Three rice cultivars namely, C4-63G, PB76-TB188 and IR8 were grown in RS-17 culture solution under four levels of NaCl to determine growth, sodium and chloride content, concentration of the cell sap and the activity of the RuDP carboxylase and PEP carboxylase. Growth of the three rice cultivars in terms of plant height, root length, number of tillers, fresh and dry weight of shoot and root increased in 0.1 percent NaCl treatment but decreased in 0.3 percent NaCl level. Increasing NaClconcentration in the culture increased the number of dead leaves of the three cultivars, the sodium and chloride concentration in the shoot. IR8 exhibited the best growth and highest proline content in the leaf blades.
