Genetic Characterization of Tunisian Olive Table Cultivars (Olea europaea L.): Inventory Based on Microsatellite Analysis
2010
Olive (Olea europaea L.) is an ancient crop which spread from the Middle East towards the westem Mediterranean region. In addition lo its agronomical and economical importance, the olive industry has a great social and cultural interest as part of our heritage. In order to characterize and to study the genetic relationship among cultivars, five polymorphic microsatellite loci were used in this study and were generated a total of 56 polymorphic alleles with an average of 11 alleles by locus. For all genotypes, the highest number of polymorphic alleles was obtained by the locus UD0043 and GAPU 103. The polymorphism index content ranged from 0.836 for the locus ssrOeUADCA-04 and 0.919 for the …
Le pesche di Leonforte, tradizione e apprezzamento dei mercati
2018
Il rilevante potenziale genetico della pesca origina in Sicilia un notevole patrimonio varietale con cicli fenologici idonei a creare epoche di maturazione dei frutti la cui durata si prolunga fino all’autunno. Tale diversità dei cicli fenologici, legata alla presenza in Sicilia di un bioclima caratterizzato da 6 differenti termotipi e 7 ombrotipi che originano 23 tipi bioclimatici, ha ben presto messo in luce le caratteristiche vocazionali di specifici areali produttivi. In particolare, negli areali interni e collinari, ad altitudine compresa tra 300 e 750 m s.l.m., si è affermata la produzione di frutti in epoca medio-tardiva basata su varietà di tipo tradizionale, a polpa bianca o gialla…
Effetti di intensità ed epoche di defogliazione sui parametri vegeto-produttivi e sulla qualità dell'uva della cv Nero d'Avola
2014
The trial was carried out over the seasons 2012-2013. A defoliation in prebloom, fruitset and veraison phenological stages was performed and several vegetative, productive and qualitative parameters were assessed. Prebloom and fruitset defoliation resulted in a strong vegetative regrowth and in a reduction of cluster compactness and berry weight. Sugar content at harvest showed significant differences depending on the meteorological condition of the season. Anthocyanins and flavonoids synthesis was favored by leaf removal practice in the coldest season; vice versa in the hottest season the highest bunch exposure in defoliated treatments determined extreme berry temperature and an intense de…
progettazione e impianto dell'oliveto
2011
The establishment of new olive orchards represents the main way to renovate the olive sector in Italy, because they allow high yields and mechanization of cultural practices, particularly harvesting. The design of an olive orchard implies several important choices (area, cultivar, training system, planting density, orientation of the rows, type of trees) which must be made in relation to several factors, such as farm size, type of product that the grower wants to obtain (commercial target), system to mechanize harvesting, kind of cultivation (conventional, integrated or organic). The application of correct techniques for the preparation of the site, disposal of excessive water, execution of…
Identification of aroma compounds of Vitis vinifera L. flowers by SPME GC-MS analysis
2015
Using a gas chromatographic method (GC-MSanalysis), it was possible to determine the volatile constituent of an odorous flower from Vitis vinifera varieties growing in Sicily. More than 50 compounds were identified and the technique allowed us to determine that sesquiterpenes, as well as monoterpenes such as limonene and cymene, were the principal components. The odour-profiles allowed us to distinguish between variety groups or even single varieties.
