Application of organic carbon status indicators on vineyard soils: the case study of DOC Piave (Veneto region, Italy)

Abstract

According to the Kyoto Protocol objectives, it’s necessary to identify alternative carbon dioxide sinks, and vineyard soils could be a significant opportunity. A set of soil organic carbon status indicators, proposed by JRC (Stolbovoy, 2006), was tested on vineyard soils of DOC Piave area (Veneto region) to validate it. Information available in the regional soil database for the study area (Soil Maps of Treviso and Venice provinces at 1:50,000 scale with 614 soil profiles on about 150,000 ha, 5% of which with vineyards) was analysed to point out significant relationships between soil organic carbon content, soil type and land uses. An approach for functional soil groups was adopted: the soil typological units were grouped on the basis of texture, coarse fragments, drainage and physiography (Manni, 2007). The highest value, which differs statistically from the others, was observed in fine texture and poorly drained soils. Furthermore, vineyard soils showed higher content than crop soils, especially on the first 30 cm. But no significant differences were observed. Then, for each functional group and separately for vineyard and crop topsoil and subsoil, a set of soil organic carbon status indicators were defined. The results showed higher capacity to sequestrate carbon on vineyard topsoil. The present study allows an overview of the DOC Piave area carbon pool and highlights priorities areas where policy interventions should be concentrated.

EFFECT OF FUMARIC ACID ON SPONTANEOUS FERMENTATION IN GRAPE MUST

Malolactic fermentation (MLF)¹, the decarboxylation of L-malic acid into L-lactic acid, is performed by lactic acid bacteria (LAB). MLF has a deacidifying effect that may compromise freshness or microbiological stability in wines² and can be inhibited by fumaric acid [E297] (FA). In wine, can be added at a maximum allowable dose of 0.6 g/L³. Its inhibition with FA is being studied as an alternative strategy to minimize added doses of SO₂⁴. In addition, wine yeasts are capable of metabolizing and storing small amounts of FA and during alcoholic fermentation (AF).

Lipids at the crossroads of protection: lipid signalling in grapevine defence mechanisms

Understanding grapevine molecular processes and the underlying defence responses is vital for developing sustainable disease control strategies. Lipid signalling pathways, involving the synthesis and degradation of lipid molecules, have emerged as a key regulator in plant defence against pathogens. This study aims to elucidate the role of fatty acids and lipid signalling in grapevine’s defence response to P. viticola infection. The expression of lipid metabolism-related as well as lipid signalling genes was analysed, by qPCR, in three grapevine genotypes: Chardonnay (susceptible), Regent (tolerant) with Rpv3-1 resistance loci, and Sauvignac (resistant) harbouring a pyramid of Rpv12 and Rpv3-1 resistance loci.

Closure permeability: a key parameter for modulating the aroma of monovarietal white wines during bottle ageing

Bottle aging is crucial for wine quality, influencing its chemical and sensory properties [1]. Ideally, a phase of qualitative ageing enhances sensory attributes before a decline in quality occurs. Understanding the impact of oenological variables on these phases is a key challenge in modern winemaking.

Evaluation of intra-vineyard spatial and temporal variability of leaf area index using multispectral images obtained by satellite (Landsat 8, Sentinel-2) and unmanned aerial vehicle platforms

Estimation of vineyard leaf area index (LAI) is an important aspect for the winegrowers. However, tracking and monitoring are difficult tasks due to time constraints. Satellite and unmanned aerial vehicle (UAV) imaging have become a practical monitoring method for LAI. Nevertheless, for a proper LAI determination, the image’s spatial resolution is a key factor, since low-resolution images are incapable of distinguishing between adjacent vines due to the large area covered in each pixel, this leads to misinterpretation or generalisation of vineyard information.
