Castanea sativa Ancient Trees Across Europe: Genetic Diversity And Conservation Strategy

Long-living trees are witnesses of environmental changes and human interventions; these extraordinary organisms not only represent a historical, landscape and environmental heritage of inestimable value, but they also are a reserve of genetic variability which can considered as a great resource for management programs of forest species. This is the first genetic study on Italian ancient chestnut trees (Castanea sativa Mill.). Ninety-nine ancient trees including the oldest known chestnut in Europe, named ‘Cento Cavalli’, which is believed to be to be between 3,000 and 4,000 years old, were collected. For each tree, more than one sample from canopy and root suckers was collected to test for t…
