Proteaginosas, o regresso do grão-de-bico.
A grande escassez global de fontes proteicas, concretamente para os alimentos compostos para animais, torna a Europa muito dependente de matérias-primas oriundas de países terceiros como é o caso típico da soja. O panorama em Portugal é ainda mais preocupante, havendo necessidade de importar cerca de 70 000 t/ano, para alimentação humana. in Vida Rural....

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.

Selenium characterization of the Portuguese bread-wheat archival collection.
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...
Characterization of selenium-enriched wheat by agronomic biofortification.
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...
Influence of year and sowing date on bread wheat quality under Mediterranean conditions.
Grain quality is an essential component in wheat breeding programs since influences the commercial value of wheat. This study was conducted to determine the effects of genotype, season and sowing date on quality parameters of seventeen bread wheat commercial varieties and three advanced lines from Portuguese Wheat Breeding Program (Plant Breeding Station, Elvas, Portugal) under...
Physiological Responses to Drought in Four Developed Triticum aestivum Groups.
There is an increasing need to characterize germplasm diversity in order to highlight drought tolerant genotypes and to assist Portuguese wheat breeding programs. Bread wheat (Triticum aestivum) varieties were selected from four different evolutive and/or breeding groups: ancient landraces, traditional varieties, modern currently used and advanced lines. The aim of this work was to identify...
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...
Adaptação às alterações climáticas – Compreender e diminuir o yield gap no trigo mole e no trigo duro.
O INIAV, a ANPOC e o ARVALIS – Institut du Végetal (organismo francês de investigação agrícola financiado e gerido por agricultores) desenvolvem em conjunto, desde 2011, um programa de investigação com os objetivos de compreender e reduzir o yield gap das culturas de trigo mole e trigo duro em clima mediterrânico do sul da Europa;...
