Virus diseases of sweet cherry in China
In recent years, sweet cherry (Prunus avium) commercial orchards have become more widespread in China. In Xi'an (Shaanxi), many sweet cherry trees have shown symptoms of shot hole, enation, small reddish and/or yellowing leaves. During spring 1996, nearly 90 % of the trees showed one or several of these symptoms. Leaf samples were collected and tested (ELISA, virus detection kits). The following viruses were found, either alone or in association: prune dwarf ilarvirus, prunus necrotic ringspot ilarvirus, apple mosaic ilarvirus and apple chlorotic leaf spot trichovirus. According to the authors, this is the first report of these viruses in sweet cherry in China.
