Influence of low-intensity electromagnetic radiation of the millimeter range on the antioxidant system of juvenile Glycine max L. plants under osmotic stress

Abstract

This study is devoted to identifying the adaptogenic effect of low-intensity electromagnetic radiation (EMR) of the millimeter (MM) range (wavelength – 7.1 mm, radiation frequency – 42.3 GHz, radiation power flux density – 0.1 mW/cm2) on the antioxidant system indicators of juvenile plants Glycine max L., cv. Apollo under osmotic stress caused by salinity. The stimulating effect of millimeter-wave electromagnetic radiation on the content of proline and carotenoids in Glycine max L. plants was revealed. The results obtained on the quantitative content of carotenoids showed that their content increased both in the normal conditions and under osmotic stress by an average of 1.2–1.8 times. An increased content of free proline in leaves was found in comparison with soybean roots under optimal conditions and under salinity.
