This study is focused on ethnobotanical usages of wild plants growing within the Afyonkarahisar province districts of Sinanpaşa, Hocalar and Dazkırı. Ninety local informants in 11 villages were interviewed. A total of 129 different usages of wild plants in the study area were recorded. Out of 650 plant species commonly present, 93 plant taxa (14.3%) belonging to 43 families were used for medicinal (52 citations), foodstuff (37 citations), fodder (14 citations), dye (six citations), firewood (five citations), construction materials (four citations) and miscellaneous purposes (11 citations). At least 15% of the information regarding ethnobotanical uses of wild plants was obtained by showing herbarium voucher samples to the informants. It was noted that Sideritis leptoclada and Verbascum stenostachyum are endemic to Turkey and their endangered status has markedly increased in recent years because of increased collecting for ethnobotanical purposes. Informants indicate that members of the younger generation have a much reduced interest in ethnobotanical knowledge and that this is a danger to the continued use of local plants.
This study investigates ethnobotanical uses of wild plants found on Honaz Mountain and its vicinity in Denizli Province in the middle Aegean region of Turkey. Eighty-one persons from 13 villages and six townships were interviewed. Nine hundred and sixty-four species, belonging to 60 plant families, were identified for which 381 different uses were recorded. Informants reported ethnobotanical uses for 19% of the identified species (184 out of 964): food (65), fodder (111), medicinal (119), firewood (28), handicrafts (16) and various other purposes (26). Medicinal tar production was particularly noted.
This study was undertaken to evaluate genotoxic potential of Thermopsis turcica aqueous extracts on the roots of onion bulb (Allium cepa L.) by comet assay and random amplified polymorphic DNA technique. The Allium root growth inhibition test indicated that the EC 50 and 29EC 50 values were 8 and 16 mg/ml concentrations of T. turcica aqueous extracts, respectively. The negative control (distilled water), positive control (methyl methane sulfonate, 10 mg/l) and 8 and 16 mg/ml concentrations of T. turcica extracts were introduced to the roots of onion bulbs for 24 and 96 h. The root growth, DNA damage in root cells and randomly amplified polymorphic DNA (RAPD) profiles of root tissue were used as endpoints of the genotoxicity. The comet assay clearly indicated that dose-dependent single strand DNA breaks in the root nuclei of onions were determined for the treatment concentrations of T. turcica extracts. In comparison to RAPD profile of negative control group, RAPD polymorphisms became evident as disappearance and/or appearance of RAPD bands in treated roots. The diagnostic and phenetic numerical analyses of RAPD profiles obviously indicated dosedependent genotoxicity induced by Thermopsis extracts. In conclusion, the results clearly indicated that water extract of T. turcica has genotoxic potential on the roots of onion bulbs as shown by comet assay and RAPD technique.
This report deals with micropropagation of the critically endangered and endemic Turkish shrub, Thermopsis turcica using callus, root and cotyledonary explants. Callus cultures were initiated from root and cotyledon explants on MS medium supplemented with 0.5-20 µM NAA or 2,4-D. The root explants were found to be better in terms of quick responding and callusing percentages as compared to the cotyledons. Organogenic callus production with adventitious roots and shoots were obtained on MS medium with only NAA. The calli obtained with NAA, root and cotyledonary explants were cultured with BA and kinetin (2-8 µM) alone or in combination with a low level (0.5 µM) of 2,4-D or NAA. The best regeneration of shoots from root explants was observed on hormone-free MS medium. NAA with BA or kinetin in the medium improved shoot induction from the calli obtained with NAA. Maximum percentage of shoots (93.3%), maximum number of shoots (6.2) and maximun length of shoots (8.22 cm) were achieved from cotyledonary explants at 4 µM BA and 0.5 µM NAA. The presence of 0.5 µM or higher levels of 2,4-D in shoot induction medium inhibited the regeneration in T. turcica explants. 83% of in vitro rooting was attained on pulsed-IBA treated shoots. The regenerated plants with well developed shoots and roots were successfully acclimatized. Application of this study's results has the potential to conserve T. turcica from extinction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
