Study on selenium accumulation characteristics of Lycopersicon esculentum, Solanum melongena and Solanum nigrum

The difference of three plants Lycopersicon esculentum, Solanum melongena and Solanum nigrum on the selenium accumulation were studied by a pot experiment. The results showed that selenium accumulation S. nigrum was the highest, L. esculentum was the second, S. melongena was the lowest. The root biomass of S. nigrum was 36.79% and 81.35%, respectively, higher than L. esculentum and S. melongena. The selenium content in the root and the shoot of S. nigrum were higher than L. esculentum and S. melongena by 16.50% and 13.35% and 35.76% and 35.76% respectively. In conclusion, the selenium accumulation of trentment S. nigrum is the best, L. esculentum followed it.
