The multiplication and rooting rates achieved from in vitro cultured explants of Paradox cl. ‘Vlach’, proved to be highly affected by their position in the original shoot. Explants taken until the 3 rd internode below the apical meristem, when systematically subcultured each 30 th days, lost their multiplication capacity on each subculture, their regeneration efficiency becoming almost null after 5 subcultures....
Previous extensive field surveys in olive orchards have revealed high levels of Olive mild mosaic virus (OMMV) and Olive latent virus 1 (OLV-1), frequently appearing in mixed infections. These viruses belong to genus Alphanecrovirus and their RNA dependent RNA polymerase (RdRp),as well as their p6 and p8 amino acid sequences share over 87% identity.
