Abstract:
Lilies are grown in Israel to provide cut flowers and bulbs, the latter for both export and local use. The crop is often severely affected by various virus disease, which cause mosaic and necrosis in the leaves, hunting of the plants and reduced quality of the flowers. The following viruses have been identified in lilies grown in Israel: cucumber mosaic virus (CMV), lily symptomless virus (LSV), lily mottle virus (LMoV) (tulip breaking virus) and a variant of LMoV - L6, which induces local lesions on Chenopodium amaranticolor and strawberry latent ringspot virus (SLRV). The first three are transmitted by aphids in a nonpersistent manner; SLRV is transmitted by nematodes. Lily virus X (LVX) was detected in the laboratory using ELISA but this finding remains to be confirmed by an additional method of identification. Often infections by more than one virus, in the past has led to a complete degradation of lily stocks. The sussess of lily production depends, inter alia, on the availability of a simple and reliable assay method for the various viruses, and on the absence of viruses in the propagation stock. The following steps are recommended to produce high quality material: (I) preparation of nuclear stocks from tissue culture; (ii) increase of virus-free nuclear stocks by rapid propagation (commercial laboratories); (iii) growing of foundation stocks under insect-proof conditions; and (iv) distancing propagation fields from commercial lily fields; the propagation fields should be sprayed with insecticides and oils. At each step the material should be checked for viruses and the grower will choose the type of stock according to his needs. The stocks released to the grower should be of a quality that will enable him to grow them for at least three seasons. It is, therefore, advisable to grow new stocks far away from old infected ones.
