| Abstract:
A survey was carried out to evaluate the sanitary status of pome fruit crops in Albania. Twenty five orchards and/or varietal collections were visited in Central (Kavajë and Elbasan), South-Eastern (Librazhd, Pogradec, Devoll and Korçë) and North-Eastern Albania (Dibër). A total of 140 apples and 19 pears were sampled. Indexing was with the following indicators: (i) in a climatized greenhouse, Malus pumila (‘Virginia Crab’ and ‘Radiant’) and Pyronia veitchii; and (ii) in the open field, Malus pumila ‘V. Crab’, ‘R 12740 7A’, ‘Spy 227’, ‘Lord Lambourne’, ‘Golden Delicious’, Pyronia veitchii, Pyrus communis ‘Nouveau Poiteau’ and ‘LA62’. All samples were tested also by ELISA for the presence of Apple chlorotic leaf spot virus (ACLSV), Apple stem grooving virus (ASGV) and Apple mosaic virus (ApMV). The infection rate was 100% in apple and 84.2% in pear. The prevailing viruses of apple were Apple stem pitting virus (ASPV) (98.6%), ACLSV (97.8%) and ASGV (91.4%). The same viruses were present, but less frequently in pear: PVYV (87.5%), ACLSV (81.2%) and ASGV (12.5%). Only one apple tree was found infected by ApMV and a few samples showed rubbery wood and flat limb. This preliminary survey demonstrates the high infections rate of pome fruits in Albania which is worsened by the recent report of Apple proliferation and Pear decline phytoplasmas in the country. | |
