Agronomic Evaluation and Chemical Characterization of Sicilian Salvia sclarea L. Accessions
2020
Clary sage (Salvia sclarea L.), known for its aromatic and medicinal properties, belongs to the Lamiaceae family. Although the species grows wild throughout Sicily, knowledge of its production and qualitative properties is limited. The aim of this study was to evaluate the agronomic behavior of the species over two years of testing and to characterize the chemical properties of its wild counterparts in order to identify the most promising accessions for cropping or for use in breeding programs. Tests were carried out during 2008, 2009, and 2010. During the first year, the plot was established. Subsequently, the main parameters for bio-agronomic evaluation were taken in 2009 and 2010. Regard…
Effects of environment and sowing time on growth and yield of upland cotton (Gossypium hirsutum L.) cultivars in Sicily (Italy)
2020
Cotton is one of the most important industrial crops in the world. Though widely cultivated in Sicily (Italy) in the past, cotton growth on the island has disappeared today due to a complex variety of agronomic, economic and socio-political reasons. In recent years, increased interest in natural fibers worldwide has led to a revival in cotton plants in the Mediterranean area. The aim of this paper was to assess the response of Gossypium hirsutum L. cultivars to different environments and sowing times. Elsa and Juncal were selected from the most promising cotton cultivars regarding earliness and productivity. Plants were tested with three sowing times and in two Sicilian environments. Cotton…
Breeding For Organic Farming : Obtaining And Evaluation Of Flax Somaclonal Families
2015
Plant calli culture could be used as a source of genetic changes (somaclonal variation). There are known several flax varieties, bred on the basis of somaclonal variation, with improved resistance to biotic and abiotic stresses, plant height, seed yield and other traits. This method is useful for obtaining the new initial material for flax breeding, including for intensification of breeding for organic farming. Goal of the study was to obtain plants-regenerants from the calli culture of the fibre flax variety ‘Vega 2’ and to evaluate their agronomical traits and resistance to powdery mildew. For obtaining plants-regenerants was used early elaborated protocol of somatic calli cultivation. Ag…

Phytochemical, ecological and antioxidant evaluation of wild Sicilian thyme: Thymbra capitata (L.) Cav.
2016
In a broad survey conducted throughout the Sicily region, 45 different sites were identified where thyme grows wild. All the biotypes collected were classified as Thymbra capitata (L.) Cav. (syn. Thymus capitatus (L.) Hoffmanns. & Link). Cluster analysis based on the main morphological characteristics of the plant led to the division of the biotypes into 3 major groups. All samples were analyzed for their secondary phytochemical metabolites identified in the extracts and the essential oils. LC-UV-DAD/ESI-MS and GC-FID/GC-MS have been applied to characterize the extracts and the essential oils, respectively. In the extracts, 15 flavonoid derivatives with taxifolin-di-O-glucoside and thymusin…
Agronomic Management of Indigenous Mycorrhizas
2008
Many of the advantages conferred to plants by arbuscular mycorrhiza (AM) are associated to the ability of AM plants to explore a greater volume of soil through the extraradical mycelium. Sieverding (1991) estimates that for each centimetre of colonized root there is an increase of 15 cm3 on the volume of soil explored, this value can increase to 200 cm3 depending on the circumstances. Due to the enhancement of the volume of soil explored and the ability of the extraradical mycelium to absorb and translocate nutrients to the plant, one of the most obvious and important advantages resulting from mycorrhization is the uptake of nutrients. Among of which the ones that have immobilized forms in …
Studi fitochimici e agronomici su Artemisia Arborescens L. (Asteraceae) della flora spontanea siciliana e attività biocida degli oli essenziali

Le varietà di avena per le semine 2013-14.
2013
Nell'areale Nord le produzioni più elevate sono state conseguite dalle varietà più tardive Aveny, Gniady e Teo BD40,insieme alle più precoci Genziana, Bionda e Alcudia. Nelle aree del Centro-sud oltre ad Aveny, Genziana e Gniady, si sono distinte anche Primula e Hamal. Nelle isole si sono differenziate Primula, Alcudia, Genziana, Stella D'oro e Hamel.
Valutazione e caratterizzazione bio-agronomica e qualitativa di popolazioni di avena (Avena sativa L.) di origine siciliana.
2013
Tra i cereali minori l’avena ((Avena sativa L.) costituisce una importante risorsa agronomica e economica per gli areali mediterranei. Infatti, questa specie è caratterizzata da una maggiore rusticità rispetto a cereali maggiori come il grano duro, che le permettono di ben adattarsi ad ambienti di coltivazione collinari marginali delle aree meridionali. L’ampia gamma di destinazione produttiva della specie sia per l’alimentazione umana (granella) che animale (foraggio-granella, pascolo-fieno, pascolo-insilato) la rendono una specie assai interessante per le aziende cerealicolo-zootecniche. Inoltre, tale specie, ha già promosso una interessante attività sia nel settore agro-alimentare e sia …
