Table-Grape Cultivation in Soil-Less Systems: A Review
2022
Table grape (Vitis vinifera L.) is considered to be one of the most popular fruit crops in the world. Italy is the leading table-grape producer in the EU and is the main European exporting country. However, to stay competitive, new solutions and perspectives, including varietal renovation, are now needed in addition to the already well-established Italian table-grape production lines consisting of conventional open-field cultivation and greenhouse cultivation. One of these new perspectives is represented by the development of table-grape soil-less cultivation systems (TGSC) under greenhouse. In fact, TGSC systems are alleged to offer many advantages in terms of the advancement of berry matu…
Analisi multitemporale delle relazioni tra parametri produttivi e indice di vegetazione in viticoltura
2014
L’efficacia degli interventi agronomici dipendono dalla capacità di programmazione in termini di tempo e intensità di intervento. Questultimi aspetti possono essere calibrati tramite una corretta conoscenza delle caratteristiche produttive e qualitative dei parametric di campo e della loro variabilità nel tempo e nello spazio. La viticoltura di precisione fornisce un supporto valido alla definizione della variabilità di campo e temporale dei parametric vegetative e produttivi. Questo lavoro sintetizza due anni di viticoltura di precisione in Sicilia, nelle campagne agronomiche consotte nel 2012 e 2013 in due aziende vitivinicole “Tenute Rapitalà” e “Donnafugata”. L’indice di vegetazione nor…
Messa in opera di un vigneto con sistema GPS e tradizionale
2016
La progettazione del nuovo vigneto non può prescindere oggi da una attenta analisi non solo del sito ma anche dei materiali che saranno impiegati per la realizzazione della struttura portante della vegetazione. La tecnoloigia Gps applicata alla messa in opera dei pali per la preparazione di un vigneto a controspalliera ha permesso di ottenere un impianto preciso anche in presenza di terreni in pendenza, con una minore usura degli scuotitori, assenza di rottura dei pali e tempestività di intervento.

In semi-vivo antagonism of Acremoninum byssoides towards Plasmopara viticola
2008
In previous laboratory tests the culture filtrates and the crude extracts obtained from Acremonium byssoides were shown to completely inhibit Plasmopara viticola sporangia germination. A study was thus undertaken in order to investigate on the possible inhibiting activity of the hyphomycete towards pathogenesis of the oomycete in grapevine. A. byssoides was cultivated on malt-extract agar (MEA) to obtain pure colonies and on maltextract broth (MEB) to obtain culture filtrate and crude extract. Healthy leaves of grapevine were put in Petri dishes containing sporangia suspended in: deionized sterile water, malt-extract broth, dimethylsulfoxide (DMSO), culture filtrate, crude extract and a sus…

Presentazione convegno
2022
The idea behind this Conference is to promote and disseminate legal and digital forms capable of making "sustainability" mandatory: and on the other hand to really achieve the climate objectives that would like to eliminate CO2 emissions and the land consumption by 2050, adherence to disciplinary leads to sustainability mindsets cannot be left to the "conscience" of entrepreneurs but should switch from incentivized forms of coercion or negotiation also with the use of already tested tools such as those of collective autonomy.

Assessment of vineyard vigour and yield spatio-temporal variability based on UAV high resolution multispectral images
2023
Accurate, timely assessment of the vineyard on a field scale is essential for successful grape yield and quality. Remote sensing can be an effective and useful monitoring tool, as data from sensors on board Unmanned Aerial Vehicles (UAV) can measure vegetative and reproductive growth and thus directly or indirectly detect variability. Through the images obtained from UAV, the Vegetation Indices (VIs) can be calculated and compared with various agronomic characteristics of the vineyard. The objective of this study was to evaluate the multispectral response of the vineyard in three specific phenological phases and to analyse the spatial distribution of vegetative vigour. A multirotor UAV equi…
