Site conditions and species identity have a combined effect on fine root growth of trees in pure and mixed stands. However, mechanisms that may contribute to this effect are rarely studied, even though they are essential to assess the potential of species to cope with climate change. This study examined fine root overlap and the linkage between fine root and stem growth of European beech (Fagus sylvatica) growing in pure and mixed stands with Douglas fir (Pseudotsuga menziesii) or Norway spruce (Picea abies) at two different study sites in northwestern Germany.

欧洲山毛榉在花旗松和挪威云杉的纯林和混交林中根系重叠和地下生长的分配


立地条件和物种特性对纯林和混交林中树木的细根生长有综合影响。然而，可能促成这种影响的机制很少被研究，尽管它们对于评估物种应对气候变化的潜力至关重要。本研究在德国西北部的两个不同研究地点检查了生长在纯林和混交林中的欧洲山毛榉 （Fagus sylvatica） 与花旗松 （Pseudotsuga menziesii） 或挪威云杉 （Picea abies） 的细根重叠以及细根与茎生长之间的联系。
