| description | Buffelgrass (Cenchrus ciliaris L.) a native pasture species of Africa is widely used in arid regions because of its forage productivity and quality. It could become serious invasive species, not only for crops but also in natural vegetation. Buffelgrass is highly affected by low temperatures at all stages of its life cycle. The objective was to determine the behavior of three buffelgrass cultivars (Americana, Biloela, Texas 4464) under cold stress and define the critical temperatures. To determine the effect of cold stress on the plasma membrane, foliage damage and survival (regrowth), it was evaluated relative electrical conductivity (ECr) of leaves, percentage of foliar damage and the ability of regrowth after exposure to 2 temperatures (-5°C and -10°C) with 2 exposure times (4 and 7 hours). The results showed a higher percentage of foliar damage and greater ECr as temperature decreased and hours of exposure increased. A similar response was observed when survival (regrowth) was evaluated. There were no significant differences among cultivars in both temperature treatments and time when the regrowth was evaluated. |

El buffelgrass (Cenchrus ciliaris L.) es una especie forrajera nativa de África ampliamente utilizada en las regiones áridas debido a su productividad forrajera y calidad. En muchos casos puede convertirse en una especie invasora, no solo para los cultivos, sino también para la vegetación natural. El buffelgrass es afectado por las bajas temperaturas en todas las etapas del ciclo de vida. El objetivo del presente trabajo fue determinar el comportamiento de tres variedades de buffelgrass (Americana, Biloela, Texas 4464) ante condiciones de frío y definir las temperaturas críticas. Para determinar el efecto de estrés por bajas temperaturas sobre la membrana plasmática, daños de follaje y la supervivencia (rebrote), se evaluó la conductividad relativa (ECr) de hojas, porcentaje de daño foliar y la capacidad de rebrote después de la exposición de las plantas y plántulas a 2 temperaturas (-5°C y -10°C) durante 2 períodos (4 y 7 horas). Los resultados mostraron un mayor porcentaje de daño foliar y mayor conductividad relativa. Medida que disminuía la temperatura y aumentaba las horas de exposición. Una respuesta similar se observó cuando se evaluó la supervivencia (rebrote). No hubo diferencias significativas entre cultivares en ambos tratamientos de temperatura y tiempo cuando se evaluó el rebrote. EEA San Juan Fil: Parera, Victoria.
