Symptomatic and asymptomatic leaves of peach (sel. IF7230685) and apricot (cv. Tyrinthos) infected by “plum pox virus” (PPV) were analysed for net photosynthesis, peroxidase activity and chlorophyl content. The presence of the PPV in the leaves excised was verified with the ELISA test. The PPV affected the photosynthetic system more strongly in peach than in apricot. Peroxidase activity (PA) and chlorophyl content were also affected. PA was a good indicator of infection, and also made it possible to distinguish different degrees of infection.
