Population differentiation has been investigated in forest trees since provenance tests were established. A vast amount of results has accumulated in numerous reports and articles about intraspecific variation, that have been summarized in textbooks about forest genetics (Wright 1976). Provenance differences exist for almost any adaptive trait that has been measured in provenance test and for almost any species. These results contrast markedly with data based on biochemical markers as isozymes. As shown by the literature review by Hamrick et al. (1992), forest trees usually exhibit extremely low levels of differentiation for isozymes. Results derived from isozyme surveys are confirmed by other molecular markers, with the exception of organelle markers which follow usually uniparental inheritance. The discrepancy of differentiation between adaptive traits and molecular markers is attributed to the fact that different evolutionary forces affect these traits and that they are controlled by different sets of loci likely to be unlinked.
