FIELD: chemistry.

SUBSTANCE: plant growth intensification is realised by processing of plant seeds or a plant, which germinates from the seeds, with an effective quantity of at least one chitooligosaccharide (CO), presented by formula: in which R₁ stands for hydrogen or methyl; R₂ stands for hydrogen or methyl; R₃ stands for hydrogen, acetyl or carbamoyl; R₄ stands for hydrogen, acetyl or carbamoyl; R₅ stands for hydrogen, acetyl or carbomoyl; R₆ stands for hydrogen, arabinosyl, fucosyl, sulphate, 3-0-S-2-0-MeFuc, 2-0-MeFuc or 4-0-AcFuc; R₇ stands for hydrogen, mannosyl or glycerin; R₈ stands for hydrogen, methyl or -CH₂OH; R₉ stands for hydrogen, arabinosyl or fucosyl; R₁₀ stands for hydrogen, acetyl or fucosyl; and n is equal 0, 1, 2 or 3.

EFFECT: invention makes it possible to increase the plants yield.
