Abstract

Salinity is one of the major environmental constraint that restricts crop growth and yield. Rice (Oryza sativa L.), one of the major staple crops, consumed by more than half of the world's population is regarded to be salt sensitive. Salt stress in plants occurs in two phases over time, i.e. osmotic and ionic phase. The application of salt stress also plays an important role in deciding whether the crop is responding to salt stress or salt shock. Further, the response to salinity stress is specific to the crop developmental stage. Hence an experimental approach that takes into account these factors (1) delineating the two phases (2) salt stress vs salt shock and (3) developmental stage is crucial in exploring salt determinants in rice. The review presented here examines the data in these aspects and further, provides various approaches in light of the current understanding. The focus is on the different approaches available to researchers including Petri plate based method, hydroponics and soil based approaches for screening and understanding the plant response to salinity. The review will be helpful for researchers to choose an appropriate experimental procedure for studying tolerance to NaCl stress using rice as a model system in the laboratory.
