Effects of chitosan oligosaccharides on cold resistance of plants
Early spring and late frost and the arrival of winter result in serious crop freezing injury, which affects the yield and restricts the development of crop industry. Therefore, the study of cold resistance has important guiding significance for the high and stable yield of crops.
Chitosan oligosaccharides are a series of oligosaccharides with a certain degree of polymerization and a certain structure after the degradation of chitosan. Studies have shown that oligosaccharides can regulate and stimulate plant growth, development and disease resistance, and chitosaccharides have excellent and stable effects in preventing and reducing the effects of freezing injury on plants.
Shell oligosaccharides by spraying and seed treatments to improve leaf SOD, POD and CAT activity of protective enzyme and decrease membrane lipid peroxidation products MDA accumulation to maintain a relatively low level of free radicals in cells, reduce the low temperature damage to cell membrane, thus reducing the electrolyte leakage, reduce the cell damage, in order to maintain cell regeneration and adjustment ability, alleviate plant tissue chlorophyll content under low temperature is reduced, maintain photosynthesis at a certain level. Chitosan oligosaccharides can also improve the root activity of cold-damaged plants, so that plants can still absorb a certain amount of nutrients at low temperature, maintain the normal metabolism, and finally effectively improve the cold-resistance ability of plants.
Chitosan oligosaccharide is a new kind of anti-cooling agent with good water-solubility, non-toxicity, no pollution, low viscosity, low dosage, obvious effect, low cost and easy to use.
