Zoning influence in chromatic parameters in Monastrell grape

Abstract

Zoning analysis determine homogeneous areas principally from the point of view of the medium, giving as a result a map which cartographic units synthesize the relations between the edaphic factors; morphological factors of the soil and climatic factors. The combination of these types of parameters allows to obtain maps of suitability of the optimum areas for the crop of the vineyard. At present it has been delimited and characterized eight grape areas belonging to the D.O. Jumilla. The chosen plots has been: Varahonda, Cañada del Judío, Cañada de Albatana, El Carche, Rubializas, Agüeros, Cortijo del Agrio and Casa Vistalegre. 
The determined parameters are: Phenological parameters: Dates of sprouting, flowering, veraison, and harvest. Chemical parameters during maturation: total phenolic compounds, anthocyanins to pH 1 (extractable anthoc.) and anthocyanins to pH 3 (Total anthoc.), seed ripeness (MP) and index of cellular ripeness (IMC). 
As for the determination of chromatic parameters and of extractability, in the plot of Cortijo del agrio the biggest quantity of anthocyanins has been obtained on having finished the period of ripening, on the other hand the plot of Cañada del Judio is the one that has obtained the highest values of extractable polyphenols. In our study, for the IMC lower value has been obtained for the plot located in Cañada del Judio and the highest value for the plot of Cortijo del agrio. As for seed ripeness Rubializas and Cortijo del agrio are the plots that obtained the lowest values.

Beneficial effects of moderate consumption of Teran red wine on blood lipid profile: a preliminary study on healthy volunteers

Moderate wine consumption may impact several human health aspects, among others as a result of phenolic compounds present in wine and their bioactive properties. The aim of this study was to determine whether six weeks of daily, moderate Teran red wine consumption affects the levels of total cholesterol, high-density lipoprotein cholesterol – HDL, low-density lipoprotein cholesterol – LDL, and triglycerides. Sixty-eight healthy adults (46 women and 22 men) aged 25-64 years voluntarily agreed to participate in the study.

Can soil water content be used as a predictor of predawn leaf water potential for deficit irrigation scheduling? A case study at Alentejo wine region

Water and heat stress impose new challenges to irrigation management in the Mediterranean areas. This reality has a major impact on the vineyard ecosystem, particularly on the scarce water resources of the Alentejo region (South Portugal). To mitigate this problem, irrigation management should focus on optimizing yield and fruit quality per volume of water applied. This work aims to discuss the use of predawn leaf water potential and soil water status relationships as a decision tool for irrigation management taking as basis data from a field trial where two deficit irrigation strategies were compared.

Grapevine vigour is correlated with N-mineralization potential of soil from selected cool climate vineyards in Victoria, Australia

Excess vigour has been a problem on fertile soils under high rainfall in many cool climate regions of Australia. High and low vigour blocks were selected in vineyards of the cool climate regions of King Valley, Yarra Valley and Mornington Peninsula, Victoria.
