The role of peroxidase in the increasing of soybean plant resistance to unfavorable factors. M.P. MIHAILOVA

The research results of specific activity of peroxidase in soybean leaves of variety MK 100, selected by the All-
Russian Scientific Research Institute of Soybean, under the influence of herbicide Pulsar (active ingredient imazamox) and BioLarix preparation obtained by the processing of Dahurian larch (Larix gmelinii) are presented. The studies were
conducted on the experimental field of the ARSRI of soybean in 2016–2018. It was established that the annual use of the
herbicide Pulsar in the phase of the 3rd ternate leaf led to a decrease in the specific activity of the enzyme being studied. The preparation of natural origin reduce the negative effect of the herbicide, caused activation of the enzyme peroxidase and lead to an increase in metabolic processes that contributes to the adaptation of soybean plants at the cellular level. As a result of the action of the larch extract, the biological yield of soybean seeds increased on the average over 3 years by 0.2 t/ha.
