Uso di alcuni estratti vegetali come bio-erbicidi
2014
Le infestanti competono con le piante coltivate per la luce, gli elementi nutritivi, l'acqua e lo spazio, e influenzano fortemente le produzioni agrarie sia sotto l'aspetto quantitativo che qualitativo. Normalmente le infestanti riescono ad assorbire e utilizzare l'acqua e gli elementi nutritivi più rapidamente ed efficacemente delle colture principali, accrescendosi più velocemente di queste, fino, talvolta, ad inibirne del tutto lo sviluppo. Nel corso del tempo, alcune infestanti hanno sviluppato meccanismi di resistenza agli erbicidi comunemente utilizzati. Questa acquisizione, unitamente alla necessità di reperire soluzioni al problema della gestione delle infestanti anche in condizioni…
Cultivation of Dill (Anethum graveolens L.) with Different Row Arrangements
2011
Dill (Anethum graveolens L.) is an annual plant from the Umbelliferae. Although in cookery also sprouts and tender leaves are used, the drug from dill is represented by the scented fruits (“seeds”), largely used for flavouring conserved foods and liqueurs, but also by the herbal and cosmetic industry. In this work, we present the results of a trial performed in Sicily, putting under comparison four different row arrangements: CR30 (continuous rows 30 cm apart), CR60 (continuous rows 60 cm apart), CR90 (continuous rows 90 cm apart) and TR (twin rows with a distance of 30 cm inside and 60 cm between twin rows). The plant population on the row (12 plants m-1) was constant and according the row…
Effect of Sowing Time on Coriander Performance in a Semiarid Mediterranean Environment
2006
In semiarid environments, time of sowing is one of the most important factors influencing seed yields. For coriander (Coriandrum sativum L.), the most commonly recommended cropping technique is spring sowing (March–April), since the optimum soil temperature for seed germination ranges between 20 and 23 °C, and the crop shows a remarkable sensitivity to frost and cold. In many semiarid areas of southern Italy, however, the occurrence of prolonged dry periods in summer and spring does not allow for the scheduling of summer crops without irrigation. However, the generally mild winter temperatures and the typical rainfall distribution, which is mostly concentrated over the winter months, could …
Biotechnological Approaches to Increase Essential Oil Yield and Quality in Aromatic Plants: The Lavandula latifolia (Spike Lavender) Example. Past an…
2019
Increasing knowledge about isoprenoid biosynthesis pathways has provided new tools for aromatic plant breeding using biotechnological approaches. Notably, there are possibilities to modify essential oil profiles and enhance production of valuable monoterpenes. This attains a particular significance in Lavandula latifolia Medik. (spike lavender), one of the most important essential oil crops in Spain. This chapter summarizes work done to improve essential oil yield and quality by engineering: (1) the enzymes controlling regulatory steps of methyl-D-erythritol 4-phosphate (MEP) and mevalonic acid (MVA) pathways to increase C5 units employed for monoterpene biosynthesis and (2) the monoterpene…

Nonchemical weeding of medicinal and aromatic plants
2013
International audience; Medicinal and aromatic plants are major crops of domestic and industrial interest. Medicinal and aromatic plants are increasingly organically grown to enhance profitability. However, the presence of weeds may lead to a decrease in both yield and quality. Therefore, nonchemical methods of weed control are needed. In this study, mechanical weeding, flaming, stale seedbed, and biodegradable mulch were tested from 2003/2004 to 2006/2007 on coriander, fennel, and psyllium. Biomass and seed yield were measured. The biomass of weeds remaining at harvest was also measured. Results show a high sensitivity of coriander, fennel, and psyllium crops to the presence of weeds. Stal…
Multifunctional role of medicinal and aromatic plants: Perspectives and constraints
2008
Multifunctionality is one of the newest claims addressed to agricultural practices, that are nowadays requested to overpass their classical role to furnish food and fibers for human needs, also addressing to the fulfillment of other human necessities, such as to accomplish recreational services and to give a contribute for environmental safeguard. Medicinal and aromatic plants (MAPs) may be an important tool for the advancement of agricultural practice towards multifunctionality: they represent a mean for crop (and economical) diversification, contribute to land valorization by means of their aesthetical value, may fit into integrated agro-industrial pathways, may give raw matters and inter…
Cultivation Trials of Dill (Anethum graveolens L.) with Different Row Arrangements

New cropping systems in semi-arid Mediterranean environments: potential role of medicinal and aromatic plants
2005
The semi-arid Mediterranean environments represent somehow “fragile” ecosystems, whose correct management needs some special attention. It is crucial therefore to study and point out some innovative farming systems able to deal with an income for workers, but in the meantime environmentally friendly and requiring the minimum energetic and technical inputs. In such sense, the cultivation of some selected medicinal and aromatic plants (MAPs) could be an important strategy. In our work we made an attempt to to sketch a comprehensive evaluation of the input levels required by 23 selected herbaceous MAPs, taking into consideration the indicative average levels of the energetic (including manpowe…
Plant landscape and phytodiversity in the archeological area of Segesta (NW Sicily)
2018
In the system of Sicilian archaeological parks, the area of Segesta - an ancient city of western Sicily referring to the Carthaginian eparchy, - represents, together with Selinunte, Erice and Mothia, another integrated hotspot of biodiversity and archeaology. The current plant landscape is strongly influenced by a millenary anthropic transformation. There are no residual expressions of the original plant covering that, with reference to the environmental potential of the area, can be traced back to the evergreen Mediterranean forest dominated by Quercus ilex, presently only sporadically occurring in the area of the ruins, together with other species related to associations and upper syntaxa…
