Abstract

A factorial experiment based randomized complete block was conducted in order to investigation of two RICE (Oryza sativa L.) genotypes responses for Na+, K+, Ca2+, Mg2+, Cl-, Mn2+, P and total soluble sugars accumulation and compartmentation in leaves 3, 4, 5 and 6 to SALT STRESS. In estimation of the simple correlation between traits, dry weight was negatively correlated with Na+ and Cl-. The observed reduction in seedling growth was higher for IR29 (salt sensitive) than IR651 (salt tolerant). Salinity induced high Na+ and Cl- accumulation in leaves of both genotypes and in IR29 was more than IR651. The highest Na+ and Cl- concentrations were in third and fourth leaves of IR29. Total soluble carbohydrates concentration was increased only in leaves 5 and 6 of studied genotypes and had no change in leaves 3 and 4. Obtained results showed that under saline condition, reduction in Ca2+ concentration occurred in IR29 more than IR651, however, was observed in all leaves of both genotypes. There was no regular response of seedlings to salinity in relation to accumulation of Mg2+. Mn2+ and P concentrations had no changes under salinity. Under saline condition, K+/Na+ ratio was decreased in both genotypes but was higher in IR29. IR651 could to preserve high K+/Na+ ratio in sixth leaf than other leaves. Generally, IR651 could to accumulation toxic ions in older leaves for prevent damage to young leaves while high levels of these ions were accumulated in young leaves of IR29. Nacl also caused to imbalance for solutes concentration in leaves of both genotypes.
