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…
Invasive Aliens in Italy: Enumeration, History, Biology and Their Impact
2021
Italy includes two large islands, Sardinia and Sicily, and a peninsula separated from the European continent by the Alpine Arch. At national level ISPRA (Instituto Superiore per la Protezione e la Ricerca Ambientale, Higher Institute for Environmental protection and research) is the instrument of the Ministry of Environment and for the Protection of the Territory and the Sea to carry out its mission, including the study, monitoring, and control of invasive alien species. Universities, Scientific Societies, and ONGs play a vital role in basic research. The interest in the study of alien plants is of a theoretical nature, as regards the migrations of living beings and interactions with native…
Constructed Wetlands as Sustainable Technology for the Treatment and Reuse of the First-Flush Stormwater in Agriculture—A Case Study in Sicily (Italy)
2020
This paper describes a case study that was carried out on a Sicilian company (Italy) dealing with separate waste collection and recycling of glass. The aims of this study were to evaluate the overall efficiency of a vertical subsurface flow system (VSSFs) constructed wetland (CW) operating for the treatment of first-flush stormwater and the effects of treated wastewater on the morphological and aesthetic characteristics of ornamental pepper and rosemary plants. The system had a total surface area of 46.80 m2 and was planted with common reed and giant reed. Wastewater samples were taken from October 2018 to July 2019 at the CW inlet and outlet for chemical-physical and microbiological charac…

The Aesthetic of Louis H. Sullivan: Between Ornament and Functionality
2012
La questione dell'ornamento è stata spesso interpretata alla luce della dialettica utile /superfluo, vertendo verso l'una o l'altra ipotesi a seconda dei differenti contesti teorici. Tuttavia nello scorcio del XIX secolo, nell'era della macchina, l'estetica organicistica di Louis H. Sullivan aveva conferito alla teoria, di matrice vitruviana e albertiana, nuovo vigore, sostanziandola col trascendentalismo di Emerson e Whitman e con l'evoluzionismo di Darwin e Spencer. Sulla base di un'analogia biologica per Sullivan l'ornamento è parte integrante alla struttura dell'edificio come il fiore alla pianta e di conseguenza la forma risponde ad esigenze funzionali. Gli scritti di Sullivan ebbero u…
Color Signals in the Black Grouse (Tetrao tetrix): Signal Properties and Their Condition Dependency
2009
Recent progress in techniques of quantifying between-individual differences of color-based ornaments has revealed undiscovered possibilities for research in sexual selection. We present how the color spectra data can be comprehensively used for studying the importance of sexual ornaments in the black grouse and how these ornaments are related to a male condition. For this, we used both correlative field and experimental data. Field data indicated that older males had more chromatic coloration than yearlings. Blue chroma of males was correlated with male mating success. We experimentally manipulated yearling birds with testosterone implants and found that testosterone-implanted males had imp…
The evolution of mating preferences for genetic attractiveness and quality in the presence of sensory bias.
2022
The aesthetic preferences of potential mates have driven the evolution of a baffling diversity of elaborate ornaments. Which fitness benefit—if any—choosers gain from expressing such preferences is controversial, however. Here, we simulate the evolution of preferences for multiple ornament types (e.g., “Fisherian,” “handicap,” and “indicator” ornaments) that differ in their associations with genes for attractiveness and other components of fitness. We model the costs of preference expression in a biologically plausible way, which decouples costly mate search from cost-free preferences. Ornaments of all types evolved in our model, but their occurrence was far from random. Females typically p…
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, …
Beyond Characterisation. Polished Stone Exchange in the Western Mediterranean 5500-2000 BC
2001
Using new provenance studies on stone implements from the Valencia region of Spain between 5500-2000 BC, we show not only the large scale of some exchange systems, but also consider how, and why, tastes and fashions are co-ordinated over much of the Western Mediterranean. The study considers the processes of raw material substitution underlying the observed patterns. These processes operate for a wide range of lithic materials, including rare minerals like variscite and fossil shells for ornaments. Simple gravity models of distribution and exchange predominate at all periods. Our study extends from Portugal to Italy, and indicates that a system of shared symbolic values, of axeheads, beads …
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…
