Effects of abscisic acid on growth and selenium uptake in medicinal plant Perilla frutescens

The aim of the present study was to explore the effects of abscisic acid (ABA) on growth and selenium (Se) absorption of the medicinal plant, Perilla frutescens. A pot experiment was conducted to evaluate the effects of different ABA concentrations (0, 1, 5, 10 and 20 μmol/L) on the physiological ch...

description The aim of the present study was to explore the effects of abscisic acid (ABA) on growth and selenium (Se) absorption of the medicinal plant, Perilla frutescens. A pot experiment was conducted to evaluate the effects of different ABA concentrations (0, 1, 5, 10 and 20 μmol/L) on the physiological characteristics and Se absorption capacity of P. frutescens. Application of 5, 10 and 20 μmol/L ABA increased the shoot biomass of P. frutescens, and only 5 and 10 μmol/L ABA increased the root biomass. Application of 5, 10, and 20 μmol/L ABA increased the contents of photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid), superoxide dismutase activity, peroxidase activity, and soluble protein content of P. frutescens, and decreased the malondialdehyde content in P. frutescens. Only 5 and 10 μmol/L ABA used in the present study increased the catalase activity of P. frutescens. For the Se uptake, only 5 μmol/L ABA increased the Se content, Se extraction and Se bioconcentration factor of both roots and shoots. The findings of the present study indicate that 5 and 10 μmol/L ABA promotes the growth of P. frutescens, whereas 5 μmol/L ABA enhances the Se accumulation capacity in P. frutescens.
