Monitoring arthropods diversity in the “Costières de Nîmes” viticulture landscape


Biodiversity loss in agrosystems is partly due to landscape simplification (field enlargement, hedgerows removal…) that led to a loss of heterogeneity of the overall landscape. The aim of this study is to compare biodiversity of different habitats and landscape configurations in order to target strategic conservation actions and their locations in viticulture landscapes to improve biodiversity. The arthropods taxon has been used to evaluate biodiversity dynamics because of its high diversity and supposed ability to rapidly react to landscape dynamics. Arthropods are identified through the RBA method (Rapid Biodiversity Assessment). Arthropod diversity is evaluated in five different habitats and measured by species richness and Shannon index. Within four different radii (50, 100, 150 and 200 meters) around each arthropod sampling site, landscape composition (relative percentage of each land cover type), structure (variability and heterogeneity indexes) and diversity (Shannon index applied to landscape) were analyzed through a Geographic Information System of land cover based on aerial photographs.

The results show significant differences in arthropod diversity among habitats. Cultivated habitats show lower values of diversity than semi natural ones. The landscape approach highlighted negative correlations between arthropod richness and proportion of fruit orchards at all radii. At the smallest scale (50m radius) a positive correlation is found between arthropod diversity and interstitial spaces (plot edges, headlands, roadsides…). Hence, semi natural habitats and non cultivated areas appear to play a major role in the preservation of arthropod diversity in agricultural landscapes. According to these results, landscape and biodiversity actions will be performed at the “Appellation” scale focusing on improving the ecologic connectivity between semi natural habitats supporting biodiversity.

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.
