El uso de microorganismos biocontroladores para el manejo de enfermedades ... -
Selección de materiales tolerantes a la sequía evaluando respuestas fisiológicas en una población de RILs con parentales silvestres
(Centro de Ingenieros Agrónomos General Cabrera, 2022-09-15)La sequía es una limitación ambiental devastadora que afecta la calidad y productividad de maní. Las áreas de cultivo propensas a sufrir sequía van en incremento, con un pronóstico de aumentos en la frecuencia y gravedad ... -
Selecting salt-tolerant clones and evaluating genetic variability to obtain parents of new diploid and tetraploid germplasm in rhodesgrass (Chloris gayana K.)
(2013-01)We evaluated survival percentage under salt stress in 46 diploid and tetraploid clones of rhodesgrass (Chloris gayana K.) with the aim of obtaining salt tolerant clones. Fifteen clones were selected at 600 mM NaCl under ... -
Sequencing of two Sunflower chlorotic mottle virus isolates obtained from different natural hosts shed light on its evolutionary history
(Springer, 2013-02)Sunflower chlorotic mottle virus (SuCMoV), the most prevalent virus of sunflower in Argentina, was reported naturally infecting not only sunflower but also weeds. To understand SuCMoV evolution and improve the knowledge ... -
