Abstract

Hydrogen peroxide impact upon the activity of superoxide dismutase (SOD), catalase (CAT), development of lipid peroxidation processes (LP), photosynthetic pigment content and productivity in conditions of field experiment were studied for winter wheat varieties of different ecotypes, namely Stolychna, Polisska 90 – forest-steppe, and Scala-steppe. It was found that hydrogen peroxide action for 24 h induced LP activity, whereas antioxidative enzyme activity dropped at two varieties. Exception was the Stolychna plants that showed decrease in all indexes studied after treatment. In the next phase of ontogenesis (flowering), however, SOD activity increased both in the plants of Polisska 90 and Scala, while CAT and LP activities were close to control in all plants. The data suggest that treatment by hydrogen peroxide stimulated the formation of general unspecific resistance of plants and increased the grain productivity of winter wheat varieties studied.
