Agronomic evaluation and chemical characterization of Sicilian Salvia sclarea L. accessions

Clary sage (Salvia sclareaL.), known for its aromatic and medicinal properties, belongs to theLamiaceaefamily. 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. Regarding qualitative characterization, essential oils (EO) were extracted from flowering samples of clary sage. The accessions in the study showed satisfactory adaptation capacity to cropping. The accessions examined belong to the "linalyl acetate" (range 36-43%) chemotype. Test results show good potential for Mediterranean cropping systems, helping to increase the range of medicinal and aromatic species in cultivation.
