PEROXIDASE, SUPEROXIDE-DISMUTASE AND CATALASE ACTIVITY IN CORN PLANTS DEVELOPED UNDER THE INFLUENCE OF POLYPHENOLIC COMPOUNDS AND DEUTERIUM DEPLETED WATER

Abstract

In this experiment we studied the role of deuterium depleted water and spruce bark (Picea abies L.) polyphenolic extracts in the activity of some enzymatic systems involved in the metabolism of plants of maize (Zea mays L.). Thus, we evaluated the activity of peroxidase, catalase and superoxide dismutase in the leaves and roots of maize, developed in the different experimental variants. It was found that the peroxidase activity decreases in the roots treated with deuterium depleted water and increases when the plants are treated with the polyphenolic extract derived from spruce bark. Also, it was observed an increase in catalase activity in maize plants treated with polyphenolic extract from spruce bark
