Re-examination and meta-analysis of previous research as a tool to evaluate the suitability of rootstocks in adaptation to global change. A study case from Spanish viticulture


Meta-analysis (MA) is a method that allows statistical synthesis of the results of several similar individual studies (Figure 1). This term was introduced by Glass in 1976 as a useful tool for the scientific community to pool and summarise the enormous amount of information collected in the literature (Glass, 1976).  However, the MA is not only used to quantify the results obtained from different trials, but also allows to Identify characteristics of the different trials where the variability of the results lies, Identify possible areas for future research focus and, present new hypotheses in response to conflicting results

Agronomy, like any other science, has the same need to compile the enormous amount of data and information collected in research work. For this reason, the MA is a methodology of great interest for this science, and researchers are making increasing use of it. If we analyse the use of this tool by consulting the Scopus database on the number of articles in the field of agronomy that use this word (“meta-analysis”) in their title or abstract, we can see how, over the years, there has been an exponential increase in their use, nearly no records in the 1990s, around 50 articles per year in the early 2000s, raising up to 250 articles per year in the early 2010s, and currently reaching  750 articles per year. In the case of viticulture, there are already some relevant meta-analysis have also been performed (Payen et al., 2021; Santesteban et al., 2019; Winter et al., 2018), and their informativeness is undeniable.

In a context where viticulture is facing emerging challenges, not only due to the effect of climate change on grape yield and composition, but also due to the social demand for environmental-friendly agricultural management, rootstocks have been already identified as key players to face these challenges (Marín et al., 2020). Therefore, there is a need to re-examine previous works to anticipate which can be the behaviour expected for each rootstock in this changing environment, particularly considering that rootstock performance can only be evaluated after time and space consuming experiments, and that any decision made when establishing a vineyard will condition grape and wine characteristics throughout its entire lifetime. The statistical analysis of the results of previous scientific studies (i.e., a meta-analysis) can be a complementary tool to new field experiments to evaluate rootstock suitability to new conditions.

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.
