The use of vineyard spectral signatures to identify table grape cultivars
2021
Vineyards have characteristic responses to sunlight. The reflectance values at the different wavelengths are typical of vegetation and define its spectral signature. The aim of this work was to determine the spectral signatures of table grape vineyards located in the production area of Robinvale (Victoria, Australia) in order to identify cultivars in the vineyard. Spectral signatures were detected from images in eight bands from the Worldview 3 platform. Spectral signatures for a representative number of plots were extracted using satellite reflectance images for each cultivar. Spectral signatures were also collected in the field, from the same cultivars, with a FieldSpec® HandHeld 2 portab…

Il settore dell’olivicoltura da tavola in Italia: Situazione e prospettive
2020
Table olive Industry in Italy The Italian table olive industry is almost completely located in the southern regions: Sicily and Apulia together account for about two thirds of the entire national production. “Nocellara del Belice”, “Nocellara etnea”, “Bella di Cerignola”, “Ascolana” and “Itrana” are the leading cultivars, together with a large number of other local traditional varieties, often utilised for a double purpose (table olives and oil production). Although Italy is nowadays largely dependent (more than 50%) on importations from other countries (mainly Spain, Greece and Morocco) the domestic production has been declining in the last thirty years and currently accounts for about 2-3…
Postharvest Application of Sulphur Dioxide Fumigation to Improve Quality and Storage Ability of "Red Globe" Grape Cultivar During Long Cold Storage
2017
Table grape cv 'Red Globe' is produced in Sicily and in other areas of Southern Italy. This produce is very appreciated by consumers, having the best rankings in the world market for exports and quality. Nevertheless, despite it is a non-climacteric fruit, table grape is very perishable, both after harvest, and during postharvest handling and cold storage. In fact, also at low temperatures, table grape is very sensitive to fungal infection (Botrytis cinerea) and other diseases, like gray mold, which is very aggressive. For this reason, a standard practice is to fumigate table grape with sulphur dioxide (SO2), after storage in chambers. The growing market request of table grape cv. 'Red Glob…
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…
Compression tests of cv. Nocellara del Belice table olives for texture evaluation during storage
2014
The influence of pasteurization temperature and time of treatment on the flesh firmness and the evolution of microbial communities was studied for table olives Cv. Nocellara del Belice, packed in glass jars and processed with a tunnel pasteurizer. Pasteurization at industrial scale was carried out within a tunnel pasteurizer applying the treatment at 75 °C for 8 min in the thermal center of the jars. Besides flesh firmness and microbial evolutions, pH, total ti-tratable acidity (TTA) and colour were evaluated for the table olives during storage at 6, 12 and 15 months from packing. Table olives showed a high stability and an acceptable flesh firmness for the entire period under observation. …
Study on the tunnel pasteurizer in table olives processing
2014
The application of heat treatment is especially important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. However, heat treatments can be cause of deterioration of many quality parameters of agro-food products including texture, intended as the consistency of the pulp. Pasteurization is one of the most important steps of the table olives packaging process; it is applied after that olives are properly treated for debittering process. In this study ‘Nocellara del Belice’ table olives produced in 2010 and packaged in glass jars, were subjected to pasteurization at industrial scale…
Strategie di controllo di Bactrocera oleae (Rossi) nell’olivicoltura biologica da olio e da tavola.
2010
I buoni risultati ottenuti nell’olivicoltura biologica da olio sono legati alla raccolta anticipata che limita le infestazioni tardive di Bactrocera oleae (Rossi) e gli effetti negativi delle infestazioni in atto. Molto utilizzate per il controllo della mosca sono le catture massali. L’infestazione dannosa registrata nei due mesi precedenti la raccolta risulta strettamente correlata alla qualità dell’olio, mentre non lo è l’infestazione totale alla raccolta. Gli insetticidi consentiti nell’olivicoltura biologica sono molto poco utilizzati. Nelle situazioni di forte pressione della mosca soltanto i trattamenti con argille e prodotti del rame riescono a mantenere bassi i livelli d’infestazion…
Investigating the ecology of Chara cf. baltica (Characeae) in the Lago Preola ecosystem (Sicily, Italy)
2018
Lago Preola is a small lake, located in SW Sicily, in a karstic depression within the Nature Reserve “Lago Preola e Gorghi Tondi”. With about 33 ha (maximum depth: 2 m), it is the widest of the 5 natural lakes occurring in the Reserve. The presence of species of conservation concern (e.g., Emys trinacris, the Sicilian Pond Turtle, and several migratory birds), but also of invasive alien species (e.g., Procambarus clarckii, the Red Swamp Crayfish), has been reported for the area. The flora of terrestrial habitats surrounding the basins has been studied extensively, while the aquatic flora and vegetation have not been studied in detail. The coastal aquifer supplying groundwater to the study a…
