Arbuscular mycorrhizal (AM) colonization pattern in the roots of 4 plant species, Cryptomeria japonica (coniferous tree), Lindera triloba (deciduous shrub), Hydrangea hirta (deciduous shrub) and Leucosceptrum stellipilum (perennial herb), was investigated in a Japanese red cedar (C. japonica) forest on Mt. Ryuoh, central Japan. The AM colonization percentage was determined at different sampling sites along the slope. The AM colonization percentage in L. triloba was higher in the upper part of the slope than in the lower part. Topographic variations in soil nitrogen availability may have affected the AM colonization of the roots of L. triloba at the study site. However, other plants did not show such topographic changes in the AM colonization percentage. Microscopic observation of the morphological characteristics of AM colonization revealed that H. hirta and L. stellipilum were classified as Arum-type plants. In contrast, the mycorrhizas of C. japonica and L. triloba contained coiled hyphae to some extent as well as vesicles and arbuscules. Therefore, these two plants may be intermediate species between Arum- and Paris-type plants.
