Abstract:

Cadmium (Cd) is a toxic element for plants, animals and humans and it is an ever increasing environmental concern. Genetic differences and availability of other elements in soil are the significant factors affecting plant Cd uptake from soils. Zinc (Zn), nitrogen (N) and sulfur (S) deficiencies are the widespread common deficiencies observed both in world and Turkish soils. This study was conducted to determine Cd accumulation capacities of 13 different genotypes of canola (Brassica napus ssp. oleifera L.) under Zn, N, and S deficiencies and treatments. Results revealed higher shoot Cd accumulation levels under Zn-deficient conditions than under Zn-sufficient conditions. Zinc treatments significantly decreased shoot Cd accumulation levels of plants. With regard to Cd concentrations of genotypes, decreasing effect of N-deficient conditions was higher than the effect of N-sufficient conditions. Sulfur treatments did not have any significant effects on Cd concentrations in shoots of plants. The results of the study also showed that there were significant differences in Cd accumulations in shoot of the canola genotypes.
