Morphological types of arbuscular mycorrhizal (AM) fungi in roots of understorey plants were examined in three different Japanese deciduous broadleaved forests. In total, 43 species belonging to 33 genera from 27 families were examined for the morphological types of AM. The number of flowering plant species having Paris-type AM was greater than those having Arum-type AM in each plot. This tendency was more prominent in herbaceous plants than woody plants with nine species having Paris-type associations among ten herbaceous plant species examined. Therefore, it is suggested from the ecological point of view that Paris-type associations could be advantageous for the herbaceous understorey plants growing slowly in these environments. The influence of plant identity on the morphological types of AM was also discussed by arranging the plants examined with the morphological types in a current plant phylogeny scheme. In this study, some new records on the morphological types of AM in some new plant families were obtained including the first report of a typical Arum-type AM in gymnosperms.
在日本三种不同的落叶阔叶林中，对林下植物根系中丛枝菌根（AM）真菌的形态类型进行了研究。总共对来自27个科33个属的43种植物的AM形态类型进行了研究。在每个样地中，具有巴黎型AM的开花植物种类多于具有天南星型AM的种类。这种趋势在草本植物中比在木本植物中更为明显，在所研究的10种草本植物中有9种具有巴黎型共生关系。因此，从生态学角度来看，巴黎型共生关系可能有利于在这些环境中生长缓慢的林下草本植物。通过将所研究植物的形态类型按照当前植物系统发育图谱进行排列，还讨论了植物种类对AM形态类型的影响。在本研究中，获得了一些新植物科中AM形态类型的新记录，包括裸子植物中典型天南星型AM的首次报道。
