Characterization of Sicilian rosemary (Rosmarinus officinalis L.) germplasm through a multidisciplinary approach.

2020

In Sicily, small differences exist between wild and cultivated rosemary biotypes; VOCs and genetic profiles may be a useful tool to distinguish them. A germplasm collection of Rosmarinus officinalis L. was harvested from 15 locations in Sicily. Eleven wild and four cultivated populations were collected and, due to the surveyed area covered, they can be considered as a representative panel of Sicilian genetic background of the species. Ex situ plant collection was transferred to the field cultivation in homogeneous conditions for characterizing through a multidisciplinary approach. The study included morphological traits observations (growth habitus, flower color, number and size of leaves, …

Agronomic Evaluation and Chemical Characterization of Sicilian Salvia sclarea L. Accessions

2020

Clary sage (Salvia sclarea L.), known for its aromatic and medicinal properties, belongs to the Lamiaceae family. Although the species grows wild throughout Sicily, knowledge of its production and qualitative properties is limited. The aim of this study was to evaluate the agronomic behavior of the species over two years of testing and to characterize the chemical properties of its wild counterparts in order to identify the most promising accessions for cropping or for use in breeding programs. Tests were carried out during 2008, 2009, and 2010. During the first year, the plot was established. Subsequently, the main parameters for bio-agronomic evaluation were taken in 2009 and 2010. Regard…

Sustainable production of fennel and dill by intercropping

2008

Intercropping is claimed to be one of the most significant cropping techniques in sustainable agriculture, and much research and many reviews attribute to its utilization a number of environmental benefits, from promoting land biodiversity to diversifying agricultural outcome. In this sense, intercropping is thought to be a useful means of minimizing the risks of agricultural production in many environments, including those typical of under-developed or marginal areas. In order to validate this hypothesis in a representative area of the semiarid Mediterranean environment, we evaluated the possibility of growing dill and fennel, both belonging to the family Apiaceae, in temporary intercroppi…

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…

Prove di coltivazione di Calendula (Calendula officinalis L.) in ambiente semi-arido

2008

Inside the family Asteraceae, Marigold is one of the most relevant species bearing some herbal interest. The evaluation of the bio-agronomical and yield response of the species to the field cropping conditions, especially when a low input cropping technique is applied, is the base for its full exploitation. With this objective, a long-term research activity has been started out by the DAAT (Department of Environmental and Land Agronomy) of the University of Palermo in the experimental farm “Sparacia” (Cammarata – AG – Sicily), performing observations on Marigold plants managed with a minimum recourse to external technical inputs (nor pesticides neither chemical weeding, and a light (50 kg h…

Nitrogen fertilisation in coriander (Coriandrum sativumL.): a review and meta-analysis

2009

Nitrogen (N) fertilisation is one of the most important external inputs in assessing coriander seed yield and plant growth. Recent concerns related to the misuse of N fertilisers in agricultural environments, however, stress the opportunity for a fine-tuning of N management in order to optimise the use of this element, avoiding losses and reducing environmental hazards. In this study, some results from the literature concerning N fertilisation in coriander are reviewed and, by means of statistical analysis, an attempt is made to derive from them some general suggestions about practices of N fertilisation. In most cases examined, N fertilisation allowed a 10–70% increase in seed yields in co…

Potential Antioxidant and Antiviral Activities of Hydroethanolic Extracts of Selected Lamiaceae Species

2022

Medicinal and aromatic plants (MAPs) are potential sources of natural bioactive phytochemical compounds of an incredible worth for the food industry, such as polyphenols. Lamiaceae medicinal and aromatic plants from Granada’s high plateau, concretely Origanum bastetanum, Thymus zygis gracilis, Thymus longiflorus, Thymus membranaceus and Ziziphora hispanica, were evaluated under different conventional solid–liquid extraction conditions to obtain extracts enriched in bioactive compounds. Phenolic profile was detected by HPLC-QTOF-MS, identifying a high abundance of bioactive constituents. Furthermore, antioxidant and antiviral activities of the mentioned plants were studied as biological prop…

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…
