What is the best soil for Sangiovese quality wine?

Abstract

Sangiovese is one of the main cultivar in the Italian ampelographic outline and it occupies more than 60% of total vineyard surface in the Tuscany region. It is also well known that the environmental variability causes an important influence over the viticultural and oenological results of Sangiovese, which does not have strict genetic control over the vegetal-productive behaviour.
The aim of this work was to single out the best soil characteristics for Sangiovese quality, on the basis of the vine performance of Sangiovese (VPS). For this purpose, a matching table, considering eight viticultural parameters, was utilized. The matching table permitted to classify the selected parameters into three classes of decreasing vine performance. A set of 79 experimental plots, sited on 47 farms, were utilized during a time span varying from two to five years (1989-1992; 1993-1994; 1997-2000; 2002-2007 and 2008-2009). Two datasets were created. One considering all the invariant soil and topography characteristics of the plots. The second, storing the year-depended variables. The data were submitted to principal component analysis (PCA) to highlight those invariant and year-depended climate and pedoclimate variables which were significantly correlated with the average values of the VPS of each vineyard. Discriminant Analysis was employed to identify the most significant variables and their discriminating power on VPS.
The results highlighted that invariant site characteristics are the most discriminant at the province level, while climate and pedoclimate show their influence on VPS at more detailed scales. At the province level, VPS is significantly influenced by rock fragments, stoniness, available water capacity (AWC), and elevation. The ideal soil for Sangiovese in the province of Siena is placed between 315 and 335 m asl, has an AWC ranging from 110 and 120 mm, shows a limited surficial stoniness of about 8-10%, and it is rather skeletal (rock fragments content 12-16%).
These results can be used in land evaluation and vine zoning, in particular, for the selection of the best crus of the province, they may help the choice of land for a new vine planting, but they might be also used in pedotechnique, that is, in the creation of vineyard soils by means of earth movements.

Mapping and tracking canopy size with VitiCanopy

Understanding vineyard variability to target management strategies, apply inputs efficiently and deliver consistent grape quality to the winery is essential. However, despite inherent vineyard variability, the majority are managed as if they are uniform. VitiCanopy is a simple, grower-friendly tool for precision/digital viticulture that allows users to collect and interpret objective spatial information about vineyard performance. After four years of field and market research, an upgraded VitiCanopy has been created to achieve a more streamlined, technology-assisted vine monitoring tool that provides users with a set of superior new features, which could significantly improve the way users monitor their grapevines. These new features include:
• New user interface
• User authentication
• Batch analysis of multiple images
• Ease the learning curve through enhanced help features
• Reporting via the creation of colour maps that will allow users to assess the spatial differences in canopies within a vineyard.
Use-case examples are presented to demonstrate the quantification and mapping of vineyard variability through objective canopy measurements, ground-truthing of remotely sensed measurements, monitoring of crop conditions, implementation of disease and water management decisions as well as creating a history of each site to forecast quality. This intelligent tool allows users to manage grapevines and make informed management choices to achieve the desired production targets and remain profitable.

Bees, climate changes, and “environmental sustainability 4.1c” in viticulture and the territory for a new global multiproductive “biometaethical district 4.1c”

The use of bees as pollinators in vine varieties with physiologically female flowers (Picolit, Bicane, Ceresa, Moscato rosa, etc.) (Cargnello, 1983) and as bio-indicators for biodiversity and environmental sustainability is well-known. Furthermore, there are interests in: 1-a. Making the viticulture of Belluno (Province of Veneto in North-eastern Italy, which is also famous for the Dolomites -a UNESCO World Heritage-) regain the socioeconomic role which it is entitled to and which it had got in its past by aiming at the enhancement of local grape variety in harmony with others, for example with the neighboring area of the Conegliano and Valdobbiadene Prosecco Superiore DOCG; 2-a. Maintaining and further improving the important natural and healthy environment of Belluno, and making its territory and the “lookout” means of the environmental sustainability, including its vineyards, even more naturally original and sustainable 4.1C.

A DNA-free editing approach to help viticulture sustainability: dual editing of DMR6-1 and DMR6-2 enhances resistance to downy mildew 

The sustainability of viticulture hinges on maintaining quality and yield while reducing pesticide use. Promising strides in this direction involve the development of clones with enhanced disease tolerance, particularly through the knockout of plant susceptibility genes. Knocking out of Downy Mildew Resistant 6 (DMR6) led to increased levels of endogenous salicylic acid (SA), a regulator of immunity, resulting in enhanced tolerance to Downy Mildew (DM) and other diseases in various crops.

Enhancing grapevine transformation and regeneration: A novel approach using developmental regulators and BeYDV-mediated expression

Grapevine (Vitis vinifera L.) is a challenging plant species to transform and regenerate due to its complex genome and biological characteristics. This limits the development of cisgenic and gene-edited varieties. One hurdle is selecting the best starting tissue for the transformation process, much like isolating suitable tissue for protoplasts. One promising method involves delivering crispr/cas components to protoplasts isolated from embryogenic calli, which are then induced to regenerate.
