AB The olive tree (Olea europaea), a non-tropical woody crop that occupies the largest area inthe world, is severely affected by the fungus Verticillium dahliae worldwide. In this regard, there iscurrently detailed information on the level of resistance to this pathogen in the main olive varieties.However, there is little information on quantitative aspects of its anatomy and on the existence ofanatomical differences between varieties that could be related to the differential resistance responseobserved. In the present work, a quantitative study of the xylem of ‘Picual’, susceptible, and‘Frantoio’, resistant, to V. dahliae is carried out. This study also provides quantitative data on thexylem in different areas of the plant, an aspect on which there is not much information for the olivetree. Among the parameters evaluated, it is probably the greater conductive capacity in the xylemtissue that ‘Frantoio’ presents, mainly due to the greater density of its vessels, which has a morerelevant role in the resistance and natural recovery that this cultivar manifests to the disease. In anycase, these constitutive anatomical differences, and those others that can be induced in plants duringinfections, should be investigated in future work that includes inoculation with the pathogen.
