ABSTRACT
Protein content of residual meals of two sunflower cultivar during two harvest are evaluated. The relation between this component and the oil content of hull, achene and seed are showed. Negative tendency of correlation are observed between hull oil content and hull protein content, on achene oil content and achene protein content and on seed oil content and seed protein content along the harvest studied. Although the protein content for second harvest studied was lower, the apparent competitive behaviour between oil-protein was ratified.Se analizaron los contenidos proteicos de las harinas seminales residuales de extracción, correspondientes a cultivos de girasol (durante dos cosechas), con el fin de estudiar el comportamiento de esta variable en relación con los contenidos de aceite de los constituyentes de la semilla. Se realizaron correlaciones entre los contenidos proteicos de la cáscara, la pipa y la semilla, y la cantidad de aceite que éstos aportan, obteniendo tendencias de correlación negativas entre los mismos. A pesar que los contenidos proteicos obtenidos para la segunda cosecha fueron menores respecto de la primera, el comportamiento aparentemente competitivo entre aceite-proteína se ratificó con similar relevancia.
