Beech occurs on very acid to alkaline soils. Seedlings from the fruit of six provenances originating on acid to alkaline soils in France were grown on an acid and an alkaline substrate for 3 years. Differences in total heights showed provenance and substrate effects as well as a strong provenance-substrate interaction. Trees on the alkaline substrate performed better than those on the acid substrate. Two provenances originating on alkaline soils grew better on the alkaline substrate and one acid soil provenance grew better on the acid substrate. The other 3 provenances performed similarly on alkaline and acid substrate. Other characteristics such as leaf weight and Ca and Mg leaf content were closely correlated to total height. Observations made at ages 1 and 3 showed that beech seems to adapt itself to alkaline conditions. Conclusions are drawn for the use of beech in reforestation. Forest Sci. 29:403-411.
