Abstract
- The correlation between intensity of lipid peroxidation and changes in antioxidant capacity of sugar beet plants (cv. 'Drena') infected with Rhizoctonia solani Kühn isolate (AG 2-2 IIIB group) was studied. Successful inoculation was confirmed by the presence of infection cushions in a cross section of leaf petioles. On the 7 day of the experiment, phenylalanine ammonia-lyase (PAL; EC. 4.3.1.5) activity was in negative correlation with intensified lipid peroxidation process in leaves of sugar beet plants (r= -0 .99). Also, in leaves and roots of inoculated sugar beet plants, total flavonoids content (35% and 20%, respectively) and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity (80% and 55%, respectively) were significantly reduced. Necrotic processes resulting from R. solani infection of sugar beet plants was followed by induction of plant phenolics metabolism; however, antioxidant capacity of these plants was reduced.
