Soil salinity is the one of the most important abiotic factors influencing the growth, development and yields of crops. However, it is difficult to determine exact concentrations of salt which cause soil salinity. Salinity threshold levels depend on a crop species, variety, developmental stage and environmental factors. This paper presents the results of an experiment on the effect of different soil concentrations of NaCl soil on several oxidation stress parameters, such as catalase and peoxidase activity, content of ascorbic acid, phenols and flavonoids in bean plants. A laboratory pot experiment was carried out on samples of light silty loam containing 1.2% of humus. Pots were filled with 1 kg soil samples each, to which NaCl solution was added in doses 10, 30 and 50 mM kg-1. Each pot was seeded with 7 seeds of cv. Aura bean. The plants grown in soil without NaCl were the control. On days 14, 21 and 28 green parts of plants were collected for determinations of catalase and peroxidase activity by colorometry as well as the content and flavonoids, phenols, ascorbic acid and chloride concentration by Mohr’s method. The results show that chloride concentration in bean plants increased at higher of NaCl concentration in soil. The activity of the antyoxidative enzymes such as catalase and peroxidase in bean plants, on sampling days, was higher as the chloride concentration in plants increased. Non-enzymatic antioxidants: flavonoids, phenols and ascorbic acid content during the experiment showed different changes with relation to the chloride content, but in all the trials ascorbic acid content was significantly positively correlated whereas the content of phenols was significantly negatively correlated with the chloride content in plant tissues.
