Effect of weak magnetic fields on the in vitro propagation of Genista aetnensis (Raf. Ex Biv.) Dc.
2017
Over the years, many studies have emphasized the importance of the magnetic fields (MF), used as a safe alternative choice to improve agricultural production. The induction effect of different magnetic fields varies depending on the species, explants typology, intensity of magnetic field and period of exposure. The aim of the present study was to investigate the application of a continuous magnetic field induction, at different exposure times, as a production enhancement for in vitro culture of Genista aetnensis, an endemic shrub commonly named 'Mount Etna broom'. An in vitro protocol has been settled for the conservation of the species. Plantlets cultured onto a solified Murashige and Skoo…
Conserving plant diversity in Europe: outcomes, criticisms and perspectives of the Habitats Directive application in Italy
2016
Habitat Directive is the core strategy of nature conservation in Europe aiming at halting biodiversity loss. In this study the results of the third Italian assessment regarding the conservation status (CS) of plants listed in the Habitat Directive (Flora of community interest—FCI) was presented. Data was collected from several sources related to plant distribution, population data, habitats and pressures. Following the official European procedure, all parameters were evaluated and combined to give the CS of each taxon in each biogeographical region of presence. A comparison between the recent Italian IUCN and Reporting assessments was performed in order to evaluate the consistency between t…
Plant micro-reserves in Valencia (E. Spain): A model to preserve threatened flora in China?
2017
The Valencian Community (eastern Spain) was the pioneer territory establishing plant micro-reserves (PMRs). Its model to protect small sites for endemic and endangered plants has been exported to several countries around the globe. This paper highlights 1) the role of PMRs to complement the protection provided by large protected areas, 2) how the establishment of PMRs fosters the increase of floristic knowledge, and 3) the fact that continuous monitoring of PMRs also yields new records of endangered species found within the same PMRs. The flexibility of the PMR approach -it can be adapted to other national and regional legislations- allows its transfer to other rich-biodiversity regions and…
Nomenclatural synopsis of cirsium sect. Eriolepis (asteraceae) in Italy
2021
The names of the Italian taxa in Cirsium sect. Eriolepis are discussed. The accepted names are: Cirsium echinatum, C. eriophorum subsp. eriophorum, C. eriophorum subsp. spathulatum, C. ferox, C. italicum, C. lacaitae, C. lobelii, C. morisianum, C. scabrum, C. tenoreanum, C. vallis-demonii subsp. vallis-demonii, C. vallis-demonii subsp. calabrum comb. nov., and C. vulgare (= C. crinitum, C. sylvaticum). Four accepted names are typified by specimens preserved at FI (one lectotype), G (one lectotype and one neotype), P (one lectotype), and by illustrations (two lectotypes). Several other heterotypic synonyms of taxa described from Italy are discussed and six of them are typified. A new combina…
Chorological notes on the Sicilian endemic Euphorbia papillaris (Euphorbiaceae)
2022
Thanks to the discovery of a new important site in the Trapani Mountains, the distribution of Euphorbia papillaris, a rare plant endemic to N-W Sicily, is revised. On the basis of the unpublished record, one of the two hypotheses on the discovery of the species in Sicily, previously advanced, is here confirmed. Floristic and ecological information on the new locality are also provided.
Autecology and ex situ growth of Leontopodium nivale subsp. nivale (Asteraceae) from North Pirin marbles (SW Bulgaria)
2018
Kozuharova, E., Panayotov, M. & Spadaro, V.: Autecology and ex situ growth of Leontopodium nivale subsp. nivale (Asteraceae) from North Pirin marbles (SW Bulgaria). — Fl. Medit. 28: 187-206. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. Leontopodium nivale subsp. nivale is a local and disjunct endemic of the central Apennines in Italy and the Pirin Mountains in Bulgaria. The aim of this study is to investigate in situ microhabitat specifics and ex situ ontogenesis regarding the possible future cultivation and to evaluate hazards for wild populations in conditions of human impact and climate change. Leontopodium nivale subsp. nivale is stenobiont which is difficult to grow ex situ and t…
From ethnobotany to experimental research: the therapeutic properties of Sicilian hellebore
2018
In Sicily, the genus Helleborus (Ranuculaceae) is only represented by H. bocconei subsp. siculus (= H. bocconei subsp. intermedius). In some mountain areas of the Island, the rhizomes of this plant, harvested in a particular month of the year (May) and dried, are used in traditional veterinary practice for treating pneumonia in domestic animals, cattle and horses in particular. The same usage – with rhizomes of other Helleborus species or subspecies – is reported from various other areas of Mediterranean Europe. Phytochemical tests have permitted the isolation and characterization of new biologically active molecules. The extracts of rhizomes and aerial parts of the plant were shown antibac…

2019
Euphorbia species were widely used in traditional medicines for the treatment of several diseases. From the aerial parts of Egyptian endemic plant, Euphorbia sanctae-catharinae, three new premyrsinane diterpenoids, namely, euphosantianane E&ndash
Physiological,anatomical and biomass partitioning responses to ozone in the Mediterranean endemic plant Lamottea dianae
2011
Ozone effects on the perennial forb Lamottea dianae were studied in an open-top chamber experiment. Ozone was found to induce reductions in CO 2 assimilation and water use efficiency in the leaves of this species. These reductions were mainly related to a decline in the in vivo CO 2 fixation capacity of Rubisco (V c,max), rather than to stomatal limitations or photoinhibitory damage (F v:F m). In addition to chloroplast degeneration, other observed effects were callose accumulation, formation of pectinaceous wart-like cell wall exudates and phloem alterations. Moreover, ozone exposure significantly reduced root dry biomass. The possible relevance of these adverse effects for Mediterranean f…
