Some physiological and biochemical characters of soybean varieties in intensive cultivation technology

Object of research – soybean varieties Zusha, Lancetnaja, Mezenka, Svapa. The aim of this study was to establish the effect of remedies and fertilizers on biochemical parameters, yield and grain quality. Lancetnaja varieties of plants in a bud phase peroxidase activity has increased to 62% and lipid peroxidation level decreased by 20%. In the phase of filling seeds increased growth performance, malonic dialdehyde decreased by 24%, with high peroxidase activity, i.e., the intensity has increased physiological and biochemical processes and ensure receipt grain yields 2.10 t/ha. Mezenka varieties have a phase of budding growth indicators, strengthening occurred, however, led to increased lipid peroxidation, probably related to the high activity of enzymes utilizing hydrogen peroxide. Noted the decline in activity at 37% of malonic dialdehyde and increase of peroxidase activity at 13%, compared with controls. Grain yields in this class was 1.50 t/ha. Varieties have Svapa during the phase budding found 22% decrease in intensity of utilization and lower peroxide malonic dialdehyde. The analysis found reduced activity of the enzyme in the experience at 34% below control level on 46% of malonic dialdehyde. Grain yields in this class was 1.83 t/ha. With a slight decrease in the free-radical processes, in particular the peroxidation of membrane lipids in varieties of Zusha, peroxidase activity increased compared to control at 27%. In the days that followed the trend in the increase of peroxidase activity and reduction of malonic dialdehyde continued. Yield grade was 1.60 t/ha. The ambiguous reply redox processes in soybean cultivars can be associated with individual sensitive varieties to treatments for extremely arid weather conditions spring-early summer, and various physiologic-biochemical status before treatments.
