Para Determinar

La producción y calidad de la uva para elaboración de vino, se modifican con las prácticas culturales que se realizan en el viñedo. La poda es una de las prácticas que buscan mejorar la calidad final de mostos y vinos. Con la investigación se buscó conocer el efecto de tres tipos de poda (corta, larga y mixta) en la evolución de los componentes de la calidad, durante la maduración de frutos de Vitis vinifera L. var. Sauvignon Blanc, en el municipio de Sutamarchán-Boyacá, Colombia. Se recolectaron, cada quince días, aleatoriamente 20 bayas, desde el inicio del envero, hasta la maduración, para determinar el comportamiento de los sólidos solubles totales (SST), acidez total titulable (ATT) e índice de madurez técnica (IMT). Con la poda larga se alcanzó el mayor contenido de azúcares (22,76ºBrix) y el más alto IMT (3,42), la acidez total titulable (ATT) disminuyó con el desarrollo del fruto, obteniéndose en el momento de la vendimia una acumulación de ácidos orgánicos de 6,88 g L-1. Los tratamientos no afectaron el contenido de SST; mas si hubo diferencias significativas entre ATT e IMT. La poda larga produjo los frutos con los valores más adecuados, de calidad (SST, ATT, IMT) requeridos para la elaboración de vinos tropicales de la variedad Sauvignon Blanc, en la localidad del estudio.

Berry Composition

A trial was conducted during the 2005–2006 season in order to determine the effects of different leaf-to-fruit ratios on yield components and fruit composition in four Vitis vinifera L. cultivars. The treatments consisted of selecting shoots of four lengths (>1.3 m, 1.3–0.8 m, 0.8–0.4 m, and <0.4 m) with two crop levels (1–2 clusters/shoot), which allowed defining eight ratios. Berry composition and yield components were measured. The treatments affected the accumulation of soluble solids in “Sauvignon blanc”, “Cabernet Sauvignon”, and “Syrah”, delaying it as the ratio decreased. All yield components were affected in “Sauvignon blanc”, while bunch weight and the number of berries per bunch were altered without a clear trend. None of the yield components were affected in “Cabernet Sauvignon”, while the lowest ratio presented the lowest number of berries per bunch in “Syrah”. Total polyphenol index (TPI) was affected in “Carmenère” without a clear trend. A highly significant correlation was found between shoot length and leaf area in all studied cultivars. As the ratio increased, the shoot lignification increased in “Sauvignon blanc”. However, studies must be conducted during more seasons to establish better conclusions about the effects of leaf-to-fruit ratios on yield and fruit composition.

Grape Varieties

The cultivation of grapes for the production of wine at altitudes between 2,200 and 2,600 masl started in the department of Boyacá in 1982. Quality wines are produced by the Ain Karim Vineyard in Ricaurte High. It is necessary to have wine grapes that possess suitable organoleptic compounds at harvest in order to guarantee quality grape must that can be converted into wine. For this, it is necessary to have a suitable ratio between the inflows and the outflows and to guarantee production, quality and vegetative sustainability over time, conserving the equilibrium and benefiting the productive potential of the vineyard. This study aimed to evaluate the productive and vegetative balance effect in the wine grape varieties (Vitis vinífera L.) Cabernet Sauvignon and Sauvignon Blanc in Sutamarchán-Boyacá, considering different pruning types (short, long, and mixed). A bifactorial, completely random statistical design was used. At the time of harvest, the fruit production and pruned wood were evaluated. The long-pruned vines presented the best behavior and the most balanced inflow/outflow ratio, while Sauvignon Blanc demonstrated a better productive yield. Meanwhile, the short and mixed prunings presented the better values for the ravaz index, indicating that they are more suitable for the conditions of the region, allowing for sustainability during the productive cycles of the wine grapes.
