Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
Carrera, Constanza Soledad; Dardanelli, Julio Luis (Blackwell, 2016-12)Isoflavones have been shown to have health‐promoting activities in humans and are particularly abundant in soya bean. This study was conducted to determine how water deficit during seed fill affects the already known ... -
Chemical compounds related to nutraceutical and industrial qualities of non‐transgenic soybean genotypes
Carrera, Constanza Soledad; Dardanelli, Julio Luis; Soldini, Diego Omar (Wiley; Society of Chemical Industry, 2014-05)BACKGROUND: Information about the chemical profile of soybean seed is valuable for breeding programs aimed at obtaining value‐added products to meet the demands of niche markets. The objective of this study was to determine ... -
Environmental effects on seed yield determination of irrigated peanut crops: links with radiation use efficiency and crop growth rate
Haro Juarez, Ricardo Javier; Otegui, María Elena; Collino, Daniel; Dardanelli, Julio Luis (Elsevier, 2007-08-12)In Argentina, delayed sowing causes a decrease in seed yield and in radiation use efficiency (RUE) of peanut crops (Arachis hypogaea L.), but it is not known if RUE reduction is mainly due to reduced temperature during ... -
Environmental Variation and Correlation of Seed Components in Nontransgenic Soybeans: Protein, Oil, Unsaturated Fatty Acids, Tocopherols, and Isoflavones
Carrera, Constanza Soledad; Martinez, Maria Jose; Dardanelli, Julio Luis; Balzarini, Mónica (Crop Science Society of America, 2011-03-01)The environment has a significant influence on the expression of traits contributing to soybean nutritional and/or industrial value. The aim of this study was to explore and describe the variability of nontransgenic soybean ... -
Oil quality and sugar content of peanuts (Arachis hypogaea) grown in Argentina : their relationship with climatic variables and seed yield
Casini, Cristiano; Dardanelli, Julio Luis; Martinez, Maria Jose; Nassetta, Mirtha; Borgogno, Carmen S.; Balzarini, Mónica Graciela (2003-09)The ratio of oleic to linoleic acids (O/L) and the tocopherol content are important features in determining peanut (Arachis hypogaea) seed shelf life. Soluble carbohydrates are known to be important precursors in roasted ... -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
Carrera, Constanza Soledad; Rosas, María Belén; Gontijo Mandarino, José M.; Leite, Rodrigo Santos; Raspa, Francisco Antonio; Fava, Fernando Daniel; Dardanelli, Julio Luis; Andrade, Fernando Hector (Wiley, 2022-01-08)BACKGROUND: Little is known about soybean grain chemical composition response to defoliation. The objectives of our study were: (i) to quantify the impact of different levels and timing of defoliation during the filling ... -
Regional model for nitrogen fertilization of site-specific rainfed corn in haplustolls of the central Pampas, Argentina
Gregoret, María Celeste; Diaz Zorita, Martin; Dardanelli, Julio Luis; Bongiovanni, Rodolfo (Springer, 2011-12)In semi-arid regions, soil water and nitrogen (N) are generally limiting factors for corn (Zea mays L.) production; hence, implementation of appropriate N fertilization strategies is needed. The use of precision agriculture ... -
Seed yield determination of peanut crops under water deficit: Soil strength effects on pod set, the source–sink ratio and radiation use efficiency
Haro Juarez, Ricardo Javier; Dardanelli, Julio Luis; Otegui, María Elena; Collino, Daniel (Elsevier, 2008-06-10)Peanut (Arachis hypogaea L.) production in Argentina is affected by frequent and unpredictable periods of water deficit that usually overlap the critical period for pod set of early sown crops. An indirect effect of water ... -
Variabilidad del rendimiento del cultivo de soja Glycine max (L) Merr., en sistemas de siembra directa en el sur de Santa Fe
Bacigaluppo, Silvina (Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2009)La soja, Glycine max (L.) Merr., es el cultivo de mayor importancia económica en Argentina. El sur de la provincia de Santa Fe (32º 25´ - 33º 48´ S; 60º 20´ - 62º 00´ O) pertenece al área sojera núcleo, donde el 80% de la ... -
Water Deficit Effect on the Relationship between Temperature during the Seed Fill Period and Soybean Seed Oil and Protein Concentrations
Carrera, Constanza Soledad; Martinez, Maria Jose; Dardanelli, Julio Luis; Balzarini, Mónica (Crop Science Society of America, 2009-05-01)Since most soybean [Glycine max (L.) Merr.] seed is processed into meal and oil, there is a growing concern about environmental effects on soybean seed composition. The aim of this work was to investigate how water deficit ... -
Water Deficit Modulates the Relationship between Temperature and Unsaturated Fatty Acid Profile in Soybean Seed Oil
Carrera, Constanza Soledad; Dardanelli, Julio Luis (Crop Science Society of America, 2017-08-23)Soybean [Glycine max (L.) Merr.], a major source of vegetable oil worldwide, contains unsaturated fatty acids (UFA) beneficial for human health, leading to the use of soybean oil in nutraceuticals. The objective of this ... -
Water table contribution to alfalfa water use in different environments of the Argentine Pampas
Dardanelli, Julio Luis; Collino, Daniel (Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2002)In the Argentine Pampas, although the water table is considered an important source of water supply for the alfalfa crop, it has not been previously quantified.The goal of this study was to estimate ...
