Abstract

Mit Hilfe des serologischen Latex-Testes wurden 121 Reben aus 14 Weinbergen an der Mosel, Nahe und Rhein auf das Vorhandensein von Tabakmosaik-Virus untersucht. Das Virus wurde in 36 Reben der Sorten Riesling, Silvaner und S 88 festgestellt. Der Nachweis des Virus durch Abreibung von Rebenblatt-Preßsäften auf ein Testpflanzen-Sortiment verlief negativ. Abreibungen brachten erst positive Ergebnisse, als dazu beim Latex-Test erhaltene Niederschläge und aus Blattpreßsäften gewonnene Viruspräparate verwendet wurden. 121 grape vine plants from 14 vinegards on Mosel, Nahe and Rhein were tested serologically by means of the latex test for the presence of tobacco mosaic virus. The virus was found in 36 plants of the varieties Riesling, Silvaner, and S 88. Sap-rubbing inoculations of grape vine leaves to several tests plants caused no infections. Inoculations were successful, however, when flocculations obtained in the latex test or partially purified preparations from leaf sap were used.
