Zonazione aziendale nel territorio del Chianti classico e valorizzazione dei vini

Abstract

[English version below]

Nell’ambiente del Chianti Classico è stato applicato un progetto di zonazione aziendale con l’objettivo di valorizzare le produzioni dei diversi vigneti. In particolare sono stati individuati sette siti, sottoposti a studio particolareggiato per un triennio.
I parametri ecopedologici sono stati correlati ai dati fenologici e produttivi, con particolare riguardo alle sostanze coloranti. I vini ottenuti nelle varie tesi sono stati sottoposti ad analisi sensoriale allo scopo di valutare le potenzialità dei vitigno Sangiovese seconda diverse tecni­che di vinificazione, sia in legno che in acciaio.
I risultati sottolineano la variabilità fenotipica del Sangiovese, in relazione alla struttura fisica dei suoli esaminati. In particolare l’accumulo degli zuccheri risulta dipendere dalle caratteristiche del suolo, mentre il contenuto acidico risulta maggiormente influenzato dal­l’annata. ln condizioni climatiche simili i migliori risultati sono stati ottenuti in suoli ricchi di scheletro e terra fine, con buon drenaggio. La tecnica di maturazione del vino ha diversa­mente influenzato i prodotti ottenuti nei vari vigneti.

On a large farm in the Chianti Classico area, seven vineyards were studied. They had different levels of productivity despite similar cultural practices. The different vineyards were studied over a three-year period with regard to environmental and pedological aspects.
The parameters obtained have been correlated to phenological and productive trends, with regard to the sensorial analisys of wine and the color components. The wines were matured in oak barrel and steel tank to point out the best enological use of the different vineyards productions.
The results underline the phenotypical variability of Sangiovese, especialiy due to the physical structure of the examined soils. In particular, sugar accumulation depended on the soil characteristic, white acidity depended on the year. Under similar climate conditions, the best results on wine were obtained in sandy soils originating from sandy limestone rich with rock fragment. Maturation technique, using oak barrels or steel tanks, has differently influenced wines obtained from various soils.

A comprehensive study on the effect of foliar mineral treatments on grapevine microbiota, flavonoid gene expression, and berry composition

Recently, foliar treatments with mineral-based compounds have shown positive effects on grapevine production by protecting grape from thermal excesses and reducing the decoupling between technological and phenolic maturity caused by climate change. Unraveling the effect of mineral particle applications on grape-associated microbes is pivotal for successful wine processing, due to the influence of the microbiota on wine composition and stability. To our knowledge, this is the first work that comprehensively studied the effects of kaolin and chabasite-rich zeolitites treatments on grape-related microorganisms (by real-time PCR quantification of total fungi, Hanseniospora uvarum, Metschnikowia pulcherrima, plant-associated bacteria and lactic acid bacteria), the expression of genes related to the flavonoid biosynthesis (PAL1, CHS1, F3H2, DFR, LDOX, UFGT, MYBA1, GST4, FLS4 genes) and the berry composition (°Brix, pH, acidity and anthocyanin concentrations) in cv. Sangiovese during ripening in two growing seasons (2019 and 2020).

Functional characterization of grapevine MLO genes to define their roles in Powdery mildew susceptibility by CRISPR/Cas9 genome editing

Successful powdery mildew (PM) infection in plants relies on Mildew Resistance Locus O (MLO) genes, which encode susceptibility factors essential for fungal penetration. In Arabidopsis, loss-of-function mutations in three clade-V MLOs, AtMLO2, 6, and 12 confer complete resistance to PM infection. Since then, efforts are on to discover MLO genes contributing to PM susceptibility in many species to introduce mlo-based PM-resistance. Earlier studies in tomato and grapevine, using the RNAi approach, attributed PM susceptibility to SlMLO1, 5, and 8 and VvMLO3, 13, and 17, respectively indicating likely functional redundancy among MLOs.

Implementation of a deep learning-based approach for detecting and localising automatically grapevine leaves with downy mildew symptoms

Grapevine downy mildew is a disease of foliage caused by Oomycete Plasmopara viticola an endoparasite that develops inside grapevine organs and can infect virtually every green organ. Downy mildew is one of the most destructive diseases in wine-growing regions, drastically reducing yield and fruit quality. Traditional manual disease detection relies on farm experts. Human field scouting has been widely used for monitoring the disease progress, however, is costly, laborious, subjective, and often imprecise.

The influence of the soil on the phenolic composition of both grapes and wines : “the Grenache observatory”

La composition fine des raisins de Grenache noir est mal connue. Il est généralement admis une certaine variabilité de comportement de ce cépage qui se manifeste principalement sur la couleur des vins. De nombreux facteurs peuvent être à l’origine de cette variabilité : matériel végétal, pratiques culturales, types de vinification et terroir. Un travail de recherche concernant ce cépage a été engagé dans la Vallée du Rhône.
