Produzione di semi sintetici di Capparis spinosa (L.). Innovazione e tradizione
2011
The caper bush (Capparis spinosa L.) is a rupiculous species. It is widespread on rocky areas and it grows on different soil associations. Caper can be propagated from fresh seeds, gathered from ripe fruit, or by stem cuttings both methods with unsatisfying results, due to the low germination percentage and to the season-dependent answer of the cutting technique. The aim of the present research has been to evaluate the attitude, for caper in vitro propagules , to be encapsulated. Micro cuttings from in vitro plantlets, were dissected and put on two different Murashige and Skoog liquid media enriched with 4% sodium alginate and 1,4% di CaCl2 separately, for the encapsulation. The synthetic s…

Temperatura e modalità di conferimento del latte al caseificio: effetti sulla carica psicotrofa e non solo
2011
Obiettivo di questo lavoro era lo studio dell´evoluzione della carica microbica totale e psicrotrofa indesiderata nel latte per produzione di Grana Trentino al variare del sistema di raccolta del latte. Il conferimento due volte al giorno del latte raccolto in bidoni senza refrigerazione o in cisterna refrigerata a 18°C è stato confrontato con il conferimento una volta al giorno del latte raffreddato alla stalla a 8 o 12°C. I latti sono stati seguiti dalla stalla alla caldaia, i campioni di latte e panna sono stati analizzati tramite tecniche classiche e molecolari per la definizione del quadro microbico. La composizione microbica del latte intero non differiva nelle 4 tesi: in tutti i camp…
Effect of cold storage on the quality of minimally processed cauliflower
2015
Cauliflower has been described as a vegetable with a high nutritional value due to its important content of vitamins, antioxidants and anti-carcinogenic compounds. Cauliflower inflorescences are harvested while they are totally immature, which implies severe changes in nutrient, water and hormonal status. Harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The effects of processing and cold storage of minimally processed green cauliflower were investigated. Florets were treated with antioxidants before storage in PE bags at 4°C for 21 days. During storage, weight loss, colour, firmness, soluble solids content and p…
Landscape Architecture Design as a Resource in the Regeneration of Sicilian Mining Landscapes
2016
This contribution regards mining landscape in Sicily and its physical dimension. It has been shaped by the stratification of different layers such as topography, geology, vegetation, roads, functions, existing buildings and structures, underground spaces. The purpose of the paper is to understand their relations and their shapes, through a specific case study. We are dealing with a large mining park in the middle of Sicily, characterized by the layering of the various elements previously described.
El mundo vegetal en la mitología clásica y su representación artística
2005
La representación artística de los contenidos de la mitología clásica ofrece innumerables temas de estudio entre los que se encuentra la presencia del mundo vegetal. A partir de las referencias literarias de la Antigüedad, enriquecidas e interpretadas especialmente desde el siglo XVI, el presente artículo explica cómo un buen número de árboles, plantas y flores se convirtieron en atributos de dioses y héroes, bien como símbolo de sus virtudes o de sus actividades.

Identità paesaggistica del centro storico di Modica
2016
Il centro storico di Modica si sviluppa lungo il margine orien- tale dell’Avampaese ibleo, un horst calcareo allungato in senso NE-SW che rappresenta il margine settentrionale della placca africana. Il plateau ibleo è attraversato da numerose faglie va- riamente orientate a costituire un sistema di canyon, localmente denominati “cave”, attraversati da corsi d’acqua alimentati da sorgenti carsiche, uno dei quali è il torrente Modica – Scicli, sulle cui pareti si inerpica il centro storico di Modica.
Intrinsic Viscosity of Aqueous Solutions of Carboxymethyl Guar in the Presence and in the Absence of Salt
2008
Intrinsic viscosities were determined for solutions of CMG in pure water and 0.9 wt.-% aqueous NaCl. To avoid the 0/0-type extrapolation typical for Huggins plots, a new procedure was used. For CMG and pure water, this requires only two adjustable parameters: the specific hydrodynamic volume of the polymer in the limit of infinite dilution and a hydrodynamic interaction parameter. The intrinsic viscosity of CMG (no salt) at room temperature is 6 050 mL · g -1 ; approximately half as large as that of Na-PSS of comparable molar mass. The ratio of the intrinsic viscosities with and without salt is ≈7 for CMG, as compared to >100 for Na-PSS. The reasons for the different behaviors of the two ty…
Morphological and agronomical characterization of eggplant genetic resources from the Sicily area
2013
The eggplant is a vegetable crop widely grown throughout Sicily both in greenhouse and open field. This study was carried out by the Department of Agri-Environmental Systems at the University of Palermo in the Spring/Summer of 2011 in open fields. The aim of the study was to characterize 6 eggplant ecotypes (G1-G6) and three eggplant varieties (Birgah, Black bell and Viola di Firenze) from a morphological, phenological and production point of view, gathered from Sicily and the smaller islands. The genotypes G1 and G3 were found to be more productive than the varieties used in the test field. Ecotype G1 produced fruits which were dark violet and highly glossy, and produced the lowest percent…
The Isoetes longissima complex (Isoetaceae) in Italy: observations on the morphology of spores and leaves, and taxonomic implications
2014
The morphological variability of the Isoetes longissima complex in Italy has been analyzed, on the basis of selected herbarium specimens. Observations were made on spore ornamentation and size, number of leaves per plant and maximum leaf length, velum extension and alae width in the basal portion of leaves. The first count of chromosome number on plants from Italy is also made. On the basis of our observations, the five taxa here considered are attributed to two taxa, treated at the species level as follows: I. longissima (incl. I. velata and I. velata [unranked] sicula), and I. tiguliana (incl. I. dubia). Italian distribution of these species is also given.
