| Abstract:
Pox is a serious stone fruit desease caused by the plum pox virus, a potyvirus of which various different isolates exist. In nature it propagates through the vegetative multiplication of infected plants and through aphid carriers. The incubation period is influenced by many factors. Some of these are as follows: the species, the cultivar, the time and the method of infection, the carriers and the strains of the virus involved. PPV is the cause of serious damage to peach, plum, and apricot orchards. The aim of this trial was to observe the propagation and the degree of infection of the pox virus in the different species of stone fruit plants existing in the Istituto Sperimentale per la Frutticoltura, Rome collection. A total of 1239 peach, plum, apricot and nectarine plants were tested by subjecting them to the direct ELISA Test (Enzyme-linked immunosorbent assay) with the use of Sanofi antiserum. The samples of leaves were soaked in a 1/5 (w/v) solution in the presence of a PBS Tween-PVP buffer. A total of 166 different genotypes were found to be infected with the plum and peach varieties being the most infected. Of the seedlings, being the plum rootstocks and apricot were the most infected. The highest ratio of infection in all the trial plants was found in the dwarf peach genotype (Calipso). | |
