(ROS) and creation of oxidative stress, where ROS rapidly attack all kinds of
biomolecules such as nucleic acids, proteins, lipids and amino acids and lead
to abnormal metabolic function. Salicylic acid reduces the effects of oxidative
stress. In this research, first, seeds were cultured in the pots containing
perlite and then they were put in a growth room under controlled conditions
at 27±2 and 23±2°C in light (16 h) and dark (8 h) conditions,
respectively with luminous intensity of 15 klx and moisture of 75%. Five concentrations
of NaCl including 0, 25, 50, 75 and 100 nM and 4 concentrations of salicylic
acid including 0, 1.5 and 1.5 mM were used. Then, peroxidation rates of lipids,
ascorbic acid and dehydroascorbic acids were measured to study the effects of
oxidative stress. High salinity significantly increased malondealdehyde rate.
At different salinity levels, a decrease in other aldehydes was found and salicylic
acid decreased its effect in most treatments. Content of ascorbic and dehydroascorbic
acids increased by salinity and its salicylic acid was reduced.]]>Borsani, O., V. Valpuesta and M.A. Botella,2001Arabidopsis seedlings.]]>12610241030Dat, J.F., H. Lopez-Delgado, C.H. Foyer and I.M.
