Salinity is one of the major yield-limiting abiotic factors. Under stress conditions, reactive oxygen species (ROS) are produced in plants, which cause reduced productivity and yield. These ROS are scavenged by various bioactive compounds like phenolic acids inducing tolerance in plants to mitigate abiotic stress conditions. In this chapter, the authors have discussed the scientific information related to plants’ response under salinity stress conditions, the role of osmoprotectants (polyols, glycine betaine, and proline), polyamines, hormonal modulation, and changes in the concentration of bioactive compounds. Plants undergo several physiological and biochemical changes under salinity stress and show variable expression of the bioactive compounds under stress conditions. Osmoprotectants like glycine betaine and proline are also being applied exogenously to induce tolerance in salt-sensitive plants in order to increase plant productivity.
