Effect of soil particle size on vine water status, leaf ABA content and berry quality in Nebbiolo grapes

Abstract

The root and shoot abscisic acid (ABA) accumulation in response to water deficit and its relation with stomatal conductance is longtime known in grapevine. ABA-dependent and ABA-independent signalling response to osmotic stress coexist in sessile plants. In grapevine, the signaling role of ABA in response to water stress conditions and its influence on berry quality is critical to manage grapevine acclimation to climate change. The prevalent iso- or aniso-hydric behavior of grapevine varieties can be mitigated by the soil draining capacity: in the anisohydric Syrah grown in pots and in controlled conditions, an ABA-related stomatal closure was induced in water-retaining soils, resulting in a superimposition of the soil-related hormonal root-to-shoot signal respect to the putative genotypic-induced anisohydric response to water stress. In two consecutive years (2012 and 2013) we analyzed Nebbiolo water relations in two rain-fed vineyards (distance as the crow flies between the two was about 250 m) located on the Cannubi hill (Barolo area, Langhe Wine District, Piedmont, Italy). Vines were grafted on Vitis berlandieri x V. riparia rootstocks and soil were classified (USDA) as silty-loam (with 18 % of clay) and as loam (13 % of clay). We measured stomatal conductance, stem water potential, ABA leaf content and the main berry quality parameters. In 2013, the vineyard management (winter and green pruning, and bunch balance according to ‘Yield to Pruning Weight’ and ‘Leaf Area to Crop Weight’ ratios) allowed to avoid any discrepancies in the two vineyards vegetative-productive balance. Data showed that when drought was prolonged, Nebbiolo reduced its anisohydricity acting drought-induced stomatal closures earlier and for a longer period in the silty-loam soil, (richer in clay and more compact), respect to the loamy soil. The silty-loam soil determined a higher leaf ABA content during the season. This fact could explain the improved qualitative traits of berries harvested in the vineyard in the 18% clayey soil such as a higher content of anthocyanins (mg/berry), with a higher level of acylation (increase of color stabilization) and a higher content of free terpenes, following ABA-triggered metabolite responses.

Effects of different soil types and soil management on greenhouse gas emissions 

Soil is important in the carbon cycle and the dynamics of greenhouse gases (CO2, CH4 and N2O). Key soil characteristics, such as organic matter content, texture, structure, pH and microbial activity, play a determining role in GHG emissions[1]. The objective of the study is to delimit different types of soil, with different soil management and to be able to verify the differences in CO2, CH4 and N2O emissions. The study was carried out in a vineyard of Bodegas Campo Viejo in Logroño (La Rioja), whose plant material is Vitis vinifera L. cv. Tempranillo.

Physico-chemical properties of vine pruning residues with potential as enological additive

Grapes are one of the world’s primary fruit crops, and pruning activities generate high amounts of annual wood wastes [1]. These pruning shoots contain valuable phenolic compounds and could have numerous potential applications [1,2]. Consequently, the aim of this work was to evaluate the physico-chemical properties of vine pruning residues with potential as enological additives. For this purpose, grapevine shoots from 12 varieties grown in Chile were collected during the winter of 2021.

Detoxification capacities of heavy metals and pesticides by yeasts 

Winegrowing is still characterized by the extensive use of chemical fertilizers and plant protection products, despite strong recommendations to limit these practices. A part of these xenobiotics and metals are then found in grape juice and wine, causing a major health concern, as well as negatively affecting the fermentation process. In recent years, there has been renewed interest in non-Saccharomyces yeasts. These species have a wide phenotypic diversity, which would be exploited to broaden the aromatic palette of wines.

How are canned wine drinkers perceived? An investigation involving Swiss nationals and different scenarios of outdoor leisure activities

This study examines how people who consume wine in cans are perceived in terms of their basic personality characteristics, helps understand the role of cultural background on people’s perception, and verify the role played by the consumption context on the perception. Our hypothesis is that prejudice and negative attitudes towards wine in cans might exert a negative effect on the evaluation of people who consume canned wine. To evaluate this hypothesis, the consumption of wine in cans was evoked in four different contexts of use during outdoor leisure activity (beach resort, ski resort, desert safari, and party). In order to examine the effect of culture on subject’s response we use participants from Switzerland, a country where three different cultures, associated with three different languages, cohabit.
