Abstract

The main objective of this research was conducted with reduction of SALINITY stress by CALCIUM NUTRITION on seedlings of WHEAT. The Zagros, Opaata/bow and Pegol Seri genotypes were selected for this aim. The plants were transplanted in hydroponics culture system with Hogland nutrient solution in growth chamber under control condition. The treatments were included 0 and 100 mM NaCl each one along with 2.5,5 and 10 mMCa2+. SALINITY induced the significant reduction in total dry weight and leaf area but Opata/bow genotype by 18 percent and Pegol Seri genotype by 14 percent increase of dry weight in 5 mM CaCl2 treatment with SALINITY indicated significant lower decrease of dry weight and leaf area than 2.5 mMCaCl2 treatment. In spite of significant increase of Na+ concentration by SALINITY, 5 mM CaCl2 treatment with SALINITY caused significant reduction on Na+ concentration in roots of all genotypes and shoots of Opata/bow genotypes in the proportion of other calcium treatments. SALINITY induced decrease of K+ uptake. However, 5 mMCaCl2 treatments improved significantly the K+ concentration in all genotypes. Though the Ca2+ concentration decrease under SALINITY, addition of CaCl2 to culture solution occasioned to increase of Ca2+ concentration in all genotypes. The results indicated that 5 mM CaCl2 reduced the toxin effects of SALINITY especially in Opata/bow genotype. Consequently, the protein content was increased in 5 mMCaCl2 treatment in compare to other calcium treatments. Further experiments are recommended on reproductive stage and other genotypes of WHEAT.
