Evaluación de la tolerancia a estrés salino en genotipos novedosos de Buffel Grass (Cenchrus Ciliaris L.)
(Red Argentina de Salinidad, 2023-09-19)En Argentina, los suelos de ambientes cálidos áridos y semiáridos, se reportan como uno de los más afectados por sales en el perfil. El INTA viene realizando programas de mejoramiento genético en especies forrajeras ... -
Factors Affecting Tocopherol Concentrations in Soybean Seeds
(American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Fast classification system for drought tolerance in peanut and soybean
(Sociedade Brasileira de Fisiologia Vegetal (SBFV), 2022-09-06)Drought is one of the major limitations for agriculture. The direct selection of tolerant genotypes on the fields is time consuming due to the unpredictability of the environmental conditions. Our group use a physiological ... -
Fertilidad en plantas apomícticas facultativas de Cenchrus ciliaris L.
(Sociedad Argentina de Botánica, 2021-09-06)Cenchrus ciliaris L. es una especie forrajera perenne de crecimiento primavero-estival. Es alotetraploide segmental y se reproduce por apomixis apospórica seguida de pseudogamia. Las plantas sexuales son raras y escasas y ... -
In vitro selection and characterization of buffelgrass somaclones with different responses to water stress
(2017-08)Buffelgrass is a forage grass that reproduces mainly by apomixis. In species with this reproduction mode, in vitro selection allows the incorporation of alternatives in a breeding program. The aims were to define a protocol ... -
Individual and combined effects of drought and heat on antioxidant parameters and growth performance in Buffel grass (Cenchrus ciliaris L.) genotypes
(2018-11)Drought and heat stress are two critical threats to crop growth and sustainable agriculture worldwide. In the last decade, many studies focused on the response of crops to a single stress, nevertheless studying the response ... -
