UNLABELLED BACKGROUND The biological importance of members of genus Ferula promoted us to investigate the leaves of Ferula vesceritensis Coss et Dur. (endemic plant) previously not investigated. This study presents the chemical composition and antibacterial activities of the hydrodistilled oils. RESULTS Volatile components of the leaves of F. vesceritensis have been studied by gas chromato...

The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilli...

Ferula turcica and latialata are two novel endemic species discovered in the Konya Kırşehir provinces of central Anatolian region Türkiye. These new described by morphological, ecological, carpological, phytochemical characteristics phylogenetic analysis. F. morphologically distinct from szowitsiana their habit, stalk terminal umbella, mericarp size, as well profile secondary metabolite markers...

Initial attempts to grow N2-fixing Derxia gummosa autotrophically on H2, C 0 2 , O2 and N2 in a closed system yielded variable results. Poor growth was found to be due to rapid O2 depletion and the requirement for an agar surface. In a closed system, C2H2 reduction assays could not be carried out due to complete consumption of H2. Hence a flow-through culturing technique was developed to supply...
