Somatic embryogenesis and polyploidy in grapevine: morphological shoot and leaf traits variations

Rapid climate changes and increasing biotic pressures compromise grapevine production systems by threatening grape quality and production yields, thus increasing phytochemical dependence as a widely adopted mitigation strategy.

Inter-row soil tillage in vineyards, stimulates vigor and production due to the absence of competition for water and nutrients, however negatively affects organic matter content, soil erosion, and compaction, resulting in reduced fertility. In this study, we investigated the effects of different cover crop management approaches, including cultivation type and termination timing, on the physiological and productive responses of a Glera vineyard.
The experimental trial was conducted in Precenicco (UD) from 2019 to 2021. A commercial mixture for autumn cover cropping was sown in alternating rows, and the sowing pattern was changed each year.

Strecker aldehydes (SAs) are volatile compounds that significantly influence wine aroma and quality, contributing notes such as “cooked vegetable” (methional), “honey” (phenylacetaldehyde), and “malt” (2-methylpropanal, 2-methylbutanal, 3methylbutanal).

Nel presente studio si è ricercata la possibilità di associare l’uva al territorio mediante parametri chimici indipendenti da variabili climatiche ed antropiche.

Since 1998, the GiESCO (previously named GESCO: Groupe d’Etude des Systèmes de COnduite de la vigne) has provided the scientific community with relevant contributions to the study of terroirs. Here is a synthesis of the main terroir-related fields and the major ideas the GiESCO has developed: Basic Terroir Unit and climate, Vine Ecophysiology and microclimate – moderate drought, Vineyard heterogeneity and new technologies, Viticultural Terroir Unit and canopy management, Terroir – Territory and man.
