One hundred soil samples from sites in North, Centre and West of Spain were examined for their capacity to induce nodules in alder (Alnus glutinosa) and bog myrtle (Myrica gale). Soils from A. glutinosa communities particularly from places where Myrica was absent, were checked for their infectivity towards M. gale. There was a good correlation between the results, since there was not one single sample which could induce nodules in Myrica which did not do the same in alder. The nodules formed on M. gale plants grown in soils collected from alder habitats showed acetylene-reducing activity at a level comparable to that described in the literature, in the case of other Myrica species. Considering together the results now obtained and in previous work, the possibility of cross-inoculation between M. gale and A. glutinosa, is again put forward and it is thus held that no specificity can be assigned, for the time being, to the respective endophytes.
对来自西班牙北部、中部和西部的100份土壤样本进行了检测，以评估它们诱导桤木（欧洲桤木）和杨梅形成根瘤的能力。对来自欧洲桤木群落的土壤，特别是来自没有杨梅的地方的土壤，检测了它们对杨梅的感染性。结果之间存在良好的相关性，因为没有一个样本能够诱导杨梅形成根瘤而不能在桤木上形成根瘤。在从桤木栖息地收集的土壤中生长的杨梅植株上形成的根瘤显示出乙炔还原活性，其水平与文献中描述的其他杨梅物种的情况相当。综合考虑目前获得的结果和以前的研究工作，再次提出了杨梅和欧洲桤木之间交叉接种的可能性，因此目前认为暂时不能赋予各自内生菌特异性。
