| Apparently, plum pox actually can be transmitted through seeds: http://www.actahort.org/books/130/130_51.htm But these apricot seedlings didn't actually get the disease, even though they came from infected trees: http://www.ncbi.nlm.nih.gov/pubmed/10073234 In other species, for other viruses, seeds are generally a safe way too get virus-free plants. I know, for instance, that lilies are often grown from seed to avoid viruses that infect vegetatively-propagated plants. Of course, that might not be relevant to this virus. This page: http://plantclinic.cornell.edu/FactSheets/plumpoxvirus/plumpox.htm says: " PPV was introduced into several European countries via infected nursery stock or infected buds grafted onto healthy trees. This is the only known method of long-distance transmission." This one little apricot seedling of mine looks perfectly healthy. I guess everyone has to make up their own minds about whether or not they want to risk planting these. Let me know if you'd still like seeds.
