Set of virus-free cuttings of indicator plants were put to rooting for the purpose of GLRaV-3 biological detection and characterization. Indexing plants includes following grapevine cultivars: Pinot noir, Merlot and Cabernet franc. Cuttings of autochthonous cultivar Tribidrag were also put to rooting so the symptoms occurrence as well as the morphological, physiological, biochemical changes after the virus infection could be observed and described. Special attention will be paid on the interaction between virus and host plants by exploring the dynamic of virus replication throughout the infection processes.
Some rooted seedlings were already transplanted into pots and placed in a greenhouse chamber, under the proper irrigation, nutrition and protection regime.
