FRUIT QUALITY EVALUATION OF FOUR LOQUAT CULTIVARS GROWN IN SICILY

2011

Chemical (soluble solids content, titratable acidity, pH), morphological (weight, longitudinal and transversal diameter, thickness of the flesh, number of seeds, peel colour), and sensorial characteristics of four loquat cultivars (‘Algerie’, ‘Claudia’, ‘Nespolone di Trabia’ and ‘Sanfilippara’) from mature, organically-grown trees in Sicily, were analysed. The determinations were carried out by traditional instrumental techniques, by a panel test and by an electronic olfactory system. A panel of 10 trained judges was used to determine intensity of some attributes in the sensory profile of the different cultivars, while the electronic olfactory system was used to identify possible difference…

Towards More Efficient Incentives for Agri-environment Measures in Degraded and Eroded Vineyards

2015

Evaluating the economic damage caused by soil erosion is important. In addition to increasing the awareness of the problem among farmers and policy makers, evaluation of the economic damage caused by erosion can promote the implementation of more sustainable soil management practices. In the present study, we describe a new approach to evaluate incentives for the adoption of agri-environment measure (AEM) in degraded and eroded vineyards. To estimate this incentive, the replacement cost (RC) and the loss of income are calculated when the vineyard is managed with conventional tillage versus a cover crop (AEM). Our findings show that the incentive could range from the loss of income due to AE…

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…

Identifying the threshold of soil water content for the precise irrigation scheduling of a Citrus orchard under subsurface drip irrigation

2019

Proper irrigation scheduling requires the knowledge of the soil-plant-atmosphere system, including the relationships existing between its various components. During the last decade, the monitoring of soil water content (SWC) has been considered a standard way to determine when crops need to be irrigated. However, under drip irrigation systems in which laterals are laid on the soil surface or buried at a certain depth, the gradients of soil water content are rather high and therefore the threshold of SWC below which crop water stress occurs should account for the position of the sensors; the threshold, in fact, depends on the specific crop system, as well as on the relative position of the m…

Miglioramento degli standard qualitativi nel vivaismo olivicolo: i risultati del Progetto OLVIVA

Caratteristiche qualitative dei semi delle varietà ad uva da vino Siciliane

2014

In this study, the phenolic compounds of Sicilian grape seeds were evaluated. Flavan-3-ols content was higher in white and relic than black grape seeds. The greater polyphenol quantity found in white cultivars could be also attributed to lower maturity at harvest. The flavan-3-ols content was linked with seed color. The black cultivar showed the highest degree of seed lignification

Lost in space? Using geo-narratives to interpret land use changes in a rural landscape of inner Sicily

2021

Intercropping landscapes characterised by the presence of certain plant features (i.e. old-century olive trees) are usually considered traditional landscapes, extremely important for their biocultural heritage. Olive agroforestry systems were widespread in the past throughout Sicily. Recent evolution processes involving intensification have switched to olive grove monocultures. Here we present ongoing work on the application of geo-narratives to interpret transformation dynamics of land use practices in a rural landscape of inner Sicily. Based on the assumption that spatial patterns are the expression of transformation processes, where the spatial variation of human activities is a signific…

Le potenzialità della filiera foresta-legno in Sicilia

2022

Dalla seconda metà del secolo scorso il patrimonio forestale della Sicilia è aumentato in termini di superficie. L’aumento recente è stato favorito dai processi di rinaturalizzazione degli ex coltivi e dei pascoli e dalla disponibilità di fondi europei per i rimboschimenti e l’arboricoltura da legno, insieme all’adozione di nuove politiche rivolte alla sostenibilità ambientale. Tuttavia, tale incremento della risorsa nella maggior parte dei casi non è stato un affiancato da uno sviluppo delle politiche e delle azioni mirate a promuovere la gestione forestale, tantomeno la valorizzazione dei prodotti legnosi e non. Tale carenza di politiche efficaci nel contesto italiano, in particolare l’ap…
