Ecologia delle popolazioni lattiche associate alle farine di frumento e studio delle attitudini tecnologiche per la produzione di impasti acidi
2013
Il presente lavoro ha previsto inizialmente l’isolamento, la tipizzazione e l’identificazione dei batteri lattici (BL) presenti in campioni di farine utilizzate per prodotti da forno a lievitazione naturale prelevati presso diversi panifici siciliani. Le conte in piastra dei BL sono state ottenute su tre differenti terreni colturali, generici e specifici. I risultati hanno evidenziato una concentrazione massima di BL di 4.75 Log UFC/g. Tutte le colonie diverse sono state isolate e purificate. Le colture sono state differenziate sulla base delle caratteristiche fenotipiche e dei profili generati mediante la tecnica randomly amplified polymorphic DNA (RAPD)-PCR che ha permesso il riconoscimen…
L’importanza della biodiversità floristica nel vigneto siciliano
2023
La scelta di sistemi colturali ecocompatibili implica il mantenimento di una flora equilibrata, espressione di un’ampia biodiversità sito-specifica. Focus sul progetto siciliano STRA.VI.NA. e in particolare sulla valutazione di applicare protocolli di gestione suolo con inerbimento con specie autoctone: si sta salvaguardando e testando una lista di leguminose isolane atte alla costituzione di cotici erbosi per vigneti resilienti.
Sustainable Weed, Disease and Pest Management in Medicinal and Aromatic Plants
2015
As for all other crops, in MAPs as well, weeds, diseases and pests are important yield-reducing factors, which may severely curtain biomass production and, that is maybe more important, may affect several qualitative aspects of production. Research about this topic is generally lacking, for two main reasons: the first is that MAPs are generally grown on rather limited areas, and the incidence of specific pests and diseases rarely takes a relevance outside rather narrow boundaries. The second reason is that the economical importance of MAPs is much lower than that ascribed to the “major” crops, which the bigger efforts of research are addressed to. In the changing scenario of latter years, h…
Essential oil characteristics of wild Sicilian oregano populations in relation to environmental conditions
2014
A study was carried out on the essential oil of Origanum vulgare ssp. hirtum (Link) Ietswaart taken from thirteen wild populations found in different parts of Sicily, Italy. The aim of the study was to evaluate the relationship that exists between essentials oil extracted from Sicilian wild populations of O. vulgare ssp. hirtum (Link) Ietswaart and various weather/climate and topographic factors in order to provide more information on aspects that influence the production potential of this species. The essential oils from the samples were extracted by hydrodistillation and analyzed by a combination of gas chromatography-flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS); se…
THE EFFECTS OF IRRIGATION WATER AS A FUNCTION OF THE DISTANCE BETWEEN IRRIGATION DRIPPERS IN A TOMATO FIELD.
2014
The growth and the yield of the tomato plant in southern hot-arid areas of Italy, depending on the satisfaction of water needs. The aim is to evaluate the effect of the distance between drippers on the marketable yield of tomatoes because the installation depend mainly on the number of drippers. Were compared 4 dripper intervals: 15, 30, 60 and 90 cm. The results show that the distance between the drippers must be determined according to the hydraulic characteristics of the soil. In soils with a clay matrix characterized by a low infiltration rate, it seems useful to position the drippers at a distance between 60 and 90 cm.
Wastewater management using a pilot-scale horizontal subsurface flow system in Western Sicily (Italy) for irrigation of Paspalum vaginatum Sw. turf
2017
The reuse of treated wastewater represents an attractive prospect for sustainable water management in urban areas. The aim of this study was to evaluate the reuse of treated wastewater from constructed wetland systems for the irrigation of Seashore paspalum turf (Paspalum vaginatum Sw.) and assess the effects of treated wastewater on the soil and turfgrass. The research was carried out in Sicily (Italy) in a pilot-scale horizontal subsurface flow system (HSSF). Seashore paspalum plots were irrigated with freshwater and treated wastewater. In treated wastewater-irrigated plots, we estimated the amounts of nitrogen and potassium, supplied by irrigating with treated wastewater. The productive …
Constructed Wetlands as Sustainable Technology for the Treatment and Reuse of the First-Flush Stormwater in Agriculture—A Case Study in Sicily (Italy)
2020
This paper describes a case study that was carried out on a Sicilian company (Italy) dealing with separate waste collection and recycling of glass. The aims of this study were to evaluate the overall efficiency of a vertical subsurface flow system (VSSFs) constructed wetland (CW) operating for the treatment of first-flush stormwater and the effects of treated wastewater on the morphological and aesthetic characteristics of ornamental pepper and rosemary plants. The system had a total surface area of 46.80 m2 and was planted with common reed and giant reed. Wastewater samples were taken from October 2018 to July 2019 at the CW inlet and outlet for chemical-physical and microbiological charac…
Indagine preliminare sul germoplasma di Capparis spinosa subsp. rupestris (Sm.) Nyman dell'isola di Linosa
2009
Il cappero è un suffrutice presente nella flora spontanea del Mediterraneo. Nelle isole minori della Sicilia, in particolare a Pantelleria, Salina e di recente anche a Linosa, il cappero si è affermato in coltura specializzata, acquistando una certa importanza sia in termini economici, ma anche sociali ed ambientali. Questa produzione, infatti, molto apprezzata dai turisti, ha creato un certo volume di commercio locale, consentendo agli agricoltori di realizzare buoni utili. Le caratteristiche di rusticità, tipiche della specie, lo sviluppo e l’architettura dell’apparato radicale le conferiscono, inoltre, un ruolo rilevante nella prevenzione dei processi di erosione del suolo. L’attività in…
Biodiversità in alcune specie del genere Mentha nel territorio dei Monti Nebrodi (Sicilia N-W).
2008
In Nebrodi Mountains (N-E Sicily), the genus Mentha is represented by an high number of species, in many cases typical of humid and subhumid environments. This work was addressed to investigate about the biomorphological traits of various accessions belonging to 3 Mentha species collected in the Nebrodi highlands, namely 22 accessions of Mentha spicata, 12 of Mentha suaveolens and 13 of Mentha aquatica. Plant material was picked up starting from the early spring 2007, from different sites as in altitude and in pedological and climatic traits, that were distributed over an area of 200.000 ha approx.. Later on, all collected plant individuals were transplanted in a collection field, appositel…
