte leakage and malondialdehyde content in tomato seedlings, increase the content of abscisic acid and total soluble sugars, and enhance the activity of antioxidant enzymes. These changes are all manifestations of the enhanced drought resistance of tomatoes, indicating that alginate oligosaccharides enhance the drought resistance of tomatoes.
alginate oligosaccharides can also act as elicitors to induce plant disease resistance and antibacterial activity. alginate oligosaccharides can stimulate the accumulation of plant antitoxins and alanine ammonia lyases in soybean cotyledons. alginate oligosaccharides can also stimulate the production of phytochemicals in rice cells when treated with water rice sprouts. Plant protectants are beneficial for plants to resist the invasion of diseases and have a positive effect on controlling plant diseases.
