Proline content, ion accumulation, cell wall and soluble peroxidase activities were determined in control and salt-treated calli (150mM NaCl) and whole plants (30 mM NaCl) of two rice cultivars (salt sensitive cv. IKP and salt tolerant cv. Aiwu). Under salinity, the highest accumulation of Na+, Cl- and proline occurred in calli, roots and younger leaves of cv. IKP, coupled with the highest decrease in K+ content; accumulations of Na+ and Cl- were restricted to older leaves in cv. Aiwu. Relative growth rates of calli and roots or shoots from both cultivars were not linked to peroxidase activities.
