Valorization of Mediterranean Species of Thyme for the Formulation of Bio-Herbicides
Get PDFThis study focused on the evaluation of the phytotoxic activity of four essential oils (EOs)
from the Mediterranean species of Thymus sp. pl., namely Thymus algeriensis Boiss. et Reut., T. ciliatus
Desf. subspecies coloratus (Boiss. et Reut.) Batt., T. vulgaris L. ecotype Fasano and T. vulgaris cultivar
L. Varico 3, to identify new biomolecules with herbicide potential. The chemical characterization of
EOs was performed by GC-MS. The evaluation of the phytotoxicity of the EOs was conducted under
in vitro conditions, and the inhibition of germination and seedling growth of Lolium perenne L. and
Amaranthus retroflexus L. were assessed. Five concentrations (100, 250, 500, 750 and 1000 μL/100 mL)
were considered. Phytochemical analysis revealed a great diversity of compounds. T. algeriensis and
T. ciliatus EOs were characterized by the absence of carvacrol and a low content of thymol in T. ciliatus.
On the contrary, T. vulgaris ecotype Fasano and T. vulgaris cultivar Varico 3 were characterized by an
important content of p-cymene, thymol and carvacrol. All the EOs expressed a potent phytotoxic
activity against the tested species. The total inhibition of seed germination and seedling growth were
recorded for the highest concentrations of all the EOs. T. vulgaris ecotype Fasano expressed the most
effective activity
Stakeholders’ perception of Xylella fastidiosa (Xf) disease risk assessment: First results from Puglia (IT), Chania (GR), Valencia and Andalucia (ES)
Get PDFXylella fastidiosa (Xf) is an aerobic, Gram-negative bacterium of the monotypic genus Xylella. It is transmitted exclusively by xylem fluid feeding sap insects. Xf is one of the most dangerous plant bacteria worldwide, causing a variety of diseases, with huge impact for agriculture, and affecting cultivated plants of high economic value (e.g., olive trees, stone fruits—plums, almonds, cherries) or wide-spread ornamental plants (e.g., myrtle-leaf milkwort, oleander). In the frame of H2020 Project XF-ACTORS, analysis of the environmental, socio-economic and governance impact and vulnerability to Xf have been carried out in selected case study areas. To reach this goal, an extensive survey was conducted with the support of a comprehensive questionnaire in Puglia (Italy), Crete (Greece), Valencia and Andalusia (Spain). Questionnaires were completed through face-to-face interviews with local farmers, decision makers, extension experts and practitioners. The survey aimed to: 1) collect the point of view and perception of people about Xf disease and the containment plans; 2) identify possible gaps in communication, understand possible weak points in the communication strategy that could hamper the application and the effectiveness of containment measures; 3) understand the network of relationships existing among stakeholders in territorial contexts; and 4) collect suggestions from local people with a view to improving the management of information related to the disease. Questions were grouped under different main criteria: Knowledge, Perception, Practices, Involvement, Effectiveness, Responsibility. A scoring procedure assigned to each question a value to assess the corresponding indexes: DKI-Disease Knowledge Index, DPI-Disease Perception Index, FPI-Farm Practices Index, INV-Involvement Index, EFF-Effectiveness Index, RES-Responsibility Index. The overall values of RISK (DKI/DPI/FPI) and GOVERNANCE (INV/EFF/RES) were then obtained. To investigate linkages (correlation and causation) between Governance and Risk (perception and management) domains as well as among their indices, Structural Equation Modelling (SEM) technique was adopted. The proposed methodology proves to be useful to describe attitudes of respondents when facing the epidemic, as well as how they appreciate and tackle disease management. The work allows practical suggestions to be made to improve the knowledge-perception relationship that directly influences willingness to adopt preventive/control measures against the pathogen, and consequently will increase the efficiency of Xf disease management. The result of the whole analyses confirmed that the engagement of stakeholders, the involvement of expert groups (enlarged to experts in economy and social science) and an appropriate communication strategy are essential for a successful implementation of phytosanitary measures

Vascular flora of the ancient olive groves of Apulia (southern Italy)
Get PDFU razdoblju od 2009. do 2012. istraživana je vaskularna flora starih maslinika Apulije (Italija). Istraživanje se usredotočilo na polja i ekološku infrastrukturu četiri maslinika. Sveukupno je zabilježeno 408 svojti, od toga 332 vrste, 73 podvrste i 3 kultivirana varijeteta, smještenih u 275 rodova i 74 porodice. Samo 18 svojti od njih 408 se smatra važnima u smislu zaštite. Tih 18 svojti su podrobnije analizirane, i u skladu s Direktivom 92/43/EEC za njih je zabilježena topografija nalazišta, biljna zajednica, gustoća populacije i suodnos sa staništem. Istraživanje je planirano i izvedeno u cilju pronalaženja načina za poboljšanje zaštite i upravljanja maslinicima u Apuliji.A floristic study of the vascular flora of ancient olive groves of Apulia (Italy) was carried out from 2009 to 2012. Research was mainly focussed on the fields and the ecological infrastructures of four olive groves. In total, 408 taxa were identified, of those, 332 species, 73 subspecies and 3 cultivated varieties were classified into 275 genera and 74 families. Only 18 taxa out of the 408 were considered important from a conservation point of view. These 18 taxa were analysed more thoroughly, the topography of the collecting site, plant community, population density and relationships with the habitats being recorded, according to Directive 92/43/EEC. The work was planned and carried out with the aim of providing tools for improving the conservation and management of the olive groves of Apulia
