We studied the effects of chitooligosaccharides (ChOS) with a mol wt of 5 kD, the degree of acetylation of 65%, and the concentrations from 0.01 to 100 mg/l on the content of hydrogen peroxide in incubation medium and the activity of anionic peroxidase (pI ∼ 3.5) in the segments of wheat (Triticum aestivum) coleoptiles. H2O2 production and peroxidase activity were found to be dependent on the ChOS concentration. After 3 h of incubation, the highest H2O2 level in medium was observed at 0.01 mg/l… CONTINUE READING
