A Study of the Antiviral Activity of Cyclopentene β,β'-Triketone Disodium Salt in the Leaves of Two Nicotiana tabacum L.Cultivars Infected with Tobacco Mosaic Virus

摘要

The effect of disodium salt of 2-acetyl-4-hydroxycarbonylmethylthio-5-chlorocyclopent-4-en-1,3-dione on development of the infection caused by tobacco mosaic virus in the leaves of two Nicotiana tabacum L. cultivars-an hypersensitive cultivar Xanthi-nc and systemically affected Samsun-was studied. The results suggest that this compound interferes with reproduction of the virus. This antiviral effect displayed the highest activity when applied in a mixture with the virus, presumably due to its action on both the plant and the virus.
