Could the Interaction between Arbuscular Mycorrhizal Fungi and Biostimulants Improve the Plant Physiological Status of Prosopis alba Seedlings?
Santacruz-García, Ana Carolina; Gomez, Adriana Teresita; Senilliani, Maria Gracia; Guzmán, Analía del Valle; Sagadin, Monica Beatriz; Ewens, Mauricio; Frías, Rodrigo Sebastián; Coria, Cristian; Gómez, Joaquín; Nazareno, Mónica Azucena (MDPI, 2022-10)This study aimed to evaluate the synergy between arbuscular mycorrhizal fungi (AMF) and foliar biostimulant applications (phytoextracts) on an important Argentinian forest native species (Prosopis alba) during the nursery ... -
Development of an analytical method to determine malondialdehyde as an oxidative marker in cryopreserved bovine semen
Yonny, Melisa Evangelina; Reineri, Pablo Sebastian; Palma, Gustavo Adolfo; Nazareno, Mónica Azucena (Royal Society of Chemistry, 2015)Frozen sperm is widely used in artificial insemination of cattle as well as other animal species. As a consequence of the freezing and thawing processes of semen, an excess of reactive oxygen species (ROS) are formed. ROS ... -
Dried distiller´s grains plus solubles supplementation improves low-quality tropical grass utilization on beef steers = Suplementação de grãos de destilação secos com solúveis melhora a utilização de grama tropical de baixa qualidade para novilhos de corte
Hernandez, Olegario; Lopez, Agustin; García, Elisa Mariana; Nazareno, Mónica Azucena; Arroquy, Jose Ignacio (Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2022)This study was designed to evaluate the effect of corn dried distiller´s grains (DDGS) supplementation on feed intake, total tract digestibility, and ruminal fermentation of beef steers fed low-quality Guinea grass ... -
Eficiencia fotoquímica máxima e índice de potencial fotosintético en plantas de melón (Cucumis melo) tratadas con bajas temperaturas
Rodriguez Torressi, Ariel; Yonny, Melisa Evangelina; Nazareno, Mónica Azucena; Galmarini, Claudio Romulo; Bouzo, Carlos Alberto (Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2014)La fluorescencia de la clorofila se utiliza para determinar la eficiencia fotoquímica de las plantas ante diferentes condiciones ambientales. Existen índices como Fv/Fm y PI abs que son indicadores indirectos del rendimiento ... -
Exploring the biological activity of condensed tannins and nutritional value of tree and shrub leaves from native species of the Argentinean Dry Chaco
García, Elisa Mariana; Cherry, Nicole; Lambert, Barry D.; Muir, James P.; Nazareno, Mónica Azucena; Arroquy, Jose Ignacio (2017)BACKGROUND: Tropical tree or shrub leaves are an important source of nutrients for ruminants and a potential source of biologically active compounds that may affect ruminalmetabolism of nutrients. Therefore, eightwoody ... -
How Does Mycorrhiza Interact with Different Levels of Fertilization on Prosopis alba?
Senilliani, Maria Gracia; Guzmán, Analía del Valle; Gomez, Adriana Teresita; Santacruz-García, Ana Carolina; Sagadin, Monica Beatriz; Ewens, Mauricio; Coria, Cristian; Gómez, Joaquín; Frías, Rodrigo Sebastián; Nazareno, Mónica Azucena (MDPI, 2022-10)This study assessed how the interactions between chemical fertilization levels and arbuscular mycorrhizal fungus species (AMF) affect the seedling’s morphology and biochemical traits in Prosopis alba. Subsequently, the ... -
Measurement of malondialdehyde as oxidative stress biomarker in goat plasma by HPLC-DAD
Yonny, Melisa Evangelina; García, Elisa Mariana; Lopez, Agustin; Arroquy, Jose Ignacio; Nazareno, Mónica Azucena (2016-11)During the cattle breeding, the animals are exposed to stressful conditions (confinement, competition, extreme temperatures, pathogens); these have been associated to the increase of reactive oxygen species that attack ... -
Oxidative stress mitigation in horticultural crops using foliar applications of Ilex paraguariensis extract: a dose-dependent study
Yonny, Melisa Evangelina; Toscano Adamo, Maria L.; Rodriguez Torressi, Ariel; Reversat, Guillaume; Binqging, Zhou; Oger, Camille; Galano, Jean-Marie; Durand, Thierry; Vigor, Claire; Nazareno, Mónica Azucena (Wiley, 2023-11)Abiotic stress has been shown to induce the formation of reactive oxygen species (ROS) in plant cells. When the level of ROS surpasses the capacity of the endogenous defence mechanism, oxidative stress status is reached, ... -
