Progetto di zonazione delle valli di Cembra e dell’Adige. Analisi del comportamento della varietà Pinot nero in ambiente subalpino

Abstract

[English version below]

Nel 1990 la Cantina LA VIS ha intrapreso un progetto di zonazione dei terreni vitati allo scopo di acquisire le conoscenze scientifiche atte a consentire il miglioramento delle qualità dei prodotti. Tale progetto si è articolato su di una superficie di 2000 ettari ubicati lungo l’asta fluviale del fiume Adige da Trento a Salorno e del torrente Avisio da Lavis a Segonzano. Data la vastità dell ‘area indagata si è suddivisa la stessa nelle zone di Cembra, Lavis, Meano e Salorno.
Nell ‘ambito di tale progetto è stata posta particolare attenzione al comportamento della varietà Pinot nero, sia sotto gli aspetti vegeto-produttivi che su risultati ottenuti a seguito di prove di microvinificazione.
I parametri vegeto-produttivi presi in considerazione (valori medi quadriennali 1992-1995) hanno evidenziato come nelle quattro zone oggetto d’indagine la produzione non ha manifestato differenze statisticamente significative nei vari ambienti, anche se alcuni dei parametri influenzanti la resa presentano delle differenze fra loro, come ad esempio il peso medio del grappolo che a Cembra présenta i valori più bassi. Analizzando i parametri qualitativi, si evidenzia come a Cembra, conseguenza di una maggiore quota altimetrica, si ha un basso grado zuccherino, una più alta acidità totale e un minor pH. L’analisi organolettica dei vini ottenuti e la successiva elaborazione statistica ha evidenziato come nelle due annate d’indagine (1992-1993) nella zona di Cembra, si sono ottenuti vini con note di tipicità e gusto superiore alla média e si è potuto evidenziare come nell ‘unità pedologica CE2 di tale zona si sono avute sensazioni gustative ed aromatiche superiori alla media.
In 1990 Cantina LA VIS undertook a zonation project of the vine terrains for the purpose of acquiring scientific knowledge to improve product quality. This project was centered on an area of 2000 hectares along the banks of the Adige river from Trento to Salorno and the Avisio stream from Lavis to Segonzano. Due to its vast size the area under examination was divided into four zones: Cembra, Lavis, Meano and Salorno.
The project examined in particular the Pinot Nero variety, the vegetal-fertile aspects as well as the results of microvinification tests.
The vegetal-fertile parameters taken into consideration (averages values from 1992-1995) show that in the four areas production did not differ significantly under the various environments, even if some parameters affecting the yield do differ, as for example in Cembra the mean weight of the grape bunch was lower. By analyzing the qualitative parameters it was found that in Cembra, with a higher altitude, there was a lover sugar level, higher total acidity and a lower ph. Analysis of the organoleptic characteristics of the wines obtained and the successive statistical elaboration has shown that the two harvests in Cembra produced wines with a more superior flavor and typicality and pedologie unit CE2 of this area a higher than average flavor and aroma were evident.

The effects of reducing herbicides in New Zealand vineyards

Herbicides are commonly sprayed in the vine row to prevent competition with vines for water and minerals and to keep weeds from growing into the bunch zone. Sprays are applied before budbreak and reapplied multiple times during the season to keep the undervine bare. There is growing concern about the negative effects of herbicides on humans and the environment, and weeds in New Zealand have developed resistance to herbicides. Therefore, it is imperative that we reduce our reliance on herbicides in viticulture and incorporate methods that do not engender resistance.

Interest in measuring the grape texture to characterise grapes from different cultivation areas – Example of Cabernet franc from the Loire Valley

A two-bite compression test was applied on Cabernet franc grapes during two harvest seasons. The evolution of the texture parameters from véraison to harvest was studied and a new mechanical ripeness notion was introduced.

Using δ13C and hydroscapes as a tool for discriminating cultivar specific drought response

Measurement of carbon isotope discrimination in berry juice sugars at maturity (δ13C) provides an integrated assessment of water use efficiency (WUE) during the period of berry ripening, and when collected over multiple seasons can be used as an indication of drought stress response. Berry juice δ13C measurements were carried out on 48 different varieties planted in a common garden experiment in Bordeaux, France from 2014 through 2021 and were paired with midday and predawn leaf water potential measurements on the same vines in a subset of six varieties. The aim was to discriminate a large panel of varieties based on their stomatal behaviour and potentially identify hydraulic traits characterizing drought tolerance by comparing δ13C and hydroscapes (the visualisation of plant stomatal behaviour as a response to predawn water potential). Cluster analysis found that δ13C values are likely affected by the differing phenology of each variety, resulting in berry ripening of different varieties taking place under different stress conditions within the same year. We accounted for these phenological differences and found that cluster analysis based on specific δ13C metrics created a classification of varieties that corresponds well to our current empirical understanding of their relative drought tolerances. In addition, we analysed the water potential regulation of the subset of six varieties (using the hydroscape approach) and found that it was well correlated with some δ13C metrics. Surprisingly, a variety’s water potential regulation (specifically its minimum critical leaf water potential under water deficit) was strongly correlated to δ13C values under well-watered conditions, suggesting that base WUE may have a stronger impact on drought tolerance than WUE under water deficit. These results give strong insights on the innate WUE of a very large panel of varieties and suggest that studies of drought tolerance should include traits expressed under non-limiting conditions.

Cinétique de développement de la Pourriture Noble dans différents terroirs des Coteaux du Layon : mise au point d’une méthodologie

Dans la région des Coteaux du Layon, en Maine et Loire, l’effet terroir et son déterminisme sont étudiés dans le cadre de la production des vins liquoreux.
Ces vins sont le résultat d’une maturité poussée au delà de celle prévue par la nature afin de donner aux baies une teneur en sucre et en matière sèche très forte, pour mieux valoriser ces effets de la surmaturation, les baies sont récoltées selon la méthode des tries successives (Asselin et al, 1996). Ainsi, on ne récolte à chaque passage que les grains ayant atteint le niveau de concentration requis pour obtenir des vins à fort degré d’alcool avec des sucres résiduels.
