Bases ecofisiológicas de la determinación del rendimiento y la calidad de grano en maíces pisingallo
Severini, Alan David (Facultad de Agronomía, Universidad de Buenos Aires, 2011-05)El cultivo de maíz pisingallo (Zea mays L. var. everta) es una alternativa conveniente en la diversificación de la producción de granos en Argentina, sin embargo las bases ecofisiológicas de la determinación del rendimiento ... -
Eficiencia de uso del agua de cultivares de soja desarrollados para La Pampa central Argentina: efectos del mejoramiento genético y del ambiente
Avalos Brítez, S.R.; Severini, Alan David; Cirilo, Alfredo Gabriel; Otegui, María Elena (Asociación de la Cadena de la Soja Argentina, 2019-09)En los próximos años se prevé un aumento importante en la demanda mundial de alimentos como producto de un incremento de la población. Para cubrir esa demanda, la producción deberá aumentar a casi el doble (Ray et al., ... -
Kernel number and kernel weight determination in dent and popcorn maize
Severini, Alan David; Borrás, Lucas; Westgate, Mark E.; Cirilo, Alfredo Gabriel (Elsevier, 2011-02)Yield formation in maize (Zea mays L.) dent hybrids has been directly linked to the rate of plant biomass accumulation and partitioning of assimilates to the developing grain. Maize popcorn genotypes have been studied less ... -
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 ... -
Predicting soybean development with a simple photothermal dynamic algorithm
Severini, Alan David; Álvarez Prado, S.; Otegui, María Elena; Vega, Claudia Rosa Cecilia; Zuil, Sebastian; Kavanová, M.; Ceretta, S.; Acreche, Martin Moises; Scholz Drodowski, R.F.; Serrago, R.A.; Miralles, D.J. (Asociación de la Cadena de la Soja Argentina, 2019-09)Predicting the occurrence of the critical period for soybean’s yield determination is important for farmers to decide on variety and sowing date with the objective to expose this period (during which yield is mainly ... -
Root depth: a trait to increase water use and yield of wheat
Severini, Alan David (Australian National University, 2015-11)Crops with deeper roots could potentially capture more soil resources and as a consequence yield more. However, as sampling roots by soil coring is challenging, there are few examples of genetic diversity determined under ... -
Root phenotypes at maturity in diverse wheat and triticale genotypes grown in three field experiments: Relationships to shoot selection, biomass, grain yield, flowering time, and environment
Severini, Alan David; Wasson, Anton P.; Evans, John R.; Richards, Richard A.; Watt, Michelle (Elsevier, 2020-09)Modelling and limited data suggest that crops with deeper and longer roots capture more soil resources and yield more when water is available deeper in soil profiles. Interest has grown in the development of new cultivars ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
Curin, Facundo; Severini, Alan David; Gonzalez, Fernanda Gabriela; Otegui, María Elena (Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
Perez Gianmarco, Thomas; Severini, Alan David; Gonzalez, Fernanda Gabriela (Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ...
