| Popis: | The article deals with the possibility of using pectin and chitosan, and their water-soluble derivatives as film-forming compositions for pre-treatment of seed crops. The authors of the present research investigate the different methods of destructing the watersoluble polysaccharides of natural origin – citrus pectin and succinate of chitosan – (by means of acid gydrolysis and radical-chain destruction) for receiving low-molecular homologues. It is revealed that the dynamic viscosity of the solutions of pectin and succinate of chitosan in case of acid hydrolysis, and in case of radical-chain degradation, is reduced drastically in the first 60-70 minutes of the process. It is shown that 0,001 % solutions of pectin and succinate of chitosan degradation products have a positive impact on the energy growth of Ekada-70 and Bashkirskaya wheat seed varieties. The optimum concentration of degradation products of citrus pectin and chitosan succinate as part of film-forming composition for seed pre-treatment is 0,001 %. |
