| Popis: | The present study investigates the appliance of cadmium (Cd) noxiousness and damage to nutrient concentration in sunflower hybrids, FH-533 and Hysun-33, as well as the role of natural and synthetic chelator’s oxalic acid (OA) and ethylene triamine tetraacetic acid (EDTA) respectively in reducing the Cd toxicity in sunflower plant. Sunflower, known as heavy metal phytoextractor, was grown in soil artificially contaminated with soluble salt CdCl2 at 250 ppm and 450 ppm. Pot experiment was conducted in a complete randomized design with three replicates for cadmium metal, chelating agents and sunflower hybrids at seedling, vegetative and reproductive stages. Application of Cd of 250 ppm and 450 ppm imposed the negative effect on shoot and root dry biomass by directly or indirectly disturbing the nutrient uptake. Maximum growth and nutrient uptake were observed when chelators (EDTA and OA) were applied alone respectively. In Cd contaminated soil the application of EDTA proved helpful in ameliorating the toxic effect of Cd250 on nutrient content of both sunflower hybrids as compared to Cd450, the Hysun-33 showed better results in terms of K, Ca, Fe, Zn, P, N as compared to FH-533, so it can be cultivated on Cd adulterated soil for better yield. The presented results offer a novel solution for optimization of sunflower cultivation on soil affected by Cd, as well as for increased health-promoting nutrients of sunflower.
