LILY SYMPTOMLESS VIRUS IN TULIP |

| Abstract:
Lily symptomless virus (LSV) was transmitted mechanically to only one out of 52 plant species (18 families) tested, i.e. Lilium formosanun (Liliaceae). The aphid species Myzus persicae, Macrosiphum euphorbiae, and Aphis gossypii transmitted LSV in a non-persistent manner from Lilium "Enchantment" to tulips ("Rose Copland"). M.euphorbiae transmitted LSV more efficiently than M.persicae. The yield of LSV-infected tulips ("Peerless Pink") was slightly reduced compared with that of healthy tulips. Two procedures to purify LSV from tulips were applied, one using crude sap and the other sap treated with chloroform. The results of comparative measurements of virus particles in LSV-infected tulip and lily, the mild expression of the symptoms, and the slight reduction of the yield, may suggest that tulip is not a suitable host for LSV. LSV was observed incidentally in stocks of commercial growers. The paper has been offered to the Neth.J.Pl.Path. | |
