摘要

The effect of soil chemical properties on the diversity and colonization of arbuscular mycorrhiza (AM) varies among ecosystems. This study was conducted to assess and compare the abundance of AM in a rehabilitated forest and a logged-over forest soilusing the most probable number and spore number methods. Glomus (71.7%-82.1%) and Acaulospora (17.4%-19.5%) were found to be abundant in both sites, while Gigaspora was found only in the logged-over forest. The abundance of AM in the rehabilitated forestbased on the spore count was significantly higher than in the logged-over forest by a 6-fold difference. Furthermore, root colonization in the rehabilitated forest was found to be almost 9-fold higher than in the logged-over forest. Such differences arelinked to the soil chemical properties. The addition of organic matter during forest rehabilitation activity had created favorable conditions for AM sporulation. Soil P in both forests was positively related to the spore count (r > 0.68, P < 0.001) while the most probable number (MPN) was negatively influenced by soil K (r = -0.632, P < 0.01). In conclusion, this study showed that soil chemical properties have a direct effect on the abundance of AM.
