Sanitary status of plum, peach and apricot in Albania and characterization of some Albanian plum pox virus isolates
1994
Myrta, A.
Surveys were carried out in plum, peach and apricot orchards and varietal collections of stone fruit trees in Albania, for assessing the presence and distribution of virus and virus-like diseases. Biological assays consisting in mechanical inoculation to herbaceous hosts from glasshouse-forced cutting or field samples and graft transmission to GF 305 were made in winter and spring 1994. The following viruses are present: Plum Pox Potyvirus (PPV), Prunus Necrotic ringspot (PNRSV), Apple Mosaic (ApMV), Prune Dwarf (PDV) Ilarviruses, Apple chlorotic leaf spot trichovirus (ACLSV), Tomato ringspot (ToRSV), Tomato black ring (TBRV), Arabis mosaic (ArMV), Raspberry ringspot (RRV), Cherry leaf roll (CLRV) and Strawberry latent ringspot (SLRV) nepoviruses. The prevailing viruses were PPV, ACLSV, PDV and PNRSV. PPV infections were rare in apricot and peach. No infection by ApMV or any of the nepoviruses was detected. To date, none of the graft-inoculated GF 305 seedlings has shown any symptomatological reaction. The preliminary characterization of Albanian PPV isolates from plum and apricot showed that they have a similar biological behaviour but a wider host range than M and D strains. Based on the symptomatology and timing of expression in Chenopodium foetidum, the Albanian PPV isolates were tentatively identified as belonging to the so-called intermediate biological strain, although the behaviour in Nicotiana clevelandii sap showed the Albanian PPV isolates to be closer to Yellow biological strain.
