USEFULNESS OF THE GRAPEVINE VIRUS-INFECTED COLLECTION
Journal Title: Current Trends in Natural Sciences - Year 2012, Vol 1, Issue 1
In order to use the virus-infected material as reference in various studies, a grapevine virus collection was established at NRDIBH Ştefănşti-Argeş. The vines are infected with 1-3 of the main specific viruses of this crop: fanleaf virus, leafroll associated virus serotypes 1+3, fleck virus and virus A. Different lots of plants belonging to the same cultivar are infected with different viruses. The own rooted or grafted potted plants are maintained in an insect-proof greenhouse. The main goals of the study of grapevine under the influence of virus infection had in view: symptoms, in vitro behaviour of virus infected grapevine, virus elimination, plant positive control in the diagnostic process. The symptoms produced by viral infection can affect the whole plant (systemic symptoms) or they are visible on certain parts of the plant (local symptoms). In vitro studies of virus infected grapevines comparatively with the healthy material aimed with the quantitative and qualitative aspects of the culture: multiplication and rooting rates, shoots elongation, abnormal cuttings and vitrification phenomena. Infected grapevine cultivars and clones were subjected to virus elimination through thermotherapy, chemotherapy or electrotherapy, combined with in vitro culture. The diagnosis of leafroll, fleck, vein necrosis and corky bark diseases have been done by in vitro micrografting, as rapid biological method of virus detection. Samples collected from infected vines were used as material testing for virus detection by ELISA in inter-laboratory comparisons and Iaboratory-performed validation.
