LCA of sunflower oil addressing alternative land use change scenarios and practices

Sunflower oil is one of the leading food oils, recently also used for biodiesel production, mainly in southern European countries. This paper presents a Life-Cycle Assessment of sunflower oil produced in Portugal. Two alternative agriculture practices (irrigated and non-irrigated cultivation) were assessed.

Al toxicity mechanism in tolerant and sensitive rye genotypes.

Rye (Secale cereale L.) plants have high tolerance to Al, and become unique tools to study Al-toxicity and tolerance mechanisms. To better understand if and how Al-induced root growth inhibition is related with root histological differentiation, nutrient balances and cell cycle dynamics, tolerant (AT6) and sensitive (AS6) rye lines were exposed for 24 h to...

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.

Genetic diversity in Old Portuguese durum wheat cultivars assessed by retrotransposon-based markers.

Retrotransposon-based markers, such as the inter-retrotransposon-amplified polymorphism (IRAP) and the retrotransposon microsatellite-amplified polymorphism (REMAP) are highly informative, multilocus, and reveal insertional polymorphisms among plant individuals. These markers have been used for evolutionary studies, genetic diversity assessment, DNA fingerprinting, genetic mapping linkage, and for the detection of genetic rearrangements induced by polyploidization. In this study, we...

Polymorphism of the storage proteins in Portuguese rye (Secale cereale L.) populations.

Currently, due to the abandonment of traditional agricultural practices and the decline of rye production in Portugal, there is a need to assess the genetic diversity of rye in order to preserve its biodiversity. Furthermore, a greater knowledge of rye secalins is important for rye bread‐making quality and other crop breeding purposes. The genetic variation...
