Zusammenfassung: | 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.
Uso de oligosacáridos como estimuladores del crecimiento vegetal de plantas ya germinadas y procedimiento de obtención. Uso de oligosacáridos compuestos de N- acetilglucosamina y glucosamina como estimuladores del crecimiento vegetal de plantas ya germinadas, donde el porcentaje de N-acetilglucosamina en dichos oligosacáridos es dichos oligosacáridos es del 100% y donde la longitud de dichos oligosacáridos es de entre 1 y 6 monosacáridos. Procedimiento de obtención de dichos oligosacáridos que comprende: (a) resuspender quitina con un porcentaje de N-acetilglucosamina entre un 85% y un 100% en agua, (b) calentar la composición resultante a una temperatura entre 120 y 180º C durante un tiempo entre 20 y 40 minutos y dejar enfriar a temperatura ambiente y (c) sonicar la composición resultante a una potencia entre 50 y 60 Hz durante un tiempo entre 5 y 120 minutos a una temperatura entre 20 y 25º C.
