18. Effect of silicon on enzymatic and non-enzymatic anti-oxidant defense systems in hydroponically grown cucumber plants (Cucumis sativus L.) under salt stress

The aim of the study was to investigate the ability of young hydroponically grown cucumber plants (Cucumis sativus L.) to recover from salt stress through Si-treatment. It was established that exogenous Si enhances the antioxidant capacity of plants, changes the activity of the antioxidant enzymes guaiacol peroxidase (GPX), syringaldazine peroxidase (SPX), the polyphenol content, antiradical activity (DPPH) and lipid peroxidation (LPO).
