Selenium in bread and durum wheats grown under a soil supplementation regime in actual field conditions, determined by cyclic and radiochemical neutron activation analysis.
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). in Journal of Radioanalytical and Nuclear Chemistry 304 (1): 139-143.

The INIAV-Elvas wheat collection has always been an invaluable asset in studies of agronomic and/or genetic development of wheat lines, as well as providing a frame of reference for the nutritional evolution of Portuguese wheat crops. This work addresses the status of selenium (Se) in a pool of 46 accessions of bread wheat. in Crop...
Cereals are far from being the main sources of Se on a content basis, but they are likely the major contributors to intake on a dietary basis. To assess their potential to assimilate and biotransform Se, bread and durum wheat were enriched with Se through foliar and soil addition at an equivalent field rate of...
Sequential zinc and iron biofortification of bread-wheat grains: from controlled to uncontrolled environments.
The development of knowledge on bread wheat (Triticum aestivum L.) biofortification in zinc (Zn) and iron (Fe), related to its potential agronomical use and the nutritional and technological implications, is becoming important to strategies for improving human nutrition. In this context, we studied the accumulation of Zn and Fe in grains, considering potential uptake and...
Selenium supplementation of Portuguese wheat cultivars through foliar treatment in actual field conditions.
The present paper focuses on the ability of bread and durum wheat—Triticum aestivum L. and Triticum durum Desf., respectively—to accumulate Se after supplementation via a foliar-addition procedure. in J Radioanal Nucl Chem 297 (2): 227–231. Leia o trabalho completo aqui.
Selenium determination in cereal plants and cultivation soils by radiochemical neutron activation analysis.
Cereals are by far the most significant agricultural crops, not only on a gross tonnage basis, but also by what they represent in terms of energy supply and dietary intake for human nutrition worldwide. Portugal is no exception to such pattern. The Portuguese situation is difficult to assess though, due to scarce information and lack...
Determination of selenium in bread-wheat samples grown under a Se-supplementation regime in actual field conditions.
This paper focuses on determining the ability of bread wheat to accumulate selenium after supplementation. One of the methods for supplementing this element in plants is foliar application with selenium solutions. in Journal of Radioanalytical and Nuclear Chemistry, 291: 231-235.

Radiotracing selenium in bread-wheat seeds for a Se-biofortification program – An optimization study in seed enrichment.
This study addresses the protocol for preparing Se-enriched wheat seeds, with the specific purpose of optimizing the administration of Se to the seeds prior to sowing. in Journal of Radioanalytical and Nuclear Chemistry, 291: 193-195. Leia o trabalho completo aqui.
