Öğe Determination of nutrient content of Gagea bohemica (Liliaceae) in Turkey(Springer, 2023) Eskin, Bülent; Demir, Aynur; Rashidi, AdelehMineral nutrients are essential for the growth and survival of a plant. In particular, bulbous plants such as Gagea bohemica (Zauschn.) Schultes & Schultes f. store nutrients and use them in metabolic activities during dormancy. The main aim of the present research is to reveal the micro- and macronutrient contents of G. bohemica. The soil and plant (bulbs, stem, and leaf parts) samples were taken from the southeast of Aksaray in Turkey at an altitude of 1320 m above sea level in April 2021. The amount of nutrients (Zn, S, P, Ni, Mn, Mg, K, Fe, Cu, Ca, Ba, and Al) in these samples were determined by ICPMS. Afterwards, these data were analyzed statistically. Zn, Fe, K, and Ca values in soil were within reference values, whereas Al (65,000 ± 1000–75,000 ± 3000 mg/kg), Cu (20 ± 2–46 ± 0.1 mg/kg), Mg (15,000 ± 1000–21,000 ± 1000 mg/kg), Mn (606 ± 2–751 ± 24 mg/kg), and Ni (75 ± 7–100 ± 10 mg/kg) values were above. Our results indicate an accumulation of nutrients in the soil where G. bohemica grows. Similarly, the concentrations of Zn, K, Cu, and Ca in the bulbs of the plant were among the reference values, while Al (14,900 ± 500 mg/kg), Fe (15,700 ± 200 mg/kg), Mg (7600 ± 300 mg/kg), Mn (321 ± 15 mg/kg), and Ni (81 ± 1 mg/kg) ratios were higher than optimal. Additionally, we found that G. bohemica effectively accumulates Al, Fe, Mg, and Ni in its shoot tissues. Monitoring this plant in terms of macro and micronutrients will provide more detailed information about its ecological features and habitat properties. In this way, it will be possible to carry out the cultivation of the species in suitable conditions and effective species protection and ensure sustainability.Öğe Heavy metal (Cr, Cu, Ni, Pb, and Zn) contents of endemic Salvia halophila plants around Lake Tuz(Toprak Gübre ve Su Kaynakları Merkez Araştırma Enstitüsü, 2022) Baysal Furtana, Gökçen; Demir, Aynur; Tekşen, Mehtap; Rashidi, Adeleh; Tıpırdamaz, RukiyeHeavy metals occur naturally in ecosystems at varying concentrations. However, heavy metal sources that have emerged in present-day mainly due to human influence, i.e. industrial activities, agricultural waste, pesticides, use of fossil fuels and traffic, have included a part of heavy metals in the ecosystem. Lake Tuz, together with the entire lake surroundings, water beds and important steppe areas, was declared Turkey’s Specially Protected Area (SPA) in 2001. Our aim in this investigation was to determine the levels of heavy metals such as Chrome (Cr), Copper (Cu), Nickel (Ni), Lead (Pb) and Zinc (Zn) in endemic Salvia halophila grown in different areas of Lake Tuz. The results of the heavy metal contents analyzed at the plant were compared with the international standard levels of heavy metals. The consequences displayed that differing extents of heavy metals are accumulated in S. halophila. The results obtained differed in accordance with the collection time and localities. When the outcomes are appraised, it is achievable to say that Pb is higher than the standard values. The findings of this investigation are the first reported results for this endemic S. halophila species that grows naturally at Lake Tuz and are important as they are newly discovered results.Öğe Investigation of Alkanna Orientalıs Var. Orientalis (l.) boiss in terms of macro and micro nutrient elements: a case study in Aksaray(Pakistan Botanical Society, 2022) Demir, Aynur; Eskin, Bülent; Rashidi, AdelehIn this study, Alkanna orientalis var. orientalis (L.) BOISS was analyzed to determine its nutritional contents and phytoremediation potential. The plant and soil samples were collected from Mahmutlu Hill in Aksaray in May (2019). The mineral contents of soil and plant samples (Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Ni, P, S, Zn) were determined by ICP-MS, and the obtained data were statistically analyzed and evaluated. K value in the soil was below the optimal value whereas Mg, Mn and Ni values were above the optimal values. On the other hand, the concentrations of Al, Ca, Cu, K, Mn and Zn in the plant were around the optimum values, while Fe, Mg, Ni were above. The results of the analysis showed that Fe and Ni concentrations were at a toxic level. Therefore this plant can be used in phytoremediation studies.Öğe Investigation of mineral nutrient and heavy metal accumulation status of senecio Vernalis Waldst. & Kit. collected from different habitats of Aksaray/Turkey(Taylor & Francis, 2022) Demir, Aynur; Eskin, Bülent; Rashidi, AdelehIn this study, Senecio vernalis Waldst. & Kit. was analyzed to determine a phytoremediation potential and nutritional contents are estimated. The plant and soil samples were collected between Karaoren and Karkin villages in Aksaray in May (2021). The mineral contents (Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Ni, P, S, Zn) of the collected plant and soil samples were determined by ICP-MS and the obtained data were analyzed statistically. In soil, Ca, Fe, K and Zn values were in the optimal value whereas Al, Cu, Mg, Mn and Ni values were above the optimal values. This means that there is bioaccumulation of these heavy metals (Al, Cu, Mg, Mn and Ni) in the soil. Likewise, the concentrations of Ca, Cu, K, Mn and Zn in the plant were among the optimum values, while Al, Fe, Mg, and Ni ratios were higher than the quantification limit. The rate of these metals in the roots and other shoots of the plant are higher than in the soil. Our results showed that Senecio vernalis is a very good accumulator of Fe, Mg and Ni, and also the phytoextraction and phytoremediation ability of the plant is high.
