Genetic diversity on Pyrus L. (Rosaceae) in Sicily

2009

The genetic diversity on six Pyrus species (P. amygdaliformis, P. pyraster, P. communis, P. vallis- demonis, P. sicanorum, P. castribonensis) from Sicily was investigated using isozymes. Atotal of 26 alleles was found in 8 loci of 5 enzyme systems (IDH,MDH, 6-PGD, PGI and SKD). The allelic frequencies and the genetic variability values for each population were calculated. The greatest rate of polymorphism was found in P. sicanorum, P. castribonensis and P. amygdaliformis from Sicani Mts. The relationships among the populations were computed by Nei’s genetic identity/distance and the obtained dendrogram shows a remarkable genetic distance of P. vallis-demonis from of all other investigated t…

Aggiornamenti e novità sulle conoscenze di Pancratium maritimum (Amaryllidaceae)

2014

Pancratium maritimum L., bulbosa perenne degli ambienti dunali costieri, è un taxon relativamente recente se comparato con le specie del genere a gravitazione mediterranea. Gli studi noti su questa specie hanno analizzato vari aspetti della biologia (riproduttivi, biochimici, filogenetici, genetici, ecc.). Tuttavia, esistono ancora lacune scientifiche, tra cui l’assenza di studi su ampio areale di genetica di conservazione e sugli adattamenti eco-morfofisiologici alle condizioni di stress. Per ampliare le conoscenze su P. maritimum, la Fondazione Nando Peretti nel novembre 2012 ha finanziato un progetto triennale sulla conoscenza e la salvaguardia di questa specie (Progetto 2012-83). In que…

As activities of the project "Preservation of Abies nebrodensis and restore of Geraci Siculo peatlands", the chemical composition of essential oils, obtained from leaves of Madonie fir, was compared with the ones of essential oils derived from Eurasian species studied up to now

CONTRIBUTION TO THE KNOWLEDGE OF THE TRADITIONAL USES OF NATIVE PLANTS IN SICILY

2016

The Sicilian territory as a whole presents orographic, geopedological, hydrographic characters and climate conditions that determine a wide diversity of environments that host a rich vascular flora consisting of over 3250 specific and intraspecific taxa (subspecies, varieties and forms), belonging to 880 genera of 134 botanical families (1). Of the above mentioned flora, about 500 entities are endemic and in several cases their populations are constituted by a small number of individuals and / or distributed on limited areas. Within this great biodiversity, which places Sicily among the regions with greater floristic diversity of both Italy and the Mediterranean area, it is noteworthy that …
