The relative abundance of ectomycorrhizal (ECM) roots in pure and mixed stand compositions of Dryas octopetala, Salix repens and Arctostaphylos uva-ursi grown in Scottish coastal arctic/alpine relict habitat was described through ECM morphotyping and comparisons of fungal internal transcribed spacer sequences. Neither specific ECM morphotypes nor the morphotype communities were found in association with any stand compositions. The proportions of the ECM roots on S. repens, however, were significantly less in pure stand and were further decreased in mixed with A. uva-ursi. Possible factors contributing the reduction, including the effects by other host species grown in proximity, are discussed.

根据苏格兰北极/高山沿海遗迹植被中不同寄主植物的成分,外生菌根的比例会有所不同
菌根(ECM)的根中的纯的和混合组合物的立场的相对丰度仙女octopetala,柳草和熊果在苏格兰沿海北极/高山遗栖息地生长是通过ECM描述morphotyping和真菌内转录间隔区序列的比较。没有发现特定的ECM形态型和形态型群落与任何林分组成有关。然而,在纯林中,ECM根在白麦链球菌上的比例显着降低,而在与农杆菌混合时则进一步降低。讨论了导致减少的可能因素,包括附近生长的其他寄主物种的影响。
