A new species of Ferula (Apiaceae) from Malta

2018

Ferula melitensis, a new species from the Malta Archipelago, is described and illustrated. It belongs to the taxonomic group of F. communis, showing close relationships mainly with F. tunetana, F. arrigonii, F. communis s.str. and F. glauca, from which it differs in several features regarding the stem, leaves (mainly for shape and size of terminal segments), flowers and mericarps; other significant differences regard the ecology and phenology. The investigations, carried out on living plants, herbarium material and literature data, regard the morphological analysis of vegetative and reproductive structures, the anatomy of terminal leaf segments and mericarps, as well as the shape and size o…

Variations in the volatile compounds of a Fennel (Foeniculum vulgare Mill.) variety grown in a semi-arid Mediterranean environment

2005

Fennel is an industrial source of anethole but, recently, further interest has came from the suggested possibility of many industrial uses of this plant. The volatile substances from the seeds of fennel grown in Sparacia (Cammarata - AG - Sicily; 37° 38' N; 13° 46' E) have been investigated and compared on a statistical base with previously reported data. The variety grown in Sparacia fall into the "high fenchone" chemovariety. The substances alpha-toluene, alpha-terpinene, beta-phellandrene + limonene and camphene appear the components most sensitive to environment and grow condition modifications. Fennel is an industrial source of anethole but, recently, further interest has come from the…

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…

Assessment of the insecticidal activity of five essential oils used against the subterranean termite Reticulitermes lucifugus (Rossi) (Blattodea, Rhi…

2023

Among Reticulitermes genus the most abundant species living in Italy is Reticulitermes lucifugus Rossi. This termite is very dangerous to wooden structures of artistic heritage and buildings. The traditional control of R. lucifugus is very difficult resulting in negatively impact on the environment, therefore the use of phytochemical, such as essential oils (EOs), could lead to an alternative to synthetic insecticides, with advantages in reducing environmental risks. In this work we investigated the insecticidal activity of EOs of Citrus bergamia Risso, Syzygium aromaticum L., Foeniculum vulgare Mill., Pelargonium odoratissimum L., and Origanum vulgare L. by inhalation against R. lucifugus …

Non-chemical weeds management in two Mediterranean culinary herbs

2009

Weeds management is one of the most relevant constraints to the cultivation of Medicinal and Aromatic Plants, especially when they’re cultivated with “organic” methods, that, according to EU regulations, do not allow the use of chemicals. A strong interest is therefore devoted to pointing out “alternative” (agronomical and physical) methods for weeds control. This work reports the results of a trial performed in 2003-04 and 2004-05 in order to evaluate the effects on Coriander (Coriandrum sativum L.) and Fennel (Foeniculum vulgare Mill.) of four non-chemical methods for weeds control: FS (False seeding), PD (Flaming), MZ (Mechanical weeding), SM (Hand weeding) compared with two untreated co…
