Uso de oligosacáridos como estimuladores del crecimiento vegetal en plantas ya germinadas y procedimiento de obtención

摘要

The invention relates to the use of oligosaccharides as stimulators of plant growth in already germinated plants and to a method for obtaining said oligosaccharides. The invention particularly relates to the use of oligosaccharides composed of N-acetyl glucosamine and glucosamine as stimulators of plant growth in already germinated plants, where the percentage of N-acetyl glucosamine in said oligosaccharides is 100% and where the length of said oligosaccharides is between 1 and 6 monosaccharides. The invention particularly relates to the method for obtaining said oligosaccharides, which comprises: (a) resuspending chitin with a percentage of N-acetyl glucosamine of between 85 % and 100 % in water, (b) heating the resulting composition to a temperature of between 120 and 180°C for a duration of between 20 and 40 minutes and leaving to cool to room temperature, and (c) sonicating the resulting composition at a power of between 50 and 60 Hz for a duration of between 5 and 120 minutes at a temperature of between 20 and 25°C.
