17th INTERNATIONAL SYMPOSIUM GiESCO 2011
Group of International Experts of Vitivinicultural Systems for CoOperation
Asti – Alba, Italy
August 29 th – September 2 nd , 2011
GESCO was the original acronym for "Groupe d'Etude des Systèmes de COnduite de la vigne". It was started, as European
group, by Alain Carbonneau and others, and was originally, as the name implies, focused on training systems. The group
grew, become International, and the focus on training systems was dropped. Recently the group renamed itself to:
"Group of International Experts of vitivinicultural Systems for CoOperation".

Foreword to the 17th Symposium GiESCO 2011
The 17th International Symposium GiESCO 2011 (Group of International Experts of Vitivinicultural Systems for
CoOperation) takes place from August 29 th till September 2 nd at the "Viticulture and Enology Sciences Master" of Turin
University (Asti and Alba) - Italy, under the patronage of OIV (International Organization for Vine and Wine), Accademia
Italiana della Vite e del Vino, Piedmont regional Government, Italian Agricultural Minister, and the Chaire UNESCO
Culture et Traditions du Vin. The Symposium covers many fields of viticultural sciences, and collects about 150
presentations (oral and poster) by researchers and scientists from 17 countries.
GESCO was the original acronym for "Groupe d'Etude des Systèmes de COnduite de la vigne". It was started, as
European group, by Alain Carbonneau and other colleagues, and, as the name implies, was originally focused on training
systems. The group grew, took in researchers out of Europe, and extended its scientific interests to most of the topics of
all viticulture; this is why the group recently renamed itself as GiESCO.
The periodical meetings of this group are good occasions to renew personal contacts, as well as to make new ones, in
order to facilitate cooperation in research and education.
The 17th International Symposium GiESCO 2011, for many viticulturists, is also a good occasion to know Italian
viticulture, especially the Piedmont's one, which is renowned worldwide.
I would like to dedicate this Symposium to the memory of Prof. Italo Eynard that, besides to be an excellent viticulture
scientist and professor, was an enthusiastic promoter of the GESCO group at its beginning.
Finally I would like to thanks all people involved in the organization of this event, and all institutions and companies that
have financially supported the symposium or offered donations: without their contribute, this meeting would have been
impossible to realize.

Summary
The shading of the productive belt produces clusters with
minor sugar contents and higher acidity. Further it creates
optimal conditions for the establishment of Botrytis cinerea. The
present work aims to analyze the effects of leaf removal on
Sauvignon blanc and Grechetto with three different ways of
defoliation (leaf removal to east, west and total) in addition to the
control test (no defoliation). The study was carried out in the
vineyard “Arnaldo Caprai, Montefalco” (PG) and consisted in
collecting data during the period from 2007 to 2010 (for
Grechetto only in 2007, 2009 and 2010). In the vineyards which
are located on a plain, a spurred cordon system was applied, the
rows were north-south orientated and cover cropping was made
on soil. For each year the main vegetative–productive and
analytical parameters, as well as the polyphenolic content of
grapes, have been observed; for each thesis of 2010 the curves of
technological and polyphenolical ripening were identified, with
the aim to better understand the course of those components,
because they may cause oxidation in wines, above all in the white
ones, leading to browning and aroma losses.
From the years' average resulted that in Grechetto the not-
defoliated vines had the highest average cluster weight with a
medium sugar content, a good level of acidity and the lowest pH.
It could be further seen that in 2010 in Grechetto the notdefoliated
vines recorded the highest quantity of malic acid
together with the west-defoliated ones; from a polyphenolical

point of view, west defoliation maintains a constant percentage of
polyphenols in skins during the three years of observation, even
if sometimes the quantities are low. Sauvignon with east
defoliation shows a good sugar and acidity level, maintaining a
medium–low pH; in addition east defoliation leads to a reduced
percentage of polyphenols in skins in 2008 and 2010, whereas the
control test presents in every year medium–low levels of all the
analytical parameters.
INTRODUCTION
Times and effects of leaf removal: generally, this
operation is made between flowering and veraison with the
primary purpose of improving the lighting and the aeration
of grapes (Poni, 2006). In practice, leaf removal can be
also made before vintage, facilitating ripening, improving
plant resistance to pests and accelerating harvesting
(Valenti, 1997); many studies have demonstrated that early
defoliation can lead to a reduction of sugars, an increase of
acidity (Eynard and Dalmasso, 1993) and, further, to a
drop of fruits and a reduction of bud fertility (Candolfi-
Vasconcelos and Koblet, 1990). Some studies (Eberle and
Persano, 2006) have shown that premature loss of leaves
reduces the phenomenon of burns, because the plant is able
to react by growing out new leaves from secondary shoots,
creating a kind of covering, though only partially.
Last update Sept. 9 th 2011

The benefits of defoliation can be directly seen on
grape composition: increase of sugars, colour, quantity of
total polyphenols, higher aromaticity, reduction of total
acidity (caused by a reduction of malic and tartaric acids)
(Lakso and Kliewer, 1975; Percival et al., 1994) and
increase in pH (Guidoni et al., 2005); generally, there is a
qualitative and quantitative increase of production
(Valenti, 1997; Cargnello, 1992; Poni, 2003). It is however
necessary to consider the depth of canopy because
defoliation applied on not very deep walls, reduces the
photosynthetic activity and can also cause a deterioration
of grape quality (Reynolds et al., 1994; Spayd et al.,
2002).
Main effects of defoliation on the bio-synthesis of
polyphenolic and aromatic components: leaf removal
increases the polyphenolical content, because it improves
their biosynthesis which is optimal at temperatures
between 20-30 °C; temperatures higher than 37 °C lead to
an inhibition of anthocyanins synthesis encouraging also
the degradation of the polyphenols (Bergqvist et al., 2001;
Spayd et al., 2002; Mori et al., 2007). Further, light has an
important role for the synthesis of carotenoids whose
content is relevant for the complexity of the aromatic
profile of a large number of vine grape varieties (Wirth et
al., 2001; Strauss et al., 1987; Winterhalter et al., 1990).
Main actions of grape's polyphenol content and
effects on vine: polyphenol components are very important
for the plant because they have a protective function
against UV radiation limiting the formation of free
radicals. In wine, and above all in white wines, these
polyphenolic components can have a negative effect,
because they are highly reactive with oxygen; they oxidize
themselves and other components of wine (i.e. the
aromatic molecules…); the consequence is the creation of
brown compounds not desired in wines and whose reaction
can be faster with the catalytic activity of Fe ++ and Cu + .
The oxidation easiness depends on the nature of the phenol
base unit (i.e. musts rich of catechin oxidize easier…). In
wines, polyphenols are in general compounds which give
structure and complexity (Riberau-Gayon et al., 2005).
MATERIAL AND METHODS
The trial was carried out in the vineyard “Arnaldo
Caprai” (PG) in the years 2007-2010: for the Sauvignon
blanc, data were collected during the entire period,
whereas for the Grechetto, no data were collected for 2008
because of sanitary problems. When clusters reached 10%
of coloured berries, for both cultivars, defoliation was
carried out manually and only along the cluster belt. Thesis
were conducted in the following way: control test (not
