Abstract

Two biologically distinct strains of potato potexvirus X (PVX) were recovered by sap inoculation from vines of cvs Carignan and Grenache in two different Tunisian localities. In a Grenache vineyard, PVX was detected by ELISA in about 4 % of the vines. Morphological, physico-chemical, serological and ultrastructural properties of both PVX strains from grapevine were the same as those of ordinary isolates of the type species, as shown by the results of comparative investigations. PVX seemed little pathogenic to grapevines, and was re-inoculated to grape rootlings with difficulty.
