[Viruses of orchids of the natural flora in Ukraine].

Orchids from biogeocenosis of natural landscapes of Ukraine (the Crimea, Carpathians) were analyzed for presence of viral pathogens. It is demonstrated that tobacco rattle virus (TRV), tomato aspermy virus (TAV), cymbidium mosaic virus (CymMV) and arabis mosaic virus (ArMV) are the most spreaded pathogens of orchid plants. There are orchid species distinguished in natural flora of Ukraine with characteristic high frequency of viral infection.
