Influence of different environments on grape phenolic and aromatic composition of threeclone of ‘nebbiolo’ (Vitis Vinifera L.)

Abstract

The interaction between cultivar and growing environment is the base of wine quality and typicality. In recent time the behaviour of different clones within the same cultivar became another fundamental factor influencing the enological result. In order to clarify cultivar/clone/environment relations, a trial was carried out in 2008 studying the performances ofthree clones of ‘Nebbiolo’, grown in different environments: south-east Piedmont (hilly and characterized by a loamy and alkaline soil) and north-east Piedmont (a plain area characterized by a sandy and acidic soil). The results, although preliminary, indicated the different environments of cultivation have influenced quantitative and qualitative response of the same clone. Of particular interest the differences in phenolic composition which resulted quantitatively higher in the location of northern Piedmont compared to the southern sites, although qualitatively weaker as the anthocyanic profile was poorer in malvidin-3-glucoside and richer in peonidin-3-glucoside. These aspects may have relevant implication for the colour of future wine. The varietal aromatic profile, on the contrary, resulted stable between the environments, yet to fully understand the role of different factors affecting the aromatic quantitative differences further investigations are needed.

Postharvest elicitors and metabolic changes in wine grape berries

Wine grape berries respond to postharvest treatments with specific gaseous elicitors in terms of metabolic changes and composition. Short-term (3 days) high (30 KPa) CO2 treatment affects phenol compound concentration in skins of ‘Trebbiano toscano’ berries.

Outside and inside grapevine roots: arbuscular mycorrhizal fungal communities in a ‘nebbiolo’ vineyard 

In field conditions, grapevine roots are colonized by arbuscular mycorrhizal fungi (AMF). Little is known about the species composition of AMF communities associated to grapevine.

Modification on grape phenolic and aromatic composition due to different leafroll virus infections

Viral diseases are reported to cause several detrimental effects on grapevine. Among them, leafroll, due to single or mixed infection of GLRaV1 and GLRaV3, and rugose wood, associated to GVA, are considered the most widespread and dangerous.

Anthocyanins, flavonols and hydroxycinnamates of eight vitis vinifera cultivars from the balearic islands

In 2008 the anthocyanin, flavonol and hydroxycinnamate (HCT) contents of the skins of five coloured berry cultivars (‘Escursac’, ‘Esperó de Gall’, ‘Galmeter’, ‘Valent negre’ and ‘Vinater negre’), of two white cultivars (‘Argamussa’ and ‘Prensal blanc’) and of one weakly rose cultivar (‘Giró ros’), native from Balearic Islands, were characterized.

Evaluation of winegrape anthocyanins in the vineyard using a portable fluorimetric sensor: seasonal and water regime effects

Accumulation of anthocyanins (Anth) on whole winegrape (Vitis vinifera L.) bunches attached to the vine was monitored by a fluorescence-based sensor (Multiplex) on ‘Aleatico’ and ‘Nero d’Avola’. Different water regimes were applied.
