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…
Florintesa, a program agreement for the italian botanical gardens and the national floristic heritage.
2014
OUR CLAIM: "The Botanical Gardens are, par excellence, responsible for carrying out the important mission of the conservation of our flora, through specific actions on live plants and their seeds, along with education and outreach aimed at spreading a new environmental culture, more careful and respectful of the essential needs of life, more sensible to the aesthetic and scientific value of the national flora" To overcome the isolation and strengthen their role in our society, the University Botanical Gardens have become promoters of national and European consortiums: examples are the working group "Botanical and Historic Gardens" of the Italian Botanical Society (1) and, on the global leve…
Methods of the investigation of bee pollen and bee bread
2017
The main purpose of this publication was to evaluate which types of studies are used with the purpose of the estimation of nutritional value of bee pollen and bee bread. Bee pollen and bee bread are important bee-products that contains large amounts of nutritional and essential active biological compounds. Among different bioactive compounds with antioxidant properties which could be found in bee pollen and bread are polyphenolic substances, flavonoids, unsaturated acids and carotenoids. Bee pollen and bee bread are investigated by plenty of scientists for different quality indexes over two last decades. However, the composition of bee pollen and bee bread are not yet standardized nor defin…
Comparative Study of Several Machine Learning Algorithms for Classification of Unifloral Honeys
2021
Unifloral honeys are highly demanded by honey consumers, especially in Europe. To ensure that a honey belongs to a very appreciated botanical class, the classical methodology is palynological analysis to identify and count pollen grains. Highly trained personnel are needed to perform this task, which complicates the characterization of honey botanical origins. Organoleptic assessment of honey by expert personnel helps to confirm such classification. In this study, the ability of different machine learning (ML) algorithms to correctly classify seven types of Spanish honeys of single botanical origins (rosemary, citrus, lavender, sunflower, eucalyptus, heather and forest honeydew) was investi…
Riflessioni "a margine". Il workshop "Sul margine dell'Orto Botanico di Palermo" dal punto di vista di una storica dell'arte
2020
The paper is the result of a historical research conducted during the Architecture workshop "Sul margine dell'Orto Botanico di Palermo. Spazi per Visiting Professor" ("On the edge of the Botanical Garden of Palermo. Spaces for Visiting Professor"), organized from 24 to 27 September 2018 by the Professors of the University of Palermo Andrea Sciascia, Giuseppe Di Benedetto, Giuseppe Marsala and Antonino Margagliotta and included in the teaching activities of the PhD in Architecture, Arts and Planning. It consists of a descriptive part of the Manifesta12 interventions – the prestigious nomadic Biennial of contemporary art whose last edition took place in Palermo – at the Botanical Garden. This…
Dianthus superbus as a critically endangered species in Latvia: evaluation of its growth conditions and conservation possibilities
2021
Abstract Dianthus superbus is one of the most endangered species in Latvia and is on the verge of local extinction. Therefore, the aim of this study was to inventory previously identified populations of D. superbus in Latvia and to develop activities to conserve this species in accordance with the results obtained in situ. Expeditions on 18 previously documented locations, according to the data of Nature Conservation Agency, revealed only three existing D. superbus localities in Latvia with a significant number of specimens located in the Latgale region near Silenieki. In 2020, for the first time, two more new D. superbus localities were found in the vicinity of these three approved locatio…
A prioritised inventory of crop wild relatives and wild harvested plants of Tunisia
2022
AbstractAn inventory of crop wild relatives (CWR) and wild harvested plants (WHP) occurring in Tunisia, based on the integration of the last available floristic checklists, is presented. The taxa were prioritised according to economic value of the related crop, potential for crop improvement, threat status, endemism, inclusion in the ITPGRFA (Annex I) and average annual contributions to dietary energy (kilocalories) per capita per day by applying a scoring system based on 4 priority levels. Of a total of 2912 taxa belonging to the Tunisian Flora, 2504 CWR and/or WHP (86% of the total), from 143 families and 686 genera, were identified, 2445 of which are CWR and 847 are WHP. In detail, 1654 …
The Prairie Diagnosis: a tool to assess and characterize the grassland base of long-term temporary and permanent grasslands
2022
Permanent and temporary grasslands represent nearly 44 % of the French UAA. This vast area is rich in a very wide range of flora, from hillside meadows with subterranean clover to flooded meadows and marshes with Baldingere, not forgetting sown meadows which, over the years, can host numerous spontaneous species. The method of prairie diagnosis is based on a botanical approach to the prairie with the objective of qualifying the forage aptitudes of the cover. The diagnosis of a meadow is only of interest and relevance if it is integrated into a forage system consistent with the strategies of a farmer. It is based on the premise that the flora of a meadow is the result of the interaction of "…
Ethnobotanical investigation on wild medicinal plants in the Monti Sicani Regional Park (Sicily, Italy)
2014
Ethnopharmacological relevance The area of the "Monte Sicani Regional Park" (Central Western Sicily, southern Italy) has been quantitatively and extensively investigated in an ethnobotanical study for the first time. A total of 108 wild species are used for medicinal purposes, while, according to our study, the uses of 9 species have not previously been reported in ethnobotanical studies in Italy (e.g.; the use of Kickxia elatine (L.) Dumort. for the treatment of hyperhydrosis of the feet, the use of Lavatera agrigentina Tineo for cough and bronchitis). Aim of the study: The aim of this paper is to analyze, through quantitative indicators, the extent of the current knowledge on medicinal us…
"Z ekologią za pan brat". Turystyka kulturowo-przyrodnicza na przykładzie parafialnego ogrodu botanicznego w Bujakowie (województwo śląskie)
2017
Przedmiotem niniejszego opracowania jest parafialny ogród botaniczny znajdujący się w jednej z miejscowości w województwie śląskim - Bujakowie (dzielnicy Mikołowa). Ogród o powierzchni 1 ha powstał w latach 70. XX wieku. Pomysłodawcą jego założenia był proboszcz miejscowego kościoła pw. św. Mikołaja. Bezpośrednio z funkcjonowaniem ogrodu związane jest ustanowienie w 2000 roku w Bujakowie sanktuarium Matki Bożej Bujakowskiej - patronki środowiska naturalnego. Dla mieszkańców miejscowości i okolic ogród pełni ważne funkcje (rekreacyjną, edukacyjną, ludyczną, kulturotwórczą), jest również rozpoznawalnym miejscem w turystyce przyrodniczej na obszarze województwa śląskiego.
