Vine spacing on cv. Tempranillo in the Appellation of Origin Cigales (Spain): Agronomy and quality effects

Abstract

Abstract. This paper studies the vegetative, productive and qualitative behavior of the Tempranillo variety, vertically trellised trained, according to a placement of vines with three different distances (1.04, 1.40 and 1.80 meters) in the row and a common distance between rows (2.40 meters), in order to determine the most suitable vine distance for the growing conditions. The experimental test has been developed for the period 2007-2011 in the Appellation of Origin Cigales, in Valladolid (Spain). The reduction of vine distance has favored the vegetative growth, through the shoot weight, while the grape yield has been slightly higher in the intermediate vine distance, 1.40 m, through the cluster weight. Ravaz index showed some increase with the increasing of vine distance, derived from the decrease of pruning wood. In qualitative terms, the variation of the vine distance did not significantly modify the basic composition of the grape. Therefore, the choice of the vine distance involves the convenience to assess both potential effects in terms of production and economic objectives of the new plantations, in accordance with the characteristics of each growing situation.

Effect of different viticultural techniques on the qualitative and quantitative characters of cv. Xinomavro under vineyard conditions in Naoussa

“…The total soluble solids concentration was higher in the density-top treatment, and with a statistically significant difference compared the other treatments. These results are not in agreement compared to results from a previous study [14], in which the study of the plant density of grape cultivar Tempranillo showed that the pH and total soluble solids exhibited no difference between the different plant densities. The result of the present study could be due to that fact that the vines collected from the density-top treatment are located at the top of the slope.…”
