Plant Growth and Antioxidative Enzymes in Sunflower Supplemented With Selenium

The use of soil additives such as selenium can positively influence the antioxidative system plants, making them more tolerant to abiotic stresses. aim this work was evaluate concentration sodium selenite or selenate applied substrate that causes improve in plant growth and enzyme activities sunflower plants. treatments were divided in: control (absence selenium); 0.2 mg L-1 selenate; 0.4 0.8 selenite; selenite. analysis Shoot Dry Mass (SDM) production antioxidantive enzymes: Ascorbate Peroxidase (APX), Guaiacol (GPX) Catalase (CAT) performed. For SDM APX caused higher values. CAT showed greater activity received than treatment. GPX superior selenate, It concluded promoted improvements antioxidant shoot dry mass
