Alginate oligosaccharide is a new and natural plant elicitor and fertilizer additive with good solubility, it has good biological activity and high safety. It also has antibacterial, antioxidant, and other activities, and can be used as a plant growth regulator substitution and fertilizer additive to promote plant growth and improve fertilizer utilization efficiency.
Dora Agritech is a reliable and leading algae oligosaccharide supplier in China. Dora Alginate Oligosaccharide is the world's first ECOCERT AOS product. By using a specific alginate lyase, technicist can effectively filter and extract alginate oligosaccharides with high efficiency and mild reaction conditions. The prepared alginate oligosaccharides are safe and stable with high purity and activity.
Biodegradation of Alginate Oligosaccharides
Alginate lyase can degrade alginate into biologically active alginate oligosaccharides through β-elimination mechanism. The specific alginate lyase used by Dora Agritech can effectively catalyze the degradation of alginate into oligosaccharides with high purity and activity.
Functions for Crops
1. Increase Crop Growth
Alginate oligosaccharide can effectively induce callus production, significantly enhance the content of hormones (indoleacetic acid, etc.) in cells, and promote the expression of auxin-related genes. It can also stimulate the content of hormones, lipase, amylase, and protease, which are important for seed germination and seedling growth and rooting.
2. Stimulant Plant Resistances Ability
The utlization of alginate oligosaccharide can effectively induce and increase the secretion of plant growth hormones such as abscisic acid in plants. The accumulation of abscisic acid in plants can reach 5-7 times the normal level, which has a significant anti-stress effect.
Through Dora's test of applying AOS, it increases the content of free proline, total soluble sugar and resistin, increases the activities of CAT, SOD, POD and PAL, and improves the drought resistance of tomato seedlings.
3. Promote Crop Nutrient Absorption
The structure of agricultural-grade alginate oligosaccharide contains carboxyl and hydroxyl groups, which can combine with ammonium ions (NH4+) in nitrogen fertilizers to form complexes. This process can inhibit the conversion of ammonium nitrogen (NH4+) to nitrate nitrogen (NO3-), thereby reducing nitrogen loss and increasing nitrogen utilization efficiency. At the same time, alginate oligosaccharides can also provide long-term nutrition to plants by slowing down the release of fertilizers.
The low doses of alginate oligosaccharides can promote the absorption of nitrogen, phosphorus, calcium, magnesium, manganese, boron, zinc and other elements by plant roots.
Alginate oligosaccharides have good compatibility with traditional fertilizers, such as Compound Fertilizers, Urea, DAP, Granular Potash, Foliar fertilizers. It can be used as a fertilizer synergist to significantly improve the efficiency of NPK fertilizers by 20% to 30%.
