Le but de ce travail est de determiner parmi des analyses minerales de feuilles et de liege, un ou plusieurs elements mineraux dont la teneur pourrait etre en relation avec la qualite du liege. La ...composition minerale des feuilles et du liege a donc ete determinee pour un certain nombre d'elements (azote, phosphore, potassium, calcium, magnesium, fer, cuivre, zinc et manganese). La qualite du liege est estimee par des experts de l'industrie du liege a partir des ratios de choix visuels des bouchons obtenus de chaque arbre. L'etude des correlations entre les teneurs en elements mineraux du liege et sa qualite indique que, parmi ces mesures, seule la teneur en potassium du liege est liee a la qualite du materiau. De plus, la qualite du liege semble etre independante de la composition minerale des feuilles, consideree comme un indicateur de la nutrition minerale du chene-liege
