Management of water status in vineyards: meta-analysis of its effects on yield and grape composition

Abstract

Context and purpose of the study: Mediterranean vineyards have been traditionally grown under rainfed conditions, but in recent decades the irrigated area has increased significantly, seeking to minimize the adverse effects of severe water stress on grape quality and yield. Given the large area occupied by vineyards, and the increasing scarcity of water resources, it is necessary to develop strategies for the optimization and efficient use of water to reduce the risk of its overexploitation. The present study aims at valorizing previous knowledge generated in different research projects by means of a meta-analysis of the effects of water status management on vineyard performance.

Material and methods: A database compiling around 1,400 replicates belonging to 41 water management trials conducted in Spain between 1996 and 2020, covering a wide range of soil and climatic conditions, was used. Each replicate was classified by its level of water stress as No Stress (>-0.411 MPa), Mild (-0.674 to -0.411 MPa), Moderate (-0.936 to -0.674 MPa), High (-1.2 to -0.936 MPa), and Severe (<-1.2 MPa), using their stem water potential values averaged over the season. The mean response ratios and the proportion of change produced by the increase in water stress on vegetative development, yield and grape composition were evaluated.

Results: Changes in plant water status caused significant differences in the parameters analyzed, regardless of the starting stress level, although these patterns varied depending on the specific parameter being analyzed. Thus, the change in pruning wood weight and yield with increasing stress ranged from -5% to -26%, with the greatest changes occurring from moderate to high stress. The changes in soluble solids content of berries ranged from +0.4% to +1.5% with increasing stress, except when increasing from moderate to high stress (-0.74%). In the case of titratable acidity, the change from increasing from a high level of stress to a severe one was +1.4%, while in all other cases it decreased (between -2.6% and -5.2%). The results showed the overall impact of plant water status management in the vineyard performance and constitute a valuable tool for the management of this resource.

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.
