Abstract

A pot experiment was conducted to study the effects of different concentrations of selenium (Se) on the growth and physiological characteristics of tomato seedlings. The results showed that the biomass, SOD activity, POD activity, CAT activity, soluble protein and soluble sugar content of tomato seedlings increased firstly and then decreased with the increase of Se concentration in soil at 0, 5, 10, 25 mg/kg, and reached the maximum value when Se concentration was 5 mg/kg, which was 3.63%, 53.99%, 30.54%, 40.79%, 14.20% higher than the control, respectively. MDA decreased with the increase of soil Se concentration. Pro showed an increasing trend, and the difference was significant, when Se concentration was 5 mg/kg, it was 68.37 % higher than the control. Therefore, Se can improve the physiological characteristics of tomato seedlings, promote its growth, increase biomass and enhance resistance. And the concentration of 5 mg/kg Se was the best.
