Zonificación climática de las D.O. Rueda y Toro y vinos de la tierra de medina del campo

Abstract

La producción vitícola es el resultado de una serie de factores influyentes (variedad, patron) dentro de un medio ecológico­-climatico-edafico, en el que se interactua por medio de técnicas de cultivo adecuadas.
En la caracterización climática del viñedo estan presentes tanto los elementos tradicionales (temperatura, precipitación, insolación, etc.) así como los factores geográficos (latitud y longitud, altitud, orientación, exposición, proximidad a masas de agua, etc).
Para ver la influencia sobre el vinedo, en las distintas fases de su ciclo vegetativo, se cuantifican y se analizan los parametros mas relevantes en las D.O. Rueda y Toro, Tierra de Vinos.
Las caracteristicas climáticas más destacables de la región pueden ser resumidas (Garcia Femandez, 1986) como sigue:
– clima continental determinado por los efectos de encajamiento y aislamiento definidos por las cadenas montañosas que la rodean.
– rigurosos ( crudos) y largos inviemos: bajas temperaturas medias y generalización de los val ores negativos de las temperaturas medias de las minimas del mes de enero, minimas absolutas acusadamente bajas y largo periodo invernal.
– veranos cortos, relativamente suaves y con fuertes oscilaciones térmicas, con periodos estivales fríos y otros de calor riguroso.
– contrastes acusados en la cuantía y bajos indices de precipitaciones.
– aridez estival sensible y contrastada: acusada aridez estival, complejidad de la precipitación estival, duración de la aridez estival.
– régimen de precipitaciones con contrastes y matices con predominio de la de invierno y primavera.

Effect of mixed Torulaspora delbrueckii-Saccharomyces cerevisiae culture on rose quality wine

Alcoholic fermentation using no Saccharomyces wine is an effective means of modulating wine aroma. This study investigated the impact of coinoculating Torulaspora delbruecki with two Saccharomyces cerevisiae commercial yeast (QA23, Lallemand; Red Fruit, Sepsa-Enartis) on enological quality parameters, volatile composition and sensory analysis. The following assays were performed on Tempranillo variety: Saccharomyces QA23 (CTQA), Saccharomyces Red Fruit (CTRF), coinoculated T. delbrueckii + S.cerevisiae QA23 (CIQA) and coinoculated T. delbrueckii + S.cerevisiae (CIRF).

Mycorrhizal symbiosis modulates flavonoid and amino acid profiles in grapes of Tempranillo and Cabernet Sauvignon 

Arbuscular mycorrhizal fungi (AMF) symbiosis is probably the most widespread beneficial interaction between plants and microorganisms. AMF has been widely reported to promote grapevine growth, water and nutrient uptake as well as both biotic and abiotic stress tolerance[1]. However, the impact of AMF on grape composition has been less studied. The aim of this work was to evaluate the effects of the association between two commercial grapevine cultivars (Tempranillo and Cabernet Sauvignon grafted onto 110 rootstock) and AMF on the anthocyanin, flavonol and amino acid concentrations and profiles of grapes.

Nitrogen requirements of table grape cultivars grown in the san Joaquin valley of California

Ground water in the interior valleys of California is contaminated with nitrates derived from agricultural activities, primarily the over-fertilization of crops.

Spectral characterisation of fungal diseases on Vitis vinifera leaves

Aims: The aims of this study were to (1) detect alterations in the reflectance spectra of vines with fungal diseases, (2) map these alterations, and (3) determine the best wavelengths which may be used as early indicators of fungal diseases in vines.

Uncovering the effectiveness of vineyard techniques used to delay ripening through meta-analysis

One of the most concerning trends associated with increasing heat and water stress is advanced ripening of grapes, which leads to harvesting fruit at higher sugar concentrations but lacking optimal phenolic (i.e. color and mouthfeel) and aromatic maturity. Mitigation techniques for this phenomenon have been studied for many years and practices to delay sugar accumulation have been identified, including antitranspirants, delayed pruning and late-source-limitation techniques. Evaluation of the efficacy of these vineyard practices has occurred across a wide range of environments, vintages, varieties and growing conditions. To assess the broader efficacy of these three vineyard practices, which are easy-to-implement and cost-effective, a meta-analytic approach was adopted using data retrieved from 43 original studies.
