Relación de conversión de alimento en cinco híbridos experimentales de pollos camperos = Feed conversion ratio in fi ve experimental hybrids of free range chickens
(Facultad de Ciencias Veterinarias de Esperanza, Universidad Nacional del Litoral, 2014)La evaluación del crecimiento dimensional de cinco híbridos experimentales de pollo campero que difi eren en su genotipo materno permitió constatar la equivalencia de las poblaciones utilizadas como madre como potenciales ... -
Field-grown transgenic wheat expressing the sunflower gene HaHB4 significantly outyields the wild type
(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 ... -
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 ... -
Climate impacts on crop yields in Central Argentina. Adaptation strategies
(2018-02)The Pampas is among the major agricultural regions in the world; a large proportion of Argentina crop production is originated in this region. The exportation of grain and oil crop represents more than 40% of the total ... -
Comparación de técnicas de análisis multivariado mediante simulación para caracterización de recursos fitogenéticos en función de caracteres susceptibles a interacción genotipo-ambiente
(2018-08)Los Recursos Fitogenéticos se conservan ex situ en bancos de germoplasma. Para que los mismos sean utilizados por los mejoradores deben ser caracterizados y evaluados. En el banco de Germoplasma del INTA Pergamino se realiza ... -
Maize Nitrogen Use Efficiency: QTL Mapping in a U.S. Dent x Argentine-Caribbean Flint RILs population
(2018-04)This study was aimed to identify quantitative trait loci (QTL) for nitrogen use efficiency (NUE) and related traits in a maize population derived from a cross between two lines with different genetic background (B100 and ... -
Rapid autographic method for detection of enzymatic browning inhibitors based on enzyme immobilization
(2018-07)This work describes a TLC-coupled bioautographic assay suitable for the separation and detection of apple polyphenol oxidase (PPO) inhibitors from natural extracts. PPO was immobilised in agar containing L-DOPA as substrate ... -
Assessing changes in enriched maize flour formulations after extrusionby means of FTIR, XRD, and chemometric analysis
(2018-10)Spectral analysis employing multivariate techniques was employed to differentiate plain maize flours from formulations containing maize with added milled chia or quinoa seeds for producing cereal breakfast extrudates. The ... -
Environmental control of malting barley response to nitrogen in the Pampas, Argentina
(2018-04)Twenty five single-year field experiments were established in order to assess the effects of nitrogen fertilization on grain yield, size, and protein concentration, and to explain its response to fertilization with soil, ... -
Complementary irrigation in a maize silage double crop using the BAHICU software: a case study in Northern Buenos Aires, Argentina
(2018-04)The north of Buenos Aires province, in the Argentine Humid Pampa, is predominantly an agricultural region, where crops are grown mainly under rain fed conditions. However, in recent decades, complementary irrigation has ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
(2018-01)Fine tuning wheat phenology is of paramount importance for adaptation. A better understanding of how genetic constitution modulates the developmental responses during pre-anthesis phases would help to maintain or even ... -
Physical and mechanical properties of maize extrudates as affected by the addition of chia and quinoa seeds and antioxidants
(2015-12)The physical and mechanical properties of maize extrudates have been analyzed in relation to the addition of quinoa flour and two novel ingredients, chia and powder extract of purple corn with antioxidant properties. Maize ... -
Modeling economic-environmental decision making for agricultural land use in Argentinean Pampas
(2016-03)This research evaluates the economic and environmental impacts of land allocation to crops and extensive livestock production in the Argentine Pampas using compromise programming. Two economic indicators (gross margin, ... -
Environment, management, and genetic contributions to maize kernel hardness and grain yield
(2017-09)Dry milling performance of maize (Zea mays L.) is directly related to kernel hardness. This study assessed the contribution of maize hybrid and crop growing condition on kernel hardness and grain yield. Three hybrids that ... -
Changes of starch composition by postflowering environmental conditions in kernels of maize hybrids with different endosperm hardness
(2017-05)Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ... -
Comercialización de soja en la últimas dos décadas : mercado disponible vs. mercado de futuros
(2015-12)El agente decisor sobre la producción agropecuaria debe identificar los momentos de precios elevados a fin de obtener un buen precio de venta de su producción. Sin embargo, el agente tomador de decisión posee limitaciones ... -
Efectos de diferentes estrategias de fertilización sobre los rendimientos, el balance de nutrientes y su disponibilidad en los suelos en el largo plazo
(IPNI, 2015-09)A nivel productivo, las deficiencias de nitrógeno (N), fósforo (P) y azufre (S) no ocurren de manera aislada sino que se combinan de diversas maneras, por lo que es necesario evaluar integralmente la respuesta a la ...
