Effects of environmental factors and vineyard pratices on wine flora dynamics

Abstract

The intensification of t vineyard practices led to an impoverishment of the biological diversity. In vineyard management, the reflection to reduce pesticides uses concerns mainly the soil management of the vineyard, and often focuses on flora management in the inter-row. The goal of the present study is to gain more knowledge on the dynamic of vineyard flora, including relationships with environmental factors and soil practices. Assessment of floristic diversity was carried out for 5 fields of the research program PEPSVI in Alsace (France) on an area of 500 m ² within each of the fields. Soil management was either integrated or organic. Within each field, species richness was determined for the row (UR), the grassed inter-row (GIR), and the tilled inter-row (TIR) three times during each vine-growing season in 2014 and 2015. ANOVA tests were performed on data.

First we observed an average of 54 different species in the fields per year and that there are no significant differences between the different soil managements. The highest value belongs to organic soil management. The average species richness in organic fields is the highest in GIR (respectively 21 and 22 species in 2014 and 2015) and in UR (respectively 19 and 18 species in 2014 and 2015) and there is no significant difference between GIR and UR and between 2014 and 2015. The flora developed more considerably in the GIR (22 species) than UR (19 species) and less in TIR (16 species).

The results of the study showed also that superficial tillage i.e. scraping or harrowing, helps flora emergence and increases species richness (21 species in average against 14 in average for the other soil managements). The environment has also to be taken into account. Surrounding vegetation of the field influences significantly the species richness, (30 more species in the year for the most favorable environment). Next steps of the study will be the analysis of distribution of flora families and Raunkiær’s life.

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. The objective of this work is to assess the mesoclimate of the Atlantic region of Uruguay and to determine the effect of topography and the ocean on temperature and consequently on Tannat grapevine behavior.

Territorial delimitation of viticultural “Oltrepo Pavese (Lombardy)” using grape ripening precocity

L’Oltrepò Pavese est une zone de collines de la Lombardie, région située au nord de l’Italie avec un vignoble qui s’étend sur près de 15 000 ha. Cette zone représente la plus grande aire de production de la région et une des A.O.C. les plus étendues de tout le pays. Les cépages les plus cultivés, même historiquement, sont autochtones : la Barbera et la Croatina utilisés pour la production de vin rouge «Oltrepò» et le Pinot noir pour la production de vins mousseux. Pour le zonage viticole de cette A.O.C., il a été pris en considération: le climat, les sols, les caractéristiques viti-vinicoles.

Red wines from southwest France, Lebanon and South Korea: study of phenolic composition and antioxidant and biological activities according to grape varieties and winemaking processes

The phenolic compounds present in the wine are responsible for reducing the risk of developing chronic diseases (cardiovascular, cancer, diabetes, Alzheimer …) because of their antioxidant activities and the presence of nutraceutical molecules with targeted biological activities. Polyphenols not only contribute to the “French paradox” but also contribute to give the wine its color, structure, aroma and allow a long-term preservation.
