Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil
Carrera, Constanza Soledad; Salvagiotti, Fernando; Ciampitti, Ignacio A. (Frontiers Media, 2021-08-11)The aim of this study was to explore relationships between protein, oil, and seed weight with seed nutraceutical composition, focused on total isoflavone (TI) and total tocopherol (TT) contents across genotypic and ... -
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 ... -
Ecophysiological mechanisms underlying the positive relationship between seed protein concentration and yield in soybean under field heat and drought stress
Ergo, Verónica Vanesa; Veas, Rodolfo Ezequiel; Vega, Claudia Rosa Cecilia; Lascano, Hernan Ramiro; Carrera, Constanza Soledad (Wiley, 2024-06)A positive relationship between protein concentration and yield has been documented in different combinations of genotype and environment, often under potential conditions. However, the ecophysiological bases underlying ... -
Factors Affecting Tocopherol Concentrations in Soybean Seeds
Carrera, Constanza Soledad; Seguin, Philippe (American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Floral nectaries of Heliocarpus popayanensis and Luehea divaricata (Malvaceae-Grewioideae): structure and ultrastructure
Lattar, Elsa C.; Galati, Beatriz Gloria; Carrera, Constanza Soledad; Ferrucci, María S. (2018-03)The structure and ultrastructure on floral nectaries of Heliocarpus popayanensis Kunth. and Luehea divaricata Mart (Malvaceae-Grewioideae) were investigated for the first time. The floral nectaries of the analysed species ... -
Heat and water stressed field-grown soybean : a multivariate study on the relationship between physiological-biochemical traits and yield
Ergo, Verónica Vanesa; Lascano, Hernan Ramiro; Vega, Claudia Rosa Cecilia; Parola, Rodrigo; Carrera, Constanza Soledad (Elsevier, 2018-04)Heat stress (HS) combined with water stress (WS) negatively impact soybean [Glycine max (L.) Merr.] production. The aims of this research were to quantify the combined effect of HS and WS during grain filling (GF) on grain ... -
High night temperature during maize post-flowering increases night respiration and reduces photosynthesis, growth and kernel number
Kettler, Belén Araceli; Carrera, Constanza Soledad; Nalli Sonzogni, Federico David; Trachsel, Samuel; Andrade, Fernando Hector; Neiff, Nicolás (Wiley, 2022-03-15)In the last years globally, daily night-time low temperatures have increased more than twice compared with maximum temperatures. There is little evidence about maize growth and yield responses to high night temperature ... -
Leaf Photosynthesis and Senescence in Heated and Droughted Field-grown Soybean with Contrasting Seed Protein Concentration
Ergo, Verónica Vanesa; Veas, Rodolfo Ezequiel; Vega, Claudia Rosa Cecilia; Lascano, Hernan Ramiro; Carrera, Constanza Soledad (Elsevier, 2021-06-06)Soybean plants under heat and drought generate a multiplicity of responses in photosynthesis and senescence, impairing growth, yield, and seed quality. The goal of this study was to analyze and quantify independent and ... -
Leaf structure and ultrastructure changes induced by heat stress and drought during seed filling in field-grown soybean and their relationship with grain yield
Carrera, Constanza Soledad; Solis, Stella M.; Ferricci, María S.; Vega, Claudia Rosa Cecilia; Galati, Beatriz G.; Ergo, Veronica Vanesa; Andrade, Fernando Hector; Lascano, Hernan Ramiro (Academia Brasileira de Ciências, 2021)Studies focusing on terminal drought combined with heat impacts on plants of agronomic value remain scarce, and even less under field conditions. The objective of this study was to investigate leaf structural and ultrastructural ... -
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 ... -
Soybean pod and grain isoflavones accumulation during the filling period in field conditions
Carrera, Constanza Soledad; Urretabizkaya, Nestor; Gontijo Mandarino, José Marcos; Leite, Rodrigo Santos; Szemruch, Cyntia Lorena; Rondanini, Deborah Paola (Ediciones INTA, 2021-12)The objective of this work was to determine the isoflavones accumulation in soybean pods and grains during the filling period in field conditions. Pods of the same phenological stage (marked in R5, i.e. beginning of grain ... -
Soybean seed growth dynamics exposed to heat and water stress during the filling period under field conditions
Veas, Rodolfo Ezequiel; Ergo, Verónica Vanesa; Vega, Claudia Rosa Cecilia; Lascano, Hernan Ramiro; Rondanini, Deborah Paola; Carrera, Constanza Soledad (Wiley, 2021-05-27)Soybean production can be affected by heat (HS) and water stress (WS). However, studies on effects of stresses combination under field conditions are still scarce. The objective of this study was to evaluate the impact of ... -
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 ...
