No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
Nutritional evaluation of dried tomato seeds
(Oxford Academic Press, 2003-01)Two samples of tomato seeds, a by-product of the tomato canning industry were evaluated to determine proximate analysis, amino acid content, and digestibility, TMEn, and protein efficiency ratio. Tomato seeds were also ... -
On-farm soybean genetic progress and yield stability during the early 21st century: A case study of a commercial breeding program in Argentina and Brazil
(Elsevier, 2024-03)CONTEXT: Most studies assessing the genetic progress in soybean have traditionally focused on retrospectives approaches, where commercial genotypes released over an extended period are tested in a limited number of ... -
Organic agriculture in Argentina’s Pampas. A case study on Pampa Orgánica Norte farmers
(Cambridge University Press, 2022-02)Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative ... -
Ornamentos sexuales y caracteres productivos en gallinas Campero Casilda
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste (UNNE), 2022-12)Con el objetivo de asociar el tamaño de los ornamentos sexuales con caracteres reproductivos y productivos en gallinas del cruzamiento de tres vías Campero Casilda se calcularon, en 97 aves de 30 semanas, los índices de ... -
OSTRICH-CROPGRO multi-objective optimization methodology for calibration of the growing dynamics of a second-generation transgenic soybean tolerant to high temperatures and dry growing conditions
(Elsevier, 2023-02)Current estimates show that the impact of climate change on agriculture will result in yield losses in major crops of 8–43%, mainly due to a combination of drought and heat. Second-generation transgenic crops are expected ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
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 ... -
