Application of nitrogen forms such as nitrate, urea, and amino acids effects on leaf and berry physiology and wine quality

Moderate wine consumption – with the meals – represents one of the beneficial components of the traditional mediterranean diet (med diet) and a positive item in the med diet score [1,2, 3]. The med diet is considered one of the best diets in the world and the world health organisation (who) identified this eating pattern as an effective strategy to prevent non-communicable diseases (ncd), since it is associated with lower disease occurrence and all-cause mortality [4] . Numerous well-conducted epidemiological studies have also reported that light-to-moderate intake of wine/alcoholic beverages is not only related to a reduced risk of cardiovascular disease, but also to all-cause mortality.

Context and purpose of the study. Italy hosts diverse grapevine varieties crucial for viticultural biodiversity. Preserving this biodiversity is essential for maintaining a diversified genetic pool and addressing future challenges such as climate change and emerging plant diseases.

High-volume mass-market white wines production method by means of harvest-deferred fermentation from desulphited musts allows an efficient business management by avoiding the seasonality in wine sector.

In California vineyards, irrigation is considered as one of the most important decisions growers will make. Recent research has revealed that decisions of when to begin irrigation and how much water to apply have considerable consequences for final grape quality and hence wine quality. However, it is unclear whether and to what extent the average winegrape grower uses objective data to begin irrigating or to determine the amount of water to apply.

Rootstocks continue to serve as the first line of defence against phylloxera in viticulture; however, to mitigate the impacts of climate change, future viticulture will require novel, improved rootstock varieties. As conventional rootstock breeding is extremely time-consuming, modern genomics-assisted approaches are urgently needed.
