Selenium in bread and durum wheats grown under a soil-supplementation regime in actual field conditions, determined by cyclic and radiochemical neutron activation analysis(Article)

Journal of Radioanalytical and Nuclear Chemistry

Journal Article

This work focuses on the ability of bread and durum wheat to accumulate selenium (Se) via a soil-addition procedure at sowing time. Total Se in mature-grain samples was determined by neutron activation analysis (cyclic and radiochemical). Results show that Se-supplementation at the top rate (100 g Se ha−1) can increase Se contents up to 2, 16, 18 and 20 times for Jordão, Roxo, Marialva and Celta cultivars, respectively, when compared to their unsupplemented crops. These findings do not preclude the need for weighing up an eventual trade-off between agrochemical costs, field logistics and Se recovery for alternative Se-biofortification methods. © 2014, Akadémiai Kiadó, Budapest, Hungary.
