AI Technical Summary

Technical Problem

In the existing technology, the specific substances in rapeseed pollen that promote plant growth or stress resistance are not clearly identified, the relationship between polysaccharide molecular structure and physiological activity is insufficient, and there is a lack of reliable theoretical and experimental evidence.

Method used

A pollen polysaccharide component 4 was obtained by extracting, separating and purifying rapeseed pollen. A combination of macroporous adsorption resin column, ion exchange chromatography column and gel chromatography column was used to separate polysaccharide component 4 with a specific structure. Infrared spectroscopy and nuclear magnetic resonance analysis were performed to determine its main repeating structural units and monosaccharide composition.

Benefits of technology

The study demonstrated the significant effects of pollen polysaccharide component 4 on plant growth promotion and stress resistance, providing a reliable theoretical basis and experimental foundation, and laying the groundwork for the development and research of pollen polysaccharide resources.
