Influence of cover crops in a Tempranillo vineyard grown under the edaphoclimatic conditions of the Appellation of Origin Rueda

Abstract

The way to manage the vineyard soils has certainly changed in Spain during the last years. Traditionally, the vineyards were tilled, but this growing technique has been replaced in some vineyards by the bare soil with herbicide. Also, soil cover crops have started to be applied in some vineyards. The competition between the roots systems of the vines and the cover crop can influence on the capacity and the conditions of the plants for water absorption, transport of photosynthesized products to the roots, etc. Consequently, the cover crop can affect the water supply to the vine. The objective of this trial has been to study the behaviour of the Tempranillo variety under different alternatives of soil management, analysing the vegetative-productive vine balance and its influence on the grape quality, as well as the soil water content and the dry matter produced by the cover crop species. The trial has been carried out along 2006 and 2007 on a Tempranillo/110R vineyard, vertical trellis trained with Royat cordon pruning, with 3.00 m x 1.25 m vine spacing. The soil has homogeneus sandy-loam structure from the surface to the 110 cm depth, where there is a ground water table. The experimental treatments have been the following: TIL, traditional tillage (2006 and 2007); BAR, barley (Hordeum vulgare) (2006 and 2007); LEG, Vicia monanthos (2006) and vetch (Vicia sativa) (2007); PER, resident vegetation (2006) and or perennial vegetation, fescue (Festuca orundinacea) and ryegrass (Lolium perenne) combination at 50% (2007). The use of cover crop species in the inter-row space has provoked highly significant differences among treatments in yield, depending on the cover crop species and the annual climatic conditions. Legume and perennial species have shown to be more water competitive towards the vines than the rest of cover crops applied, which has reduced yield and vegetative development and has increased the dry matter produced by this species with respect to the others. The influence of the soil management on grape quality has not been determinant, in such a way that it has depended on the annual conditions and the level of yield, as well as on the cover crop species

The future of DMS precursors during alcoholic fermentation: impact of yeast assimilable nitrogen levels on the contents of DMSp in young wines

Some red wines develop a “bouquet” during ageing. This complex aroma is linked to quality by wine tasters1. The presence of dimethylsulfide (DMS) in those wines is implicated

Chinese localization of wine aroma descriptors

Wine aroma descriptors are important tools for wine evaluation. The present well-known wine aroma descriptor system was created and based on Western culture, which makes difficult for Chinese consumers to recognize and learn wine. AIM: The aim of this study was to update the wine aroma descriptor system for Chinese.

Methods: Fifty-four wine aroma descriptors of ‘Le nez du vin’ was used as substitution candidates. Firstly, a survey on unfamiliar aromas was distributed to 150 untrained Chinese wine consumers. Twenty attributors, such as blackcurrent buds, quince, linden, were selected as the most 17 unfamiliar. Then, a descriptive analysis was performed by trained tasting panel to substitute the targeted twenty aromas perfume. Furthermore, reference standards were looked and new le nez du vin were made. Finally, a substitution analysis was performed to replace the unknown wine aroma to the Chinese local aromas.

Characteristics of ecological production of grape and wine in Prizren’s vineyard territory in Yugoslavia

Prizren’s vineyard territory-y assigned for ecological production of grapes and wine includes 1. 200 hectares of vineyard located in five separate localities which belongs to the P KB “Kosovo vina”, Mala Krusa in Prizren. Division of vineyard territory in zones was carried out in 1974. Pertaining to the vineyards, the climate and soil conditions have been studied and determined as well as topographie establishing of vineyard boundaries.

Diffuse light due to wildfire smoke enhances gas exchange of shaded leaves

The risk of wildfires is increasing as the frequency and severity of drought and heat waves continue to rise. Wildfires are associated with the combustion of plant materials and emit smoke. In the atmosphere, smoke may spread readily across large areas. Smoke is composed of solid and liquid phase particulates and gases and has been identified as a causal agent of “smoke taint” in wine. On a smoky day, the intensity of direct light decreases because these particulates scatter sunlight. Even though this effect is frequently assumed to decrease plant photosynthesis, this assumption ignores the potential changes in diffuse light and may be based on scant evidence.

Characterization of vine vigor by ground based NDVI measurements

Many farming operations aim at controlling the leaf area of the vine according to its load. There are several techniques, direct and indirect, of estimate of this leaf area in a specific way, but impossible to implement at great scales. These last years, research in airborne and satellite remote sensing made it possible to show that a multispectral index of vegetation, computed from measurements of reflectances (red and near infrared), the « Normalised Difference Vegetation Index » (NDVI), is well correlated to the « Leaf Area Index » (leaf area per unit of ground) of the vine. Nevertheless these methods of acquisition and processing data are rather constraining and complex.
