Seven morphometrical characters were measured in 90 plants from each provenance. Analysis of variance showed highly signiﬁcant diﬀerences for all characters. The phenotypic coeﬃcient of diﬀerentiation reached 0.24 for the form and 0.22 for height, thus revealing a strong structuring between the provenances. Comparative study of growth among the provenances revealed more vigorous growth and better survival rate for those from Morocco, Spain, and Portugal, which may constitute better materials for aﬀorestation. Furthermore, this variability appeared to be geographically structured and would be mainly genetically controlled, as cork oak provenances were cultivated under the same environmental conditions. Our results should be helpful for guide forest managers in aﬀorestation.</style></abstract></record></records></xml>
