Mapping quantitative trait loci affecting biochemical and morphological fruit properties in eggplant (Solanum melongena L.)
2016
Eggplant berries are a source of health-promoting metabolites including antioxidant and nutraceutical compounds, mainly anthocyanins and chlorogenic acid; however, they also contain some anti-nutritional compounds such as steroidal glycoalkaloids (SGA) and saponins, which are responsible for the bitter taste of the flesh and with potential toxic effects on humans. Up to now, Quantitative Trait Loci (QTL) for the metabolic content are far from being characterized in eggplant, thus hampering the application of breeding programs aimed at improving its fruit quality. Here we report on the identification of some QTL for the fruit metabolic content in an F2 intraspecific mapping population of 156…
Micropropagation of Globe Artichoke (Cynara cardunculus L. var. scolymus).
2013
The globe artichoke (Cynara cardunculus L. var. scolymus) is a perennial plant cultivated in the Mediterranean region and the Americas for its edible young flower heads. Although vegetative propagation by offshoots or by “ovoli” (underground dormant axillary buds) has been the primary method of propagation, the potential for the diffusion of diseases and the phenotypic variability can be very high. The propagation of this species by axillary shoot proliferation from in vitro cultured meristems produces systemic pathogen free plants and a higher multiplication rate as compared to that obtained by conventional agamic multiplication. Axillary shoot proliferation can be induced from excised sho…
LE SPECIE DELLA FLORA VASCOLARE SICILIANA INCLUSE NELLE NORMATIVE INTERNAZIONALI
2012
Species of sicilian vascular flora included in the international laws. The present paper aims to divulgate the knowledge of the Sicilian flora protected at international level and includes a check-list of the Sicilian vascular flora recorded in international normatives on the protection of nature and biodiversity. For each normative general information is given together with a reference list to further deepen the contents, the aims and the present implementation in Italy.
Effect of Nitrogen Fertilization on the Quality of Swiss Chard at Harvest and during Storage as Minimally Processed Produce
2014
The effects of different levels of nitrogen fertilization (0-50-100-150-200 kg ha-1), minimal processing and cold storage (14 days at 4°C) on yield and quality of fresh-cut Swiss Chard (Beta vulgaris L. var. cicla L.) were evaluated. Increasing the level of nitrogen fertilization over 100 kg N ha-1, plants had a higher fresh weight, reduced their dry matter content and resulted taller and leafier. Total and marketable yield increased linearly as increasing nitrogen level. Both nitrate and ascorbic acid content at harvest increased as increasing nitrogen supply. Nitrogen fertilization negatively affected the yield of minimal processing. No effect on appearance and quality loss during cold st…
Citazione del progetto dell'autore in F. Purini, Vema, una nuova città italiana per la Biennale di Venezia.
2006
Il progetto è citato nel saggio introduttivo di F. Purini, che concerne l’esplorazione progettuale presentata alla X Biennale di Venezia: Vema, una nuova città italiana. I venti progettisti, tra cui Santo Giunta, sono stati selezionati tramite una ricognizione su libri e riviste, tenendo anche conto della complessità della scena architettonica italiana, che presenta notevoli articolazioni regionali oltre a consistenti e profonde differenze di impostazione tra le numerose scuole di architettura.

Prove preliminari per la valorizzazione della borragine (Borrago officinalis L.) come prodotto minimamente processato
2012
La borragine (Borago officinalis L.) è una pianta erbacea annuale tomentosa della famiglia Boraginaceae originaria dell'Europa e del Nord Africa, ampiamente diffusa in molti paesi mediterranei. Questa pianta è coltivata in tutto il mondo ed è usata per scopi medicinali nonché per la preparazione di bevande e per essere consumata cruda o cotta. La coltivazione della borragine è principalmente orientata alla produzione di seme, mentre la coltura da ortaggio è molto limitata e spesso si ricorre alla raccolta delle piante spontanee per soddisfare le richieste di mercato. Al fine di valorizzare il potenziale orticolo di questa specie, la presente ricerca ha lo scopo di valutare la possibilità di…
Effects of packaging on shelf-life and quality of minimally processed fennel
2018
Fennel is not a widespread product among minimally processed vegetables, due to the fast deterioration mainly caused by browning of the cut surfaces, even during cold storage. In order to extend the shelf-life of fresh-cut fennel, the influence of different packaging techniques was studied. Sliced fennel, dipped in a citric acid solution (0.5%), was placed in polystyrene trays, sealed with PE film or vacuum packaged in PE bags and stored up to 14 days at 4°C. During this period the weight loss, soluble solid content, pH, color and firmness were evaluated. Minimally processed fennel packed in sealed trays and cold-stored at 4°C, extended its shelf-life to 14 days maintaining acceptable quali…
Assessing Hydrus-2D model to investigate the effects of different on-farm irrigation strategies on potato crop under subsurface drip irrigation
2019
The objective of this paper was to assess the performance of Hydrus-2D model to simulate the effects of different on-farm irrigation strategies applied on potato crop. The ability of the model to simulate the stress coefficient (Ks), obtained as the ratio between actual and maximum transpiration, and to define the productive function of potato crop under the semi-arid conditions of central Tunisia were also evaluated. Experiments were carried out on potato crop under full (FI) and deficit irrigation (DI) and two different water qualities supplied by means of a subsurface drip irrigation system. Results evidenced that the model, despite some discrepancies locally observed, can fairly accurat…
