| Popis: | This study investigated the contributions of mixed arbuscular mycorrhizal fungi (AMF) inoculum-i.e., mixed populations of indigenous mycorrhiza (Glomus intraradices, Glomus geosporum, Glomus mosseae) (IM) isolated from arsenic (As) contaminated soil and non-indigenous mycorrhiza such as G. mosseae (GM), which possess metal tolerance characteristics-and the addition of phosphate rock (PR) towards the uptake and accumulation of As by Pteris vittata (As hyperaccumlator) grown in As-contaminated soil. Regardless of As levels added to soil, plant growth was substantially improved in amended treatments when compared with the control. In addition, root surface area (0 mg/kg As: 15.2 cm2; 150 mg/kg As: 16.9 cm2; 300 mg/kg As: 20.7 cm2), chlorophyll contents (0 mg/kg As: 1.16 mg/g; 150 mg/kg As: 1.46 mg/g; 300 mg/kg As: 1.81 mg/g) and As translocation factor (0 mg/kg As: 0; 150 mg/kg As: 4.29; 300 mg/kg As: 5.22) in P. vittata of PR+IM/GM were also increased. Such combination could further enhance plant growth (indicated by higher N, P and chlorophyll contents) and As uptake by P. vittata. |
