Megjegyzések:	Inorganic fertilizers are routinely used in large scale crop production for the supplementation of nitrogen, phosphorus, and potassium in nutrient poor soil. To explore metabolic changes in tomato plants grown on humic sand under different nutritional conditions, matrix-assisted laser desorption ionization (MALDI) mass spectrometry was utilized for the analysis of xylem sap. Variations in the abundances of metabolites and oligosaccharides, including free N-glycans (FNGs), were determined. Statistical analysis of the sample-related peaks revealed significant differences in the abundance ratios of multiple metabolites, including oligosaccharides, between the control plants, grown with no fertilizers, and plants raised under "ideal" and "nitrogen deficient" nutritional conditions, i.e., under the three treatment types. Among the 36 spectral features tentatively identified as oligosaccharides, the potential molecular structures for 18 species were predicted based on their accurate masses and isotope distribution patterns. To find the spectral features that account for most of the differences between the spectra corresponding to the three different treatments, multivariate statistical analysis was carried out by orthogonal partial least squares-discriminant analysis (OPLS-DA). They included both FNGs and non-FNG compounds that can be considered as early indicators of nutrient deficiency. Our results reveal that the potential nutrient deficiency indicators can be expanded to other metabolites beyond FNGs. The m/z values for 20 spectral features with the highest variable influence on projection (VIP) scores were ranked in the order of their influence on the statistical model.

Cím:	Determination of field capacity in the Chibunga and Guano rivers micro-basins / Benito Mendoza, Manuel Fiallos, Sandra Iturralde, Patricio Santillán, Nelly Guananga, Jaime Bejar, Daniel A. Lowy, Imre Vágó, Zsolt Sándor

Megjegyzések:	The micro-basins of the Chibunga and Guano rivers are located within the sub-basin of the Chambo river, extending from the thaw of the Chimborazo, passing through the cities of Guano and Riobamba, and ending in the Chambo river. These rivers are considered fluvial hydrological forces and geological limits of the aquifer, located in this sub-basin. For this reason, the present investigation has as objective the study of the field capacity in the micro-basins of Chibunga and Guano rivers, for determining the maximum retention potential, that is, the saturation of water in the soil. We address the change of precipitation to runoff through the correlations between the characteristics of the soil and its vegetation. Likewise, the curve number method introduced by the United States Soil Conservation Service (USSCS) was used; this is an empirical model that relates the vegetation cover and the geological and topographic conditions of the soil. Along with the geographic information system, the model allows to represent the variation of runoff for each micro-basin, according to the different land use categories, over the time frame from 2010 to 2014. Results of this work will be useful in the quantification of the water balance, to determine the water supply and demand.
