Bases ecofisiológicas de la determinación del rendimiento y la calidad de grano en maíces pisingallo
(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 ... -
Genetic gains in grain yield and related physiological attributes in Argentine maize hybrids
(Elsevier, 2006-02)Genetic gains in grain yield and related phenotypic attributes have been extensively documented in maize (Zea mays L.), but the effect of breeding on the physiological determinants of grain yield is yet poorly understood. ... -
Photoperiod-sensitivity genes (Ppd-1) : quantifying their effect on the photoperiod response model in wheat
(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
(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
(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 ... -
Producción forrajera en pasturas base alfalfa a partir de radiación absorbida : efectos de la estructura horizontal, vertical y foliosidad del canopeo
(Facultad de Agronomía, Universidad de Buenos Aires, 2021-03)La estructura del canopeo incide sobre los componentes del modelo radiativo de producción de biomasa: la fracción de la radiación fotosintéticamente activa incidente que es absorbida (f RFAA) y la eficiencia en el uso de ... -
The physiology and genetics behind fruiting efficiency, a promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-03)The fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination (the ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
(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 ...
