The Distribution and Association of Endomycorrhizal Fungi in Bamboo Forest (Phyllostachys pubescens Mazel) of Chi-Tou Area in Taiwan I. A. Preliminary Investigation on Endomycorrhizae in Bamboo Forest

In the bamboo forest, 34 species belonging to 21 families of ground covers including bamboo (Phyllostachys pubescens) were investigated, and 28 were found to be VA mycorrhizous. Among 21 families as mentioned above, Urticaceae and Polygonaceae have been thought as uneasily forming VAM. But in this investigation, one species of Urticaceae, Gonostegia hirta and two species of Polygonaceae, Polygonum hydropiper, and P. thunbergii seems to be heavily infected by VA mycorrhizal fungi, Among the rhizosphere of ground covers in bamboo forest 14 species of VAM fungi were recovered including five new recorded species from Taiwan and two new species. P. pubescens was found to non-VA mycorrhizous and infected by septate mycelia with perpendicular branches, probably by a species of Form-genus Rhizoctonia.
