Merr.], abastece más del 59% de la demanda global de proteína (Pr) y aceite (Ac) vegetal. El cultivo se realiza mayoritariamente bajo secano y suele atravesar eventos de alta temperatura y/o ... -
Estrategias adaptativas de Cenchrus ciliaris L. frente al estrés hídrico y su impacto en la calidad forrajera
(Asociación Argentina de Producción Animal, 2022-11-16)El objetivo de este trabajo fue estudiar las estrategias adaptativas morfo fisiológicas, que contribuyen a la tolerancia al estrés hídrico en genotipos contrastantes de C ciliaris L y su impacto sobre la calidad forrajera. -
Evaluación de Procesos Fisiológicos Involucrados en la Fotosíntesis Bajo Condiciones de Estrés Térmico e Hídrico en Soja
(Red Raíces de Ecofisiología MINCyT y el Área Estratégica de Ecofisiología del INTA, 2017-09-28)Actualmente se discute si el estrés térmico (ET) o el estrés hídrico (EH) limitan la fotosíntesis en los cultivos debido al cierre de estomas, a cambios metabólicos o a la combinación de ambos factores (Chaitanya et al., ... -
Evaluación morfológica del cultivar de buffelgrass “Lucero INTA-PEMAN” en condiciones de sequía
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)En la búsqueda de nuevos cultivares nacionales mejor adaptados a las restricciones edafo-climáticas presentes en el noroeste argentino, principalmente estrés por sequía y salinidad, un híbrido de buffelgrass (Cenchrus ... -
Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor
