Studies on Lily Virus Diseases : the neerotic-fleck Complex in Lilium longiflorum

Studies on Lily Virus Diseases : the neerotic-fleck Complex in Lilium longiflorum

Phytopathology, Lancaster, Pa., 34: 6, 529-555

Details are given of experiments in the United States from which it appears that the necrotic-fleck disease of Easter lily (Lilium longiflorum) is due to concurrent infection with cucumber-mosaic virus and a lily symptomless virus (LSV) for which the name, Adelonosus lillii, gen. et sp. n., is proposed; that mottle viruses (LMV) consistently associated with necrotic fleck in commercial Easter lilies are not an essential part of the complex; and that Aphis gossypii, Glov., is a specific vector for LSV and therefore for the complex CV (cucumber-mosaic virus)+LSV. When transferred from flecked lilies to virus-free seedlings, A. gossypii transmitted necrotic fleck, Macrosiphum solanifolii, Ashm., and Myzus persicae, Sulz., transmitted CV and LMV but not fleck, and Aphis fabae, Scop., Macrosiphum lilii, Monell, Myzus circumflexus, Buckt., and Macrosiphum solani, Kalt. (Myzus convolvuli, Kalt.) did not transmit any virus. Necrotic fleck was produced by Aphid (but not sap) transmission of LSV to lilies infected with CV, and by Aphid or sap transmission of CV to symptomless lilies infected with LSV. LSV was compared with lily-rosette virus in some experiments. Both were of the persistent group, having latent periods of 4-6 and 3-7 days, respectively, in A. gossypii, but LSV did not protect Easter lilies from infection with lily-rosette virus. The latent period permits the separation of LSV from LMV. Tests of host range indicated that LSV is confined to Easter lily, though the susceptibility of tulip, Colchicum and Gloriosa remained in doubt. No evidence of susceptibility to this virus was found in the other plants tested, which comprised 56 species representing 40 genera, including Lilium, and 9 families, chiefly Monocotyledons. A. gossypii transmitted CV from necrotic-flecked Easter lilies to Calochortus sp., Colchicum autumnale, Gloriosa roths-childiana and Fritillaria pudica, not previously recorded as susceptible to this virus.
