Valutazione comparativa di cloni di Pinot nero per la produzione di vini base spumante in alcuni ambienti del Piemonte

Abstract

[English version below]

Un vasto programma si riferisce alla verifica di 28 selezioni clonali di Pinot nero atte a vini base spumante. Gli impianti sono stati realizzati in diversi ambienti delle Langhe e del Monferrato nel periodo 1992-1996, in 57 vigneti diversi e su una superficie complessiva di circa 50 Ha. In ogni vigneto si è seguito uno schema sperimentale a blocchi randomizzati con densità di circa 4000 piante/Ha, sistema di allevamento assurgente in controspalliera e potatura a guyot. Nel presente lavoro si inizia a presentare i risultati relativi ai primi sette vigneti impiantati e ad 8 selezioni clonali di Pinot nero limitatamente ai parametri délia produzione nel triennio 1995-97.
Gli aspetti più significativi derivati dallo studio sono stati i seguenti:
– l’annata, intesa soprattutto come andamento climatico, ha esercitato un effetto molto importante sulla produzione di uva e sul peso del grappolo;
– Tra i vigneti considerati (siti) sono state riscontrate ampie differenze; quanto più un ambiente si è dimostrato favorevole, tanto più importanti sono state le produzioni delle diverse selezioni di Pinot nero e viceversa.
– Nell ‘ambito delle selezioni clonali si sono distiniti tre gruppi di cloni sulla base délia loro produttività: alta (cloni 292, 236, 375 e 459), media (clone 52) ed inferiore alla media (cloni 521 e 386)
– E verificata l’alternanza produttiva del Pinot nero negli anni e la sua elevata reattività ai siti ed alle condizioni climatico-ambientali.

A wide program has been build up in order to verify 28 Pinot noir clonal selections for high quality sparkling wines. 57 experimental vineyards have been planted over the period 1992-96 in diversified environments of Langhe and Monferrato for a total surface of about 50 Ha.
In every vineyard a randomized scheme was adopted with a density of about 4000 plants/ha, with low training system and Guyot pruning. The result related in this paper are about the yield of the first 7 vineyards and of 8 Pinot noir clonal selections, in the period 1995-1997. The most significant results are:
– The year, mainly as climatic conditions, proved an important effect on grape production and bunch weight
– Wide differences have been verified among the experimental vineyards (sites); as more an environment has been demonstrated favorable, so much the productions of the different Pinot noir’s selections have been important and vice versa.
– Three groups of clones have been found out on the base of the productivity: high (clones 292, 236, 375, 459), medium (clone 52) and lower of the average (clones 521 and 386).
– The Pinot noir yield variability over the years and his high reactivity to the climatic and environmental conditions have been verified.

Pedological criteria according to the French hierarchy of vintages, Appellations d’Origine Contrôlée (AOC): study of two toposequences located in the Burgundian “Côte”

The concept of terroir is defined by a set of natural and human factors. On the slopy vineyards of the Burgundian « Côte », the « Appellations d’Origine Contrôlée (AOC) » spread out according to the slope in their order of quality : « AOC Grand Cru » at the top, « AOC Premier Cru » and « AOC Village » and « Bourgogne » on the piemont. In order to correlate the hierarchy of the vintages with the evolution of the topographic and pedological criteria, two toposequences were studied, in Gevrey Chambertin (« Côte de Nuits ») and Aloxe Corton (« Côte de Beaune »).

La producción vitivinícola como fuente de impactos positivos en el medio seminatural

Wine is at risk of being labelled as a dangerous health product, based on studies that focus on its alcohol content. However, multiple studies suggest that moderate consumption is healthy. Changing the focus from health impacts to the environmental and socioeconomic impacts that wine companies cause, what can be said?

Predictive Breeding for Wine Quality: From Sensory Traits to Grapevine Genome

New pathogen resistant varieties allow an efficient and greatly reduced use of fungicides. These new varieties promise, therefore, an enormous potential to reach the European Green Deal aim of a 50% reduction of pesticides in EU agriculture by 2030.

The heritage behind the very old vineyards – The novelty with tradition for the future 

In Portugal, the prospection and conservation of representative samples of intra-varietal variability of grapevine has been carried out for 46 years, and in 2010 an infrastructure was created for the conservation of all these genetic resources – the portuguese association for grapevine diversity (porvid) experimental centre for the conservation of grapevine diversity. the aim is to save the genetic identity of ancient varieties to prevent their imminent loss and to preserve the raw material for current and future selections, thus adding economic value and sustainability to the vine and wine sector.
