    • Assessment of nitrogen diagnosis methods in sunflower 

      Tovar Hernandez, Sergio; Diovisalvi, Natalia; Carciochi, Walter Daniel; Izquierdo, Natalia; Sainz Rozas, Hernan Rene; García, Fernando; Reussi Calvo, Nahuel Ignacio (American Society of Agronomy; Estados Unidos, 2021-04-20)
      Nitrogen deficiency can severely limit sunflower (Helianthus annuus L.) grain yield and quality. Our objective was to evaluate N diagnosis methods based on: (a) pre-plant soil nitrate-nitrogen (NO3––N) test (PPSNT) and ...

    • Development of the enhanced halsey model to predict equilibrium moisture content (EMC) of sunflower seeds with different oil contents 

      Maciel, Gisele; De La Torre, Diego; Cendoya, Maria Gabriela; Izquierdo, Natalia; Bartosik, Ricardo Enrique (American Society of Agricultural and Biological Engineers, 2018-05)
      Using the right equilibrium moisture content (EMC) relationship is critical for implementing successful aeration strategies and for determining the safe storage moisture content of grains and oilseeds. The oil content of ...

    • Methods to determine nitrogen in sunflower grains 

      Diovisalvi, Natalia; Izquierdo, Natalia; Echeverria, Hernan Eduardo; Garcia, Fernando; Reussi Calvo, Nahuel Ignacio (Asociación Argentina de la Ciencia del Suelo, 2021-12)
      In sunflower, grain oil concentration (OG) determines oil industrial yield and protein concentration (PG) determines the protein of by-products as pellets and meals (PM). There are various methodologies to quantify total ...

    • Temperature effect on triacylglycerol species in seed oil from high stearic sunflower lines with different genetic backgrounds. 

      Izquierdo, Natalia Gabriela; Martínez-Force, Enrique; Garces, Rafael; Aguirrezabal, Luis Adolfo Nazareno; Zambelli, Andrés; Reid, Roberto (John Wiley & Sons, 2016-10)
      BACKGROUND: This study characterized the influence of temperature during grain filling on the saturated fatty acid distribution in triacylglycerol molecules from high stearic sunflower lines with different genetic backgrounds. ...

    • Temperature influence during seed filling on tocopherol concentration in a traditional sunflower hybrid 

      Izquierdo, Natalia; Mascioli, Sebastian Horacio; Aguirrezabal, Luis; Nolasco, Susana María (Instituto de la Grasa, CSIC, 2007)
      Se investigó el efecto de la temperatura durante períodos cortos en el llenado de las semillas sobre la concentración de tocoferoles y la relación tocoferoles/ácido linoleico en un híbrido tradicional de girasol. Se realizó ...
