Context
Climate change in the Mediterranean Region is
responsible for increasing temperature and frequency
of extreme events, such as prolonged periods of
drought
Climate change is intensifying the need to improve the
resource use efficiency of crops (e.g. water use
efficiency) and to increase yield, quality and stability of
productions, especially in high profitability and
vulnerable crops as grapevine
A deep knowledge of the plasticity of vine morpho-functional traits
in response to environmental constraints can help achieving the correct
management of cultivation factors towards sustainability
Objective
To monitor the resource use efficiency and resource allocation during vine
development up to must production:
•
With a
multi-disciplinary
approach
analysing the complex relationships between
parameters in the
continuum
environment-plant-must;
•
With a specific emphasis on the influence of
water availability
on the vine, grapes,
must and finally wine, in order to relate climate, plant water status and must
characteristics.
Vineyards were homogeneus for cultivar
and rootstock but characterized by
different pedo-climatic conditions
Study sites:
Four vineyards located
in La Guardiense farm
at Guardia Sanframondi (BN, Italy)

Results
Conclusions
Preliminary results of the reported study case confirmed the effectiveness of combining
in-vivo
measurements
and
retrospective analyses
to assess vine plasticity in response to
changing pedo-climatic conditions.
Differences in plant growth and production yield were observed among the selected
vineyards and highlighted by both
in-vivo
and retrospective analyses.
The approach proved to be promising for achieving a comprehensive understanding on
the impact of environmental constraints not only on plant behavior, but also on the
characteristics of the oenological products.

This study focuses on analyzing the relationships between vine hydraulics and wine production in Falanghina grapes to evaluate sustainability in the face of climate change challenges. By monitoring resource efficiency and allocation in vine development up to must production, the researchers aim to understand the influence of water availability on grapevines, grapes, and wine quality. Using a multidisciplinary approach and in-vivo plant monitoring, the study assesses the eco-physiological history of vines in different vineyards and how cultivation practices and climatic variables impact grape yield and quality.
