Variations in proline, chlorophyll and mineral elements contents of wheat plants grown under salinity stress

Abstract

Variations in proline, chlorophyll, Na, Cl, N, P, K, Fe, Zn, Cu and Mn concentrations and growth of wheat plants (Triticum aestivum L. cv: Cakmak-79) grown under salinity stress were investigated in greenhouse conditions. For this purpose, 0, 25 and 50 mM NaCl were applied to the experimental soil taken from Aridisol lands. The growth of wheat plants was inhibited by salinity. The increased amount of NaCl applied to soil resulted in lower dry weight. Application of NaCl caused an increase on proline, Na, Cl, P, Zn and Mn concentrations, whereas decreases in chlorophyll, N, K, Fe and Cu concentrations were detected. © 2007 Asian Network for Scientific Information.
