Dans ce travail est exposé : 1- une ‘essentielle présentation des « vieux-nouveau » modèles productifs appartenant au groupe appelé "UNIC" du "Conegliano Campus", comme le «Prosecco modifié Conegliano », le «NiofProsecco» et le «ProRab",
Mesoclimate modeling of a vineyard may have important implications, mainly, for management of wine-growing strategies.
On exposera les résultats quantitatifs-qualitatifs et ceux économiques, environnementale, sociaux, existentiels, éthiques d’une façon « MétaÉthique» selon la «Grande Filière MétaÉthique» du Conegliano Campus
Knowledge about grapevine leaf and canopy age is relevant when studying plant reaction to the environment.
In grapevine, monitoring canopy architecture is important for the assessment of growth, vigour and light transmission to the flowers and fruit zone.
In a vineyard located at Alcains (Beira Interior, Portugal), planted in 2004 with ‘Trincadeira’, ‘Touriga Nacional’, ‘Aragonez’ and ‘Alfrocheiro’ all grafted on ‘SO4’ rootstock, spaced 3×1 m, and trained as a single vertical curtain, the effect of crop load in vine production and quality was studied by non-linear fitting of crop load
The trellis and training systems are important technical resources to balance vigour, yield and quality in vineyards.
The investigation was conducted from 2009 to 2012. on cv. Chardonnay in the productive vineyard.
Adjustments of viticultural practices are required to adapt to climate change. In particular, vineyard management that vary the fruit to leaf area ratio is an important option to maintain and enhance fruit quality.
The impact of canopy structure on spatial leaf area distribution, canopy microclimate and fruit quality has been widely studied.
In warm and dry climates, the use of porous systems should be required in order to allow a better leaf distribution inside the plant, causing more space in the clusters area and enhancing determined physiological processes so in the leaf (photosynthesis, ventilation, transpiration) as in berry (growth and maturation).
The phenolic profile, as determined by the relationship between different compounds, is characteristic of each grapevine variety and it is considered as a chemotaxonomic parameter for the classification and differentiation of red varieties of Vitis vinifera.
In order to reduce the costs of pruning and increase the income, the effects of mechanical pruning (hedge pruning) and the application of different soil amendments (municipal solid waste, sewage sludge, char dust and cow manure) were evaluated.
Plant architecture modifies microclimate – air relative humidity (RH%) and temperature (T°C)- in clusters area, which influences incidence of fungal rots.
Even though convenient for grape berry quality for wine making in grapevines, water stress is known to provoke negative physiological effects on plants.
