Farklı Tuz Uygulamalarının Makarnalık (Triticum duum L.) Buğdayda Kadmiyum ve Çinko Alımı Üzerine Etkisi

Abstract

Cadmium (Cd), an important environmental polluter reaching into soils from different sources, is not an essential element in animal and human nutrition. Cadmium, when present in high concentrations, is an element with toxic effect to humans, animals and plants. One of the important factors affecting Cd accumulation in plants is salinity status of the soils. In this study, it was determined how different salts effected Cd accumulation in plants. 
 When increasing rates of NaCl, Na2SO4 and CaCl2 applied into the soil, it was determined that Cd accumulation capacity of the plants increased only with the forms of Cl-1 salts, particularly with NaCl. It was found that, among different salts applied with increasing ratios (NaCl, Na2SO4 ve CaCl2), NaCl salt remarkably increased green part Cd concentration. With comparing the effects of different salts on Cd uptake, green part Cd concentration in the Cl-1 salt applied condition was higher than those of the plants treated with SO4-2 salt. The Cd concentration of the plants was affected differently when the salt was applied as NaCl and CaCl2 forms. The increasing effect of chlorine on Cd concentration mostly occurred when it was applied as Na form. With the present of calcium, the increasing effect of Cl on Cd uptake was less comparing to Na ion. In conclusion, the application of Cd and different salts with increasing rates decreased dry matter yield of green part but increased Cd accumulation by plant.
