Agronomic behaviour of a native grapevine cultivar from the North of Spain (Vitis vinifera L.) in a mountain viticulture area and in a coastal zone


A work involving the finding, the description and the recovery of old grapevine varieties from the north and north east of Spain was begun in the CSIC in the year 1987. Among the red varieties that were found, the Verdejo Negro stood out because of its high quality. Different previous works (Martínez and Pérez 1999, 2000; Martínez et al. 2004, Santiago et al, 2003) have allowed us to know this cultivar from the ampelographic, agronomic and molecular point of view.
The aim of this study was to compare the agronomic behaviour of Verdejo Negro in two different climate areas from North Spain: one from a mountain viticulture area and other from a coastal one. In each of these areas we have an experimental plot. The first one is placed in western south of Asturias region; it is located in the slope of a mountain and has an altitude of about 506 meters with a strong slope; the geological base of the soil is formed basically by shale, sandstone and quartzite. The stocks were planted in 1991. The second plot is located in the south of Galicia region, near from the Atlantic coast, in an area without slope and with an altitude of about 35 meters. The geological bases of the soil are glandular orthogneis. The stocks were planted in 1993. In both cases the plants are grown en espalier, but pruning methodology is different and adapted to the conditions of the two areas studied. In the mountain plot pruning is made using a Guyot system and in the littoral one the Sylvoz system is used.
During four years (2002, 2005, 2006 and 2007) several agronomic parameters were measured such as the fertility rate, weight, length and width of bunches, probable alcoholic grade, must yield, pH and total acidity of the must.
The results showed that for some parameters, such as probable alcoholic grade and pH, there were no significant differences between plots, but for other parameters, as for example fertility rate, grape production per plant, must yield and total acidity, significant differences were found.

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.
