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...
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.
Influence of seed priming with Iron and/or Zinc in the nucleolar activity and protein content of bread wheat.
This work intends to study how seed priming with Fe and/or Zn affects the nucleolar activity in roots and the total soluble protein content in the flour of bread wheat cv. ‘Jordão’. in Protoplasma 256:763-775. Leia o trabalho completo aqui.
Seed priming with Iron and Zinc in bread wheat: effects in germination, mitosis and grain yield.
In this study, we investigated the effects of seed priming with different dosages (1 mg L−1 to 8 mg L−1) of Fe and/or Zn in germination, mitosis and yield of bread wheat cv. ‘Jordão’ when compared with control. in Protoplasma 255(4):1179-1194. Leia o trabalho completo aqui.
Effectiveness of Ascorbic Acid and Zinc as drought antagonists in bread wheat plants monitored by different DNA markers.
