Assessment of cold tolerance at early developmental stages and allelic variation at candidate genes in South American rice germplasm
(Springer, 2014-06)Rice is susceptible to cold during early developmental stages. Most tolerant cultivars have been developed for other conditions than those occurring in South America’s rice growing areas, or their grain type is not suitable ... -
Cold acclimation and freezing tolerance in three Eucalyptus species: A metabolomic and proteomic approach
(Elsevier, 2020-05)The ability of plants to cope with frost events relies on the physiological and molecular responses triggered by cold temperatures. This process, named acclimation, involves reprogramming gene expression in order to adjust ... -
Cold stress tolerance during early growth stages of naturalized Helianthus petiolaris populations
(2016-07)In the last 10 years the sunflower crop area of Argentina has shifted towards the Southwest as a result of the expansion of soybean cultivation. Early sowings require greater tolerance to low temperatures in order to ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
(Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Estrés hídrico y salino como medio para mejorar la tolerancia al frío en olivos jóvenes
(EEA San Juan, INTA, 2011-11-14)Investigadores de la EEA San Juan realizaron un ensayo en un olivar joven de las variedades Arbequina y Barnea. Después de aplicar dos niveles distintos de estrés hídrico y dos variantes de estrés salino, determinaron ... -
Phenotyping and QTL mapping for cold tolerance at the germination and seedling stages in Argentine temperate rice
(Springer, 2020-07)In Argentina, the yield potential of rice (Oryza sativa L.) under suboptimal temperatures of temperate regions and during early sowing in tropical regions depends on its low-temperature germinability (LTG) and subsequent ... -
Registro de temperaturas actinotérmicas: rangos de temperaturas de heladas en superficie en San Pedro, provincia de Buenos Aires (Argentina)
(2018)En el noreste de la provincia de Buenos Aires, la concentración de productores hortícolas se ubica en Zárate, San Nicolás y Baradero. En dicha región, la ocurrencia de heladas invernales y primaverales puede producir daños ... -
Repeated maternal separation: Alcohol consumption, anxious behavior and corticosterone were reversed by a non-pharmacological treatment
(Elsevier, 2019-12-29)Adverse events in early life have been related to a maladaptive stress response during adulthood, which could predispose individuals to psychiatric and physiological disorders. The purpose of this work was to study the ... -
Tolerancia a frío en estadios tempranos del desarrollo en arroz: caracterización fenotípica de germoplasma de origen diverso y variación alélica en genes candidatos
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2011-10)El arroz es una especie de clima templado-subtropical a subtropical susceptible a bajas temperaturas durante las etapas iniciales del desarrollo. Si bien en el mundo existen materiales tolerantes, actualmente no se dispone ... -
Winter injury to grapevine secondary phloem and cambium impairs budbreak, cambium activity, and yield formation
(Springer, 2019-11-11)Vitis vinifera is a species of temperate origin that reactivates the dormant secondary phloem from the previous year at the resumption of growth in spring. Following harsh winters, grapevines may display a set of symptoms ...
