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

Abstract

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.

Rootstock x environment interaction shapes shoot system phenotypic variation in grafted ‘Chambourcin’

Recent advances in phenomics and transcriptomics have the enhanced capacity for understanding how clonally propagated perennial crops like grapevines respond to their environments seasonally and over the course of multiple years. Because most grapevines are grafted, above-ground grapevine traits reflect scion genotype and its interaction with the local environment. In addition, traits expressed by the scion reflect rootstock genotype and how that rootstock is interacting with its environment seasonally and across years. To investigate rootstock x environment interaction on shoot systems in grafted grapevines we characterized comprehensive phenotypic variation in an experimental vineyard in Mount Vernon, Missouri, USA where the grapevine cultivar ‘Chambourcin’ is growing on its own roots and is grafted to three different rootstocks (‘1103P’, ‘3309C’, ‘SO4’).

NEW TREATMENTS FOR TEMPRANILLO WINES BY USING CABERNET SAUVIGNON VINE-SHOOTS AND MICRO-OXYGENATION

Toasted vine-shoots as enological additive represents a promising topic due to their significant effect on wine profile. However, the use of this new enological tool with SEGs varieties different than wine and combined with others winemaking technologies, such as micro-oxygenation (MOX), has not been studied so far, despite this combination could result in wine with high chemical and organoleptic quality.

Effects of the biodynamic preparations 500 and 501 on vine and berry physiology, pedology and the soil microbiome

In the pursuit of increasing sustainability, climate change resiliency and independence of synthetic pesticides in agriculture, the interest of consumers and producers in organic and biodynamic farming is steadily increasing. This is in particular the case for the vitivinicultural industry in Europe, where more and more producers are converting from organic to biodynamic farming. However, clear scientific evidence showing that biodynamic farming improves vine physiology, vine stress resilience, berry or wine quality, or is more sustainable for the environment is still lacking although this issue has been addressed by several research teams worldwide.
