Radial growth is an adaptive trait that is expected to vary among forest tree populations when habitat conditions change. Pinus nigra J.F. Arnold (1785), the European black pine, is a forest tree species widely but patchily distributed throughout southern Europe, from isolated locations in north Africa to the Black Sea and Western Asia. While it has been widely used as plantation species since the mid-19 th century because of its strong growth on rather poor soils, the effect of genetic lineages
