Preserving and hydrogel-matrixing the bioactive properties of aromatic medicina...
Parracho, Tiago; Cruz, Pedro F.; Peralta, Claúdia C.; Silva, Cândida G.; Campos, Maria Jorge; Neves, Marta; Cordeiro, Rachel; Trindade, DanielaEdible wild plants are part of the ethnobotanic heritage of a certain geographical area and are important sources of essential oils, antioxidants, minerals, and special flavours. Corema album (Portuguese crowberry), Crithmum maritimum (sea fennel), Eryngium maritimum (sea holly), Helichrysum italicum (curry plant) and Otanthus maritimus (cottonweed) wildly flourish along the sandy dunes of the coast of the Iber...
Retention of minerals, antioxidants, pigments, and glucosinolates by broccoli f...
Ribeiro, Vânia S.; Cruz, Pedro F.; Almeida, Zaida L.; Silva, Cândida G.; Silva, Maria Isabel; Silva, Inês S.; Santos, Liliana R.; Santos, Marta T.Given the poor palatability and chewability of crude green bean pods (Phaseolus vulgaris) and broccoli florets (Brassica oleracea var. italica Plenck) these vegetables are generally microwaved, steamed or water boiled. Hence, here, we evaluated the contents of minerals, antioxidants, phenolics, glucosinolates, pigments, colour, texture and flavour of water-boiling broccoli and green bean pods, with four mineral...
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...
Soil arsenic toxicity impact on the growth and C-Assimilation of Eucalyptus nitens
Ramalho, José C.; Pelica, João; Lidon, Fernando C.; Silva, Maria M. A.; Simões, Maria M.; Guerra, Mauro; Reboredo, Fernando H.The selection of adequate plants that can cope with species that can live in contaminated/ degraded and abandoned mining areas is of utmost importance, especially for environmental management and policymakers. In this framework, the use of a fast-growing forestry species, such as Eucalyptus nitens, in the recovery of arsenic (As) from artificially contaminated soils during a longterm experiment was studied. Roo...
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...
Effect of rice grain (Oryza sativa L.) enrichment with selenium on foliar leaf ...
Marques, Ana Coelho; Lidon, Fernando C.; Coelho, Ana Rita F.; Pessoa, Cláudia campos; Luís, Inês Carmo; Campos, Paula Scotti; Simões, ManuelaAn agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with sodium selenate and sodium selenite with different concentrations (25, 50, 75 and 100 g Se.ha1), was implemented in experimental fields. The selenium toxicity threshold was not exceeded, as shown by the eco-physiological data obtained through leaf gas exchanges. The highest Se enrichment in ...
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...
The tolerance of Eucalyptus globulus to soil contamination with arsenic
Reboredo, Fernando Henrique; Pelica, João; Lidon, Fernando C.; Pessoa, Maria F.; Silva, Maria Manuela; Guerra, Mauro; Leitão, Roberta; Ramalho, José C.The contamination of abandoned mining areas is a problem worldwide that needs urgent attention. Phytoremediation emerges as a successful method to extract different contaminants from the soil. In this context, Eucalyptus globulus plants growing in soils artificial contaminated with arsenic (As) were used to access its phytoremediation capabilities. The effects of As on photosynthetic performance were monitored ...
Zinc Enrichment in Two Contrasting Genotypes of Triticum aestivum L. Grains: In...
Luís, Inês Carmo; Lidon, Fernando C.; Pessoa, Cláudia Campos; Marques, Ana Coelho; Coelho, Ana Rita F.; Simões, Manuela; Patanita, Manuel; Dôres, JoséThis study aimed to assess the implications of Zn enrichment in wheat grains as a function of contrasting genotypes, edaphic conditions and foliar fertilizers. Triticum aestivum L. varieties Roxo and Paiva were grown in four production fields, and sprayed with ZnSO4 (0, 16.20 and 36.40 kg/ha) Zn-EDTA (0, 6.30 and 12.60 kg/ha) and Tecnifol Zinc (0, 3.90 and 7.80 kg/ha). The heterogeneous edaphic conditions of th...
Can foliar pulverization with CaCl2 and Ca(NO3)2 trigger Ca enrichment in Solan...
Coelho, Ana Rita F.; Lidon, Fernando C.; Pessoa, Cláudia Campos; Marques, Ana Coelho; Luís, Inês Carmo; Caleiro, João; Simões, Manuela; Kullberg, JoséThis study aimed to assess the efficiency of Ca enrichment in tubers of three genotypes of Solanum tuberosum L., through foliar spraying with CaCl2 and Ca(NO3)2 solutions. In this context, soil heterogeneity of three potato-growing fields, as well as the implications of Ca accumulation among tissues and some quality parameters were assessed. Three potato varieties (Agria, Picasso and Rossi) were grown in three ...
