Amino Acid Profile, Nutrients Content and Yield of Chickpea (Cicer Arietinum L.) Genotypes
(Scibulcom Ltd, 2015) Dogan, Y.; Doğan, Yusuf; Department of Plant Protection / Bitki Koruma Bölümü
Chickpea has significant amounts of all the essential amino acids except sulphur-containing types. It was found that chickpea is a rich source of protein and minerals. The experiments were conducted in a Randomised Complete Block Design with three replications 2013 and 2014 years in South-Eastern Turkey. A total of fifteen varieties, lines and populations were used as materials. In the study were investigated different parameters such as amino acids of protein, seed yield, protein and fat rate in seed, phosphorus, potassium, calcium, manganese, zinc, copper and iron contents and of seeds. The essential amino acid leucine (8.43 mg/100 g in 2013 and 8.59 mg/100 g in 2014) was found in highest concentration, followed by lysine (7.14 mg/100 g in 2013 and 7.27 mg/100 g in 2014) and phenylalanine (5.99 mg/100 g in 2013 and 6.07 mg/100 g in 2014) in the chickpea. Mineral composition of chickpea genotypes showed that they contribute sufficient amount of Ca, P, K, Cu, Zn and Mg in human diets to meet the recommended dietary allowance. According to the average of two years, the highest grain yield was obtained from Diyar-95 variety with 1618 kg ha(-1), the lowest grain yield was obtained from M-1 local population with 1104 kg ha(-1).

(Journal of the Turkish Chemical Society, Section A: Chemistry, 2020) Yıldırım, Ayfer; Acay, Hilal; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü
This study investigated the adsorption behaviour of two cationic dyes, methylene blue (MB) and malachite green (MG) onto Pleurotus ostreatus, Armillaria tabescens, and Morchella conica mushrooms. The effects of contact time, initial dye concentration, and solution pH (3-11) were also determined. The adsorption on all mushrooms attained equilibrium within 120 min for both MB and MG. To evaluate the experimental kinetics data, the pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetics equations were utilised. The pseudo-first-order kinetic model demonstrated a good fit with all adsorption kinetics. The Langmuir and Freundlich isotherm models were used to analyse the mechanism of the adsorption isotherm. The adsorption equilibrium isotherm was in a good agreement with the Freundlich model. Thermodynamic parameters such as ΔH enthalpy variation, ΔS entropy variation, and ΔG free Gibbs energy variation were calculated at 303-323 K. The results suggested that the Pleurotus ostreatus mushroom was the most suitable adsorbent for both cationic dyes’ removal.

This research was conducted in 2019-20 wheat growing season under rainfall condition of Mardin - Artuklu province. 80 durum wheat landraces originated from Southeast Anatolia and 10 registered durum wheat cultivars were evaluated according to Augmented Trail Design. 20 landraces and 10 cultivars were used for each bloc. We determined large variations in durum wheat landraces for observed traits. Results indicated that mean of observed traits of landraces and varieties were ranged between 229 kg/da - 371 kg/da for grain yield; 1313 kg/kg - 1218 kg/kg for biomass, 18.02 % - 14.94 % for grain protein content. Mean thousand kernel weight of landraces and standard varieties changed between 42.9 g and 40.15 g; heading days ranged from 117.8 to 111 days respectively. According to observed data, landraces had longer heading days and grain stage and also higher grain protein content and biomass compare to standard varieties. Results of this study showed that landraces has high potential to increase biomass and grain protein content and they can be used as a genitor in wheat breeding programs to improving desirable durum wheat genotypes. Observation according to GGE biplot methodology (which-wonwhere) indicated that ST8 (Check) and G80 (landrace) have high values for grain yield, number of seed pers spike, seed weight per spike while G8 (landrace) showed high values for thousand grain weight, length of peduncle, plant height, grain protein content, biomass and heading days. Obtained results from this study indicated that landraces should be preserved for sustainable agriculture activities specially for marginal areas, also they have high diversity and useful traits for national and international wheat breeding programs.

Comparison Of Different Life Stages Of Total, Phospholipid And Triacylglycerol Fatty Acids Of Lucilia Sericata
(ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2021) Kızmaz, Veysi; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Lucilia sericata, which belongs to the Calliphoridae family (Diptera), is used as a debridement tool in open necrotic wounds that do not respond to conventional treatments. Knowing the total, phospholipid (PL), and triacylglycerol (TAG) fatty acid content of L. sericata fly, which is important for health, in its different stages is important both in terms of taxonomy and physiology. After L. sericata samples used in the study were obtained commercially, they were bred under laboratory conditions and then the fatty acids in different stages were analyzed by gas chromatography. Sixteen fatty acids are determined as a result of the analysis. When individual fatty acids are considered, Palmitic acid (16:0), Palmitoleic Acid (16:1n-7), oleic acid (18:1n-9) and Linoleic Acid (18:2n-6) were found to be major ones, while the others are detected in trace amounts. It is determined that, out of total, PL and TAG, saturated fatty acids (SFA) are found at a high percentage in the eggs, monounsaturated fatty acids (MUFA) are the highest in the larvae, and polyunsaturated fatty acids (PUFA) are the highest in fly and pupa. Furthermore, out of total, PL and TAG, ∑PUFA is at a low percentage in the egg and the larval stages. Different results are found at different stages in this study. This may be because fatty acid percentages that change during metamorphosis meet different physiological needs at different phases. © 2021, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

(Turkish Chemical Society, 2024) Umaz, Adil; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Hydrogen is a clean energy carrier that will reduce dependence on fossil fuels and contribute to reducing the harmful effects on the environment resulting from using fossil fuels. Hydrogen is produced by the hydrolysis of sodium borohydride (NaBH4), one of the chemical hydrides, using a catalyst. In this study, Fe3O4@Salicylic acid magnetic nano-catalyst (Fe3O4@SA MNCs) was synthesized using the co-precipitation technique. The structural, physical, and chemical properties of the produced Fe3O4@SA MNCs were characterized by FT-IR, XRD, VSM, SEM, and SEM-EDX methods. At room temperature, the effect on hydrogen production performance was examined in the amounts of Fe3O4@SA MNCs (10, 25, 50, 75, and 100 mg), NaOH (0, 10, 20, and 25 mg), and NaBH4 (25, 50, 100, 150 and 200 mg). The highest hydrogen generation rates (HGR) were obtained using 10 mg Fe3O4@SA MNCs, 150 mg NaBH4, and 0 mg NaOH at room temperature. The obtained HGR value was calculated as 400 mL gcat-1.min-1. Fe3O4@SA MNCs were used for hydrogen production for the first time in this study. This study showed that Fe3O4@SA MNCs exhibit catalytic properties and are a promising, efficient catalyst in hydrogen production from NaBH4.

Neoscytalidium dimidiatum: A newly identified postharvest pathogen of pears and its implications for pome fruits
(Wiley, 2024) Derviş, Sibel; Zholdoshbekova, Sezim; Guney, Inci Guler; Ozer, Goksel; Department of Organic Agriculture / Organik Tarım Bölümü
T & uuml;rkiye is a prominent contributor to pear and diverse pome fruit production. Pear fruit with unusual brown to black spots and rot symptoms observed in public marketplaces in Mardin province have raised concerns regarding postharvest fruit health. The consistent isolation of a fungus from these fruits revealed morphological features indicative of Neoscytalidium dimidiatum. Phylogenetic confirmation of its identity ensued through BLASTn searches targeting, the internal transcribed spacer (ITS) of ribosomal DNA, the partial translation elongation factor 1-alpha gene (tef1), and the partial beta-tubulin gene (tub2). Pathogenicity evaluations were conducted on common pome fruits, namely pears, apples, and quinces, unveiling the susceptibility of all examined fruits to postharvest infection by this emergent pathogen. Furthermore, an investigation was carried out to discern the pathogen's response to varying temperature ranges on pear fruits, revealing that the most pronounced lesions occurred at 30 degrees C, followed by 25 degrees C, 35 degrees C, and 20 degrees C. Conversely, no lesion development was observed at 10 degrees C, 15 degrees C, or 40 degrees C. To the best of our knowledge, this study represents the first report of N. dimidiatum as the etiological agent responsible for postharvest rot in pear fruit. The implications of these findings highlight the potential threat posed by this pathogen to pome fruits postharvest, especially in regions where cold storage facilities are not widely utilized, warranting increased vigilance and preventive measures.

(Scibulcom Ltd., 2015) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf; Department of Plant Protection / Bitki Koruma Bölümü
The objectives of this research were to study the effect of harvesting time and sulphur levels on the yield, protein and mineral nutritional value of chickpea seeds. Three different harvesting times (early, on-time and late) and four sulphur levels (0, 20, 40 and 60 kg ha–1) were used. Yield, protein ratio and mineral nutritional value of chickpea were significantly affected by sulphur and harvest timing. The highest grain yields according to the harvest time were obtained from on-time harvest with 1527 and 1434 kg ha–1 for the first and second years, respectively. The lowest grain yields were obtained from the control plots, whereas the highest values were obtained from the plots given 60 kg ha–1 sulphur. Generally, protein, phosphorus, calcium, magnesium, copper, zinc, and manganese concentrations of the seeds in on-time harvest and 60 kg ha–1 sulphur aplication were found to be greater than in early and late harvested plants. Positive significant relationships were found between harvest time and protein (r = 0.64**), Fe (r = 0.75**) and Zn (r = 0.27*). Positive significant relationships were found between sulphur doses and grain yield (r = 0.44*), protein (r = 0.26*), P (r = 0.71**), K (r = 0.73**), Ca (r = 0.36**), Mg (r = 0.76*), Zn (r = 0.57) and S (r = 0.96*). © 2015, Scibulcom Ltd.

Vegetative Compatibility and Virulence Diversity of Verticillium Dahliae From Okra (Abelmoschus Esculentus) Plantations in Turkey and Evaluation of Okra Landraces for Resistance To V. Dahliae
(Fundacion Romulo Raggio, 2020) Tok, F.M.; Derviş, Sibel; Dervis, S.; Yetisir, H.; Department of Organic Agriculture / Organik Tarım Bölümü
Forty-four V. dahliae isolates were collected from symptomatic vascular tissues of okra plants each from a different field in eight provinces located in the eastern Mediterranean and western Anatolia regions of Turkey during 20062009. Nitrate-nonutilizing (nit) mutants of V. dahliae from okra were used to determine heterokaryosis and genetic relatedness among isolates. All isolates from okra plants were grouped into two vegetative compatibility groups (VCGs) (1 and 2) and three subgroups as 1A (13.6%, 6/44), 2A (20.5%, 9/44) and 2B (65.9%, 29/44) according to international criteria. Pathogenicity tests were performed on a susceptible local okra (A. esculentus) landrace in greenhouse conditions. All isolates from VCG1A and VCG2B induced defoliation (D) and partial defoliation (PD) symptoms, respectively. Other isolates from VCG2A gave rise to typical leaf chlorosis symptoms without defoliation. The obtained data showed that the virulence level of V. dahliae isolates from okra was related to their VCG belongings. Eighteen okra landraces from diverse geographical origins were screened for resistance to VCG2B and VCG1A of V. dahliae. The results indicated that all landraces were more susceptible to highly virulent VCG1A-D pathotype displaying D or PD symptoms depending on their susceptibility levels with a mean disease severity index of 3.52 than to less virulent VCG2B-PD pathotype of V. dahliae displaying PD and ND symptoms with a mean disease severity index of 2.52. Significant differences were observed among the landraces; [however, none of them exhibited a level of resistance. Okra landraces; [Çorum, Hatay Has and Şanlıurfa displayed the lowest level of susceptibility or little tolerance to both D and PD pathotypes. VCG2B of PD was prevailing in the surveyed areas and VCG1A of D was the most virulent of the VCGs identified. Introduction of resistant genotypes to Turkish okra germplasm from different sources and breeding new resistant okra cultivars are critical for the sustainability of okra production. © 2020, Fundacion Romulo Raggio.
