Campania region grapevine patrimony: a determination of the heat requirement of 19 nearly all-native ultivars. Nine years of observations.

Abstract

[English version below]

Nous avons peu d’informations sur les cépages cultivés dans la région de la Campania (sud de l’ltalie). En particulier insuffisant sont les études sur les besoins thermiques de tels cépages. Les études sur les besoins thermiques des cépages peuvent contribuer au positionnement correct des cultivars dans les zones capables d’optimiser le rapport génotype-environnement des cépages du quel dépend, l’expression qualitative de la production. Pour les dites motivations nous avons effectué la présente étude, dans laquelle nous avons déterminé les conditions thermiques de 19 cépages presque tous indigènes de la Région, ayant comme référence le modèle proposé par AMERINE et WINKLER (1944). L’étude qui a déterminé une exigence de la chaleur des variétés étudies variables de 1625 degré-jours ( cv Fiano) a 2011 degré-jours (Bianca Zita), ajoute une autre étape à la connaissance du patrimoine viticole de la Campania.

 

There is little information on the grapevines cultivated in the Campania region (south of ltaly). In particular insufficient are the studies on the thermal requirements of such grapevines. Trials on the thermal needs of the grapevines may contribute to the correct positioning of the cultivars in areas able to optimise the environment genotype ratio of a cultivar on which, qualitative expression of the production depends. For said motivations it has been set up the present study, in which it was determined the thermal requirements of 19 cultivars nearly all native of the Region, having like reference the model proposed by AMERINE and WINKLER (1944). The study that evidenced an heat requirement of the studied cultivars variable from 1625 degree-days (cv Fiano) to 2011 degree-days (Bianca Zita), adds an other step to the acquaintance of the Campania grapevine patrimony.

Effect of soil particle size on vine water status, leaf abscisic acid content and berry quality in nebbiolo grapes

AIM: We investigated the effect of soil texture on grapevine response to water stress, leaf abscisic acid concentration and berry quality, in two adjacent vineyards located in the renewed Cannubi hill of Barolo (Langhe area, CN, North-West Italy).

Enhancement of the terroir

The terroir is today the most important factor of production and development in the wine sector. In a context where the commercial challenge is taking place all over the place, the distinction between traditional and “new” producing countries is not only a geographical, cultural and technical counter position but also, and above all, a legal one. Indeed, the system of standards present in the “old world” (plantation rights, production decrees, yields per hectare, etc.) which may represent, in the short term on the global market, constraints to development and product innovation must become an opportunity. But threats become opportunities, if we work, from the vine to the market, via communication, more on the elements of difference than on those of affinity.
