Non-chemical weeds management in two Mediterranean culinary herbs
2009
Weeds management is one of the most relevant constraints to the cultivation of Medicinal and Aromatic Plants, especially when they’re cultivated with “organic” methods, that, according to EU regulations, do not allow the use of chemicals. A strong interest is therefore devoted to pointing out “alternative” (agronomical and physical) methods for weeds control. This work reports the results of a trial performed in 2003-04 and 2004-05 in order to evaluate the effects on Coriander (Coriandrum sativum L.) and Fennel (Foeniculum vulgare Mill.) of four non-chemical methods for weeds control: FS (False seeding), PD (Flaming), MZ (Mechanical weeding), SM (Hand weeding) compared with two untreated co…
Wild Sicilian Rosemary: Phytochemical and Morphological Screening and Antioxidant Activity Evaluation of Extracts and Essential Oils
2015
To identify the best biotypes, an extensive survey of Sicilian wild rosemary was carried out by collecting 57 samples from various sites, followed by taxonomic characterization from an agronomic perspective. All the biotypes collected were classified as Rosmarinus officinalis L. A cluster analysis based on the morphological characteristics of the plants allowed the division of the biotypes into seven main groups, although the characteristics examined were found to be highly similar and not area-dependent. Moreover, all samples were analyzed for their phytochemical content, applying an extraction protocol to obtain the nonvolatile components and hydrodistillation to collect the essential oil…
PAESAGGI AGRICOLI TRADIZIONALI E CAMBIAMENTI CLIMATICI: INSEGNAMENTI DALL’ISOLA DI PANTELLERIA
Il paesaggio di Pantelleria è fortemente determinato dai fattori geografici e ambientali ma anche dalle modifiche apportate dagli agricoltori per rendere coltivabile l’isola. Gli elementi peculiari di questo paesaggio agrario sono il frutto della necessità di tesaurizzare l’acqua. Anche le tecniche agronomiche (scelta delle specie, forme di allevamento, …) sono finalizzate a consentire la coltivazione in un’area dove la piovosità è ridotta e la ventosità costante. Un aumento della temperatura avrebbe probabilmente effetti pesanti su questo antico ma precario equilibrio. Landscape of Pantelleria is determined from the geographic and environmental factors but also from the modifications broug…
Biomolecular characterization of wild sicilian oregano: phytochemical screening of essential oils and extracts, and evaluation of their antioxidant a…
2013
An extensive survey of wild Sicilian oregano was made. A total of 57 samples were collected from various sites, followed by taxonomic characterization from an agronomic perspective. Based on morphological and production characteristics obtained from the 57 samples, cluster analysis was used to divide the samples into homogeneous groups, to identify the best biotypes. All samples were analyzed for their phytochemical content, applying a cascade-extraction protocol and hydrodistillation, to obtain the non volatile components and the essential oils, respectively. The extracts contained thirteen polyphenol derivatives, i.e., four flavanones, seven flavones, and two organic acids. Their qualitat…
VALUTAZIONI DELLE POTENZIALITA’ AGRONOMICHE, ORNAMENTALI E MORFO-FUNZIONALI DI ALCUNE SPECIE RUPICOLE DELLA FLORA SICILIANA

Influence of arbuscular mycorrhizae on biomass production and nitrogen fixation of berseem clover plants subjected to water stress.
2014
Several studies, performed mainly in pots, have shown that arbuscular mycorrhizal symbiosis can mitigate the negative effects of water stress on plant growth. No information is available about the effects of arbuscular mycorrhizal symbiosis on berseem clover growth and nitrogen (N) fixation under conditions of water shortage. A field experiment was conducted in a hilly area of inner Sicily, Italy, to determine whether symbiosis with AM fungi can mitigate the detrimental effects of drought stress (which in the Mediterranean often occurs during the late period of the growing season) on forage yield and symbiotic N2 fixation of berseem clover. Soil was either left under water stress (i.e., rai…
Moscato Cerletti, a rediscovered aromatic cultivar with oenological potential in warm and dry areas
2021
Baron Antonio Mendola was devoted to the study of grapevine, applying ampelography and dabbling in crosses between cultivars in order to select new ones, of which Moscato Cerletti, obtained in 1869, was the most interesting. Grillo, one of the most important white cultivars in Sicily, was ascertained to be an offspring of Catarratto Comune and Zibibbo, the same parents which Mendola claimed he used to obtain Moscato Cerletti. Thus the hypothesis of synonymy between Moscato Cerletti and Grillo or the same parentage for both sets of parents needs to be verified.In the present study, historical documents were consulted and genetic analyses and ampelographic, agronomic and qualitative character…
