| [influence of soil factors on species diversity of arbuscular mycorrhizal (am) fungi in stipa steppe of tibet plateau]. | this study was based on the isolation and identification of arbuscular mycorrhizal (am) fungi collected from the alpine stipa steppe of north tibet, and focused on the influence of soil texture, ph, organic matter, and available p on the spore density, isolation frequency, relative abundance, importance value, species diversity, and species evenness of the am fungi. in the rhizosphere soil of the steppe, a total of 15 species am fungi were isolated and identified, including 9 species of glomus, ... | 2010 | 20707110 |
