Use of easy measurable phenotypic traits as a complementary approach to evaluate the population structure and diversity in a high heterozygous panel of tetraploid clones and cultivars
(Springer Nature, 2018-01-16)Background: Diversity in crops is fundamental for plant breeding efforts. An accurate assessment of genetic diversity, using molecular markers, such as single nucleotide polymorphism (SNP), must be able to reveal the ... -
Flower structure and developmental stages of the capitulum of Smallanthus sonchifolius (Asteraceae): reproductive implications.
(Springer Verlag, 2017-03)Yacon (Smallanthus sonchifolius, Asteraceae) is an ancient andean crop that has numerous dietary and medicinal properties. Morphological and anatomical features and developmental changes of the capitulum were studied. A ... -
Caracterización de compuestos antioxidantes presentes en apio según el estadio de madurez
(Asociación Argentina de Horticultura, 2012-12)El apio es apreciado por su aporte nutricional a la dieta. La “madurez comercial” es definida por el tamaño de la planta, sin embargo, el contenido en antioxidantes tiene efecto sobre la calidad nutricional y debería ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
(Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -
Indigenous mycorrhizal fungi from Argentina increase Zn nutrition of maize modulated by Zn fertilization
(Soil Science Society of Pakistan, 2014-06)The effect of nitrogen (N), phosphorous (P), sulfur (S) and zinc (Zn) fertilization on arbuscular mycorrhizal colonization (AMC), nutrition and growth of maize under contrasting tillage management was assessed in a field ... -
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ... -
Use of geophysical survey as a predictor of the edaphic properties variability in soils used for livestock production
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), España, 2015)The spatial variability in soils used for livestock production (i.e. Natraquoll and Natraqualf) at farm and paddock scale is usually very high. Understanding this spatial variation within a field is the first step for ... -
Changes in soil characteristics after six seasons of cereal–legume intercropping in the Southern Pampa
(Elsevier, 2015-04)The Argentine Pampa is one of the most productive agricultural regions in the world, but sole crop management practices have led to soil degradation and losses of soil organic matter. The objective of this study was to ... -
Slaughter weight, sex and age effects on beef shear force and tenderness
(Elsevier, 2014-05)In Argentina, beef cattle prices decrease as slaughter weight increases regardless of animal age or carcass maturity, and this decrease is significantly greater in heifers (15%) than in steers (5%). The objectives of the ... -
The first caprine rotavirus detected in Argentina displays genomic features resembling virus strains infecting members of the Bovidae and Camelidae
(Elsevier, 2014-05-25)Rotavirus group A (RVA) is a major cause of diarrhea in humans and young animals including small ruminants. The purpose of this study was to identify RVA in dairy goat kids, and to characterize the complete genomic ... -
Neosporosis epidémica y endémica: descripción de dos eventos en bovinos para cría = Endemic and epidemic bovine neosporosis: description of two events in beef cattle
(Elsevier, 2014-12)El objetivo de este trabajo es describir dos eventos producidos en la provincia de Buenos Aires en los cuales Neospora caninum estuvo asociado a la ocurrencia de abortos en bovinos de cría para carne. En uno de ellos se ... -
Quality assessment of irrigation water under a combination of rain and irrigation
(Elsevier, 2015-09)Supplementary irrigation is one of the proposed management practices to increase the area under grain production mainly in the Humid Pampas (HP). The most common source of irrigation water in the HP comes from groundwater ... -
Analysis of storage conditions of a wheat silo-bag for different weather conditions by computer simulation
(Elsevier, 2013-12)A validated mathematical model was used to analyse grain storage condition and determine the change in concentration of CO2 in a silo-bag holding wheat from summer to winter for a typical productive region with sub-tropical ... -
Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
(Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -
Azospirillum inoculation effects on growth, product quality and storage life of lettuce plants grown under salt stress
(Elsevier, 2015-11-12)Recent results have shown that Azospirillum-inoculated lettuce seeds yield a higher number of transplanted plants with superior traits than non-inoculated controls grown with and without saline stress. However, little ... -
Combined epidermal growth factor and hyaluronic acid supplementation of in vitro maturation medium and its impact on bovine oocyte proteome and competence
(Elsevier, 2015-03-15)The conditions for in vitro oocyte maturation impact on cytoplasmic and nuclear processes in the oocyte. These events are differentially influenced by the nature of the maturation inducer and the presence of intact cumulus ... -
Linoleic acid stimulates neutral lipid accumulation in lipid droplets of maturing bovine oocytes
