Micropropagation ofAgeratum houstonianumby nodal segments
2017
Ageratum houstonianum is a bedding and flowering potted plant originated from Central America which is generally propagate by seed. In this report a preliminary in vitro technique for propagation of A. houstonianum was investigated. In vitro germinated seeds were used to establish aseptic shoot cultures of several clones. Seedling stem segments bearing 3-4 nodes were placed on Murashige and Skoog (MS) basal medium plus 20 g L-1 sucrose, 8.0 g L-1 Agar to induce axillary shoot development. Axillary shoots were subcultured into the same medium and nodal segments were sectioned and subcultured to increase the stock of shoot cultures. Shoot cultures of the selected clone AG14 were used to accom…
COLLARD GREEN (BRASSICA OLERACEA VAR. ACEPHALA) CULTIVATION IN SICILY
2013
Collard greens (Brassica oleracea var. acephala) are a group of plants cultivated for its thick, slightly bitter, edible leaves. As other Brassicaceae, have a good nutritional value as they are a good sources of vitamin C and soluble fiber, and contain various compounds with potent anticancer properties. In order to enhance collard cultivation in Sicily, different planting dates were tested. The research was carried out during 2009-2010 in the experimental field of SAgA Department – University of Palermo. Plants of a Sicilian local cultivar, with high vigor, good emission of side shoots, large and moderately curly leaves and long and strong petiole, were planted in three different periods: …
Microbiological investigation of Raphanus sativus L. grown hydroponically in nutrient solutions contaminated with spoilage and pathogenic bacteria
2012
Abstract The survival of eight undesired (spoilage/pathogenic) food related bacteria (Citrobacter freundii PSS60, Enterobacter spp. PSS11, Escherichia coli PSS2, Klebsiella oxytoca PSS82, Serratia grimesii PSS72, Pseudomonas putida PSS21, Stenotrophomonas maltophilia PSS52 and Listeria monocytogenes ATCC 19114T) was investigated in mineral nutrient solution (MNS) during the crop cycle of radishes (Raphanus sativus L.) cultivated in hydroponics in a greenhouse. MNSs were microbiologically analyzed weekly by plate count. The evolution of the pure cultures was also evaluated in sterile MNS in test tubes. The inoculated trials contained an initial total mesophilic count (TMC) ranging between 6.…
ARBUSCULAR MYCORRHIZAL INOCULATION AND SHADING ENHANCE CROP PERFORMANCE AND QUALITY OF GREENHOUSE Begonia semperflorens
2019
Mycorrhizal fungi are gaining interest in the floriculture sector due to the beneficial effects on a crop performance and ornamental quality. The aim of the current study was to assess the effect of inoculation with the arbuscular mycorrhizal (AM) fungi Rhizophagus irregularis on ornamental quality of Begonia × semperflorens-cultorum grown in two different protected cultivation systems: a shadehouse or glasshouse. The inoculated plants incurred a significant increase of plant height by 34.6%, lateral shoot length by 27.9%, number of lateral shoots by 41.2%, number of flowers per plant by 102.9%, flower diameter by 27.5%, and stems dry weight by 263.6%. High temperatures in the glasshouse ne…

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…
