Abstrakt:	Abstract??Systemic acquired resistance (SAR) can be induced in plants by incompatible pathogens, pathogen derived extracts, or certain chemicals as benzothiadiazole (BTH). The aim of this work was to compare changes in peroxidase and chitinase activities, enzymes considered as PR-proteins, caused by BTH and the pathogenPlasmopara halstedii. Hypocotyls from susceptible and resistant BTH-treated sunflower seedlings showed increased peroxidase and chitinase activities. Inoculation withP. halstediiincreased chitinase and peroxidase activities in inoculated hypocotyls from susceptible but not from resistant sunflower seedlings. [ABSTRACT FROM AUTHOR]
