Soil salinity leads to serious productivity loss by activating a series of metabolic reactions. The static nature of the plants necessitates the activation of complex metabolic activities including antioxidant pathways, especially the scavenging of reactive oxygen species (ROS). In the present study, three rice cultivars, traditionally grown in the Kaipad rice system were selected to characterise their salt tolerance compared to the salt tolerant variety Vytilla-2. The 21 day old seedlings of the Kaipad rice varieties and Vytilla-2 were subjected to salt stress, ranging from 25 mM to 150 mM NaCl. The leaf samples were collected at an interval of 7, 14 and 21 days of salt stress and evaluated for enzymatic and non-enzymatic antioxidants and ascorbate-glutathione cycle enzymes.
