Abstract

Prominent virus-like ringspot symptoms were observed on the leaves of Dracaena surculosa Lindl. Attempts to transmit a casual virus by mechanical inoculation on some conventional test plants remained unsuccessful. However, leaf squash preparation revealed filamentous virus particles, as well as structures which could be parts of »pin- wheel« inclusions. dsRNA, corresponding approximately to the replicative form of RNA of potyviruses, was isolated from symptoms bearing leaves. The results obtained suggest that the ringspot symptoms on D. surculosa could be provoked by a potyvirus infection.
