Abstract

In the course of studying the responses of four Lycium species (L. australe, L. cestroides, L. mediterraneum, L. pallidum) to 24 viruses we established 56 new host-virus relations (25 local, 15 local and systemic, 16 resistant). From the point of view of virus ecology particularly remarkable is the systemic susceptibility showed by the four species examined to cucumber mosaic virus, by Lycium cestroides to belladonna mottle virus, and by L. mediterraneum and L. pallidum to belladonna mottle virus, lettuce mosaic virus and tobacco mosaic virus. On the basis of the earlier and present research results it can be stated that L. australe is susceptible to 11, and L. mediterraneum and L. pallidum each to 15 vi ruses. Lycium cestroides, a species so far unknown in plant virology proved susceptible to six plant viruses (belladonna mottle, carnation ringspot, cucumber mosaic, Melandrium yellow fleck, tobacco rattle and tomato mosaic viruses). On the basis of their systemic susceptibility to cucumber mosaic virus and resistance to celery mosaic virus Lycium mediterraneum and L. pallidum seem to be suitable for separating the cucumber mosaic virus and eliminating the celery mosaic virus in the case of mixed infections.
