New insights into Early Celtic consumption practices: Organic residue analyses of local and imported pottery from Vix-Mont Lassois
2019
The rich Mediterranean imports found in Early Celtic princely sites (7th-5th cent. BC) in Southwestern Germany, Switzerland and Eastern France have long been the focus of archaeological and public interest. Consumption practices, particularly in the context of feasting, played a major role in Early Celtic life and imported ceramic vessels have consequently been interpreted as an attempt by the elite to imitate Mediterranean wine feasting. Here we present the first scientific study carried out to elucidate the use of Mediterranean imports in Early Celtic Central Europe and their local ceramic counterparts through organic residue analyses of 99 vessels from Vix-Mont Lassois, a key Early Celti…
Fruit yield and quality responses of apple cvars Gala and Fuji to partial rootzone drying under Mediterranean conditions
2012
SUMMARYIncreasing irrigation efficiency is a major goal for fruit production in dry Mediterranean environments. The present study was conducted in three consecutive years (2007–09) under typical Mediterranean conditions and tested the effect of partial rootzone drying (PRD) on yield and fruit quality of two apple cultivars: Gala, with fruit maturing in summer and Fuji, with fruit maturing in autumn. Three irrigation treatments were imposed: conventional irrigation (CI), PRD (0·50 of CI water on one side of the rootzone, which was alternated periodically) and continuous deficit irrigation (DI, 0·50 of CI water on both sides of the rootzone). During the 2008 and 2009 irrigation seasons, DI re…
The Emergence of Arboriculture in the 1st Millennium BC along the Mediterranean’s “Far West”
2021
This paper presents the history of the introduction and expansion of arboriculture during the 1st millennium BC from the South of the Iberian Peninsula to the South of France. The earliest evidence of arboriculture at the beginning of the 1st millennium hails from the south of the Iberia from where it spread northward along the peninsula’s eastern edge. The different fruits (grape, olive, fig, almond, pomegranate and apple/pear) arrived together in certain areas in spite of uneven distribution and acceptance by local communities. Grape was the crop with the greatest diffusion. The greater diversity of crops in the southern half of the peninsula is also noteworthy. Their development paved th…
Conservation tillage in a semiarid Mediterranean environment: results of 20 years of research
2014
Conservation tillage techniques are becoming increasingly popular worldwide as they have the potential to generate environmental, agronomic, and economic benefits. In Mediterranean areas, studies performed on the effects of conservation tillage [in comparison with the conventional tillage technique (CT)] on grain yield of cereal crops have reported contradictory results as well as considerable year-to-year variation, demonstrating how the impact of different soil tillage techniques on crop productivity is strongly site-specific. The present paper summarises the main results from a set of experiments carried out in Sicily during the last 20 years in which we compared no tillage (NT) to CT in…
EFFECT OF CULTIVAR AND CROWN SIZE ON YIELD AND QUALITY OF STRAWBERRY FRESH BARE ROOT PLANTS IN SICILY
2012
In the southern regions of Mediterranean areas the plantations with fresh plants (winter planting system) have almost completely replaced those with cold stored plants (summer planting system). Particularly, fresh bare root plants produced in high elevation nurseries located in Spain and Poland and, in experimental phase, in the southern of Italy (in the mountains of Sicily, Calabria, Basilicata) are the most used. Such type of plant usually has a crown diameter from 6 to 14 mm, but the smallest plants should be (<8 mm) discarded in phase of selection and packing. Objective of this study was to investigate the influence of the different crown diameter on the earliness, productivity and qual…
The impact of moderate wine consumption on health
2014
Wine is a traditional beverage that has been associated with both healthy and harmful effects. Conceptions like the so-called "French paradox" or the beneficial impact of the Mediterranean diet suggest benefit. Wine has a complex composition, which is affected by whether it is red or white or by other variables, like the variety of grapes or others. Alcohol and phenolic compounds have been attributed a participation in the benefits ascribed to wine. The case of alcohol has been extensively studied, but the key question is whether wine offers additional benefits. Resveratrol, a non-flavonoid compound, and quercetin, a flavonol, have received particular attention. There is much experimental w…
Urinary Tartaric Acid, a Biomarker of Wine Intake, Correlates with Lower Total and LDL Cholesterol.
2021
Postmenopausal women are at higher risk of developing cardiovascular diseases due to changes in lipid profile and body fat, among others. The aim of this study was to evaluate the association of urinary tartaric acid, a biomarker of wine consumption, with anthropometric (weight, waist circumference, body mass index (BMI), and waist-to-height ratio), blood pressure, and biochemical variables (blood glucose and lipid profile) that may be affected during the menopausal transition. This sub-study of the PREDIMED (Prevención con Dieta Mediterránea) trial included a sample of 230 women aged 60–80 years with high cardiovascular risk at baseline. Urine samples were diluted and filtered, and tartari…
Identification of a 49-kDa hydrophobic cell wall mannoprotein present in velum yeast which may be implicated in velum formation
2000
Analysis of velum-forming yeast cell wall components released by beta-1,3-glucanase treatment were compared with those of a non velum-forming yeast. SDS-PAGE electrophoresis and Western blotting with ConA-peroxidase staining of mannoproteins allowed us to identify a 49-kDa mannoprotein present in the cell wall of the velum-forming yeast and hardly visible in the control. The cell wall nature of this protein was confirmed by labelling with the non-permeable sulfosuccinimydiyl-6-(biotinamido)hexanoate reagent. A partial purification of this mannoprotein by anion exchange HPLC followed by surface hydrophobicity determination revealed that the fraction containing the 49-kDa mannoprotein was the…
Influence des facteurs naturels sur la maturation du raisin, en 1979, à Pomerol et Saint-Emilion
1981
<p style="text-align: justify;">Les vignobles de Pomerol et Saint-Emilion sont implantés sur des sols dérivant de roches-mères variées; ils produisent des vins de haute qualité mais différents suivant leur origine géologique.</p><p style="text-align: justify;">Dans les meilleurs crus, nous avons pu vérifier que les variations mésoclimatiques sont très faibles et ont peu d'influence sur les caractères des vins. Par contre, en 1979, une relation a été mise en évidence entre les conditions de l'alimentation en eau de la vigne (étroitement liées aux propriétés physiques des sols) et la constitution des raisins à maturité (<em>V. vinifera</em> var. Merlot noir).<…
