Quantification of loss in oil seed rape yield caused by delayed sowing date in a Mediterranean environment.
Rapeseed acreage has been increasing fast in the last few decades and cultivated areas have expanded into lower latitudes because of the high value of its seed. This work evaluates the effect of date of sowing and nitrogen (N) fertilization on crop productivity and N use efficiency in a Mediterranean environment. in Archives of Agronomy...
Screening of worldwide cowpea collection to drought tolerant at a germination stage
The main objective of this study was to evaluate the effect of drought on seed germination and seedling emergence of cowpea genotypes, in order to screen the most tolerant genotypes. in Scientia Horticulturae, Volume 247: 107-115. Leia o trabalho completo aqui.
Evaluating stress responses in cowpea under drought stress
Drought impact on plants is an increasing concern under the climate change scenario. Cowpea (Vigna unguiculata L. Walp.) is considered as one of the most tolerant legume crops to drought, being the search for the best well-adapted genotypes crucial to face the future challenges. Different approaches have been used for differentiating plant responses to drought...
Biochemical, physiological and genetic analysis of aluminum tolerance of different rye species.
Rye (Secale cereale L.) is one of the most Al-tolerant cereal with a valuable genetic background for breeding purposes. Wild relatives (Secale spp.) have great importance once they can provide new sources of genes related to this trait. Different cellular disorders possibly related to Al tolerance/toxicity were observed through histochemical root staining methods in cultivated...
Potential of advanced breeding lines of bread-making wheat (Triticum aestivum L.) to accumulate in grain minerals (Ca, Fe, Mg and Zn) and low-phytates concentration under Mediterranean Conditions.
About 3 billion people may suffer from micronutrient deficiency such as Ca, Fe, Mg or Zn, caused not only by a mineral deficiency in staple food but also by a high content of phytates which bind those minerals and inhibit their absorption. With the aim of evaluating the potential of new cultivars of bread‐making wheat...
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.
Adaptabilidade de trigo em contexto de alterações climáticas
A fenotipagem de alto débito permite identificar parâmetros funcionais diretamente relacionados com o comportamento varietal em condições de stress climático. É uma ferramenta importante no moderno melhoramento de plantas uma vez que permite complementar os critérios habitualmente utilizados, aumentando a eficiência de seleção. in Vida Rural, Nº 1843, Ano 66, dez 2018/jan 2019, 40-41 Leia...
We might have got it wrong: Modern wheat is not more toxic for celiac patients
If there is a disease in which many myths are part of the daily lives of both patients and clinicians as well as researchers, this must be celiac disease. Here, we discuss the possibility that modern wheat varieties used by man do not have led to the increased prevalence of celiac disease. in Food Chemistry,...
Effect of in situ gluten-chitosan interlocked self-assembled supramolecular architecture on rheological properties and functionality of reduced celiac-toxicity wheat flour
A new technology for reducing wheat flour toxicity for celiac disease patients through the in situ formation of gluten-chitosan interlocked self-assembled supramolecular architecture was developed. To have a deeper insight into the microstructure of this new molecular organization and its impact on the dough properties, its small and large deformation rheological properties and the macromolecular...
