Effect of artificial light on the symptoms produced by two yellow mosaic viruses

Summary

During the winter months, greenhouse-grown cucumber plants infected with cucumber virus 4 may show abnormal symptoms indistinguishable from those caused by the closely related cucumber virus 3. Similarly, Turkish tobacco plants infected with yellow aucuba mosaic virus may be difficult to differentiate from plants infected with green aucuba mosaic virus. In both cases, it has been possible to verify the identity of the yellow-type virus in plants showing atypical symptoms by irradiation of the plants with 500-watt or 1000-watt light bulbs in suitable reflectors. Such illumination was found to cause the appearance of typical symptoms in cucumber virus 4 infected plants and in yellow aucuba mosaic diseased plants in 2–5 days.
