(CarMV) and carnation ringspot virus (CarRSV) using test plants and serological tests for identification of CarMV and test plants reactions for identification of CarRSV

Carnation vein mottle virus (CarVMV) was isolated from glasshouse-grown Dianthus caryophyllus L. originating from Split. The same virus was obtained also from D. caryophyl­ lus, D. carthusianorum L. and D. barbatus L. which were grown in the open in Zagreb and the surroundings. The virus was identified on the basis of host plants, non-persi­ stent mode of transmission by M yzus persicae Sulz. and by analysis of ultrastructural changes in host cells. Light mi­ croscopic inclusions of CarVMV in the epidermal cells of Chenopodium quinoa Willd. and C. am aranticolor Coste et Reyn, leaves are described. Three forms of these inclusi­ ons are illustrated: granular bodies, bodies showing strong light diffraction and containing vacuoles, and aggregates of cylindrical cytoplasmic inclusions in the form of clusters of needles. Cucumber mosaic virus was isolated from D. caryophyllus which was grown in the open in Zagreb. This is the first finding of the two viruses on carnations in Yugoslavia.
