The role of antioxidative system in plants adaptation against salt stress is discussed. The causes of secondary oxidative stress at influence of salinity on plants are considered. The contribution of various enzymatic and non-enzymatic antioxidants to plants defense against the negative consequences of salt stress is analysed. The considerable attention is paid to the proline as to the multifunctional protective compound performing osmoprotective and antioxidative functions at the same time. Possible mechanisms of functional interaction of constituents of plants protective systems are discussed. Data on the role of phytohormones and components of cellular signalling are provided in the induction of antioxidative system.

Key words: salt stress, reactive oxygen species, secondary oxidative stress, antioxidant enzymes, osmolytes, salt resistance induction
