Ornacitrus: Citrus plants (Citrus spp.) as ornamentals
2019
Abstract The industrial production of citrus plants for ornamental use (ornacitrus) began in Italy at the end of the 1960s due to the need for many citrus nurseries to adapt their activities in a time of crisis for citriculture. Nowadays, the ornamental citrus nursery sector is a well-established industry in many European countries such as Portugal, Spain, Greece, and southern Italy. In Italy, nursery production of ornamental citrus plants has become prominent due to the gradual shutdown of many commercial citrus orchards. Currently, Italy maintains its leadership with more than 5.5 million ornacitrus plants produced annually. Ornamental citrus production regards mainly different cultivars …
Multilocus typing for characterization of ‘Candidatus Phytoplasma asteris’-related strains in several ornamental species in Italy
2018
Different ornamental plants showing symptoms referable to phytoplasma presence and collected between 1993 and 2015 in various floricultural areas in north and south of Italy, enclosing Sicily, resulted to be infected by ‘Candidatus Phytoplasma asteris’-related strains, and after PCR/RFLP identification on 16Sr gene were assigned to 16SrI-B subgroup. These infected samples were employed for phytoplasma strain differentiation on tuf, groel, rp and amp genes. In particular, the 23 phytoplasma strains employed were from hydrangea (5), primula (3), gentian (2), petunia (2) and gerbera (1) samples showing flower virescence; from gladiolus samples both in vivo and in micropropagation (2) showing t…
Scent of Jasmine Attracts Alien Invaders and Records on Citizen Science Platforms: Multiple Introductions of the Invasive Lacebug Corythauma ayyari (…
2020
Simple Summary The distribution of the lacebug Corythauma ayyari, a pest species associated to jasmine plants, has been updated using collections and citizen-science data. The path of introduction of this species in Italy has been inferred with molecular analysis. The results revealed an extent of occurrence in Italy wider than was previously known and the evidence of multiple introduction events. The work shows that citizen science can represent a further tool within the early warning information system for alien species introduction. Abstract The jasmine lacebug Corythauma ayyari is a pest of cultivated and ornamental plants mainly associated to Jasminum spp. This invasive insect is nativ…
Agro-Morphological Characterization of Sicilian Chili Pepper Accessions for Ornamental Purposes
2020
The species belonging to the genus Capsicum have been widely used as decorative vegetables, however only a few genotypes are available for this purpose. The goal of the present work was the agro-morphological characterization of several chili pepper accessions cultivated into different pot sizes (10, 14, 18 or 20 cm diameters). The agro-morphological characterization of 19 accessions was performed following IPGR (International Plant Genetic Resources Institute) descriptors: plant height (PH), plant canopy width (PCW), PH/PCW ratio, plant growth habit, plant visual quality, first flower emission, fruiting start, end of harvest, fruit number, fruit length, fruit width, fruit color at mature s…
Consumers of flowers and ornamental plants: an eploratory survey in the Italian «Mezzogiorno» regions
2010
This paper aims to provide further knowledge of purchase and consumption behaviours with regard to flowers and ornamental plants in the regions of Italian «Mezzogiorno», as an acknowledgement of the centrality of final demand in the chain process. The knowledge of consumption process is fundamental either to the firm – in order to improve commercial strategies – or to competition authorities – with the purpose of implementing more effective policies. From the analysis carried out it emerges that flowers and ornamental plants consumption in the «Mezzogiorno» regions is characterised by a high penetration index and – just with regard to some commodities – by a low purchase frequency. Purchase…
Organizational models in the Sicilian ornamental plant industry: An empirical analysis based on transaction cost theory
2015
The process of market globalization has led to a redefinition of business models in order to compete in domestic and international markets. In the current competitive scenario, the survival of companies is linked to their ability to reduce or contain the sum of both production and transaction costs. The aim of this paper is to identify the existence of similar organizational models of a sample of Sicilian firms active in the Ornamental Plants sector based on those transaction costs that they support in relation to the sales channel and the other human and firm characteristics. Using a clustering procedure, we identified four well-distinct organizational models whose formation is influenced …
The competitive development of flowers and ornamentals firms through the use of web-marketing strategies: a survey in the convergence objective regio…
2011
The growth of ICT, and in particular the integrated use of internet within firm marketing strategies, has brought about deep changes at both sector and firm level. Firm processes have been drastically modified in their communication and promotional aspects. In particular, firmcustomer relationships are changing and therefore internet represents a preferential means, not only for transferring the firm image in the global communication, but above all in order to build a dialogue and a continuous interaction which contribute to consumers’ fidelization. This empirical research proposal is to be considered in the framework of “Business to Consumer” relationships and is addressed to the flowers a…
Valorizzazione produttiva della biodiversità in ambiente mediterraneo: il genere Hypericum
2014
Una conoscenza approfondita delle specie appartenenti al genere Hypericum, finalizzata alla loro introduzione negli ordinamenti colturali come specie di interesse industriale e/o ornamentale, comporta la dettagliata descrizione dei parametri morfologici e ambientali delle piante nei loro siti di vegetazione spontanea, e l’accertamento delle loro caratteristiche fitochimiche. Negli anni 2012-2013 è stata svolta un’attività di ricognizione a tale scopo. In Sicilia le perlustrazioni svolte hanno portato all'individuazione di 23 accessioni di H. perforatum, H. perfoliatum, H. pubescens, H. tetrapterum e H. calycinum; numerose altre se ne sono aggiunte, provenienti dall’appennino tosco-romagnolo…
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…
Population genetics of cucumber mosaic virus infecting medicinal, aromatic and ornamental plants from northern Italy
2012
An epidemiological survey carried at the Herb Garden of Casola Valsenio (Emilia Romagna region; Northern Italy) from 2006 to 2009 resulted in finding Cucumber mosaic virus (CMV) as the infectious agent of several ornamental, medicinal and aromatic plants. All CMV-infected plant species showed leaf symptoms followed, in some cases, by flower colour-breaking and stunting. Genetic analysis consisted in the characterization of movement protein gene of each CMV-isolate by single strand polymorphism analysis and sequencing. Phylogenetic trees identified only two isolates as member of subgroup II, while all other isolates were part of subgroup IA. This survey confirms an unexpected increment of CM…
