A time-window within the grain filling period accounted for early leaf senescence in maize under sink limitation
(Elsevier, 2024-01)In annual crops such as maize, assimilates demand exerted by grains converges with increasing leaf senescence. As sink demand changes as grains growth, leaf senescence could also be affected during the grain filling period. ... -
Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
(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 ... -
La fotooxidación en la semilla de sauce y sus consecuencias en la imbibición y formación de la plántula
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2012-06)A diferencia de lo que ocurre en una semilla ortodoxa típica, los tejidos embrionarios de las semillas de sauce (Salix nigra L.) presentan cloroplastos que no desdiferencian durante la maduración del secado, por lo que ... -
Influencia de la temperatura en llenado de grano como factor determinante de la presencia de granos verdes en soja
(Facultad de Agronomía, Universidad de Buenos Aires, 2013)Una de las características que define la calidad de los granos de soja es la presencia de granos verdes (GV). Estos exhiben una coloración verdosa, total o parcial, debida a la presencia de pigmentos clorofílicos no ... -
Leaf Photosynthesis and Senescence in Heated and Droughted Field-grown Soybean with Contrasting Seed Protein Concentration
(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 ... -
A new sunflower high oleic mutation confers stable oil grain fatty acid composition across environments
(2016)The oil industry demands sunflower oils with high oleic acid content. New varieties producing high oleicoils independently of the growing environment are needed as growers could receive an extra prime foroffering them. Oil ... -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
(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 nitrogen sources and demand during the seed-filling period
(American Society of Agronomy, 2019-05)Soybean [Glycine max (L.) Merr.] seed N demand not met by biological N fixation is fulfilled by N remobilization from vegetative plant organs and N uptake from soil sources during the seed-filling period (SFP), herein ... -
Soybean pod and grain isoflavones accumulation during the filling period in field conditions
(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 ... -
Temperature influence during seed filling on tocopherol concentration in a traditional sunflower hybrid
(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 ...
