Effect of row direction in the upper part of the hillside vineyard of Somló, Hungary


Hillside vineyards have a great potential to produce world class wines. The unique microclimate lead to the production of rich, flavory wines. However site development needs land clearing, rock removal, terracing, engineered water collecting drainage system. Because of the very high cost of establishment every part of the plantation needs to be very carefully planned, designed and established. Row direction has a pronounced effect on sunlight interception. The amounts of direct light are absorbed by the canopy is influenced by the row direction. Commonly known that greater amounts of light absorbed by the canopy the mid-morning and mid-afternoon in rows directed north-south compared to east –west. But information on the effects of row direction on the fruit quality of grapevines are limited. Therefore we established an experiment on hill Somló to determine if row direction has role to improve the quality or not. We have 24 % less yield, higher sugar content, lower acid content in row direction east-west compared to the north-south in 2006. Similar results were obtained in 2007 as well. The catechin contents differed statistically only among other poliphenols between the row directions. The wine analysis and organoleptical evaluation showed that the east-west oriented rows produced better quality of wine in 2006. We have very extreme weather conditions in 2007 in July and August therefore we have not got the same picture in 2007 like in 2006. Even if we have only two year results the clear influence of row direction pictured on the quality of the yield.

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.
