摘要：

Our recent results on the plum pox virus (PPV) epidemiology show that PPV spreads very rapidly in plum tree plantations in the contaminated areas. A clearing of the PPV-infected trees reduces significantly the spread of the virus but does not eliminate the disease. Some plum tree cultivars, hybrids and rootstocks (Scoldus, Alina, Cristi, BN 1/8F1, BN 2Gr. etc) showing field resistance could not be infected with PPV by natural way. However, they could be infected with PPV by artificial inoculation except for the plum tree cv. Local of Dragasani and the BN 4Kr myrobalan, which proved to be immune to PPV. PPV was not transmitted through seeds in plum tree and myrobalan in the nursery. The Hyalopterus pruni aphids were found PPV-positive by an enzyme-linked immunosorbent assay (ELISA).
