The importance of pruning to the quality of wine grape fruits (Vitis vinifera L.) cultivated under high-altitude tropical conditions

The importance of pruning to the quality of wine grape fruits (Vitis vinifera L.) cultivated under high-altitude tropical conditions

Since 1998, the Ain-Karim Vineyard has been growing different grape varieties for the production of high-altitude tropical wines in the municipality of Sutamarchan, located in the Alto Ricaurte region of Boyaca (Colombia). Pruning is used to limit the number and length of branches, generating a suitable balance between plant vigor and production; thereby, regulating fruit quantity and quality and ensuring reserves for the subsequent production. This study aimed to evaluate the effect of three pruning types (short = two buds on two spurs; long = five buds on three spurs and mixed = combination of short and long pruning types) on the fruit quality of V. vinifera, Cabernet Sauvignon and Sauvignon Blanc varieties. To accomplish this, a completely randomized two-factor design was used. Physicochemical variables of fruit quality (fresh cluster weight, water content, total soluble solids (TSS), total titratable acidity (TTA), technical maturity index (TMI), and pH) were determined at harvest. The long pruning type presented the highest values for the fresh cluster weight and TSS of the fruits from both varieties and a higher TMI in the Cabernet Sauvignon variety. These results indicate that, under the conditions of the vineyard, long pruning is the most suitable.

En la Región del alto Ricaurte desde 1998, en el municipio de Sutamarchán, Viñedo Ain-Karim, Boyacá (Colombia), se cultivan diferentes variedades de uva para la producción de vinos tropicales de altitud, con la práctica de la poda se busca limitar el número y longitud de los pámpanos, para generar un balance adecuado entre el vigor y la producción, regulándola en calidad, cantidad de frutos y reservas que aseguren la siguiente producción. El objetivo de este estudio fue evaluar el efecto de tres tipos de poda (corta = dos yemas en dos pulgares; larga = cinco yemas en tres pitones y mixta = combinación de poda corta y larga), sobre la calidad del fruto V. vinifera, variedades Cabernet Sauvignon y Sauvignon Blanc. Para tal fin, se realizó un diseño estadístico completamente al azar en forma bifactorial, en la vendimia (cosecha), se determinaron variables fisicoquímicas de calidad del fruto (peso fresco de racimo, contenido de agua, sólidos solubles totales (SST), acidez total titulable (ATT), pH e índice de madurez técnica (IMT). La poda larga presentó en los frutos, para las dos variedades, los valores más altos en peso fresco de racimo y SST y en la variedad Cabernet Sauvignon un IMT más alto. Estos resultados implican que para las condiciones del viñedo, la poda larga es la más apropiada.
