为了解赤芝和沙柳的分布与菌根侵染的关系，在北海道萨摩内川河漫滩5个不同土壤条件下，研究了赤芝和沙柳幼苗的外生菌根和丛枝菌根质量和类型的变化。两种植物的根中均发现了高外生菌根和低丛枝菌根定殖。外生菌根侵染S.湿润桑迪或淤泥质土壤条件下的沙田柚与干燥砾石土条件下的沙田柚处于同一水平。相反，C.湿润桑迪地的乔木幼苗生长量低于干燥砾石地。在所有的研究地点，同样的三种形态类型的外生菌根占主导地位。
To understand the relationships between the distribution of Chosenia arbutifolia and Salix sachalinensis and their mycorrhizal colonization, changes in the quality and types of ectomycorrhizas and arbuscular mycorrhizas of the seedlings of two species were studied at five different sites with different soil conditions in the floodplain of the Satsunai River, Hokkaido. High ectomycorrhizal and low arbuscular mycorrhizal colonization were found in roots of both plants. Ectomycorrhizal colonization of S. sachalinensis in wet sandy or muddy soil conditions was at the same level as that in dry gravelly sites. In contrast, ectomycorrhizal colonization of C. arbutifolia seedlings was lower from wet sandy sites than that from dry gravelly sites. In all study sites, the same three morphological types of ectomycorrhizas were dominant.
