| In 2006 wurde ein weinbaulicher Feldversuch zum Vergleich verschiedener Bewirtschaftungssysteme (integriert, biologisch-organisch, biologisch-dynamisch) an der Hochschule Geisenheim University in Geisenheim, Rheingau, etabliert. Ertrag, Schnittholzgewicht und Zuckergehalt der Moste unterschied sich signifikant zwischen den Bewirtschaftungssystemen in einem Untersuchungszeitraum von 7 Jahren (2006-2012). Die integrierte Variante zeigte ein signifikant höheres Schnittholzgewicht, einen signifikant höheren Ertrag und signifikant niedrigeren Zuckergehalt des Mostes im Vergleich zu den beiden biologischen Systemen. Zwischen der biologisch-organischen und der biologisch-dynamischen Variante wurde kein Unterschied beobachtet. Weiter unterschieden sich die... |

| World wide many wine farms are converting into organic or biodynamic viticulture. The main reasons are better wine quality and healthier wine with the long-term aim of sustainability in viticulture. In 2005 a long-term study started in Geisenheim. The objective of the research program is to investigate, compare and optimise the techniques of integrated, organic and particularly biodynamic wine production in terms of resource protection and food quality. The goals of this study are to look at the effects on the biological and microbial activity in the soil, the vegetative and generative growth of the vine, microbiology, the grape and wine quality and the sustainability of the three viticultural systems. |

| Der ökologische sowie Biodynamische Weinbau können sich über hohe Zuwachsraten der letzten Jahre erfreuen. In einem Projekt namens INBIODYN wurde mit der Rebsorte Riesling (Vitis vinifera L.) in Geisenheim, Rheingau, die Auswirkungen der integrierten (gute fachliche Praxis), biologisch-organisch (EU VO 834/07 plus ECOVIN Standard) und biologisch-dynamisch (EU VO 834/07 plus DEMETER Standard) Wirtschaftsweise auf die Wüchsigkeit, die physiologische Aktivität der Pflanzen, die Traubenstruktur und die Trauben-, Most -und Weinqualität unter Praxisbedingungen untersucht werden. Die Ergebnisse zeigten u.a. eine Veränderung des Geiztriebswachstums, welches das Mikroklima in der Traubenzone negativ beeinflussen kann. Die Geiztriebblattfläche unter... |

| Based on a field trial, the impact of three different viticultural management practices on photosynthetic activity of Vitis vinifera cv. Riesling were compared. The vines were planted in 1991 at Geisenheim (Rheingau, Germany) and the different management practices i.e. integrated (good agricultural practice), organic (EU VO 834/07 and ECOVIN standard) und biodynamic (EU VO 834/07 and DEMETER standard) were established in 2005. Even though all treatments received the same level of nutrients and water the initial measurements of photosynthetic activity differed tendentially. The integrated and biodynamic treatment showed a slightly higher degree of light saturation, as well as photosynthetic activity, compared to the organic treatment. |

| Based on a field trial, the impact of three different viticultural management strategies on vigour and grapevine physiology of Vitis vinifera cv. Riesling was compared. The vines were planted in 1991 at Geisenheim (Rheingau, Germany) and three different management strategies i.e. integrated (code of good practice), organic (European Union Regulation 834/07 and ECOVIN standard) and biodynamic (European Union Regulation 834/07 and DEMETER standard) were established in 2006. Even though all treatments received the same level of nutrients and water a decline in vigour, expressed as lateral growth, was observed for the organic and biodynamic treatment during three seasons (2010 to 2012). During dryer conditions (2011) a reduction of physiological activity... |
