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...
Biofortificação Agronómica de Pera Rocha (Pyrus communis) em Cálcio e Implicaçõ...
Pessoa, Cláudia CamposO cálcio, para além de desempenhar funções estruturais, actua ainda como mensageiro secundário no organismo humano. O défice deste elemento mineral no organismo humano, pode promover deformações e diminuição da densidade da massa óssea, afetando o crescimento e a capacidade de locomoção, ou promover a ocorrência de fraturas. Contudo, equacionando-se como medida preventiva para a saúde o enriquecimento deste ele...
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 ...
Elemental composition and implications on brown rice flour biofortified with Se...
Marques, Ana Coelho; Lidon, Fernando C.; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Daccak, Diana; Luís, Inês Carmo; Simões, ManuelaRice (Oryza sativa L.) is one of the most economically and socially important cereals in the world. Several strategies such as biofortification have been developed in a way eco-friendly and sustainable to enhance crop productivity. This study implemented an agronomic itinerary in Ariete and Ceres rice varieties in experimental fields using the foliar application of selenium (Se) to increase rice nutritional val...
Foliar Spraying of Solanum tuberosum L. with CaCl2 and Ca(NO3)2: Interactions w...
Coelho, Ana Rita F.; Ramalho, José C.; Lidon, Fernando Cebola; Marques, Ana Coelho; Daccak, Diana; Pessoa, Cláudia Campos; Luís, Inês CarmoCalcium is essential for plants, yet as its mobility is limited, the understanding of the rate of Ca2+ accumulation and deposition in tissues of tubers, as well as the interactions with other critical nutrients prompted this study. To assess the interactions and differential accumulation of micro and macronutrients in the tissues of tubers, Solanum tuberosum L. varieties Agria and Rossi were cultivated and, aft...
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...
Mineral Monitorization in Different Tissues of Solanum tuberosum L. during Calc...
Coelho, Ana Rita F.; Lidon, Fernando C.; Pessoa, Cláudia Campos; Daccak, Diana; Luís, Inês Carmo; Marques, Ana Coelho; Ramalho, José C.Calcium is one of the 16 essential elements for plants, being required as Ca2+ and being involved in several fundamental processes (namely, in the stability and integrity of the cell wall, the development of plant tissue, cell division, and in stress responses). Moreover, Ca plays an important role in potato production. In this context, this study aimed to monitor the culture development (in situ and using an u...
Zinc Biofortification in Vitis vinifera: Implications for Quality and Wine Prod...
Daccak, Diana; Lidon, Fernando C.; Luís, Inês Carmo; Marques, Ana Coelho; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Caleiro, João; Ramalho, José C.Nowadays, there is a growing concern about micronutrient deficits in food products, with agronomic biofortification being considered a mitigation strategy. In this context, as Zn is essential for growth and maintenance of human health, a workflow for the biofortification of grapes from the Vitis vinifera variety Fernão Pires, which contains this nutrient, was carried out considering the soil properties of the v...
Enrichment of Grapes with Zinc-Efficiency of Foliar Fertilization with ZnSO4 an...
Daccak, Diana; Lidon, Fernando C.; Pessoa, Cláudia Campos; Luís, Inês Carmo; Coelho, Ana Rita F.; Marques, Ana Coelho; Ramalho, José C.Grapes and wine are widely consumed in the world, yet their mineral content can be influenced by many factors such as the mineral composition of soils, viticulture practices and environmental conditions. In this context, considering the importance of Zn in the human physiology, the enrichment of Moscatel and Castelão grapes (white and red variety, respectively) with this nutrient prompted this study; further as...
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...
