Multivariate statistical methods were used to study the relationship between leaf water use efficiency (WUE) and physiological, biochemical and morphological traits of eight Pedunculate oak half-sib lines grown in progeny test. The results evidenced that stomatal conductance and net photosynthesis were the most significant traits associating closely with WUE. In contrast to stomatal condiuctance which had major effect on WUE, net photosynthesis achieved significant influence on WUE partially through the direct effect, and partially indirectly via stomatal conductance. In addition, the results evidenced that leaf anatomical traits, such as stomatal density and stomata guard cell length were highly correlated with stomatal conductance and WUE suggesting that these characteristics could be good indicators in the selection for water-use efficient half-sib lines. The paper provides a detailed insight into the complex linkage between WUE and functional leaf traits in Pedunculate oak half-sib lines.
