Aluminum toxicity is one of the major limiting factors of plant growth on acid soils. This study aims to indentify the biomass and Al content in the Phragmites australis seedlings tissues under the Al stress. Obtained results were as follows: (1) the fresh mass of roots, stems, and leaves decreased 7.00%, 6.11%, and 28.08% (10mg/L), 18.23%, 9.82%, 33.61% (50mg/L), 32.97%, 16.51%, 55.49% (100mg/L), 44.09%, 21.12%, 72.41% (200mg/L), 65.56%, 22.86%, 85.35%(300mg/L), and 78.56%, 23.53%, 93.22% (500 mg/L), compared with the CK (0 mg/L). The differences of roots fresh mass between the CK systems and low Al concentration medium (0-100 mg/L) were non-significant (p>;0.05), however, the differences between the CK systems and high Al concentration medium (100-500mg/L) were significant (p<;0.05), which indicated that the high concentration Al stress significantly restrict root, stems and leaves development of P. australis seedlings; (2) The dry mass of roots, stems and leaves of P. australis seedlings showed the same trend like fresh mass, which indicated that the high concentration Al stress significantly influence the biomass accumulation; (3) The Al content in the roots, stems and leaves of P. australis seedlings were also significantly affected by the external Al supply (p<;0.05) and the ranked order of Al content in plant tissues were as follows: roots >; stems >; leaves.
