Actividad de cletodim y haloxifop R-metil en el suelo y su efecto fitotóxico en el cultivo de maíz (Zea mays)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2017-12-27)Los herbicidas haloxifop R-metil y cletodim pueden persistir activos en el suelo causando efectos fitotóxicos a cultivos de gramíneas cuando son aplicados próximos a la siembra. En este trabajo se realizaron experimentos ... -
Allele mining in the Argentine public maize inbred line collection of two paralogous genes encoding NAC domains
(Springer Nature, 2017-01)NAC proteins are plant transcription factors involved in biotic and abiotic stress responses, with conserved sub-domain motifs. To our knowledge, no diversity studies have been carried out at the nucleotide level of candidate ... -
Amino acid composition of soybean seeds as affected by climatic variables
(Empresa Brasileira de Pesquisa Agropecuária (Embrapa), 2011-09-12)The objective of this work was to perform a quantitative analysis of the amino acid composition of soybean seeds as affected by climatic variables during seed filling. Amino acids were determined from seed samples taken ... -
Analysis of biodiversity attributes for extensive vegetated roofs in a semiarid region of central Argentina
(Elsevier, 2022-05)Vegetated roofs (VRs) contribute to the resiilience of cities by providing multiple ecosystem functions. A wide range of these benefits depends on the plant layer. Here, we hypothesized that increasing biodiversity ... -

Antibody detection against Kunitz-type protein in Fasciola hepatica experimentally infected sheep using enzyme-linked immunosorbent assay (ELISA)
(Taylor & Francis, 2023-11-14)Fasciolosis is a parasitic disease considered as emerging and neglected by the WHO. Sheep are highly susceptible to this disease, and affected flocks experience decreased productivity due to increased mortality, and the ... -
Are all edges equal? Microclimatic conditions, geographical orientation and biological implications in a fragmented forest
(Elsevier, 2019-08-01)In fragmented forests the edges experience changes in microclimatic conditions, which are referred to as “abiotic edge effect”, and differ according to geographical orientation and season. These microclimatic changes could ... -
Assessing the Impact of Ramularia Leaf Spot on Barley: Prospects for Fungicide Protection Strategies and Weather-Based Prediction Models in Argentina
(Wiley, 2025-04)Ramularia leaf spot (RLS), caused by the fungus Ramularia collo-cygni (Rcc), has become a threat to barley production in Argentina and the world, causing grain yield and quality losses. Characteristics of the pathogen such ... -
