Response of Albariño to local environmental conditions in Uruguay


Context and purpose of the study

Albariño is a white cultivar that has been recently promoted in Uruguay due to its ability to maintain high berry quality even in adverse climate conditions during ripening. This study aims to assess the effect of different topographic conditions on Albariño agronomic behavior and oenological potential.

Material and methods

Ten Albariño plots located at different aspects of exposure, altitude and slope were selected in the emerging wine-growing region of Eastern Uruguay. To assess spatial temperature variability due to the topography conditions, a temperature sensor was installed in each plot. Bioindicators for grapevine were calculated, and relationships between site topography and plant responses (yield components and berry composition) were analyzed using climatic and agronomic data recorded over three seasons (2019, 2020, and 2021).


In the plots of Albariño under study, we found that the interactions between topography and berry metabolites varied through the seasons. The slope was the topography factor which showed a more substantial impact on local temperature and berry metabolites. Plots on steeper slopes (8.8 to 11.6º) favored grapes with a higher acid content (more than 0.43 gH2SO4 per liter), while plots at lower elevations provided berries with higher amounts of secondary metabolites (more than 1.6 units of phenol richness). No significant statistical relationships were found between yield, local climate, and topography. This cultivar showed less differences in berry composition associated with temporal and spatial climate variability due to topography than other cultivars like Tannat (red cultivar).

Effect of foliar application of Ca, Si and their combination on grape volatile composition

Calcium (Ca) is an important nutrient for plants which plays key signaling and structural roles. It has been observed that exogenous Ca application favors the pectin accumulation and inhibition of polygalacturonase enzymes, minimizing fruit spoilage. Silicon (Si) is a non-essential element which has been found to be beneficial for improving crop yield and quality, as well as plant tolerance to diverse abiotic and biotic stress factors. The effect of Si supply to grapevine has been assessed in few investigations, which reported positive changes in grape quality and must composition.

Late winter pruning induces a maturity delay under temperature-increased conditions in cv. Merlot from Chile

Chile is considered vulnerable to climate change; and these phenomena affect several mechanisms in the grape physiology and quality. The global temperature increase affects sugar contents, organic acids, and phenolic compounds in grapes, producing an imbalance maturity. In this sense, an alternative to reduce the impact is to perform pruning after vine budburst, known as “Late Pruning” (LP).

Effect of two water deficit regimes on the agronomic response of 12 grapevine varieties cultivated in a semi-arid climate

The Mediterranean basin is one of the most vulnerable regions to Climate Change effects. According to unanimous forecasts, the vineyards of Castilla-La Mancha will be among the most adversely affected by rising temperatures and water scarcity during the vine’s vegetative period. One potential strategy to mitigate the negative impacts of these changes involves the identification of grapevine varieties with superior water use efficiency, while ensuring satisfactory yields and grape quality.

Influence of irrigation frequency on berry phenolic composition of red grape varieties cultivated in four spanish wine-growing regions

The global warming phenomenon involves the frequency of extreme meteorological events accompanied by a change in rainfall distribution. Irrigation frequency (IF) affects the spatial and temporal soil water distribution but its effects on the phenolic composition of the grape have been scarcely studied. The aim of this work was to evaluate the effects of four deficit irrigation frequencies of 30 % ETo: one irrigation per day (T01), two irrigations per week (T03), one irrigation per week (T07) and one irrigation every two weeks (T15) on berry phenolic composition at harvest.

Response of red grape varieties irrigated during the summer to water availability at the end of winter in four Spanish wine-growing regions: berry phenolic composition

Water availability is the most limiting factor for vineyard productivity under Mediterranean conditions. Due to the effects caused by the current climate change, wine-growing regions may face serious soil moisture conservation problems, due to the lower water retention capacity of the soil and higher soil irradiation. The aim of this work was to evaluate the effects of soil recharge irrigation in pre-sprouting and summer irrigation every week (30 % ETo) from the pea size state until the end of ripening (RP) compared to exclusively summer irrigation every week (R) in the same way that RP, on berry phenolic composition at harvest.
