Changes in number and weight of wheat and triticale grains to manipulation in source-sink relationship
Ballesteros Rodríguez, Elia; Martínez Rueda, Carlos Gustavo; Morales Rosales, E. J.; Estrada Campuzano, Gaspar; Gonzalez, Fernanda Gabriela (Hindawi, 2019-01)The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and ... -

Field-grown transgenic wheat expressing the sunflower gene HaHB4 significantly outyields the wild type
Gonzalez, Fernanda Gabriela; Capella, Matías; Ribichich, Karina Fabiana; Curín, Facundo; Giacomelli, Jorge Ignacio; Ayala, Francisco; Watson, Gerónimo; Otegui, María Elena; Lía Chan, Raquel (2019-02)HaHB4 is a sunflower transcription factor belonging to the homeodomain-leucine zipper I family whose ectopic expression in Arabidopsis triggers drought tolerance. The use of PCR to clone the HaHB4 coding sequence for wheat ... -
Fruiting efficiency : an alternative trait to further rise wheat yield
Slafer, Gustavo A; Elia, Mónica; Savin, Roxana; García, Guillermo Ariel; Terrile, Ignacio Ismael; Ferrante, Ariel; Miralles, Daniel Julio; Gonzalez, Fernanda Gabriela (2015-07)Further improvements in wheat yields are critical, for which increases in grain number would be required. In the recent past, higher grain number was achieved through increased growth of the juvenile spikes before anthesis, ... -
Photoperiod-sensitivity genes (Ppd-1) : quantifying their effect on the photoperiod response model in wheat
Perez Gianmarco, Thomas; Severini, Alan David; Gonzalez, Fernanda Gabriela (Oxford University Press, 2019-10)Coupling anthesis date to the most suitable environmental conditions is critical for wheat (Triticum aestivum L.) adaptation and yield potential. Development to anthesis is controlled by temperature and photoperiod. Response ... -
Photoperiod-sensitivity genes shape floret development in wheat
Perez Gianmarco, Thomas; Slafer, Gustavo A.; Gonzalez, Fernanda Gabriela (2019-02)Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ... -
Producción de trigo: evolución, demanda y alternativas para mejorarla. Una visión ecofisiológica
Gonzalez, Fernanda Gabriela; Perez-Gianmarco, Thomas; Pretini, Nicole; Curín, Facundo (Ediciones INTA, 2018-04)La producción de trigo a nivel global es clave para alcanzar un estándar razonable de seguridad alimentaria. Mejorar los rendimientos obtenidos en un país exportador como Argentina permite aumentar los excedentes de ... -
Progreso de rendimiento en trigo argentino en los últimos 30 años bajo condiciones potenciales y limitadas por nitrógeno y/o agua
Curín, Facundo; Otegui, María Elena; Gonzalez, Fernanda Gabriela (Ediciones INTA, 2018-04)El progreso genético del rendimiento en trigo resultó de 0,8 % anual para los cultivares liberados en los últimos 30 años. Dicho progreso se mantuvo ante condiciones limitantes de nitrógeno y agua, reforzando la idea de ... -
Prospects for plant productivity: from the canopy to the nucleus
Gonzalez, Fernanda Gabriela; Manavella, Pablo A. (Oxford University Press, 2021-05)Population growth has been closely associated with agricultural production, since the first famine predicted by Malthus (1798) up to the Green Revolution of the past century. Today, we continue to face increasing demand ... -
Relación entre el coeficiente de fertilidad de la espiga de trigo y el peso de los granos
Pretini, Nicole; Terrile, Ignacio Ismael; Donaire, Guillermo Manuel; Gonzalez, Fernanda Gabriela (2018-08)El coeficiente de fertilidad de la espiga (CFE) ha sido identificado como atributo promisorio para incrementar el número de granos (Ng) y así el rendimiento de trigo. sin embargo, para que la selección por CFE resulte no ... -
