POLYEL - COMPOUND WITH ANTIOXIDANT PROPERTIES

A new complex compound, Polyel, which contains thiourea, macro- and microelements in the form of salts and coordination complexes, as well as vitamins, was obtained and tested. Biological tests were performed in laboratory experiments and in the vegetation complex of the Institute of Genetics, Physiology and Plant Protection. As subjects of investigations served the plants Glycine max (Merr) cultivars L. ‘Deia’, ‘Moldovița’, and ‘Enigma’ varieties, grown in the Mitcherlih vegetation pots with a volume of 40 kg soil and exposed to the drought stress at the phase "flowering - pods formation”. The beneficial effect of Polyel on antioxidant protection systems by reducing the accumulation of malondialdehyde (MDA) and intensifying the activity of antioxidant protection enzymes has been established. Polyel has been shown to be one of the new biologically active chemicals that can be used in agriculture to reduce the negative impact of oxidative stress caused by reactive oxygen species (ROS). The use of Polyel as a physiologically active substance (PAS) with antioxidant proprieties for pre-treatment of seeds and foliar apparatus is much more effective under moderate drought conditions.
