Antioxidant activity of winter wheat when treated with the biopreparation Nigor++

The influence of stress factors on the plant can lead to deterioration of plant functioning and loss of yield. The use of biological preparations based on plant cell elicitors in the technology of grain cultivation makes it possible to regulate the antioxidant activity of plants under abiotic stress. Treatment with the biopreparation Nigor++ in the tillering phase leads to noticeable changes in the balance of antioxidant substances in winter wheat plants Moskovskaya 39. Repeated treatment of Nigor++ after 16 days in the earing phase reduces AOA by 21.8, and by the flowering phase leads to a drop in this indicator by 51% relative to the tillering phase and by 59% relative to control plants. The use of Nigor++ increases the immune status of plants, reduces the concentration of antioxidant substances or reduces their activity due to the formation of stable complexes with magnesium ions included in BP, as well as binding them to highly active free radicals that occur during autoxidation, converting them to low-activity.
