Chemical activation of ABA signaling in grapevine through ABA receptor agonists

La maturité optimale est définie en fonction du style de vin désiré, qui est fonction du marché. Le sol et le climat ont un effet sur la typicité des vins. Le niveau qualitatif des raisins et des vins, et le potentiel pour obtenir différents styles de vin est déterminé par l’association des caractéristiques naturel du terroir et les technologies mises en

Conventional vineyard practices have lead in many environmental disturbances as erosion, soil compaction, loss of organic matter and soil biodiversity, water contamination

The Fregoni bioclimatic index (IF) considers the daily temperature range during the ripening month and the number of days with temperature below 10°C.

Powdery mildew, caused by Erysiphe necator, is a widespread disease that causes high economical losses in viticulture. The main strategy to control the disease is the recurrent application of sulphur based phytochemical compounds. However, in order to reduce their accumulation in the environment and promote the sustainability of the sector, the European Commission has applied restrictions to the number of pesticide treatments and the maximum quantity of fungicides to be applied in viticulture. Seaweeds, in particular macroalgae, are marine resources rich in sulphated polysaccharides with bio-protective potential for the plant, representing an environmentally-friendly alternative approach for sustainable wine production.

New breeding techniques (NBTS) could play a significant role in the genetic improvement of grapevine by producing new grape varieties with improved quantitative and qualitative characteristics. However, the application of these new techniques faces some technical challenges. One of the challenges is the generation of embryogenic calluses, which are not only difficult to obtain but it is also difficult to maintain their competence during in vitro cultivation, and thus regenerate plants without defects.
