| Abstract:
Emerging virus infections at the end of the production chain of bulbous crops are subjected to claims and disagreements between trader (grower, exporter) and client (forcer, importer) about the origin of the virus infection. Some virological observations in lilies and irises can be used to distinguish primary infections from virus infections already present in the bulbs at delivery. Discrimination may be possible on basis of type or location of symptoms, distribution pattern of the virus over plant parts or of virus-infected plants in the field or glasshouse. | |
