Abstract Isoenzymes were used to evaluate gene diversity and genetic differentiation among six populations of wild cherry (Prunus avium L.) in France. We contrast the genetic characteristics of a population resulting from a recent colonization with those of a much older population of the same species. No significant genetic structure was observed among populations; in this respect wild cherry does not differ from other forest trees. No founder effects could be detected in the newly colonized population. To explain the results, we discuss classic explanations for the lack of genetic differentiation among populations, including balancing selection and neutral drift/migration. In order to account for the absence of founder effects, we propose a hypothesis based on the life cycle of forest trees, namely that the length of the juvenile phase reduces the impact of small numbers of initial founders.
