THE IDENTITY OF TWO SAP-TRANSMISSIBLE VIRUSES OF CARNATION IN ONTARIO

Abstract

Both carnation mottle virus and carnation ring spot virus, hitherto unreported in Canada, were detected in commercial carnation varieties in Ontario. These viruses were distinguished by their effects on the differential hosts, Gomphrena glabasa L. and two selected clonal lines of Dianthus barbatus L., and by their host ranges, physical properties, and serological reactions. Evidence is presented to show that each is identical with the virus of the same name occurring in this crop in England and the United States.
