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.

Post-plant nematicide timing for northern root-knot nematode in Washington wine grapes

Vigor declines in older vineyards and poor vine establishment in replant situations have been attributed to plant-parasitic nematodes. The northern root-knot nematode, Meloidogyne hapla, is the most prevalent plant-parasitic nematode species found in Washington wine grape vineyards. Management for nematodes in established vineyards is limited to the application of post-plant nematicides. We are evaluating new nematicides that are currently not registered in grape for their efficacy in controlling M. hapla and a part of that evaluation includes improving the alignment of nematicide application timing with the vulnerable second-stage juvenile (J2) life stage of M. hapla.

Quality of Merlot wines produced from terraced vineyards and vineyards on alluvial plains in Vipava valley, Slovenia (pdo)

Rationalising the impact of time, light, temperature, and oxygen on the evolution of rosé wines by means of a surface response methodology approach

The widespread use of flint glass bottles for rosé wines is driven by consumer preference for color as a key choice factor.

Assyrtiko wines of Santorini produced by different autochthonous yeasts: Differences in aromatic and organoleptic profiles

Different yeasts were isolated from spontaneous fermentation of Assyrtiko grape must in Santorini Island, Greece. Molecular typing revealed the presence of three Saccharomyces cerevisiae strains (S9, S13, S24) and one strain of the yeast species Nakazawaea ishiwadae (N.i). The four isolated strains were further tested in laboratory scale fermentations of Assyrtiko must in pure inoculation cultures and in sequential inoculation (72 hours) of each S. cerevisiae strain with the strain of N. ishiwadae. All fermentation trials were realised in duplicate.
