Molecular characterization of cucumber mosaic virus isolates infecting ornamental species cultivated in the botanical garden of Bologna university.
2006
During an epidemiological survey carried out in the Botanical Garden at Bologna University, Cucumber mosaic virus (CMV) has been detected by applying PAS-ELISA technique infecting some ornamental species exhibiting a severe symptomatology on the leaves. Datura innoxia Miller. showed mosaic and leaf-curling; Globularia nudicaulis L. produced narrowed leaves with a yellow mosaic and/or variegation; Eupatorium cannabinum L. showed a systemic chlorotic and/or yellow mosaic and stunting. Reverse transcription-polymerase chain reaction (RT-PCR) and single strand conformation polymorphism (SSCP) were employed to characterise these CMV isolates. Total RNA was extracted from symptomatic leaf samples…
Gli acquisti di prodotti florovivaistici in Italia
2012
This paper examines the consumers’ behaviours in buying flowers and ornamental plants in Italy, through the analysis of attitudes, motivations, preferences and, in particular, of the tendency to purchase organic flowers and ornamental plants. The results if, on the one hand, show a modest spread in purchasing organic flowers and ornamental plants, on the other hand, show a good tendency to purchase and the willingness to pay for organic products, revealing concrete opportunities of growth for this area of the market.
Auxin application and cutting length affect rooting in Cuphea hyssopifolia stem cuttings
2017
The effect of cutting length and indole-3-buyric acid (IBA) application on adventitious root formation stem cuttings was studied in Cuphea hyssopifolia. Softwood terminal cuttings of a clone grown in Sicily were trimmed to three lengths (2, 4 or 6 cm) and inserted to a 1-cm depth in bottom heated plastic trays containing a humidified peat-vermiculite mixture 1:2 (v/v). To verify the cutting response to different auxin concentrations, cuttings were dipped to a 1.0 cm depth in a 500ppm or 1000 ppm IBA solutions for 10 seconds. Cutting percent survival was 100%. Regardless of cutting length, the highest rooting percentage was obtained with IBA at 1000 ppm (avg. 86.7%), whereas rooting signific…
First Report of Phytophthora palmivora on Grevillea spp. in Italy.
2003
The genus Grevillea (family Proteaceae) comprises over 300 species and is a popular and widely cultivated group of Australian plants. In the last 3 years, numerous potted grevilleas with symptoms of decline associated with a rot of feeder roots were found in ornamental nurseries in Sicily. Aboveground symptoms were reduced growth, yellowing of foliage, wilt, dieback, and death of the entire plant. The disease was observed on many commercial cultivars and was especially severe on G. alpina (mountain grevillea), G. juniperina (juniper-leaf grevillea), G. lavandulacea (lavender grevillea), and G. rosmarinifolia (rosemary grevillea) as well as the hybrid cultivars Clearview David (G. lavandula…
Les Campaniformes dans le sud-est de la France
2004
The term "Bell Beaker", in the strict sense, designates a ceramic beaker form with an S-shaped profile that gives it the shape of an inverted bell. This type of drinking-vessel is characterized by both its very particular pattern of decoration and by the generally skilled execution of that decoration. By extension, the decoration characteristic of these beakers bas allowed the expansion of the category "Bell-Beaker" to include other pottery forms and even other types of decoration showing the same tradition, vvhich probably represent an evolution or reproduction of the original Bell Beaker pattern, The recognition of these objects and their definition as a class date to the nineteenth centu…
Position-dependent reproductive success of flowers in Dactylorhiza maculata (Orchidaceae)
2000
1. This study explores the importance of flower position for reproductive success of individual flowers of the deceptive terrestrial orchid, Dactylorhiza maculata (L.) Soo. 2. Upper flowers had smaller lips and produced lighter pollinia than those in other parts of the inflorescence, probably due to architectural effects. 3. Dry weight of seed capsules decreased from bottom to top in the inflorescence in both open-pollinated and hand-pollinated plants. However, removal of flowers from the middle and lowest parts of the inflorescence considerably increased seed production of the upper flowers. Decreased seed set was due to decreased resource availability because of the long maintenance time …

First Report of Leaf Spot and Blight Caused by Ralstonia pickettii on Bird of Paradise Tree in Italy
2008
Bird of Paradise tree (Strelitzia alba (L. f.) Skeels) is an ornamental perennial tropical plant grown in southern Italy. In the summer of 2006 and 2007, a widespread, severe leaf disease was observed on seedlings and 1- to 2-year-old plants in two glasshouses located in eastern Sicily. Disease incidence ranged from 10 to 25%. Symptoms on the leaves consisted of dark brown-to-black stripes of varying length and found between the lateral veins. Lesions sometimes coalesced into a large area of necrotic tissue. Symptomatic tissues were ground in a drop of sterile distilled water (SDW) with a scalpel. Suspensions were streaked on King's medium B (KB), nutrient agar, and yeast extract nutrient …
Estetiche dell’ornamento
2006
Nell’architettura, tra la fine del secondo e l’inizio del terzo millennio, si assiste al crollo di quei principi di firmitas, utilitas e venustas che, da Vitruvio in poi, erano stati alla base dell’arte dell’edificare; ai valori del peso, della struttura, dell’ornamento subentrano altre categorie estetiche: l’immaterialità, la multimedialità, la sensorialità. Pertanto non si può più parlare di ornamento secondo le chiavi di lettura tradizionali, quali ad esempio la dialettica struttura/decorazione o utile/superfluo, ma è preferibile ricorrere ad un linguaggio metaforico che, gravitando nell’ambito semantico del “corpo”, della “veste”, del “trucco” e della “maschera”, coinvolge spesso la pol…
La imagen del mundo clásico en la figura del mecenas Antonio Pontons
1995
El trabajo explica la relación entre la persona que encarga o compra una obra de arte -conocida habitualmente como "mecenas"- y el artista. En este caso se trata de la persona del valenciano Antonio Pontons y el escultor genovés Ponzanelli. Éste es autor de las seis esculturas que adornaban el llamado "Huerto de Pontons", mansión y jardines situados en las cercanías de la ciudad de Valencia. Dicho huerto fue destruido a principios del presente siglo aunque se conservan las esculturas.
