Regulate plant growth
Alginate Oligosaccharide can be used as a signal molecule to participate in the regulation of plant growth and development. The presence of Alginate Oligosaccharide activates the expression of hormones in plant seedlings, changes the activities of amylase, lipase and protease, accelerates the hydrolysis of endosperm starch, and promotes seed germination and root and shoot growth. Studies have shown that 0.125% Alginate Oligosaccharide is beneficial to improve the germination rate of sorghum seeds and promote the growth of seedlings, while 0.0625% Alginate Oligosaccharide treatment is more conducive to promoting chlorophyll synthesis in sorghum leaves and improving root vigor. The growth-promoting effect of Alginate Oligosaccharide on plants is not only manifested in the increase of plant height, leaf area, root length and other growth indicators, but also in functional leaf chlorophyll content, photosynthetic rate, stomatal conductance, transpiration rate, intercellular CO2 concentration and other indicators significantly increased.
Improve plant stress tolerance
Alginate Oligosaccharide can alleviate the damage to plants caused by adversity (such as pesticides, drought, cold, heat, etc.) by inducing plants to produce resistant substances, and play a role in regulating crop growth. Alginate Oligosaccharide can increase the content of soluble sugar and free proline in plants, enhance the activity of plant antioxidant enzymes, induce the synthesis of phytochemicals, reduce the permeability of cell membranes and the content of malondialdehyde, thereby improving plant stress resistance.
Alleviate the toxic effects of heavy metals on plants
Alginate Oligosaccharide can improve the resistance of plants to heavy metals and protect plants from heavy metals. The study found that low concentrations (0.0625%~1.0000%) of Alginate Oligosaccharide can alleviate the damage caused by Cd to the root tip cells of faba bean, and 0.1250% Alginate Oligosaccharide can increase the mitotic index of faba bean root tip cells, inhibit the production of micronuclei, and reduce chromosomal aberrations; It was also found that the rhizome length and dry weight of wheat seedlings under Cd stress decreased by 20% compared with the control group, while adding 1g/LAlginate Oligosaccharide could improve the resistance of wheat to Cd stress (100μmol/L).
Promote plant nutrient absorption
The structure of Alginate Oligosaccharide contains carboxyl and hydroxyl groups, which can combine with ammonium ions (NH4+) in nitrogen fertilizers to form complexes, thereby inhibiting the conversion of ammonium nitrogen (NH4+) to nitrate nitrogen (NO3-), reducing nitrogen loss and long-term damage to plants. Provide nutrients. At the same time, low dose of Alginate Oligosaccharide can also promote the absorption of N, P, Ca, Mg, Mn, B, Zn and other elements by plant roots.
