【 摘 要 】

To study the effects of different concentrations of selenium on the selenium accumulation characteristics of Solanum alatum, we used the pot experiment to study effects of different selenium concentrations (0, 5, 10, 25, 50, 75, 100 mg/kg) on the biomass and selenium content of S. alatum. The results showed that all concentrations of selenium reduced the biomass of S. alatum. The biomass of S. alatum decreased with the increase of selenium concentration. In addition, with the increase of Se concentration, the Se content of S. alatum roots and stems increased. The Se content of S. alatum leaves and shoots increased first and then decreased with the increase of Se concentration. The selenium accumulation of each part of S. alatum increased first and then decreased with the increase of selenium concentration. Selenium accumulation in S. alaum shoots and whole plants were in the ranges of 0.503-13.915 μg/plant and 1.089-18.319 μg/plant respectively under the selenium stress. In all treatments, when the concentration of selenium was 10 mg/kg, the selenium accumulation of each part of S. alatum was the highest. Therefore S. alatum is most suitable for planting at a selenium concentration of 10 mg/kg.
