Pathogenic diversity of soybean rust in Argentina, Brazil, and Paraguay
(Springer, 2013-01)Phakopsora pachyrhizi, the cause of soybean rust, is an economically important pathogen of soybean in South America. Understanding the pathogenicity of indigenous fungal populations is useful for identifying resistant plant ... -
Phenotypic plasticity for biomass partitioning in maize : genotype effects across a range of environments
(Elsevier, 2020-10)El rendimiento en grano de maíz está determinado por el genotipo (G), el ambiente (E) y los efectos de la interacción G × E que influyen en la expresión de los rasgos a lo largo del ciclo del cultivo. Líneas endocriadas e ... -
Phenylpropanoids from maize pericarp: resistance factors to kernel infection and fumonisin accumulation by Fusarium verticillioides
(Springer, 2013-01)The aim of this work was to investigate the role of pericarp phenylpropanoids as resistance factors to F. verticillioides in eleven maize genotypes. Disease severity and kernel fumonisin accumulation were measured after ... -
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ... -
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 ... -
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 ... -
Physicochemical transformations of corn-based snacks with underexploited grains addition during storage: multi-analytical assessment
(Wiley, 2022-11)Corn-based snacks were prepared with the addition of 25% of millet, sorghum, quinoa, and canary seed flours, which are scarcely used grains for human food and can grow in low-fertility soils. GuggenheimAnderson-de Boer (GAB) ... -
Plaguicidas retenidos en el suelo y perdidos por escurrimiento en dos secuencias de cultivo bajo siembra directa
(Asociación Argentina Ciencia del Suelo, 2019-12)Los plaguicidas utilizados en la agricultura, además de cumplir con su función objetivo de control, se distribuyen en el ambiente y pueden ser retenidos, degradados y/o transformados, o también transportados fuera del lugar ... -
Polimorfismos en el extremo 5’ del gen WDTC1 y su asociación con el espesor de grasa dorsal en cerdos Landrace
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2020-06)El gen WDTC1 (WD tetratricopeptido 1) tiene una función anti-adipogénica, convirtiéndose de esta manera en un gen candidato para explicar la variación fenotípica en caracteres de importancia económica de la producción ... -
Post-grazing cutting management in tall fescue affects the sward structure, forage and liveweight production
(2019-09)Tall fescue is the main perennial grass of the pastures of the temperate region of Argentina. However, after flowering in spring, tall fescue loses productivity and quality. Based on this, the objective of this work was ... -
Predicting junglerice (Echinochloa colona L.) emergence as a function of thermal time in the humid pampas of Argentina
(Taylor & Francis, 2020-06)Junglerice (Echinochloa colona) is one of the most important annual weeds affecting crops in Argentina. A predictive seedling emergence model based on thermal time was developed and validated. Monitoring of seedling emergence ... -
Projection of soil organic carbon reserves in the Argentine Rolling Pampa under different agronomic scenarios. Relationship of these reserves with some soil properties
(Bentham Open, 2015)The soil organic carbon (SOC) of the Argiudolls of the Argentine Rolling Pampa evolves rapidly. Currently, the soils richest in SOC are cultivated with intensified crop sequences (e.g. maize-double cropped wheat/soybean, MWS) ... -
Pronase hydrolysis as a pretreatment for quantifying Maillard intermediates during toasting of cornflakes
(ISEKI Food Association, 2016-04)Some of the products generated by the Maillard reaction are desired and very important for defining consumer acceptance of breakfast cereals. However, in recent years there has been an increased concern about compounds ... -
Prospects for plant productivity: from the canopy to the nucleus
(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 ... -
Quantitative trait loci for Fusarium and Gibberella ear rot resistance in Argentinian maize germplasm
(2016)Fusarium verticillioides and F. graminearum cause ear rots in maize (Zea mays L.) that reduce yield and contaminate the grain with mycotoxins produced by the fungi. To map QTLs for resistance to these ear rots, a F5 mapping ... -
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 ... -
Reducción del drenaje profundo y la lixiviación de nitrógeno en rotaciones agrícolas con cultivos de cobertura
