Leaf area management affects grape nitrogen content
Background and aim: The presence of certain forms of nitrogen in grape must at harvest is necessary to ensure a smooth fermentation and has an influence on the final quality of the wine. A trial was set up to show the impact of the trimming height on the nitrogen...
Estimation of Leaf Area Index in vineyards by analysing projected shadows using UAV imagery
Background and aim: A few decades ago, farmers could precisely monitor their croplands just by walking over the fields, but this task becomes more difficult as farm size increases. Precision viticulture can help better understand the vineyard and measure some key...
Screening of rhizosphere-associated bacteria for potential use as biological fertilisers and pathogen control
Background and aim: The rhizosphere-associated microbiome has diverse functions that support plant growth and health, varying among plant species, vegetation growth stages and environmental habitats. This microbiome includes a group of bacteria denominated plant...
Effect of cover crops and irrigation on grapevine and berry physiology – Tempranillo
Background and aim: In addition to irrigation, other viticultural practices such as soil management can be applied to improve grapevine (Vitis vinifera L.) quality responses and attenuate unfavourable environmental conditions. Cover crops in the interrow of...
Wine fermentation performance of indigenous Saccharomyces cerevisiae and Saccharomyces paradoxus strains
AIM: The role of yeast in wine quality is very important. The use of selected autochthonous yeasts is becoming more and more frequent in enology, not only to obtain a diversification of wines, but also as a link between the wine and its territory of origin. The...
The influence of must fining on pinking
AIM: “Pinking” is a term used to define an abnormal pink coloration assumed by white wines in certain cases. Despite the many hypotheses about the causes of this phenomenon, pinking still represents an issue for the wine industry. In the absence of reliable...
