Topsoil hardening: effects on soybean root architecture and water extraction patterns
(Springer, 2020-09-01)Topsoil hardening is one of the major causes of poor root growth although its effects on subsoil roots are still not well-known. Our aim was to examine the effects of topsoil hardening on the growth and functioning of ... -
Comparación de indicadores de la desertificación en la Región Pampeana y en la frontera de expansión agropecuaria en la República Argentina = Desertification indicators comparison in Pampean Region and agricultural expansion frontier in the Argentine Republic
(Facultad de Agronomía, Universidad Nacional de La Plata, 2023-11-01)El proceso de desertificación se está generalizando en la Argentina. En la Región Pampeana y Extra Pampeana, la generalización del monocultivo de soja y el manejo no sustentable han aumentado el proceso de desertificación. ... -
Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat
(Wiley, 2024-01-16)In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the ... -
Population genetic characteristics and mating type frequency of Venturia effusa from Pecan in South America
(American Phytopathological Society, 2022-09-22)Scab, caused by the plant-pathogenic fungus Venturia effusa, is a major disease of pecan in South America, resulting in loss of quantity and quality of nut yield. Characteristics of the populations of V. effusa in South ... -
Assessing Payne score accuracy through a bread wheat multi-genotype and multi-environment set from CIMMYT
(Elsevier, 2024-01-01)The Payne score is a prevalent strategy for assessing wheat quality by considering the distinct contributions of specific high-molecular-weight glutenin subunits. Despite its extensive use, the limited germplasm used in ... -
