摘要： A pot experiment was conducted to compare the differences of growth, absorption, transportation and accumulation of selenium (Se) in three vegetables differing in Se transport distances, including cucumber (Cucumis sativus L.), tomato (Solanum lycopersicum L.) and radish (Raphanus sativus L.) exposed to soil Se levels (0, 1.0, 5.0, 10.0 and 15.0 mg center dot kg(-1)). Results showed that soil application of Se (<10 mg center dot kg(-1)) remarkably promoted the growth of all three vegetables by increasing plant dry weights by 5.46% to 58.2% compared to the control without Se treatment. Se concentration and accumulation in roots, stems and leaves increased with the increase of soil Se level and reached the highest when applied at 15 mg center dot kg(-1). At the same Se level (<= 15 mg center dot kg(-1)), Se concentration in roots, stems and leaves of radish was higher than tomato and cucumber. Se enrichment and its translocation factors for radish were also significantly higher than tomato and cucumber. Compared to tomato and cucumber, radish is more suitable for selenium-rich vegetable cultivation under soil applied Se <= 15 mg center dot kg(-1). (C) 2018 Friends Science Publishers
