摘要： We investigated arsenic (As) accumulation and distribution in four different tissues of maize, leaves, stems, bracts, and kernels. For these analyses, we used 122 elite inbred lines, which were grown in an As-contaminated area in China. The agricultural soil at the study site is highly As-contaminated (11.02+or-0.95 mg As kg soil-1) because of excessive use of As-rich surface water for irrigation. The As concentration in the leaves was significantly positively correlated with that in stems and kernels, and the As concentration in the stems was significantly positively correlated with that in the kernels. In the 122 inbred lines, the highest average As concentration was in the leaves, followed by the stems, the bracts, and then the kernels. The range of As concentrations in leaves, stems, bracts, and kernels of the 122 inbred lines was 0.13-1.48, 0.017-0.145, 0.013-0.131, and 0.0001-0.0408 mg As kg-1, respectively. The inbred lines with low As concentrations in the kernels perhaps could be used as a parent to select an elite hybrid with low As concentration for decreasing the As damage for people and animal.
