Article Ağır Metal (Ni, Cd ve Cu) Uygulamalarının Andız Otu, Fener Otu ve Sığırkuyruğu Bitkilerinin Büyüme ve Gelişmesi Üzerine Etkisi(2017) Eren, Abdullah; Mert, Mehmet; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBu çalışmada; nikel (Ni), kadmiyum (Cd) ve bakır (Cu) ile kirlenmiş topraklarda andız otu (Inula helenium), fener otu (Physalis angulata) ve sığırkuyruğu (Verbascum thapsus) bitkileri 6 hafta boyunca kontrollü koşullarda yetiştirilerek, bu metallerin topraklardan temizlenebilme olanakları araştırılmıştır. Denemede bitkilerin klorofil düzeyleri, biyokütle üretimi, ağır metal alımı ve indirgenmiş glutatyon (GSH) konsantrasyonları belirlenmiştir. Elde edilen bulgulara göre, bitkilerin dokularında biriktirdiği Ni, Cd ve Cu konsantrasyonlarının toksisiteye neden olacak seviyelere ulaşmadığı tespit edilmiştir. En yüksek Ni içeriği (253 µg bitki-1) fener otu bitkisinin 400 mg Ni kg-1uygulamasından, en yüksek Cd içeriği ise fener otu (46.9 µg bitki-1) ve sığırkuyruğu (54.6 µg bitki-1) bitkilerinde 10 mg Cd kg-1uygulamasından ve en yüksek Cu konsantrasyonu ise fener otu (304 µg bitki-1) bitkisinin 200 mg Cu kg-1uygulamasından elde edilmiştir. Deneme sonucunda fener otu ve sığırkuyruğu bitkilerinin ağır metallerle kirlenmiş toprakların temizlenmesinde kullanma potansiyellerinin olduğu tespit edilmiştir.Article Diyarbakır Yöresindeki Bazı Tarım Topraklarının Hümik Asit İçerikleri ile Eser Elementler Arasındaki İlişkinin Çok Değişkenli İstatistiksel Yöntemlerle Değerlendirilmesi(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2024) Duzgun, Mehmet; Eren, Abdullah; Bilge, Ugur; Ceylan, Ramazan; Selcuk, Ramazan; Duz, M. ZahirThere are important relationships between humic acid (HA) and the bioavailability, reactions and mobility of trace elements in the soil. For this reason, soils are tried to be improved chemically, biologically and physically with HA applications. In this study, the relationship of humic acid contents of 118 agricultural soil samples from Diyarbakir region with some trace elements (Al, As, Ba, Be, Cd, Fe, Mn, Pb, Sb, Sn, Se, V and P) was evaluated by multivariate statistical analysis. After the soil samples were solubilized by the microwave wet digestion method, the element contents were determined with the ICP OES (Inductively Coupled Plasma Optical Emission Spectrometer) device. SRM NIST 2586 was used as SRM (Standard Reference Material) for the accuracy of the method. Recovery values were found between 91.6% and 105.9% as a result of the analysis. Humic acid was extracted from soils by the International Society for Humic Substances (IHSS) method and determined using a shaker and centrifuge device. For the accuracy of the method, it was tested with Humic Acid Sodium Salt (HA-Na). Pearson correlation and partial correlation analysis were applied to the obtained data set. In addition, multivariate statistical analyses such as multiple regression HCA (Hierarchical Cluster Analysis) and PCA (Principal Component Analysis) were applied. Multiple regression analysis was performed according to the Step-wise method. Manganese and P (p< 0.01) were significant when HA was taken as the dependent variable. According to the Pearson correlation coefficient, the correlation between HA and As (r = -0.282**) in soil was negative and significant, while Fe (r = 0.185*), Mn (r = 0.273**)), Sn (r = 0.242*), Se (r = 0.325**) and P (r = 0.315**) were determined as positive and significant. In clustering and PCA analysis, HA, P Mn and Fe were found to be in the same group. The analyses have shown that HA has a positive effect on the plant nutrients in the soil.Article Citation - WoS: 16Citation - Scopus: 15Effects of ZnO Nanoparticles and Ethylenediamine-N,N′ Acid on Seed Germination of Four Different Plants(Wiley-VCH verlag GmbH, 2019) Dogaroglu, Zeynep Gorkem; Eren, Abdullah; Baran, M. FiratThe release of nanoparticles and biodegradable chelating agents into the environment may cause toxicological and ecotoxicological effects. The aim of this study is to determine the ecotoxic effects of zinc oxide (ZnO) nanoparticles and ethylenediamine disuccinic acid (EDDS) on most cultured four plants. The durum wheat, bread wheat, barley, and rye are exposed to 5 mL 10 mg L-1 ZnO nanoparticles and 10 mg L-1 EDDS in the seed germination stage. Results show that these different plant species have different responses to ZnO nanoparticles and EDDS. The germination percentage of bread wheat and rye decreases in the application of ZnO nanoparticles while the germination of durum wheat and barley increases as much as in radicle elongation and seedling vigor. While ZnO treatment causes a decrease in bread wheat and rye germinated rat in the range of 33-14.3%, respectively, there is no change in germination rate of these plants at EDDS treatment. In addition, EDDS treatment positively affects barley germination rate. In conclusion, it is clear that ZnO nanoparticles have more toxic effects on bread wheat and rye than EDDS, while barley is positively affected by ZnO nanoparticles and EDDS.Article INVESTIGATING ANTIMI CROBIAL ACTIVITY OF SILVER NANOPARTICLES PRODUC ED THROUGH GREEN SYN THESIS USING LEAF EXTRACT O F COMMON GRAPE ( VITIS VINIFERA(2019) Acay, Hilal; Baran, Mehmet Fırat; Eren, Abdullah; 09.03.

Mardin Artuklu University / Mardin Artuklu ÜniversitesiIn this study, a direct approach to fabricating silver nanoparticles (AgNPs) via the leaf extract of common grape (Vitis vinifera) has been demonstrated. The produced particles were found with a maximum wavelength of 452.47 nm, spherical shape and the crystal size of 18.53 nm through UV-Visible spectrophotometry, XRD (X-ray diffraction) and SEM (Scanning electron microscopy) characterization methods. Furthermore, the functional groups involved in the reduction were specified with FTIR (Fourier transform infrared spectroscopy), the elemental compounds were identified with EDX (Energy dispersive X-Ray spectroscopy) and the degradation points were determined with TGA-DTA (Thermal gravimetric analysis) methods. AgNPs were found to be effective against hospital pathogens, namely Gram-negative Escherichia coli ATCC 25922, Gram-positive Staphylococcus aureus ATCC 29213 and Candida albicans fungus at the concentrations of 0.314, 0.078 and 0.334 g mL-1, respectively.Article Kızıltepe Yöresinde Buğday Tarımı Yapılan Toprakların Bazı Verimlilik Durumlarının Belirlenmesi(GAZİOSMANPAŞA BİLİMSEL ARAŞTIRMA DERGİSİ, 2019) Eren, Abdullah; 16.01.

Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiIn this study, the use of Rosmarinus officinalis was investigated to clear soil contaminated with Cd. The soil sample for pot experiment is taken from the old municipal waste storage in Mardin. The pot experiment conducted in the greenhouse. Increasing dose of Cd (0-5-10-20 mg kg-1 as 3CdSO4.7H2O form) and 0.005 mM citric acid applied to the soil and all pots were incubated for 30 days. The fertilizer (200 mg N kg-1) applied before seedling and then plant seedlings transferred to the pots. The plants were grown for 45 days in the greenhouse. After harvest Cd, N, P, K, Mn, Fe, Cu, and Zn concentrations of plant samples were determined in ICP-MS. The highest Cd content (8.31 μg plant-1) was obtained in 20 mg Cd kg-1 treatments. The result of the experiment was shown that the Rosmarinus officinalis was not suitable for pyhtoextraction of Cd-contaminated soils.
