Two subspecies were recognised, subsp. thurifera in Europe and subsp. africana in Africa. The aim of the study was the comparison of phenetic diversity to the pattern of AFLP geographic differentiation of the species described in the literature. The examination of phenetic diversity was based on the biometrical analysis of 17 populations using 12 morphological characters of cone and seed. The differences among populations were analysed using Student’s t test, analysis of discrimination, UPGMA agglomeration and hierarchical analysis of variance. The majority of morphological characters differentiated at a statistically significant level between populations and between J. thurifera subsp. thurifera and subsp. africana. Three groups of populations were detected using multivariate statistical analyses. The first, well separated, is subsp. africana, while the following two concern subsp. thurifera. The morphological differentiation of populations appeared similar to that described on the AFLP. The Gibraltar Straight appeared to be the most important barrier. | Descripción: | 12 p., mapas, tablas, gráf. | Versión del editor: | http://dx.doi.org/10.1007/s00606-013-0760-7 | URI: | http://hdl.handle.net/10261/95634 | DOI: | 10.1007/s00606-013-0760-7 | ISSN: | 0378-2697 | E-ISSN: | 1615-6110 |
