The correlation between leaf symptoms and concentration of plum pox virus in peach cultivars


, : The correlation between leaf symptoms and concentration of plum pox virus in peach cultivars. Ochrana Rostlin 32(1): 1-8

Individual trees of peach cultivars in an orchard naturally infected with plum pox virus (PPV) were evaluated for the presence of the virus by ELISA and by visual symptoms. PPV was serologically detected in most trees of the cultivars. The relative concentration of PPV determined by ELISA was used to test for its correlation with PPV symptoms on peach cultivars. Differences in relative concentration of PPV were found among infected cultivars. The level of relative concentration of PPV in flowers determined by ELISA was positively correlated with the intensity of leaf symptoms. Preliminary evaluation showed a low relative concentration of PPV in flowers and mild symptoms on leaves of the cultivars Harmony, Envoy, Favorita Morettini 3 and NJC 102.
