Il monitoraggio meteorologico come strumento per la gestione della variabilità climatica in Franciacorta

Abstract

[English version below]

Nel 2007 è stata avviata una ricerca nell’areale di produzione del Franciacorta DOCG che ha riguardato un ampio numero di vigneti di Chardonnay con riferimento ai quali sono stati acquisite le serie storiche dal 2001 relative a (i) decorso delle epoche fenologiche, (ii) curve di maturazione e (iii) dati prodotti dalla rete meteorologica consortile. Tali dati hanno permesso di produrre un modello empirico agrofenologico relativo allo Chardonnay nell’areale considerato e di calibrare e validare un modello meccanicistico di simulazione della produttività primaria, chiamato SIM_PP.

In 2007 a research was started on an high number of vineyards in the Franciacorta AOC area. From 2001 to 2009, phonological stages records and ripening kinetics data were collected. Starting from phenological data, an empiric agrophenological model was build, in order to estimate principal stages by using daily cumulated temperature. Furthermore, ripening kinetics were compared to mechanicistic model simulations (SIM_PP, Mariani and Maugeri, 2002). Starting from air daily temperatures, SIM_PP simulates the Net Primary Production, allocation dynamics in sink organs and the sugars storage in berries, using a mechanism based on transpiration and mass transport flux.
The comparison between real in-field situation and gathered simulations allowed to evaluate mechanicistic and empirical models performance.

Preliminary studies on polyphenol assessment by Fourier transform-near infrared spectroscopy (FT-NIR) in grape berries

NIR spectroscopy has widely been tested in viticulture as powerful alternative to traditional analytical methods in the field of quality evaluation. NIR instruments have been used for assessing must and wine quality features in several works, but little information regarding their application on whole berries for polyphenol determination is available.

Bio-acidification of wines by Lachancea thermotolerans

Insufficient acidity in grapes from warm climates/vintages is commonly corrected through addition of tartaric acid during vinification, and less so with other organic acids. An alternative approach involves bio-acidification with the yeast Lachancea thermotolerans (LT) via lactic acid production during fermentation.

Skin And Seed Extracts Differently Behave Towards Salivary Proteins

Background: Polyphenols extracted from skins and seeds showed different sensory attributes including astringency and bitterness. In previous studies, it has been demonstrated that extracts obtained either from skins or seeds interact differently with salivary proteins.

Freeze-thaw temperature oscillations promote increased differential gene expression during grapevine bud dormancy

In northern cold climate conditions, chilling requirement fulfillment in dormant grapevine buds is slowed or stopped by subzero temperatures impacting the transcriptional processes needed to complete chilling requirement. Cabernet Franc and Reisling in Geneva, NY were used to determine the impact of natural oscillating temperatures on grapevine bud transcriptional activity during light and dark periods of a two-week period in January with fluctuating diurnal winter temperatures. Cabernet Franc and Reisling bud samples were collected at 32 time points during the natural vineyard temperature cycle at 6:00 (dark), 14:00 (light) and 18:00 (dark) hours) to monitor gene expression in consecutive freezing and non-freezing temperature oscillations. Genotype, light and dark, and temperature oscillations conditions were explored.
