| description | Water is a major component of plants that directly and indirectly affects physiological processes. One of the consequences of a hydric deficit in the pear fruit is modification of the aroma. No information exists on the effect of a water deficit on the sensory profile and volatile composition of this species. The objective was to determine the production of volatiles in the harvest and post-harvest of pear var. Triumph of Vienna (Pyrus communis L.) with regulated deficit irrigation (RDI). The irrigation treatments consisted of the application of water regimes that were 100 (Control), 74 and 48% of the ETc during the rapid fruit growth period. The rest of the season plants were irrigated at 100%ETc. In the deficit treatments, there were no significant reductions with respect to the control in the quality of the fruits, obtaining a water savings in 74 and 48%ETc of 26 and 40%, respectively. The esters were the volatile compounds that contribute greatly to aroma, which increased steadily during the climacteric phase. Under the limited water conditions, watering with regulated, deficit doses obtained production that was similar to that of well-watered crops, provided that it was carried out in the phenological stage of low sensitivity and that the tolerance limits of stress were not exceeded. |

El agua es el componente mayoritario de la planta que afecta directa e indirectamente los procesos fisiológicos. Uno de los efectos del déficit hídrico en el fruto de la pera es la modificación del aroma y no existe información sobre el efecto del déficit hídrico en el perfil sensorial y composición de volátiles de esta especie. El objetivo fue determinar la producción de volátiles en la cosecha y poscosecha del peral var. Triunfo de Viena (Pyrus communis L.) con riego deficitario regulado (RDR). Los tratamientos de riego consistieron en la aplicación de láminas de agua correspondiente al 100 (Control) 74 y 48% de la ETc, durante el periodo de crecimiento rápido del fruto, el resto de la temporada se regaron al 100% de la ETc. En los tratamientos deficitarios no hubo reducciones significativas respecto al control en la calidad de la fruta, obteniéndose un ahorro de agua en 74 y 48%ETc de 26 y 40%, respectivamente. Los ésteres fueron los compuestos volátiles con mayor contribución al aroma que aumentaron de forma constante durante la fase del climaterio. En condiciones limitantes de agua, regar con dosis deficitarias controladas permite obtener producciones similares a las de un cultivo bien regado, siempre que se realice en el estado fenológico de baja sensibilidad y los límites tolerables de estrés no se superen.
