Comportamento agronomico di quattro nuovi portinnesti ibridi pesco x mandorlo in un impianto ad alta densità in Sicilia
2009
The present study was aimed to evaluate the agronomic behavior of different rootstocks, recently licensed by the Dipartimento di Coltura e Difesa delle Specie Legnose of the University of Pisa, and tested in a high density planting system (2220 trees/ha). Trials were carried out in an experimental orchard established by the Dipartimento di Colture Arboree of the University of Palermo and located in Sicily (Sciacca – Agrigento – 150 m a.s.l.). The observations were carried out on clonal rootstocks: I.S. 5/8 (Polluce); I.S. 5/19 (Castore); I.S. 5/23; I.S. 5/29 and GF 677 grafted at dormant bud with the low chill requirement cultivar “Tropic Snow”. The orchard was established in 2004, trees we…
Impeachment: a citizen’s guide
2019
For a scholar with a strong interest in political ‘ruptures’ and contingencies, Cass R Sunstein’s new book Impeachment: a citizen’s guide covers important themes of maintaining constitutional order...
Rootstock and fruit canopy position affect peach [Prunus persica (L.) Batsch] (cv. Rich May) plant productivity and fruit sensorial and nutritional q…
2013
The right combination of rootstock and training system is important for increased yield and fruit sensorial and nutritional homogeneity and quality with peach [Prunus persica (L.) Batsch]. We investigated the effects of rootstock and training system on these parameters, testing the effect of vigorous GF677 and weaker Penta - rootstock on 'Rich May' peach cultivar. Fruit position effects regarding photosynthetically active radiation availability, along the canopy profile using the Y training system, were investigated. The positive relationships between total polyphenols content and antioxidant capacity according to canopy vigour and architecture were determined for the two scion/stock combin…
Elections, Referendums and Parties
2015
By the end of 2014, the Baltic states had held a total of 19 parliamentary, 19 municipal and 3 cycles of European Parliament elections. Lithuania, which elects its president via a national popular vote, had additionally held six presidential polls. Another 23 referendums have been held since August 1991. The rigidity of the Lithuanian and Latvian electoral and judicial institutions have been tested by the 2004 impeachment of Lithuanian president, Rolandas Paksas, and the subsequent early presidential election, as well as a referendum on the recall of Latvia’s parliament in the summer of 2011 and the following early election. Estonia is recognised as an electoral innovator, being the first s…
Image et parole : le vitrail de Saint Lubin à Chartres : sens et fonction de ses images à la fin du XIIe siècle
2019
The enigma of saint Lubin stained glass window at Chartres, showing a wine story in the middle of the saint’s life, can be resolved by a symbolic interpretation of it’s images, if paying regard to the medieval mental schemes : the central Eucharistic mystery of the wine enables the young Lubin to achieve sainthood, through his own vocation of consecrated (the learned canon of XIIth century appearing under the VIth century monk), priest and bishop, Good Sheperd dispensing divine gifts. The unusual presence of small human figures at the outer framework of the stained glass window emphasises the important role to be played by the laity in the Eucharistic mysteries. It takes part, with the intr…
The Sicilian peach (Prunus persica L. Batsch) germplasm: Evaluation of genetic diversity using SSRs
2006
The decrease in worldwide consumption of peaches due to the poor flavour quality of the fruit has increased the demand for new tasty cultivars. The availability of plant genetic resources is an important prerequisite for improving fruit quality by breeding. In Sicily there is a large collection of local cultivated peaches, whose production fills a niche in the local markets, but which is at risk of disappearing. Their characteristics include highly aromatic fruit and late ripening. Because of their important agronomic characteristics, the Department of Colture Arboree of Palermo University has collected the most interesting accessions to safeguard them and to use the indigenous resources in…
CHANGES IN ASCORBIC ACID CONTENT IN FRESH CUT SICILIAN YELLOW-FLESH PEACHES
2015
The traditional yellow-flesh peach cultivars 'Settembrina' and 'Ottobrina' di Leonforte ripen respectively during the first 10 days of September, and the first 10 days of November, in Sicily, Italy. During pit hardening, fruit are covered with a paper bag in order to protect them from Mediterranean fruit fly. To understand their behaviour in terms of postharvest maintenance and suitability for minimal processing, 'Settembrina' and 'Ottobrina' di Leonforte were processed (i.e., cleaned, washed, peeled, cut, dipped and packed) to obtain fresh-cut peaches. Fresh cut slices were stored in perforated or bi-oriented polystyrene bags, after soaking in either a 2% ascorbic acid and 1% calcium lacta…
Propagation techniques and nursery management for the production of certified peach plants in Europe
2022
The propagation of fruit trees, particularly peaches, nectarines and canning clingstone, has reached highly specialized levels since the 1960s. Over the years, the classic seed rootstocks have been replaced by numerous rootstocks produced in vitro, expanding the range of technical solutions for the different soil and climatic growing conditions of several areas. Thanks to the new genotypes from international breeding programs, it was thus possible to renew the cultivated varietal platform several times. Propagation techniques have also undergone an evolution, adopting solutions aimed at shortening nurseries’ production cycles by using June budding or micrografting. Finally, there are differ…
Effect of mucilage edible coating on fresh-cut nectarine cultivar ‘Big Bang’
2022
The mucilage (OFI) obtained from cladodes of cactus pear (Opuntia ficus-indica) is useful to produce natural edible coatings to improve the shelf life of fruits. Edible coatings could be used to extend the shelf life of fresh-cut for products. The aim of this study was to evaluate the effect of (OFI) on quality of ‘Big Bang' nectarine slices. After cutting, nectarine slices were dipped in three different solutions: 1) distilled water, mucilage, glycerol (MC); 2) distilled water, mucilage, glycerol, Tween 20 (TW); 3) distilled water as control (CTR) and were stored for 3, 5, 7 and 12 days at 5°C and 90% RH, in polyethylene terephthalate (PET) packages under passive modified atmosphere condit…
Changes in ascorbic acid content in fresh cut Sicilian yellow-flesh peaches during post harvest and in fresh cuts.
2013
The traditional yellow-flesh peach cultivars Settembrina and Ottobrina di Leonforte, ripen, the former, during the first 10 days of September and, the latter, during the first 10 days of November in Sicily (Italy). During the pit hardening stage, fruit are covered with a paper bag in order to protect them from the Mediterranean fruit fly. To understand their behaviour in term of postharvest manteinance and suitability to minimal processing, Settembrina and Ottobrina di Leonforte were processed (cleaned, washed, peeled, cut, dipped, packed) to obtain fresh-cut peaches. Fresh cut slices were also stored in perforated bi-oriented polystyrene bags, with 2% ascorbic acid and 1% calcium lactate a…
