The conservation of the endemic Crop Wild Relatives in the RIBES seed-banks: towards a national priority list for the Italian CWRs

2016

Data of 620 crop wild relatives of species of food and fodder interest listed in the Annex I of the FAO Treaty (FAO, 2001) were collected within the census carried out by ISPRA, the Italian National Institute for Environmental Protection and Research, in 2014-2015 in order to quantify the extent of CWR representation in the Italian ex situ collections. According to such census, the RIBES network preserve 37% of the Italian CWRs listed in the FAO Treaty: in 14 out of 16 seed-banks are preserved 6,029 accessions of 229 CWR taxa, belonging to 11 families and 57 genera.

Contributo alla conoscenza degli effetti dell'inquinamneto atmosferico su foglie di Eucalyptus camaldulensis ed E. Globulus (Myrtaceae)

Contribution to the knowledge of air pollution effects on Eucalyptus camaldulensis and E. globulus (Myrtaceae) leaves -.This study deals with the metal storage found in Eucalyptus camaldulensis and E. globulus leaf structures. The cytological and chemical analysis were carried out on samples from the city of Agrigento and its surroundings. The investigation pointed out that the the most evident alterations are phenolic storage and distinctive cellular modification. These features appear related to the greater presence of trace elements within the sites that are more exposed to intense vehicular traffic. Winter samples, moreover, have more evident structural modifications due to a bigger con…

Seed germination in Abies nebrodensis (Pinaceae)

2019

Abies nebrodensis is a strict Sicilian endemic species, listed as “Critically Endangered” in the IUCN Red List of Threatened Species. Seed production highly varies annually and among specimens. The species is affected by a very low seed germination rate, mainly depending on the large number of empty seeds (from 68 to 96%). The embryo presence in seeds increases with increasing seed size and weight. Optimal germination rate (61%) was achieved at constant 5°C in the darkness. The low proportion of embryos in seeds is a relevant threat for A. nebrodensis conservation, as it affects the intrapopulation genetic diversity and reduces the potential genetic variability of seed accessions preserved …

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…

Development of Sicilian bean core collection using morphological descriptors

2018

Different species and varieties of bean, spread in Sicily, are representative of local agricultural practices, as result of a careful exploration. Many landraces have become obsolete due to the spread of commercial varieties, but are still cultivated in small areas of Nebrodi Mountains (ME-Italy) and are endangered. The Sicilian bean landraces are often poorly known but represent a genetic heritage to be preserve and to enhance. The ex situ conservation of Sicilian bean landraces was carried out in “Living Plants Germplasm Bank” of Ucria (ME-Italy), founded by the Nebrodi Regional Park, and in “Sicilian Plant Germplasm Repository” of STEBICEF Department - University of Palermo. Within ex si…
