Chitooligosaccharides have the functions of regulating plant growth, development, reproduction and activating plant defense responses.
The purpose of this experiment was to study the effects of different concentrations of oligochitosan on the germination and seed vigor of flax seeds. Chito-oligosaccharides are selected for 0, 0.25g/kg, 0.5g/kg, 1g/kg, 2g/kg, 3g/kg, 4g/kg, 5g/kg, 6g/kg, 7g/kg, 8g/kg concentration of seed dressing The seed germination test was carried out, and each treatment concentration was repeated 3 times. According to the test record data, calculate the germination rate, germination index, germination vigor and vitality index. Experiments show that after different concentrations of oligochitosan seeds are treated with flax seeds, the germination rate, germination vigor, germination index, radicle length and vigor index, seedling length and vigor index of flax seeds are all obtained within a certain concentration range. Improvement. The effect is most obvious when the concentration of flax seed dressing is 0.5-2g/kg.
