About 50 years ago (in the 1960’s), 30 Tunisian Aleppo pine provenances were planted in Korbus arboretum (NE of Tunisia). For this study, only twelve provenances were selected and assessed. The selected provenances were evaluated for seed production, tree height and diameter. Results showed high inter-provenance variability for all the traits considered. However, within this site, the produced overall Aleppo pine cones per tree was less than the half in comparison to the interior forest of the country. Similarly, the average produced cone was lighter with less seeds content compared to non maritime coastal forests. The developed mature cones per tree in terms of number and weight were the major factors influencing seed yield within the site.References
