The ecological passport (ECOPASS) reported here was constructed from a combination of biochemical, anato-morphological and ecophysiological gas exchange parameters measured on several fast growing poplar clones. Through multivariate statistical techniques the ECOPASS model was shown to be able to reflect not only the genetic origin and the relative impact of the different parameters of the clones but also their production potential. The correlation found between three principal components (related to ecophysiological, biochemical, and morphological parameters) and productivity of the five clones was 96 percent, while the ecophysiological parameters alone were still 85 percent correlated with field productivity.
