Valutazione degli effetti della legge di riordino del Servizio Sanitario Regionale siciliano su efficienza e appropriatezza delle prestazioni ospedal…
2014
La Legge Regionale n. 5 del 14 aprile 2009 segna un punto di svolta nel processo di riforme che ha interessato il Servizio Sanitario della Regione Siciliana, introducendo, tra l’altro, interventi mirati alla razionalizzazione della rete ospedaliera. Obiettivo del presente lavoro è valutare gli effetti della riforma sulla produzione dei servizi ospedalieri in termini di efficienza e di appropriatezza. L’ipotesi da verificare è se il mutamento del quadro normativo, entro il quale si sono trovati ad operare gli ospedali pubblici e privati accreditati, ha reso possibile il raggiungimento degli obiettivi prestabiliti di efficienza, di riduzione degli sprechi nell’utilizzo delle risorse e miglior…
Genetic Diversity of Major Olive Varieties from Southern Tunisia
2013
Considering the importance of olive-growing in Tunisia, microsatellite (SSR) analysis was used to study the genetic variation among twenty olive accessions from southern Tunisia. This set of olive microsatellites showed potential utility for genetic studies and it could contribute to the development of strategies for Tunisian germplasm conservation and breeding. Unweighted pair group method cluster analysis was performed and cultivars separated in three main groups. Five polymorphic simple sequence repeats (SSR) loci were employed and they revealed 38 alleles with a mean number of 7.6 alleles per locus. Genetic variability was wide as indicated by high values of both observed heterozygosity…
INTRA-CULTIVAR DIVERSITY IN SOUTHERN ITALY OLIVE CULTIVARS DEPICTED BY MORPHOLOGICAL TRAITS AND SSR MARKERS
2014
In this study, SSR analysis was performed on a large number of putative clones of the main olive cultivars from two Italian regions, Sicily and Calabria, in order to study the genetic relatedness, and to detect any degree of genetic diversity, which can be used to unambiguously identify possible superior clones. These putative clones have been collected and observed in the last ten years, following an extensive investigation carried out in traditional olive growing areas, thanks to the reports of farmers, millers, technician, growers and nurseries. The set of microsatellite (SSR) markers used allowed the detection of the genetic diversity, resulting from somatic mutation, indicating the pre…
Intra-cultivar Diversity in sicilian and calabrian olive (olea europaea L.) Cultivars Depicted by Morphological Traits and SSR Markers

Genetic and morphologic diversity of European fan palm (Chamaerops humilisL.) populations from different environments from Sicily
2014
Chamaerops humilis is decreasing in abundance in Mediterranean Europe, which has induced the European community to call for its protection in Special Areas of Conservation. However, information about its genetic and morphological variability, which is crucial to the development of any conservation strategies, is insufficient. The present study aimed to investigate the genetic and morphological variability of C. humilis in Sicily, which was selected as a model because of the high number of dense populations. The relationships between morphological traits and climatic variables were studied to highlight patterns of adaptation to the environment, along with the genetic similarity among the pop…

Is It Possible to Produce Certified Hazelnut Plant Material in Sicily? Identification and Recovery of Nebrodi Genetic Resources, in vitro Establishme…
2021
Eight Sicilian cultivars of hazelnut (Corylus avellanaL.), namely-Curcia, Nociara Collica, Panottara Collica, Panottara Galati Grande, Parrinara, Panottara Baratta Piccola, Enzo, and Rossa Galvagno, registered into the Italian Cultivar Register of fruit tree species in 2017 were selected from Nebrodi area and establishedin vitro. The aim of the work was to carry out the sanitation of the cultivars and get virus-free plants from the most important viral pathogen threat, theapple mosaic virus. Virus-free plant material is essential for the production of certified plants from Sicilian hazelnut cultivars, complying the CE (cat. CAC) quality and the technical standards established in 2017 for vo…
