  2. Tackling the cell wall of the grape berry

    Goulão, L.F.; Fernandes, J.C.; Lopes, P.; Amâncio, Sara
    The cell wall (CW) is the dynamic border of plant cells. In grape berries, the CW decisively accounts for the difference between the pulp and skin cells, with direct consequences on the grape characteristics, wine quality and wine-making methods. The softening of mature berries results from the depolymerisation and solubilisation of CW polymers. Modifications of grape pulp and skin CW provide the flexibility for cell expansion during fruit growth and to modulate the final texture. Wine making and berry processing methods are directly related with the absence, in white wines, or the presence, in red wines, of skin CW in the fermenting must. Anthocyanin extraction depends...

  12. Nutrient removal effectiveness by riparian buffer zones in rural temperate watersheds: the impact of no-till crop practices

    Aguiar Jr., T.R.; Rasera, K.; Parron, L.M.; Brito, A.G.; Ferreira, M.T.
    Riparian buffer zones have the potential to capture chemical contaminants and to mitigate detrimentalside-effects in aquatic ecosystems derived from excess fertilizers used in agro-food production. No-tillfarming systems are well known agricultural practices and are widely used in temperate areas. In thatregard, different settings and widths of riparian buffer zones (12, 24, 36, 48 and 60 m) with woody veg-etation, shrubs or grasses were assessed. The methodology was comprised of the evaluation of a largenumber of experimental sites and the sampling was conducted after the first rain period and respectivefertilizer applications. The results point to the fact that effectiveness is largely...

  14. Concentrations of available heavy metals in Mediterranean agricultural soils and their relation with some soil selected properties: a case study in typical mediterranean soils

    Nunes, José Rato; Ramos-Miras, José; Lopez-Piñeiro, António; Loures, Luís; Gil, Carlos; Coelho, José; Loures, Ana
    The characterization of the content of trace metals in soils is an instrument in many programs of environmental protection, including the establishment of regional-level standards to detect sites affected by contamination. The objectives of the present study were to study the available levels of Cd, Cr, Cu, Ni, Pb, and Zn in surface horizons of agricultural soils in a typical European Mediterranean region, to establish the geochemical baseline concentration (GBC), background level (BL), and reference value (RV) of each of these available metals, and to investigate their possible correlations with soil properties. To establish the GBC and RV values, we used the “standard threshold method”. Topsoil samples...

  15. Landscape valuation of environmental amenities throughout the application of direct and indirect methods

    Loures, Luís; Loures, Ana; Nunes, José; Panagopoulos, Thomas
    Landscape design, construction and management should no longer be the result of superficial approaches based exclusively on designers’ and planners’ ideas. This research starts with the assumption that the aesthetic component constitutes an essential attribute for better understanding and evaluating landscapes. This study analyzes the aesthetic quality and economic valuation of the Lower Guadiana river landscape, through the application of direct and indirect landscape evaluation methods. In order to gauge not only experts’ opinion, it is supported by the application of public participation techniques about the opinion and perceptions of the site visitors/users. The present research considered the analysis of six landscape subunits regarding landscape quality, fragility and...
