Effetto della forma azotata e della modalità di distribuzione sulla produzione e la qualità di lattuga

Effetto sugli aspetti morfologici e riproduttivi dell’esposizione di semi di Lagenaria siceraria a campi magnetici
2012
La lagenaria è una cucurbitacea conosciuta da più di 15000 anni per la commestibilità dei frutti immaturi e dei germogli, ma anche per le proprietà medicinali e per i diversi utilizzi cui può essere destinato il frutto maturo. E’ noto che i campi magnetici, con intensità di 1-2 ordini di grandezza al di sopra della forza del campo geomagnetico, possono influenzare la crescita e il metabolismo in una moltitudine di modi. In questo ambito, la ricerca condotta mira a valutare l’effetto che i trattamenti magnetici a semi di Lagenaria possono avere sulle piante da essi ottenute, con particolare riferimento alla biologia fiorale e alla produttività delle piante stesse. Semi di Lagenaria siceraria…
Idoneità alla minima lavorazione dei frutti di Lagenaria siceraria L.
2012
La lagenaria (Lagenaria siceraria (Molina) Standl.) è una cucurbitacea conosciuta da più di 15000 anni per la commestibilità dei frutti immaturi e dei germogli ma anche per le proprietà medicinali e per i diversi utilizzi cui può essere destinato il frutto maturo. Seppure la coltivazione della Lagenaria è ampiamente diffusa in Asia, in Europa, e nei paesi occidentali in genere, il suo utilizzo è limitato ad alcune zone circoscritte nelle quali riscuote l’apprezzamento dei consumatori. Pertanto questa specie presenta un notevole potenziale commerciale per l’eventuale diffusione in nuovi mercati. A tal fine si è voluta valutare la possibilità di trasformare i frutti di lagenaria in prodotto d…

Effect of nitrogen fertilizer level on quality and shelf-life of fresh cut Swiss chard
2018
Swiss chard (Beta vulgaris L. var. cicla L.) is a leafy vegetable highly appreciated in some areas for its nutritional properties and year round supply. Its production area is not commercially important, but this minor vegetable offers an interesting enlargement of the current vegetable assortment by using its stalks and leaves. Swiss chard is a very nutritive demanding species. The content of mineral elements, total quality and yield are influenced by the amount, frequency and method of fertilization. The aim of this study was to evaluate the effect of high or low levels of nitrogen fertilization on the quality and shelf-life of minimally processed Swiss chard. Plants grown with a high (18…

Polyethylene and Biodegradable Starch-Based Mulching Films Positively Affect Winter Melon Production in Sicily
2014
Plastic mulching is widely used in many regions of the world for growing melons. The winter melon is largely grown in the hilly countryside of the Mediterranean island of Sicily (Italy) where mulching plastic films enhance early and total yields. However, removing and disposal of polyethylene plastic mulches after use represent a major disadvantage and an environmental concern. The objective of this trial was to compare the effects of polyethylene (PE) (transparent and black) and biodegradable (black) mulching films on yield, fruit size and quality of melon grown in the open field. The trial was conducted in the north-western coast of Sicily in the province of Trapani, 250-m elevation. Melo…
Propagation techniques for three Mediterranean native shrubs with potentential as ornamental outdoor plants
2006
Grande are three Mediterranean shrubs with interesting ornamental features. The exploitation of wild plants for ornamental purposes implies knowledge on the factors influencing the propagation methods. To study the influence of temperature on germination, seeds of Teucrium flavum, Prasium majus and Micromeria fruticulosa were germinated in incubators at constant temperatures of 14, 20, 24 and 28°C. Highest germination, 45 % and 86%, occurred at 20°C in Teucrium flavum and Prasium majus, respectively. Micromeria fruticulosa seeds subjected at 24 or 28°C had a germination percentage significantly higher than at 20 or 14°C. To study the influence of auxin treatments on vegetative propagation, …
Adaptation of the tropical hybrid Euphorbia×lomi Rauh to the exposure to the Mediterranean temperature extremes
2014
Abstract Poysean ( Euphorbia × lomi Rauh) has been introduced in the Mediterranean countries as an ornamental plant for indoor uses. When used outdoor, few information is available about its ability to withstand the Mediterranean temperature extremes. An experiment in an open stand was performed to evaluate poysean tolerance to the winter and summer temperatures of the thermo Mediterranean climate and its ornamental value for urban greening. Two genotypes of poysean (Nguen Muang, NM; and Soi Budsanin, SB) with similar bracts and flower colours were grown at either 2 or 3 plants per pot during 23 months. Number of flower racemes and leaves per plant and plant height were recorded monthly. Ov…
EFFECT OF CULTIVAR AND CROWN SIZE ON YIELD AND QUALITY OF STRAWBERRY FRESH BARE ROOT PLANTS IN SICILY
2012
In the southern regions of Mediterranean areas the plantations with fresh plants (winter planting system) have almost completely replaced those with cold stored plants (summer planting system). Particularly, fresh bare root plants produced in high elevation nurseries located in Spain and Poland and, in experimental phase, in the southern of Italy (in the mountains of Sicily, Calabria, Basilicata) are the most used. Such type of plant usually has a crown diameter from 6 to 14 mm, but the smallest plants should be (<8 mm) discarded in phase of selection and packing. Objective of this study was to investigate the influence of the different crown diameter on the earliness, productivity and qual…
