Dinamica răspunsului antioxidativ la tomatele cu diferit tip de interacțiune cu agentul viral

The defensive response of 4 tomato genotypes to Tobacco Mosaic Virus or Tomato Aspermy Virus was evaluated according to 3 indices - peroxidase and catalase activities and hydrogen peroxide content. The response was differentiated according to the applied viral infection, the genotype and dynamics of the infection process. Particularities have been attested in the reaction of the antioxidative response at different stages of the pathogenesis - increasing or decreasing of the evaluated indices compared to the healthy control.
