| description | After harvesting, barley grains (Hordeum vulgare L.) can show dormancy and water sensitivity, which delays industrial use. Both effects depend on the barley genotype and environmental conditions during grain maturation. In order to analyze the effect of the average temperature and the total rainfall accumulated during and in the final third of the grain filling, on the dormancy and water sensitivity and the relationship between them, three cultivars of barley were sownin four dates in 2009 and two in 2011. Temperature and daily rainfall were recorded from anthesis to physiological maturity. The dormancy was evaluated as germination at 12 days post physiological maturity and the water sensitivity as germination in water excess conditions at 100 days post physiological maturity. The variables that presented a higher correlation with germination and water sensitivity were average temperature and accumulated rainfall during grain maturity. Environments with average high temperature during grain filling, reduced dormancy, but on water sensitivity decrease was cultivar dependent. The increase of rainfall during grain filling, decreased dormancy, but increased water sensitivity in all three cultivars. |

Los granos de cebada (Hordeum vulgare L.) pueden presentar dormición y sensibilidad al agua poscosecha, que retrasan su utilización industrial. Ambas dependen del genotipo y del ambiente durante la maduración del grano. Con el fin de analizar el efecto de la temperatura media y las precipitaciones acumuladas durante y en el tercio final del llenado de grano, sobre la dormición y la sensibilidad al agua y la relación entre ellas, fueron sembrados tres cultivares de cebada en cuatro fechas durante el 2009 y dos durante 2011. Se registraron temperaturas y precipitaciones diarias desde antesis a madurez fisiológica. La dormición se evaluó como la germinación a los 12 días pos-madurez fisiológica y la sensibilidad al agua como la germinación en exceso de agua, a los 100 días pos-madurez fisiológica. Las variables que presentaron mejor correlación con germinación y sensibilidad al agua fueron la temperatura media y las precipitaciones acumuladas durante el llenado de grano. Ambientes con mayores temperaturas medias durante el llenado de grano disminuyeron la dormición, pero la disminución de la sensibilidad al agua dependió del cultivar. El incremento de las precipitaciones durante el llenado de grano disminuyó la dormición, pero aumentó la sensibilidad al agua en los tres cultivares.
