INFLUENCE OF THE BIOLOGICAL MEDIUM "ZAMIN-M" ON THE ACTIVITY OF OXIDATION-REDUCTION FERMENTS IN POTATO TUBERS DURING THE STORAGE PERIOD.

This article examines the effect of the Rhizobacterium-based biological agent "Zamin-M" on the antioxidant defense system and enzymatic activity of potato tubers during storage. During the study, the dynamics of activity in the main oxidative-reducing enzymes—peroxidase, catalase, and polyphenol oxidase—were analyzed within the tuber cells. Laboratory results indicate that biological treatment regulates oxidative stress in tubers and ensures stable high activity of antioxidant enzymes. This allows for the slowing down of cell membrane degradation and the formation of induced resistance to phytopathogens. The article scientifically substantiates the fundamental importance of the biological agent in regulating potato tuber metabolism.
