Effect of Na2SO4 Application on the Growth, Yield and Cd uptake of Wheat

Abstract

Objective: Durum wheat accumulates more cadmium (Cd) in the grain than bread wheat. The aim of this study was to determine the effect of Na2SO4 salt on Cd uptake in wheat grain. Material and Method: The experiment was conducted by using durum wheat cultivar (Triticum durum, cvs. Balcalı-2000) under greenhouse condition. After 43 day of growth in the greenhouse, the shoots were harvested and dried at 70 ºC for determination of shoot dry matter production. It was also analyzed Cd concentration in shoot. The concentration of shoot Cd was measured by (ICP-OES, Varian, Australia). Results: Our results conclude that soil salinity increases Cd accumulation in the shoot even when soil Cd rates are very low. Furthermore, salinity in Cd-contaminated soils may accelerate cadmium transport to the shoot. Conclusions: The findings of this study revealed that shoot Cd concentration increased with increasing applied Cd and Na2SO4 rates.
