Foliar Spraying with ZnSO4 or ZnO of Vitis vinifera cv. Syrah Increases the Syn...
Daccak, Diana; Marques, Ana Coelho; Pessoa, Cláudia Campos; Coelho, Ana Rita F.; Luís, Inês Carmo; Brito, Graça; Kullberg, José Carlos; Ramalho, José C.Zinc enrichment of edible food products, through the soil and/or foliar application of fertilizers, is a strategy that can increase the contents of some nutrients, namely Zn. In this context, a workflow for agronomic enrichment with zinc was carried out on irrigated Vitis vinifera cv. Syrah, aiming to evaluate the mobilization of photoassimilates to the winegrapes and the consequences of this for winemaking. Du...
Assessment of physicochemical parameters in two winegrapes varieties after foli...
Daccak, Diana; Lidon, Fernando C.; Coelho, Ana Rita F.; Luís, Inês Carmo; Marques, Ana Coelho; Pessoa, Cláudia Campos; Brito, Maria da GraçaOne-third of the world’s population is suffering from “hidden hunger” due to micronutrient deficiency. Zinc is acquired through diet, leading its deficiency to the development of disorders such as retarded growth, anorexia, infections, and hypogeusia. Accordingly, this study aimed to develop an agronomic workflow for Zn biofortification on two red winegrapes varieties (cv. Castelão and Syrah) and determine the ...
Mais de 30 anos de encontros de Geoquímica Ibérica: contributos do XII Congress...
Nogueira, Pedro; Moreira, Noel; Maia, Miguel; Roseiro, José; Silva, Eduardo; Kullberg, José CarlosO Congresso Ibérico de Geoquímica é neste momento um congresso de referência no âmbito da Geologia Ibérica, particularmente no domínio da Geoquímica. Os primeiros passos que levaram à realização deste encontro remontam ao longínquo ano de 1977, quando tem lugar a primeira Semana da Geoquímica, no Instituto Superior Técnico (Lisboa). Desde aí, com diversos formatos e periodicidades, o Congresso Ibérico de Geoquí...
Heritage Stone, Brecha da Arrábida, Portugal
Lopes, Luís; Kullberg, José Carlos; Prego, António; Alves, Tiago; Ruben, MartinsThe “Brecha da Arrábida” consists of an informal unit of the Upper Jurassic (Middle to Upper Oxfordian) located at the base of the “Marls, clays, limestone with black pebbles and conglomerates of Arrábida” Formation, defined at the most recent version of the Portuguese Geological Map at the 1/50.000 scale (38-B-Setúbal, IGM, 1994).The use of “Brecha da Arrábida” is closely associated with the history of the cit...
Magnesium Accumulation in Two Contrasting Varieties of Lycopersicum esculentum ...
Pessoa, Cláudia Campos; Lidon, Fernando C.; Coelho, Ana Rita F.; Marques, Ana Coelho; Daccak, Diana; Luís, Inês Carmo; Caleiro, João CravidãoAs the productivity and quality of tomato fruits are responsive to Mg applications, without surpassing the threshold of toxicity, the assessment of potential levels of Mg accumulation in tissues, as well as the interactions with Ca and physicochemical properties, prompt this study. An agronomic workflow for Mg enrichment, consisting of six foliar applications of MgSO4 with four concentrations (0%, 0.25%, 1% and...
I Mini-Olimpíadas Experimentais de Ciência.
Oliveira, Filipa; Carvalho, Maria Paula; Novais, Anabela; Mendes, Cristiana; Abrantes, I.; Gama, Ricardo; Abreu, Maria Conceição; Aibéo, AlexandreAs Olimpíadas de Ciência têm o potencial de divulgar a ciência e motivar os alunos para a mesma, estimular a construção do conhecimento científico e promover o desenvolvimento de novas metodologias em contexto escolar de 1.º Ciclo do Ensino Básico (CEB), bem como identificar indicadores relevantes na Educação em Ciências (Oliveira, & Paixão, 2018). Neste sentido, foi concebido um estudo piloto para implementar,...

Calcium biofortification of Rocha pears, tissues accumulation and physicochemic...
Pessoa, Cláudia Campos; Lidon, Fernando C.; Coelho, Ana Rita; Caleiro, João; Marques, Ana Coelho; Luís, Inês Carmo; Kullberg, José CarlosLow dietary intake of Ca in humans has been epidemiologically linked to various diseases, which can have serious health consequences over time. Accordingly, the development of an agronomic itinerary for Ca biofortification of Rocha pears and the assessment of physicochemical deviations prompted this study. Two orchards with contrasting soil and water characteristics were selected, characterized through orthopho...
“Brecha da Arrábida”: an update summary including physical tests and mechanical...
Lopes, Luís; Alves, Tiago; Kullberg, José Carlos; Martins, Ruben; Prego, AntónioThe Arrábida Breccia is a carbonate conglomeratic breccia occurring only in the chain with the same name, located in the central-occidental part of Portugal, close to the Setúbal city. It has been used from the last 2.000 years, since the Roman occupation of the Iberian Peninsula, until the exploration was completely stopped after the creation of the Natural Park of Arrábida in 1976. The uses of the Arrábida Br...
The Alpine Orogeny in the West and Southwest Iberia Margins.
Terrinha, Pedro; Ramos, Adrià; Neres, Marta; Valadares, Vasco; Duarte, João; Martinez-Loriente, Sara; Silva, Sónia; Mata, João; Kullberg, José CarlosThe Alpine orogeny is well recorded onshore and offshore by tectonic inversion of the Mesozoic rift basins. Large scale linear seamounts (more than 250 km long and with up to 5 km of uplift) involving oceanic and continental lithosphere were carried on top of thrusts, such as the Gorringe seamount and the Estremadura Spur in the SouthWest and West Iberia Margin, respectively. The SouthWest Iberia Margin also re...
