This study was separated into three parts. First, effects of different endomycorrhizal inoculation on the colonization and growth of Syzygium cumini seedlings, grown in acid red soil of Laopi series. Second, effects of different mycorrhizal inoculation on the growth of Syzygium cumini seedlings grown in two different soil media, include acid red soil of Laopi series and coastal sandsoils of southern Taiwan. Finally, effects of different mycorrhizal inoculation on the growth of Syzygium cumini seedlings grown in different pH soils amendment with lime. The results of this study showed that tree height, diameter at root collar and dry weight of root, stem and leaf have increased significantly than those noninoculanted plant. In acid red soil of Laopi series, inoculation of Glomus spp. particularly G. aggregatum, G. etunicatum and G. mosseae were the best helpful for the growth performance, especially on the increase of phosphate absorption and biomass of Syzygium cumini seedlings. Under the different soil media in acid red soil of Laopi series and coastal sand soils of southern Taiwan, the results showed endomycorrhizal inoculation contribute the better growth of Syzygium cumini under the coastal sand soils. Using different amount of limes to adjust soils pH in acid red soil of Laopi series, the biomass of the control were not increased following the increasing pH. Contrarily, the plant biomass and nutrient contents of the mycorrhizal inoculation increased follow increasing pH. The effect of endomycorrhizae inoculation on the absorption of phosphorus were different according to the efficiency of endomycorrhizal species. Generally, the plants with inoculation of Glomus spp. had higher content of phosphorous.
