Sviluppo vegetativo del Nebbiolo nell’area di produzione del Barolo DOCG: influenza sulla qualita’ della produzione

Abstract

Environment features and management operations on shoot and leaves modify the canopy during the vegetative season, changing the grapevine microclimate and the ratio between photo synthetic sources (the canopy) and productive sinks (the grapes). The aim of the present study was to evaluate on several vineyards the evolution in the season of the canopy development, in order to relate the vegetative behavior of the vine with the quality of grapes at harvest. For two consecutive years canopy development was assessed on 30 Nebbiolo vineyards in the Barolo area, using the point quadrat method. Size and structure of the canopy were assessed in June and September. Yield and qualitative characteristics of the must were determined at harvest. Total leaf area measured at the end of the vegetative season was directly correlated with yield, but it was not correlated with sugars and phenolic accumulation in the grape. However, both sugar and phenolic content in the must were proportional to the increase in canopy area observed between June and September, which is affected by plant vigor and vineyard management techniques (e.g. topping). The results suggest that the quality of Nebbiolo grapes in the Barolo area is affected by environment-induced vigor on one side, and by canopy management on the other side.

Investigating the role of endophytes in enhancing grapevine resilience to drought

Grapevine is a crop of great economic importance for several countries. The intensification of grapevine production has mostly been sustained by the increasing use of water resources at the expense of the environmental water balance. Moreover, in the last decades, climate change and the consequent expansion of drought have further compromised water availability, making current agricultural systems even more fragile both ecologically and economically. Recently, many research groups have highlighted the important role of endophytes in facilitating plant growth under optimal or stressful conditions. Within the framework of the PRIMA project, we aim to investigate the possible exploitation of the natural endophyte biodiversity as a sustainable tool to make grapevine plants more resilient to water deficit environmental conditions.

Overcoming habit formation in the production of wine

Evidence indicates that climate change affects the environment, human health, and well-being via drought, increasing greenhouse effect, and climatic catastrophes. As the wine sector is also negatively affected by climate change, the role of climate change mitigation and adaptation policies is important in wine production. One example of an adaptation policy is the implementation of grapevine genetics (duchene, 2016), while organic farming may be used as an approach to mitigate the consequences of climate change (vinci et al., 2022). To this end, the european commission’s objective is to reach the european green deal target of at least 25% of the european union’s agricultural land under organic farming by 2030.
