La integración de variables referentes al clima, la litología y la morfología del relieve y el suelo en la D.O. Ca Rioja permite la configuración de un modelo a través de cuya validación se obtiene la delimitación de zonas vitícolas. A través del análisis estadístico (Clasificación Automática, AFD, ACP,…) se eliminan las variables del clima que aportan información redundante, lo que permite la constitución de un modelo que con dos únicas variables (ETO e Índice de Costantinescu) explica el 88 % de la varianza y partir de el que se configura una cartografía en seis zonas climáticas vitícolas (Fig.1).
La litología es valorada a través de agrupaciones litológicas cuya cartografía da lugar a diecinueve subzonas con vocación vitícola diferenciada (Fig. 4). Las variables referentes a la morfología del relieve y el suelo son valoradas a través del concepto de Serie de Suelos (Fig. 7). El tratamiento de la información por un Sistema de Información Geográfica (GIS) da como resultado la cuantificación de los contenidos y la posibilidad de su tratamiento estadístico. El resultado es un modelo con resultado cartográfico cuyas unidades son evaluadas desde el punto de vista vitícola por un sistema paramétrico aplicado a la unidad taxonómica principal y adaptado a las condiciones ecológicas particulares de la viña que da como resultado cinco clases (Fig. 10). La validación de los resultados mediante su comparación con las unidades cartográficas anteriormente definidas se realiza a través de variables relacionadas con la distribución superficial y el rendimiento en conjunto y por variedades. (Tabla 4).

The integration of variables concerning the climate, lithology, morphology of the relief and the soils in the Denomination of Origin (D.O.) Ca Rioja permits for the configuration of a model from which the demarcation of viticultural regions are obtained after validation. By means of statistical analysis (automatic classification, AFD, ACP…), redundant climatic variables are eliminated, which permits for the construction of a model with only two variables (ETO and the Index of Constantinescu) that can explain 88% of the variation. From this analysis, a map with six viticultural climate zones was formed (Fig. 1). The lithology is valued by means of Iithological groupings, whose mapping shows nineteen subzones where land is dedicated to viticulture (Fig. 4). The variables concerning the morphology of the relief and the soils were appraised by means of the Soil Series concept (Fig. 7). Treatment of this information with a Geography Information System (GIS) provides results on the quantification of the contents and the possibility of statistical analysis. The result is a model with cartography properties, whose units are evaluated from a viticultural point of view by a parametric system, applied the principal taxonomic unit and adapted to particular ecological conditions in the vineyard. Five classes were the result (Figure 10). Validation of the results by comparison with cartographies units described previously was realized through variables related to the distribution or land area and overall vineyard productivity or varietal productivity (Table 4).

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
