| dc.description | A bi-factorial experiment was conducted during the 1999-2000 season at Alto Jahuel, Chile. The effects of three crop levels (100, 66 and 33%) and three levels of clusters sunlight exposure (normal, shaded and exposed) on Cabernet-Sauvignon yield components and berry and wine composition and quality were studied. All the treatments were harvested the same day, with a more advanced over ripe degree on the treatments with smaller crop level and greater well illuminated leaf surface. Yield components as berry weight and cluster weight were not affected by crop level nor by microclimate. Must total acidity and color quality were higher, and wine pH and potassium content were lower in high cropped plants. No differences between microclimates were found on these variables. Microclimate influenced sugar content and wine color density. Main crop level effect was on the berry ripeness. This influence was closely related with exposed leaf surface and incidentEn un experimento que se llevó a cabo durante la temporada 1999-2000 en Alto Jahuel, Chile, se evaluaron los efectos de tres niveles de carga (100, 66 y 33%) y tres niveles de exposición de los racimos (normal, sombra y expuesto) sobre los componentes del rendimiento y la composición y calidad de las bayas y el vino de Cabernet- Sauvignon. Todos los tratamientos fueron cosechados en la misma fecha, con un grado de sobremadurez más avanzado en los tratamientos con menor nivel de carga y mayor superficie foliar bien iluminada. Los niveles de carga y de microclima no afectaron componentes del rendimiento como peso de bayas y peso de racimos. La acidez total del mosto fue superior y el pH, contenido de potasio y matiz menores en plantas con mayor carga. No hubo diferencias entre mostos provenientes de microclimas distintos en esos parámetros. El microclima influyó sobre el tenor de azúcar y la intensidad colorante del vino. El nivel de carga afectó principalmente a la madurez de las bayas y la magnitud de los efectos estuvo estrechamente relacionada con la superficie foliar expuesta y el nivel de radiación incidente. | en-US |
