Abstract

A pot experiment was conducted to study the selenium accumulation characteristics of tomato seedlings under different concentrations of selenium. Four treatments were used in the experiment: soil was constructed by adding 0, 5, 10, 25 mg/kg exogenous selenium. The fresh weight and selenium contents in roots, stems and leaves of tomato seedlings were determined. The results showed that the selenium contents of tomato seedling organs increased with the increase of soil selenium concentration. The biomass of roots, stems and leaves of tomato seedlings increased firstly and then decreased with the increase of soil selenium concentration, and reached the maximum value when the soil selenium concentration was 5 mg/kg, which was 94.59%, 33.16% and 40.09% higher than the control, respectively. However, the biomass decreased significantly when the soil selenium concentration reached 25 mg/kg, which was 52.51%, 67.42%, 70.14% lower than the control. Therefore, low concentration selenium could increase the biomass and promote the growth of tomato seedlings. However, the high concentration of selenium could reduce the biomass of tomato seedlings, inhibit the growth of tomato seedlings, and produce toxic effects in severe cases. The concentration of 5 mg/kg Se was the best.
