Effect of irrigation and soil type on root growth and distribution of Vitis vinifera L. cv. Nero d’Avola grown in Sicily

Abstract

[English version below]

L’essai a été effectué dans un vignoble du cépage Nero d’Avola greffé sur 1103 Paulsen dans un terroir de la D.O.C Alcamo en Sicile. Le système de conduite des vignes était à espalier, la taille à cordon coursonné et l’irrigation à goutte a goutte. On a été confrontés trois types de traitements: A) vignes non irriguées; B) vignes irriguées quand le potentiel hydrique foliaire (potentiel de base) était au dessous de –0.7 MPa, pour maintenir le potentiel hydrique foliaire de base au dessous de –0.4 MPa jusqu’à la récolte; C) vignes irriguées en maintenant le potentiel hydrique foliaire de base au dessous de –0.4 MPa du débourrement à la récolte. Dans le parcelle de l’essai étaient présents trois types de sol argileux: Entisol dans le partie haute de la colline, Inceptsol à moitié de la colline et Vertisol à la vallée de la colline. On a déterminé la distribution du système racinaire de la vigne dans les différentes types de sol par rapport aux différents traitements hydriques en emploient la méthode du contact. L’irrigation a été le facteur le plus important pour la croissance et la distribution du système racinaire; on a aussi noté que la stratégie de l’apport hydrique doit être calculée par rapport au type du sol ou vice-versa; par conséquence c’est le type de sol que détermine la stratégie d’irrigation la plus appropriée. Pour étudier les rapports entre le système racinaire et le feuillage et toute la biomasse il faut tenir en compte l’efficience du système racinaire, particulièrement dans les conditions dans lesquelles les divers effets limitants sont réduits, comme se vérifie dans les endroits secs où on emploie l’irrigation.

The trial was carried out in a Nero d’Avola vineyard, grafted onto 1103Paulsen, and located in Alcamo D.O.C. area (Sicily). Vines were trained to a vertical trellis system, spur pruned and drip irrigated. Three treatments were applied: A) vines grown without irrigation water; B) vines irrigated when the pre-dawn leaf water potential was above -0.7 MPa and to maintain pre-dawn leaf water potential at value below -0.4 MPa until harvest; C) vines irrigated in order to maintain pre-dawn leaf water potential at value below -0.4 MPa, from budbreak to harvest. Three clay soil types were present in the vineyard: Entisol, on the top of the hill, Inceptisol, halfway down the hill and Vertisol, at the bottom of the hill. The distribution of the root system in the different soil types and in relation to the different irrigation treatments was determined by using the contact method. Irrigation was the most important factor in determining the quantity and distribution of roots, even if it was also noted that the irrigation strategy must be calculated in relation to the type of soil or vice-versa, so that the type of soil determines the most suitable irrigation strategy. For the study of the relationships between root systems and area, it is necessary to take the efficiency of the root systems into account, especially in conditions in which the various limiting effects are reduced, as happens in the dry environments where irrigation is used.

SIP and save the planet: a sensory and consumer exploration of australian wines made from potentially drought-tolerant white wine grapes

In order to attenuate the effects of climate change on the ability to cultivate quality wine grape vines in Australia, it is essential to adapt to the projected less favourable Australian climate scenarios. One response may be to convert a portion of the current grapevine plantings to those varieties that demand less water and can tolerate increased heat. This investigation aimed to (i) generate sensory profiles and (ii) obtain knowledge about Australian wine consumers’ preferences and opinions of Australian wines made from potentially drought tolerant, white wine grape varieties not traditionally cultivated in Australia. A Rate-All-That-Apply (RATA) sensory panel (n = 49) generated sensory profiles of 44 commercial white wines made from 7 different white grape varieties (Arinto, Fiano, Garganega, Greco, Verdejo, Verdelho and Vermentino), plus two benchmark examples each of an Australian Riesling, Pinot Gris and Chardonnay wine.

Influence of wood chips addition during alcoholic fermentation on wine phenolic composition

This study investigates the effect of wood chips addition during the alcoholic fermentation on the phenolic
composition of the produced wines. A series of wood chips, originating from American, French, Slavonia
oak and Acacia were added at the beginning of wine alcoholic fermentation. Besides, a mixture consisting
of 50% French and 50% Americal oak chips were added during the experimentation. The wine samples
were analyzed one month after the end of malolactic fermentation, examining various chemical
parameters such as total anthocyanins, total phenolic content, tannins combined with protein (BSA) and
ellagitannin content.

Influence of dehydration and maceration conditions on VOCs composition and olfactory profile of Moscato Bianco passito sweet wine

Among the Vitis vinifera L. cv. Moscato, Moscato Bianco is the oldest and most cultivated one in Europe (1). According to the OIV Focus 2015, Italy is the country with the largest cultivated area of Moscato Bianco with about 12500 hectares (2), that is used to produce well-known wines (i.e., Moscato Passito in Piedmont, Moscato di Trani in Puglia, and Moscatello di Montalcino in Tuscany), mainly obtained from partially dehydrated grapes (1). Different dehydration techniques can strongly modify the chemical compounds of oenological interest, among which Volatile Organic Compounds (VOCs) (1) that are the main responsible for the varietal sensory character of the final wine.

Investigating three proximal remote sensing techniques for vineyard yield monitoring

Yield monitoring can provide the winegrowers with information for precise production inputs during the season, thereby, ensuring the best possible harvest. Yield estimation is currently achieved through an intensive process that is destructive and time-consuming. However, remote sensing provides a group of proximal technologies and techniques for a non-destructive and less time-consuming method for yield monitoring.The objective of this study was to analyse three different approaches, for measuring grapevine yield close to harvest.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.
