Abstract
Pot experiment was conducted to investigate the dry weight, selenium extraction and accumulation of roots, stems, leaves and shoots of Capsella bursa-pastoris under the conditions of 0, 5, 10, 25, 50, 75 and 100 mg/kg. The results showed that selenium at the concentrations of 5, 10 and 25 mg/kg could promote the growth of C. bursa-pastoris, and the selenium content of each part of C. bursa-pastoris increased with the increase of selenium concentration. The transfer factor increased at first and then decreased, the maximum was 0.474. The accumulation of selenium increased at first and then decreased with the concentration increasing, and reached the maximum at 25 mg/kg.
