Notes:
Apple mosaic ilarvirus (ApMV) was detected in all (160) hazel (Corylus avellana) cv. Negret orchards assayed in Catalonia, north-east Spain, during 1997 and 1998. In a preliminary survey, using enzyme-linked immunosorbent assay (ELISA), only 9 of the 320 samples collected appeared free from ApMV and three of these individuals indexed ELISA positives when re-tested. The spread of ApMV was studied in a plantation of Negret hazel in which virus-free trees were randomly interspersed with graft-inoculated individuals. When tested by ELISA 10 years after planting, 15% of the ungrafted trees contained ApMV. At that time, 8% of seeds on ungrafted and virus-free trees and 54% of seeds on ApMV-inoculated trees indexed ApMV-positive. These results are discussed in terms of pollen-mediated inoculation.
