Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces
2021
Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…
Computerized image analysis applied to inspection of vetch seeds for varietal identification
2011
Vicia sativa L. is an annual cleaning crop mainly used in rotation with durum wheat, both for seed production and for forage, either as a pure crop or as an undercrop, and is well adapted to the hot-dry climate and poor soils of Southern of Italy. Generally, cultivar identification is done on the basis of distinctive traits, such as shape, size, colour of the testa and ornamentations, identified during the variety registration, following official protocols. For some vetch varieties seed identification by specialized technicians is possible without difficulty, while for other varieties it is very difficult and sometimes impossible to achieve undoubted identification. Therefore, it is importa…
RESPONSE OF MELON GENOTYPES TO POLYETHYLENE AND BIODEGRADABLE STARCH-BASED MULCHING FILMS USED FOR FRUIT PRODUCTION IN THE WESTERN COAST OF SICILY

Influence of grain quality, semolinas and baker’s yeast on bread made from old landraces and modern genotypes of Sicilian durum wheat
2021
Abstract Several studies showed that products made with ancient wheat genotypes have beneficial health properties compared to those obtained with modern wheat varieties, even though the mechanisms responsible for the positive effects are not clear. Ancient durum wheat genotypes are being currently used for the production of pasta, bread and other typical bakery products but the consumption is strictly local. In this work 15 genotypes of Triticum turgidum subsp. durum, including 10 ancient and 5 modern, were characterized for their technological traits through the determination of different parameters: protein content, dry gluten, gluten index, yellow index, ash, P/L, W and G. In addition, t…
Genetic variation of an Italian long shelf-life tomato (Solanum lycopersicon L.) collection by using SSR and morphological fruit traits
2014
The recovery of ancient germplasm in tomato (Solanum lycopersicon L.) has become necessary to limit the wide genetic erosion caused by the employment of modern cultivars. Among germplasm collections, long shelf-life landraces could represent an important source of biodiversity. The present study provides a first set of molecular and phenotypic data on long shelf-life (so called "da serbo" in southern Italy) tomato collection, mainly originated from Sicily together with some landraces from Campania and Apulia. The analysis of fruit traits showed a low intra-varietal variation, while exhibiting a quite higher inter-varietal variability. Overall, the cultivars have been classified in six fruit…
Economical Issues Regarding the Implementation and Functioning of the Common Catalogue of Varieties of Agricultural Plant Species
2013
Abstract Economical constraints regarding the full implementation and functioning of the common catalogue on plant genetic resources for food and agriculture (PGEFA) are discussed in this paper based on the assessment of the current European Union regulatory framework. Based on this article's results new financial mechanisms should be developed at the national level for further responding to the European requirements including measures regarding the conservation varieties. This assessment is further supporting the need for developing and implementing new financial mechanisms in the support of the poor rural populations as well as for small farmers in harmony with commercial agriculture.
Study and characterization of polyphenol oxidase from eggplant (Solanum melongena L.)
2011
ABSTRACT: In this study the catecholase and cresolase activities of eggplant polyphenol oxidase (PPO) were investigated. Enzyme activity was determined by measuring the increase in absorbance using catechol as substrate and 3-methyl-2- benzothiazolinone hydrazone (MBTH) as coupled reagent. The effects of substrate specificity, heat inactivation, temperature, pH, and inhibitors were investigated to understand the enzymatic alteration of ready-to-eat preparations. Browning of vegetables was determined through a colorimeter. Decrease of lightness (L*) and increase of color difference values (ΔE*) were correlated with tissue browning. Antibrowning agents were tested on PPO under the same condit…
Valutazione produttive e qualitative di Timilie - Produttive and qualitative evaluation of timilie
2009
Riassunto: Gli autori riportano i primi risultati produttivi e qualitativi relativi a 4 popolazioni di timilie raccolte in diversi ambienti pedoclimatici della Sicilia occidentale. Attraverso uno schema sperimentale non ripetuto sono state valutate 720 accessioni ed è emersa una elevata variabilità tra e intra popolazioni. Dalle analisi qualitative delle accessioni collezionate sono emerse peculiari caratteristiche qualitative della granella che ne fanno intravedere l’uso sia per la produzione di prodotti tipici sia per il trasferimento in varietà ampiamente diffuse e coltivate. Abstract: Productive and qualitative results on four “timilia” population from different West Sicilian pedoclimat…
Epoche d'impianto e sistemi di allevamento per il fagiolo "Badda"
2010
The bean landrace"Badda" has been cultivated since long ago in the Madonie mountains in the northern side of Sicily.It is characterized by a bush indeterminate habit and comprises two ecoty termed 'Badda bianca ' and 'Badda nera' according to the seed colour. This paper describes the results of a study on the effects of four sowing dates (June 15 and 30, July 15 and 30) and two vertical training sustems 8a frame of Arundo donax dry canes or a trellis consisting of several strands of wire) on productivity of the phaseolus landrace 'Badda bianca'. Marketable yields obtained from 15 june sowing were significantly higher than those from June 30 and July 15 sowing dates which in turn were signif…
