Caratterizzazione varietale della CV. Vranac del Montenegro: primi risultati

Abstract

[English version below]

Questo studio ha permesso di raccogliere alcune informazioni sul profilo chimico della cultivar Vranac coltivata in Montenegro. L’uva ha mostrato di raggiungere un buon accumulo zuccherino indipendentemente dall’annata anche se coltivata su suoli diversi. Può raggiungere un buon tenore di antociani e un discreto contenuto di tannini, presenta un profilo antocianico a prevalenza di malvidina-3-G con tenori elevati di antociani acilati. Dal punto di vista aromatico si tratta di una cultivar neutra con un profilo glicosidico a prevalenza di benzenoidi. Dal confronto tra i vini sperimentali e quelli del commercio si può osservare che le potenzialità del vitigno sono buone ma vanno potenziate con un’adatta tecnica di vinificazione per cui saranno necessarie ulteriori prove tecnologiche.

This study has allowed us to gather some information on the chemical profile of Vranac cultivars grown in Montenegro. The grape has been shown to achieve good sugar accumulation independent of the year even if grown on different soils. It can reach a good content of anthocyanins and medium of tannins. Malvidina-3-G was predominant in the anthocyanic profile and the levels of acylated anthocyanins were high. It is a neutral cultivar with a prevalence of glycosidic benzenoids in the aroma profile. The comparison between the experimental and commercial wines can assume that the potential of the grapes are good but must be reinforced with a suitable winemaking which will require further studies.

Training vineyards resilience to environmental variations by managing vine water use

The challenges of the century for viticulture relate to coping with climate change and the loss of biodiversity in a downturning socio-economic context. Now more than ever, the vine and wine industry needs to be resilient to maintain and ensure a future for its heritage. An innovation of capital importance, in line with recently published research, deals with developing new methods of training our inherited and newly planted vineyards to better withstand environmental variations such as drought and heatwaves but also unevenly distributed rains and temperatures.

Simulated climate change in a Mediterranean organic vineyard altered the plant physiology and decreased the vine production

This study focuses on investigating the effects of climate change on the plant physiology and berries of Vitis vinifera cv “Monastrell” in a commercial vineyard managed organically in Southeastern Spain (Jumilla, Murcia). For this purpose, open top chambers and rainout shelters were employed to simulate warming (~2-7 ºC, W) and rainfall reduction (~30%, RR) respectively. Additionally, a combination of both treatments (W+RR) was employed. Vines without either top chambers or rainout shelters were considered as control (C). The experiment was established in February of 2023. Predawn leaf water potential (measured using a pressure chamber), stomatal conductance (assessed with a porometer at mid-morning) and leaf chlorophyll and flavonoid content (measured using the Dualex® leaf clip sensor) were analyzed at veraison (5 months after the installation of structures).

Improving shelf life of viticulture-relevant biocontrol and biostimulant microbes using CITROFOL® AI as liquid carrier

Bacillus velezensis and Trichoderma harzianum are relevant microorganisms used in viticulture as biocontrol agents against pathogens of trunk (e.g. Phaeoacremonium minimum), leaves (e.g. Plasmopara viticola) or fruit (e.g. Botrytis cinerea), or as biostimulants, improving the resilience of plants against biotic or abiotic stressors through different direct and non-direct interactions.
In this biotechnological approach, formulation plays a crucial role. Controlling water activity in the product, thus stabilising microbial viability is key to ensuring effective application. We present the benefits of the citrate ester CITROFOL® AI (triethyl citrate) as a novel bio-based carrier liquid in microbial formulations. CITROFOL® AI is safe for humans and the environment, thus offering a promising base for sustainable treatments in viticulture.

Effect of terroir on the quality evolution of Cabernet-Sauvignon in Penedès A.0.C.

Le Cabernet-Sauvignon est un cépage très répandu dans la région du Penedès (Espagne) où cette variété peut bien s’adapter et donne des produits de haute qualité.

The vineyard of the future: producing more with less  

similar to other agricultural producers, grape growers face increasing pressure to improve productivity and production efficiency while reducing their environmental impact. Threats due to extreme climate events, as well as the uncertainty of available water and labor, provide significant challenges to the future of grape production. This presentation will provide an integrated overview of the tools and technologies being developed to address these issues and to help growers manage vineyards in the future, including vineyard design, remote and proximal sensing, automation, data management and decision support systems, and germplsm improvement. The potential impact of these advancements on vineyard productivity, fruit quality, and sustainability will be discussed.
