Desv. growing wild in Tunisia and its aerial part essential oils (EOs) composition. A total of 37 volatileorganic compounds (96.7%–98.9%) were identified;4 esters, 4 alcohols, 7 hydrocarbons, 12 aldehydes, 5 ketones,1 lactone, 1 organosulfur compound, 2 organonitrogen compounds, and 1 acid. The hydrocarbons form the maingroup, representing 49.5%–84.6% of the total detected volatiles. The main constituent was 2,2,4,6,6-pentamethylheptane(44.5%–76.2%) reaching the highest relative percentages. Forty-two compounds were determined in thetwo fractions of EOs, representing 98.8% and 97.2% of the total oil composition, respectively. The principal componentswere hexadecanoic acid (34.6%), 6-methyl-5-hepten-2-one (18.3%), decanal (15.0%), 6,10,14-trimethyl-2-pentadecanone (13.2%), and n-pentacosane (13%). Micromorphological details of the leaf and stem epidermisusing light microscopy revealed polygonal cells with sinuous walls in the adaxial and abaxial leaf surfaces andnearly rectangular and long ones with linear and thick walls for the stem epidermis. The stomata complexes wereanisocytic in the leaf epidermis and mainly anisocytic and rarely paracytic in the stem epidermis. Non-glandulartrichomes were unbranched and long with an acute apex or short with a convex apex. The glandular ones wereidentified for the first time in this species. They were short-stalked with a large secretory head. The highest stomatalindex (17.02%) was recorded in the abaxial leaf surface. The identification of headspace volatiles and essentialoil compounds can be used to characterize this species, and the various epidermis micromorphologicalfeatures are very useful for biosystematics taxonomic studies within Brassicaceae.展开更多

Knowledge of genetic diversity within a population is important for the conservation of the species. Our aim was to assess the genetic diversity in Draba dorneri Heuff. population (Brassicaceae family)—an endemic plant species of conservative interest using Random Amplified Polymorphic DNA (RAPD) technique. The plant species is strictly protected at national level as well as at international level through “Convention on the Conservation of European Wildlife and Natural Habitats”, Bern, 1979 European Council. In this study, a total of 52 primers were scored initially. A total of 77 repro- ducible bands with an average of 6.41 bands per primer were obtained from the 12 primers selected. A cluster analysis (UPGAMA) was used to generate a dendrogram based on Dice coefficient. We found 67% similarity between the samples from the two analyzed slopes. Comparing with other rare plants species, our data revealed a higher level of genetic diversity in D. dorneri population in Retezat Mountains.展开更多
