Influence of the irrigation period in Tempranillo grapevine, under the edaphoclimatic conditions of the Duero river valley


Irrigation of vineyards is a matter of controversial arguments at areas of high quality wine production. Besides, the effects of the water in the plant are closer related to the water availability than to the irrigation regime. In this way, the criteria for irrigation timing can reach very important physiologic and productive consequences to optimize the vineyard management on each environmental situation. An experimental trial has been carried out along the period 2005-2007 in the province of Valladolid (Spain), focused on the study of modification of plant water status (leaf water potential), soil water content, physiologic activity, vegetative-productive behavior and quality expression (berry weight, sugar concentration, pH, total acidity, poliphenols concentration) of the Tempranillo variety in the Duero river valley, through the application of a moderate irrigation doses in two different periods of the vegetative cycle, on a concrete edaphic situation. The treatments applied were the following: 20% ETo from vegetative Growth stopping (G20) and 20% ETo from Veraison (V20), both irrigated until one week before harvest. The vines, planted in 1993, were grafted onto 110R and vertical trellised trained, as a bilateral Royat cordon. Vine spacing is 2.70 m x 1.40 m (2645 vines/ha).
The results have shown some differences due to the irrigation period treatments on the effects related to vine water status and soil water content, physiologic activity, vegetative development, productivity and grape quality in Tempranillo variety. In general, the earlier application of irrigation has favoured vine physiologic activity and leaf development, through the improvement of plant water status, estimated by means of leaf water potential measurement, which have consequently provoked certain increase of yield. On the contrary, the delay of irrigation until veraison stage has shown certain tendency in grape composition to increase sugar concentration, pH and poliphenols index.

Soils and plant material in prestigious Bordeaux vineyards impacts on yield and quality

High resolution soil maps (scale : 1/3000) were created for seven of the most prestigious red wine producing estates in Bordeaux, covering in total approximately 400 ha.

Carbon isotope ratio (Δ13C) and phenolic profile used to discriminate wines from Dealu mare and Cotnari regions (Romania)

Regarding the food quality, authenticity is one of the most important issues in the context of ensuring the safety and security of consumers, but is also more important when it comes to wine (one of the most counterfeited foods in the world).

Relative impact of crop size and leaf removal on aromatic compounds and phenolic acids of Istrian Malvasia wine

Although several studies investigated the impact of crop size or fruit zone microclimate on aromatic or phenolic composition of wines, the effects of these two practices were not assessed and compared in the same study through a technological experiment within the same vineyard. Therefore, their relative effectiveness is hard to compare, which in turn is essential for providing producers with valuable information as a basis to choose adequate approach in yield and canopy management. The aim of the study was to investigate the effects of two crop sizes and two different fruit zone microclimate conditions obtained by leaf removal in a two-factorial experiment, in order to assess and compare their relative impact on Istrian Malvasia (Vitis vinifera L.) white wine aroma and phenolic composition.

Soil, vine, climate change – what is observed – what is expected

To evaluate the current and future impact of climate change on Viticulture requires an integrated view on a complex interacting system within the soil-plant-atmospheric continuum under continuous change. Aside of the globally observed increase in temperature in basically all viticulture regions for at least four decades, we observe several clear trends at the regional level in the ratio of precipitation to potential evapotranspiration. Additionally the recently published 6th assessment report of the IPCC (The physical science basis) shows case-dependent further expected shifts in climate patterns which will have substantial impacts on the way we will conduct viticulture in the decades to come.
Looking beyond climate developments, we observe rising temperatures in the upper soil layers which will have an impact on the distribution of microbial populations, the decay rate of organic matter or the storage capacity for carbon, thus affecting the emission of greenhouse gases (GHGs) and the viscosity of water in the soil-plant pathway, altering the transport of water. If the upper soil layers dry out faster due to less rainfall and/or increased evapotranspiration driven by higher temperatures, the spectral reflection properties of bare soil change and the transport of latent heat into the fruiting zone is increased putting a higher temperature load on the fruit. Interactions between micro-organisms in the rhizosphere and the grapevine root system are poorly understood but respond to environmental factors (such as increased soil temperatures) and the plant material (rootstock for instance), respectively the cultivation system (for example bio-organic versus conventional). This adds to an extremely complex system to manage in terms of increased resilience, adaptation to and even mitigation of climate change. Nevertheless, taken as a whole, effects on the individual expressions of wines with a given origin, seem highly likely to become more apparent.

Comparison of the effects of hormone- and natural-based elicitors on key metabolic pathways in cv. Tempranillo

One of the most important effects of climate change in wine-growing areas is the advance of phenological stages, especially concerning early berry ripening. In the hottest seasons, this results in a lack of synchrony between sugar and phenolic ripeness. In order to cope with this fact, a general effort is being made by researchers and growers aiming at delaying ripening through different strategies. One of the proposed approaches is the application of elicitors. This study aims to assess the effect at the transcriptomic level of application of three elicitors (Vitalfit, Fruitel, and Protone) in Tempranillo.
