Rice is generally a salt-sensitive crop. However, many varieties show variations in salt. The response of four rice genotypes against 0, 8, 12, and 16 dSm-1 salinity levels was studied at the early seedling growth stage. Data for protein metabolism and enzyme activities were analyzed statistically. Salinity decreased the protein content, peroxidase, and catalase activity but increased, proline content, and amino acids in all genotypes and the magnitude of reduction increased with increasing salinity stress. Rice genotypes Sabour Surbhit, Sabour Ardhajal, Rajendra Kasturi and Bhagalpur Katarani showed greater salt tolerance and susceptibility during germination. Sabour Surbhit and Sabour Ardhajal are tolerant and Rajendra Kasturi & Bhagalpur Katarani are susceptible rice genotypes against salt stress. The result suggested that Sabour Surbhit, Sabour Ardhajal, Rajendra Kasturi, and Bhagalpur Katarani might be used for further study of the salinity effect on growth processes and its physiological consequences at an advanced stage of growth.
