Evaluation of the quality and antioxidant capacity of woodland strawberry biotypes in Sicily

2013

In Sicily, the woodland strawberry grows wild in forest glades in the Madonie and Nebrodi mountains and on Mount Etna. In this region, the main cultivated clone is Fragolina di Ribera, named after the towns where the crop originally developed. The cultivated woodland strawberry is different from its wild counterparts not only in vegetative vigour and size, but also in organoleptic quality. Fragolina di Ribera has always been described with sensory analysis as one of the best Sicilian berry. This study was carried out in Sicily and compared two June-bearing Fragaria vesca: Fragolina di Ribera and Fragolina di Maletto, and an everbearing variety Regina delle Valli, in order to determine the p…

Environmental and genotype effects on the fruits quality and nutritional traits of wood strawberry in Sicily

2012

In Sicily, the common woodland strawberry (Fragaria vesca) is spontaneous in the Madonie Mountains (554 m a.s.l.), Nebrodi Mountains (850 m) and Mount Etna (900 m). In this region, the main clone cultivated is 'Fragolina di Sciacca e Ribera', named after the towns where the crop originally developed. It is a Junebearing genotype and it is characterized by very small fruits, globose-conical shape, deep red colour, very soft flesh, strong aroma and flavor. Also ever-bearing clones are cultivated in Sicily where they are cropped for many months. Solid soluble content, total titratable acidity, total antioxidant capacity, total polyphenols and anthocyanins content were quantified in berry sampl…

Development of “universal” gene-specific markers from Malus spp. cDNA sequences, their mapping and use in synteny studies within Rosaceae

2009

The Rosaceae contains many economically valuable crop genera, including Malus (apple), Fragaria (strawberry), and Prunus (stone fruit). There has been increasing interest in the development of linkage maps for these species, with a view to marker-assisted selection to assist breeding programs and, recently, in the development of transferable markers to permit syntenic comparisons of maps of different rosaceous genera. In this investigation, a set of Malus cDNA sequences were downloaded from the European Molecular Biology Laboratory database. The sequences were aligned with homologous full-length Arabidopsis genomic DNA sequences to identify putative intron–exon junctions and conserved flank…

The aroma of strawberry (Fragaria ananassa): Characterisation of some cultivars and influence of freezing

1990

The volatiles of six strawberry (Fragaria ananassa Duch) cultivars, both fresh and deep-frozen, were isolated by direct dichloromethane extraction. Sixty compounds were identified and quantified by GC—MS. Characterisation of cultivars was achieved by applying principal component analysis to the chromatographic data. Great differences were observed. Maxim and Directeur Paul Wallbaum are rather low in volatiles while Gariguette and Tioga are rich in mesifurane (2,5-dimethyl-4-methoxy-2,3-dihydrofuran-3-one), furaneol' (2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one) and nerolidol. Esters are the major compounds in Senga Sengana and Vicomtesse Hericart de Thury. This last cultivar is also chara…

Study on New Strawberry Varieties Evaluated in Sicily

2009

The variety evolution and growing techniques have modified the strawberry cultivation in the Italian Mediterranean areas. Different trials in Sicily showed that varietal choices are the base to reach high levels of quality and quantity production. In Sicily, 300 ha of strawberries are now cultivated and 'Tudla' is still the principal variety (60%), 'Camarosa' is the most cultivated variety in the other southern strawberry areas, but in Sicily this cultivar does not generate a great interest because of its lateness. New cultivars, such as 'Candonga', 'Ventana' and 'Naiad', have been trialled in the last years but further evaluations are necessary. The trial was carried out at the experimenta…

Monoclonal antibody-based immunoassays for cyprodinil residue analysis in QuEChERS-based fruit extracts

2015

Cyprodinil is among the most common agrochemical residues found in highly perishable fruits, such as strawberries. In the present study, high-affinity monoclonal antibodies to this anilinopyrimidine fungicide were raised for the first time with the aim to produce valuable immunochemical analytical assays. Cyprodinil bioconjugates and the generated novel monoclonal antibodies were employed for sensitive competitive immunoassay development in two different formats. The limits of detection of the optimized assays were 20 and 30 ng L-1 for the indirect and direct assay, respectively. Influence over assay parameters of different physicochemical factors was studied. Strawberry samples were extrac…

Vector Transmission of a Plant-Pathogenic Bacterium in the Arsenophonus Clade Sharing Ecological Traits with Facultative Insect Endosymbionts

2009

Bressan, A., Semetey, O., Arneodo, J., Lherminier, J., and BoudonPadieu, E. 2009. Vector transmission of a plant-pathogenic bacterium in the Arsenophonus clade sharing ecological traits with facultative insect endosymbionts. Phytopathology 99:1289-1296. The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the major vector of a nonculturable plant-pathogenic γ-3 proteobacterium associated with a disease of sugar beet called syndrome “basses richesses” (SBR). The bacterium, here called SBR bacterium, belongs to the Arsenophonous clade, which includes mostly insect-associated facultative symbionts. Assays using field-collected planthopper nymphs and adults were carried out to inve…
