摘要

The presented experiments describe changes in starch and reducing sugar content in germinated soy bean and alfalfa seeds or wheat grain as the result of abiotic stress induced by Fe2+ ions. The examined plants were germinated in hydroponic cultures at 0-25 mM concentrations of FeSO4. The stressing factor influenced on content of the examined saccharides and even increased, in some examined conditions, the starch and oligosaccharides hydrolysis. The greatest effect on technological properties of flour may have had an addition of powder, which was prepared from germinated wheat. Changes observed in reducing sugar and starch content for legumes sprouts should not influence the properties of raw material for cereal processing.
