An architectural analysis of the elongation of field-grown sunflower root systems. Elements for modelling the effects of temperature and intercepted radiation
Aguirrezabal, Luis; Tardieu, F. (Society for Experimental Biology, 1996-03)The effects of photosynthetic photon flux density (PPFD) and soil temperature on root system elongation rate have been analysed by using an architectural framework. Root elongation rate was analysed by considering three ... -
Assessing the mechanisms underlying sunflower grain weight and oil content responses to temperature during grain filling
Angeloni, Patricia; Aguirrezabal, Luis; Echarte, María Mercedes (Elsevier, 2021-03)Temperature and solar radiation during grain filling are the main drivers of grain weight and composition in several crops. While significant progress has been done on the effect of solar radiation intercepted by the plants ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
Pardo, E.M.; Vellicce, Gabriel Ricardo; Aguirrezabal, Luis Adolfo Nazareno; Pereyra Irujo, Gustavo Adrian; Rocha, Carla Maria Lourdes; García, M.G.; Prieto Angueira, Salvador; Welin, Björn; Sanchez, J.; Ledesma, Fernando; Castagnaro, Atilio Pedro (Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -
Genetic variability for leaf growth rate and duration under water deficit in sunflower: analysis of responses at cell, organ, and plant level
Pereyra Irujo, Gustavo Adrian; Velazquez, Luciano; Lechner, Leandra; Aguirrezabal, Luis (Oxford Academic Press, 2008-05)Plants under water deficit reduce leaf growth, thereby reducing transpiration rate at the expense of reduced photosynthesis. The objective of this work was to analyse the response of leaf growth to water deficit in several ... -
Rewatering Plants after a Long Water-deficit Treatment Reveals that Leaf Epidermal Cells Retain their Ability to Expand after the Leaf has Apparently Reached its Final Size
Lechner, Leandra; Pereyra Irujo, Gustavo Adrian; Granier, Christine; Aguirrezabal, Luis (Oxford Academic Press, 2008-05)Background and Aims: Leaves expand during a given period of time until they reach their final size and form, which is called determinate growth. Duration of leaf expansion is stable when expressed in thermal-time and in ... -
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 ...
