Abstract

One of the most diver effects of salinity on crop growth is the accumulation of toxic ions, particularly sodium, in plant tissue. Seed treatment with CALCIUM NITRATE may improve seed germination under SALT STRESS by reducing uptake of sodium and chloride ions. This research was conducted to study the effect of seed treatment with CALCIUM NITRATE on distribution of Sodium and potassium in seedlings of two RICE varieties under saline conditions. Therefore, a factorial experiment was performed based on Completely Randomized Design with 40 treatments and 3 replication. The treatments were consisted of different concentrations of CALCIUM NITRATE (0, 1, 5, or 10 mM), EGTA (calcium chelator, with 5 mM concentration), four levels of salinity (0, 50, 100, 150 mM of NaCl), and two varieties of RICE (Tarum and Gerdeh). The results indicated in both varieties, increasing the salt concentration caused a reduction in K+ concentration of root and shoot, but the Na+ concentration and Na+/ K+ ratio increased in shoot and root. The EGTA treatment induced a reduction in K+ concentration of root and shoot of both varieties, but Na+ content and Na+/ K+ ratio in these organs was increased by this treatment. In contrast, 10 mM of CALCIUM NITRATE under all salt concentration caused a reduction in sodium content and Na+/ K+ ratio of root and shoot, but potassium concentration in these organs was increased. In conclusion, Ca(No3)2 was effective to reduce the adverse effects of salinity in both varieties.
