【 摘 要 】

Pot experiments were conducted to study the effects of different concentrations of selenium (Se) on growth and Se-rich characteristics Se of Perilla frutescens. The results showed that Se treatment had significant effect on growth and Se content. With Se concentrations increased, the biomass of P. frutescens significantly decreased. The root to shoot ratio increased firstly and then decreased, which reached the peak when Se concentration was 10 mg/kg. With Se concentrations increased, Se content increased and the difference between each treatment was extremely significant. In addition, the content of Se in leaf > root > stem. Translocation factor was on the rise as a whole, compared with control. Also, Se treatment had significant effect on the amount of Se accumulation in P. frutescens. With Se concentrations increased, the accumulation of Se showed different trends. However, as a whole, the accumulation of Se tends to increase. In addition, translocation accumulation factor showed a rising trend.
