| Abstract:
In a study of woody ornamental and indigenous plants in Britain apple chlorotic leafspot virus (CLSV) was detected in 9 genera of Rosaceae, spy epinasty and decline and stem pitting viruses in 3 genera, prunus necrotic ringspot (PNRSV) and sooty ringspot viruses in 2 genera and prune dwarf (PDV) and pear vein yellows viruses in single genera. Apple mosaic virus (ApMV) was detected in four plant genera including the Hippocastanaceae and Corylaceae. In a nationwide survey CLSV was detected in 25% of hedgerow hawthorns (Crataequs spp.) and in 5% of hedgerow blackthorn (Prunus spinosa L.). PNRSV and PDV were also detected in 4–5% of hedgerow blackthorn. No aphid or seed transmission of CLSV was detected in hawthorn. PDV was detected in 25% of P. avium seedlings and PNRSV, but not ApMV, was detected in roses, their pollen and in 1% of rose seedlings. No seed or pollen transmission of ApMV was detected in Aesculus species. Pome fruit viruses significantly reduced the vigour of some Sorbus species and PNRSV and PDV reduced the bud takes of respectively Rosa and P. serrulata cultivars. | |
