摘要

An account is given of the results of extended investigations carried out in the main stone fruit growing areas of Apulia, Italy, to assess the sanitary condition of crops and to identify the prevailing virus and virus-like diseases. The studies involved field surveys for the observation of symptoms; mechanical transmission on herbaceous hosts for the isolation of viruses; graft-transmissions onto woody indicators for detection of virus-like diseases, and ELISA and IEM for virus identification. Symptoms were observed in all species, including chlorotic, yellowish spots and/or line patterns, reduced growth and deformation of leaves, deformation and irregular maturation of fruits, pitting of stems. Almond and cherry had very high infection rates (80% and 65%, respectively). On other fruit trees, the infection levels ranged between 25% (plum) and 35-36% (peach and apricot). Prunus necrotic ringspot ilarvirus (PNRSV), prune dwarf ilarvirus (PDV), apple mosaic ilarvirus (ApMV) and apple chlorotic leafspot trichovirus (ACLSV) were common in all the species tested, with ApMV prevailing in almond (45%), PDV in cherry (75%), PNRSV in peach and plum (55% and 33%, respectively) and ACLSV in apricot (33%). PPV was detected in some young apricot and plum plantings. Through sanitary selection and sanitation by heat therapy, 160 different virus-tested cultivars and/or clones (41 peach, 22 cherry, 17 apricot, 23 plum and 57 almond) and 10 different rootstocks were obtained which have now entered the regionalcertification programme.
