The average Se contents in root, stem, leaf and seed of corn were estimated to be 4.36±3.27mg/kg, 3.08±2.24 mg/kg, 9.74±7.62mg/kg, and 8.07±5.02mg/kg, respectively. The research results show that there is a significantly positive correlation between corn selenium and soil selenium, and thus according to the distribution of Se in corn, three subregions can be divided in Yutangba. The content of selenium in corn is controlled by that of soil. A little variation in selenium content in soil will lead to a considerable corresponding variation in corn. So it is deduced that the organs that contain relatively high Se in plants may be used as a sensitive selenium indicator of Se levels in the environment.展开更多
