Genomic relationships between hexaploid Helianthus resinosus and diploid Helianthus annuus (Asteraceae)
(Springer, 2014-05)Genus Helianthus comprises diploid and polyploid species. An autoallopolyploid origin has been proposed for hexaploid species but the genomic relationships remain unclear. Mitotic and meiotic studies in annual Helianthus ... -
Germination and Vigor of Maize Seeds: Pilot-Scale Comparison of Low-Oxygen and Traditional Storage Methods
(Multidisciplinary Digital Publishing Institute, MDPI, 2024-08)Seed quality declines during storage depending on relative humidity, temperature, and oxygen concentration. Low-oxygen atmospheres significantly enhanced the germination and vigor of seeds during storage in laboratory-scale ... -
Glyphosate and aminomethylphosphonic acid (AMPA) are commonly found in urban streams and wetlands of Melbourne, Australia
(Elsevier, 2020-01)Glyphosate is the most widely-used pesticide for weed control in agriculture and in urban and residential areas. This is the first study to quantify glyphosate and AMPA levels in surface water in Australia from different ... -
Glyphosate and AMPA concentrations in the respirable dust emitted experimentally by soil aggregates, shortly after herbicide application
(Elsevier, 2020-06-15)The objective of this study was to analyze glyphosate- and aminomethylphosphonic acid (AMPA) concentrations in the respirable dust (RD) emitted by different soil aggregates, shortly after herbicide application in a field ... -
Glyphosate and AMPA concentrations in wind‐blown material under field conditions
(Wiley Online Library, 2018-03-01)Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased ... -
Glyphosate Biodegradation Potential in Soil Based on Glycine Oxidase Gene (thiO) from Bradyrhizobium
(Springer Nature, 2021-04-02)Despite the intensive use of glyphosate (GP) and its ubiquitous presence in the environment, studies addressing the presence of microbial genes involved in glyphosate degradation in natural conditions are scarce. Based on ... -
Glyphosate runoff and its occurrence in rainwater and subsurface soil in the nearby area of agricultural fields in Argentina
(Elsevier, 2019-06)Glyphosate-based products are among the most important herbicides applied to enhance the production of food commodities, leading to the worldwide spread of this herbicide. The main goal of this work was to evaluate the ... -
Glyphosate sorption to soils of Argentina. Estimation of affinity coefficient by pedotransfer function
(Elsevier, 2018)Argentine agricultural production is fundamentally based on technological package that combines direct seeding and glyphosate with transgenic crops (soybean, maize and cotton), which makes glyphosate the most widely ... -
Glyphosate, AMPA, and metsulfuron-methyl retention in the main horizons of a typic argiudoll
(Taylor and Francis, 2022-05-03)Retention is one of the processes controlling the behavior and fate of pesticides in soil. The objective of this work was to evaluate the adsorption and desorption of glyphosate, AMPA, and metsulfuron-methyl in the main ... -
Gross nitrogen mineralization and immobilization in temperate maize-soybean intercrops
(Springer, 2015-06)Background and aims: Reliance on nitrogen (N) fertilizers to maintain crop productivity requires a thorough understanding of the transformation of this nutrient within the soil-plant system. Organic matter input from a ... -
Growth of the wild potato Solanum commersonii (Solanaceae) among grass tussocks under different defoliation intensities = Crecimiento de la papa silvestre Solanum commersonii (Solanaceae) entre matas de gramíneas bajo diferentes intensidades de defoliación
(Asociación Argentina de Ecología, 2018)Solanum commersonii is a wild potato, valuable as a socioeconomic resource for a breeding program of feeding crops. In grasslands, this species grows associated to Paspalum quadrifarium, a forage grass managed under ... -
Growth, carcass and meat quality traits in beef from Angus, Hereford and cross-breed grazing steers, and their association with SNPs in genes related to fat deposition metabolism
(2016)Grazing steers from Angus and Hereford breeds, their cross-breeds and a three-way cross-breed (Limousin × Angus–Hereford) were measured for growth, carcass andmeat quality traits. Breed effectswere studied, and the association ... -
Grupos funcionales de plantas, producción de forraje y eficiencia de uso de radiación de pastizales naturales en condiciones potenciales y limitadas de agua y nitrógeno
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Con el objetivo de analizar el efecto de la disponibilidad hídrica y nitrogenada sobre el crecimiento primavero estival de forraje, se condujo un experimento en un pastizal natural de la Pampa Deprimida (Argentina) con ... -
Guanaco abundance and monitoring in Southern Patagonia: distance sampling reveals substantially greater numbers than previously reported
(Springer, 2015-12)Background: Guanacos (Lama guanicoe) are thought to have declined in Patagonia mainly as a result of hunting and sheep ranching. Currently accepted estimates of total population size are extrapolated from densities obtained ... -
Habitat suitability models for the sand lizard Liolaemus wiegmannii based on landscape characteristics in temperate coastal dunes in Argentina
(Wiley, 2016-09)The knowledge of environmental variables associated with the species occurrence allows the recognition of sites which fulfil ecological requirements eventually used for conservation of species. The coastal dunes of Argentina ... -
