Biostimulants as forest protection agents: Do these products have an effect against abiotic stress on a forest native species? Aspects to elucidate their action mechanisms
Santacruz-García, Ana Carolina; Senilliani, Maria Gracia; Gomez, Adriana Teresita; Ewens, Mauricio; Yonny, Melisa Evangelina; Villalba, Gastón Fernando; Nazareno, Mónica Azucena (Elsevier, 2022-10)Projections of climatic change pose a challenging scenario for the management and adaptation of ecosystems. It is expected that forests around the world will be exposed to severe stress conditions such as imposed for ... -
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 ... -
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 ... -
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, ... -
Supramolecular solvent-based high-throughput sample treatment for monitoring phytohormones in plant tissues
Yonny, Melisa Evangelina; Ballesteros-Gómez, Ana; Toscano Adamo, Maria L.; Rodriguez Torressi, Ariel; Nazareno, Mónica Azucena; Rubio, Soledad (2020-11)Quantification of endogenous hormones in plants is essential to understand their growth, development and response to biotic and abiotic stresses. However, it is challenging to develop high-throughput sample treatments from ...
