In Central-European forest stands on southerly to south-westerly exposed slopes of hills with shallow soil, European beech (Fagus sylvatica L.) loses its predominance over other deciduous tree species such as oak (Quercus spp.) or whitebeam (Sorbus aria [L.] Cr.) due to limited availability of water. To test whether winter frost is an additional factor affecting the performance of beech at such exposed sites, we measured the minimum air temperatures between the sampling dates, and determined ...In Central-European forest stands on southerly to south-westerly exposed slopes of hills with shallow soil, European beech (Fagus sylvatica L.) loses its predominance over other deciduous tree species such as oak (Quercus spp.) or whitebeam (Sorbus aria [L.] Cr.) due to limited availability of water. To test whether winter frost is an additional factor affecting the performance of beech at such exposed sites, we measured the minimum air temperatures between the sampling dates, and determined the frost sensitivity of F. sylvatica and of co-occurring tree species (Quercus petraea [Matt.] Liebl., Quercus pubescens Willd., Quercus robur L., S. aria [L.] Cr.) eight times during the winter months, from October to March, at two sites in the low mountain ranges of Central Germany, which share the same climatic, topographic and edaphic conditions. At each site, two localities (stand margins and the interior of the stands) were compared. The frost sensitivity was determined in twigs of the trees using the electrolyte leakage method.» weiterlesen» einklappen
