Effects of Different Selenium Concentrations on Eco-Physiology of Lactuca sativa

The Effects of six selenium concentrations (0, 5, 10, 25, 50, 75, and 100 mg/kg) on eco-physiology of Lactuca sativa were conducted by a pot experiment. The result showed that with the Se concentration increased, the biomass, photosynthetic pigment contents and antioxidant enzyme activities of L. sa...

Description
Summary:The Effects of six selenium concentrations (0, 5, 10, 25, 50, 75, and 100 mg/kg) on eco-physiology of Lactuca sativa were conducted by a pot experiment. The result showed that with the Se concentration increased, the biomass, photosynthetic pigment contents and antioxidant enzyme activities of L. sativa seedlings all increased first and then decreased, and reached maximum at 5 mg/kg. Compared with control, shoot fresh weight, SOD activity and POD activity showed significant difference. At 100 mg/kg of Se concentration, the biomass, photosynthetic pigment contents and antioxidant enzyme activities of L. sativa seedlings all reached minimum and except SOD activity all showed significant difference.
