İmpact Of Genotype And Nitrogen Fertilizer Rate On Yield And Nitrogen Use By Oat (Avena Sativa L.) İn Turkey
(Soc Field Crop Sci, 2012) Maral, Hasan; Dumlupınar, Ziya; Dokuyucu, Tevrican; Akkaya, Aydın
Efficient nitrogen (N) use is one of the most crucial issues for crop management in developing countries. Since Turkish agricultural practices tends to use lower inputs of N fertilizers, a field trial was carried out in 2007-08 and 2008-09 cropping years to determine response of six oat genotypes (Seydisehir, Apak, Yesilkoy-330, Amasya, Checota and Yesilkoy-1779) to three N rates (0, 100 and 200 kg ha(-1)). According to the results, differences between the years were significantly important for all investigated traits except soil nitrogen content at planting (NCP), nitrogen content at maturity (NCM) and nitrogen accumulation in grain (NAG). Genotypes significantly varied for all traits except NCP, nitrogen in grain (NG) and NAG. However, differences among N rates were significant for all traits except NCP.Among the genotypes Checota had the highest nitrogen use efficiency (NUE) and grain yield (GY) (20.6 kg kg(-1) N and 2590 kg ha(-1), respectively).

(Brill Academic Publishers, 2022) Ulupınar, Süleyman; Maral, Hasan; Özbay, Serhat; Gençoǧlu, Cebrail; Türk Baydır, Ayşegül; Şebin, Engin
Natural herbal products are widely used by athletes to reduce the immune suppression caused by intensive exercise. This study aimed to determine the effects of the essential oils Origanum dubium, Origanum vulgare subsp hirtum, and Lavandula angustifolia, which belong to the Lamiaceae family, on immune cells in athletes. Thirty-four trained men (age: , height: , body mass: ) were randomly assigned to one of three experimental groups or the control group. Leukocytes and their subgroups were measured before and after a 14-day essential oil intervention and following an intensive exercise session. The main findings indicated that essential oils isolated from O. dubium (; ; ; increase), O. vulgare subsp hirtum (; ; ; increase), and L. angustifolia (; ; ; increase) increased lymphocyte counts, thus maintaining baseline levels despite decreased post-exercise lymphocyte counts. Additionally, the post-exercise lymphocyte count was lower than that after the intervention (; ) but higher than at baseline (; ) in the O. vulgare subsp hirtum group. The lower post-exercise lymphocyte counts of the control group compared with those after the 14-day period (; ) and baseline (; ) supported the experimental group results. However, our findings revealed that essential oil interventions had no significant effect on neutrophil counts, but the intensive exercise intervention increased the neutrophil counts in all groups. No significant change was identified in the other subgroup counts following the essential oil intervention or post exercise. Therefore, the results of this study indicate that these plants, especially O. vulgare subsp hirtum, can be used to alleviate the immune suppressive effects of intense exercise in athletes.

(Universidad de Concepcion, 2022) Soltanbeigi, Amir; Maral, Hasan
Echinacea purpurea is cultivated around the world due to its unique pharmacological effects. The aerial parts of the plant, especially its flowers, contain a wide variety of beneficial bioactive substances. The objective of this study was to evaluate the effect of different nutrient applications on the growth parameters, essential oil yield, and compounds of Echinacea purpurea L. Moench in Afyonkarahisar/Turkey. The experiment was conducted over a 3-year period (2016-18), including four experimental treatments (F0: control, F1: 75 kg ha-1 N; F2: 150 kg ha-1 N; and F3: 75 kg ha-1 N + foliar fertilizer). As a general result of five cuttings, F2 and F3 had a positive effect on agronomic yield. F2 and F3 recorded the highest plant height (91 and 90 cm, respectively) and yields for fresh bud (578 and 543 kg ha-1), dry bud (118 and 112 kg ha-1), fresh flower (8,595 and 7,449 kg ha-1), dry flower (2,021 and 1,745 kg ha-1), fresh herb (32,645 and 29,291 kg ha-1), dry herb (8,746 and 7,745 kg ha-1) and essential oil (4.55 and 3.57 L ha-1). Sesquiterpene hydrocarbons were the most abundant chemical group compound of E. purpurea essential oil. Germacrene D (20.4-50.6%) was the predominant constituent, recording its maximum level in F1. Other major compounds were β-pinene, β-myrcene, α-humulene, δ-cadinene, spathulenol, and α-cadinol. The application of 150 kg ha-1 N as well as the combined use of 75 kg ha-1 N and foliar application of macro and micro elements resulted in the highest agronomic yield and essential oil production. © 2022 Universidad de Concepcion.

(2022) Maral, Hasan
Satureja (Lamiaceae) species are aromatic plants used to produce essential oil and aromatic water in the Mediterranean region of Turkey, and Satureja cilicica P.H. Davis is an endemic species for Turkey. This study was conducted to determine the effects of diurnal variability on essential oil (EO) content and components of Satureja cilicica in the Ermenek district/Turkey in 2021. During the day, four different harvest times were considered as follows: 7:30 and 10:30 a.m., 01:30 and 4:30 p.m. at the flowering stage. The aerial parts of harvested plants were dried in the shade. The greatest and least EO contents of S. cilicica aerial parts were obtained at 4:30 p.m. (0.61%) and 1:30 p.m. (0.32%), respectively. The results of the analysis revealed that the major components of essential oils of S. cilicica are p-cymene (19.24-40.04%), carvacrol (16.42-29.59%), thymol (10.04-19.34%), γ-terpinene (4.92- 12.94 %) and linalool (4-42-6.53%). In this study, it was determined that the best harvest time for optimum essential oil content and chemical properties was the cool hours of the day.

(Bangladesh Botanical Society, 2022) Maral, Hasan
Glaucosciadium cordifolium is distributed in Central Anatolia, the Mediterranean region and Northern Cyprus. It has been used in traditional medicine as an aphrodisiac. In the present study the essential oil content, oil components and antioxidant properties of G. cordifolium plant collected from the natural location were determined. It was observed that the essential oil content and oil components obtained from fresh and dry plant parts differed. The highest essential oil ratio (1.40%) was obtained from the dried leaf, while the lowest ratio (0.15%) was obtained from the fresh stem. Analysis results showed that the main components of the essential oil were 1-phellandrene (9.23-34.08%), α-pinene (10.23-31.95%), dl-limonene (10.39-22.21%) and cis-ocimine (6.84-12.45%). In addition, some of these main components were higher in dry plant parts, while others were higher in fresh plant parts. In terms of antioxidant properties, higher values were obtained in dry plant parts as well as in the essential oil ratio. While the maximum radical scavenging activity values (32.70%) were obtained in the dry stem, the lowest value (16.63%) was obtained in fresh leaves. © 2022 Bangladesh Botanical Society.

A novel fluorescent sensor based on an enzyme-free system for highly selective and sensitive detection of glyphosate and malathion in real samples
(Elsevier B.V., 2023) Aydın, Ziya; Keskinateş, Mukaddes; Akın, Şeyma; Keleş, Hülya; Keleş, Mustafa
Malathion (Mal) and glyphosate (Glyp) are widely used organophosphorus pesticides to prevent or control insects and weed in agriculture. Unfortunately, the extensive and frequent commercial use of these compounds on farmland has caused their presence as residues in crops and livestock. Therefore, the design of new sensors with enhanced analyte selectivity and sensitivity is critical in this field. Here, we developed an optical sensor for the detection of malathion and glyphosate. The sensor, N,N-dimethyl-4-(3-(pyrazin-2-ylimino)prop-1-en-1-yl)aniline (CNP), was synthesized in a one-step reaction by condensation of 4-(dimethylamino)cinnamaldehyde with 2-aminopyrazine. CNP gives a rapid color change, absorbance and fluorescence response to Glyp and Mal in the presence of the metal ions and pesticides tested in the working system. The binding stoichiometry between the sensor and the pesticides (Glyp and Mal) was investigated by some spectrophotometric methods and the sensing mechanisms were eludicated by NMR titration experiments, suggesting that CNP responds to Glyp via H-bonding and to Mal via the coordination. The sensor has a high selectivity and rapid response to the pesticides (Glyp and Mal) with low detection limits. The sensor was also successfully used to monitor the pesticides in real samples; Mal in apple and tap water samples, and Glyp in potato, tap water and soil samples.
Two novel enzyme-free colorimetric sensors for the detection of glyphosate in real samples
(Academic Press Inc., 2022) Aydın, Ziya; Akın, Şeyma; Çenet, Esma Nur; Keskinateş, Mukaddes; Akbulut, Abdullah; Keleş, Hülya; Keleş, Mustafa
The intensive use and accumulation of glyphosate cause many environmental and ecological problems. There is an urgent need for an effective detection method for glyphosate. Many studies in the literature determine glyphosate by an enzyme-based method, requiring appropriate temperature, pH, substrate and ionic strength. In this study, we presented a simple enzyme-free reaction system. Two new simple Schiff base derivatives, 4-(((3-chloropyridin-4-yl)imino)methyl)-N,N-dimethylaniline (BNP-Cl) and 4-((3-((3-chloropyridin-4-yl)imino)propenyl)-N,N-dimethylaniline (CNP-Cl), were prepared by combining a pyridine moiety with a cinnamaldehyde or a benzaldehyde moiety. The pyridine moiety contains a chlorine atom, and this chlorine atom is replaced by the nitrogen or oxygen of glyphosate (Glyp) in ACN/Tris buffer (pH=8.14, 10 mM, v/v 2:1). This binding caused color changes ranging from colorless to yellow for BNP-Cl and yellow to orange for CNP-Cl. The sensors BNP-Cl and CNP-Cl have a rapid and excellent selectivity for glyphosate with low detection limits (1.78 µM for BNP-Cl and 1.60 µM for CNP-Cl). The sensors were also successfully applied to detect Glyp in real samples such as soil, tap water, and potatoes.
A highly selective optical sensor for the detection of cyanide ions in aqueous solution and living cells
(Elsevier B.V., 2022) Yılmaz, Bahar; Keskinateş, Mukaddes; Aydın, Ziya; Bayrakçı, Mevlüt
A fluorogenic naphthalene based receptor (NFS) has been successfully generated by preparation from 3-amino-2-naphthol and 2-hydroxy-1-naphthaldehyde, it was then characterized. Optical and colorimetric properties of the receptor (NFS) in terms of cyanide (CN-) ions were investigated by several methods including naked-eye detection, UV–vis spectrophotometry and fluorescence spectroscopy. A visual color change from yellow to orangish-pink was observed upon interaction of the receptor with cyanide (CN-) ions in solution, while no color change appeared upon addition of the other anions tested. The detection limit of NFS was calculated as 0.21 µM without any interaction with other anions tested which is lower than that described by the World Health Organization for CN– ions in drinking water. It can be concluded that the receptor (NFS) was sensitive and rapid enough for the detection of CN- ions in solutions. The interaction between the receptor and CN– ions was also investigated by 1H NMR titration, MALDI-Tof mass spectrometry, and FTIR-AR spectroscopy. NFS was also applied to the bio-imaging of human epithelial cell line (HEK 293) and the cell imaging studies demonstrated that the receptor was capable of detecting cyanide ions in living cells.
Effect of Origanum dubium, Origanum vulgare subsp. hirtum, and Lavandula angustifolia essential oils on lipid profiles and liver biomarkers in athletes
(De Gruyter Open Ltd, 2021) Maral, Hasan; Uluplnar, Süleyman; Türk Baydlr, Ayşegül; Özbay, Serhat; Altınkaynak, Konca; Şebin, Engin
This study aims to determine the effects of essential oils of Origanum dubium (DUB), Origanum vulgare subsp. hirtum (HIR), and Lavandula angustifolia (LAV) on lipid profiles and liver biomarkers in athletes. Thirty-four trained athletes were randomly assigned to one of three experimental groups or the control group (CON). The concentrations of serum lipids and liver biomarkers were assessed before and after the 14-day essential oil intervention. Gas chromatography-mass spectrometry analysis showed 68.0 and 82.1% carvacrol in DUB and HIR, respectively, and 34.50% linalyl acetate and 33.68% linalool in LAV essential oils. One-way analysis of covariance (ANCOVA) indicated a significant difference (p = 0.001) among the groups for high-density lipoprotein cholesterol (HDL-C) when the associated preintervention values were used as a covariate. The related pairwise comparisons revealed that DUB (p = 0.001) and HIR (p = 0.024) had greater HDL-C values than CON. From the two-way ANOVA, an interaction between time (before vs. after) and the groups (DUB vs. HIR vs. LAV vs. CON) was found for HDL-C (p = 0.030). Findings indicated a significant increase in DUB (p = 0.0001) and HIR (p = 0.010) for HDL-C, and there was a significant decrease in DUB (p = 0.023) for low-density lipoprotein cholesterol. However, there was no difference in total cholesterol, triglycerides, and all liver biomarkers.
Determination of chemical component of essential oil of Origanum dubium plants grown at different altitudes and antifungal activity against Sclerotinia sclerotiorum
(John Wiley and Sons Inc., 2021) Türkmen, Musa; Kara, Merve; Maral, Hasan; Soylu, Soner
The aim of this study was to determine effect of altitude on the yields, composition, and antifungal activities of the essential oil isolated from Origanum dubium plant populations collected at four different altitudes. The essential oil yield, the content of four compounds and antifungal activities against Sclerotinia sclerotiorum were found to vary in relation to the different altitudes examined. According to the GC-MS analysis, carvacrol (46.51%–85.65%), linalool (0.24–48.37), p-cymene (1.89%–7.89%), and γ-terpinene (0.28%–6.31%) were determined as major compounds of essential oils of the plants collected from different altitudes. Altitude seems one of the factors that affected the quantity and quality of the essential oil of O. dubium. A significant correlation between the amount of carvacrol, p-cymene, and antifungal activities was determined. The essential oil of plant having the highest content of carvacrol (85.65%) showed the strongest antifungal activity against S. sclerotiorum at relatively very low concentration used (0.75 µl petri−1). Practical applications: The essential oil yields, the chemical compositions and antifungal activities against Sclerotinia sclerotiorum were found to vary in relation to the altitudes where plants grown. Since the yield, chemical composition, and biological activities was affected, altitude seems to be an important factor that should be considered. To the best of our knowledge, this is the first study reporting antifungal activities of essential oil of Origanum dubium against devastating plant fungal disease agent S. sclerotiorum.

(Tubitak Scientific & Technical Research Council, 2021) Çeçen, Ömer; Özcan, Taner
In this study, a member of sect. Teucrium, hitherto undescribed as a new species, was analyzed based on morphological and micromorphological features and molecular findings. The closest species of the new species were defined according to leaf morphology via morphological characters. Leaf, stem, and nutlet trichome types were obtained and compared with resembling species. Moreover, two different DNA region sequences were used to evaluate its proper phylogenetic position in the section. The new species was described as Teucrium turcicum Cecen & Ozcan based on the results of using different approaches. According to our observations, flower color, leaf structure, and shape were the main distinctive morphological characters, leaf and nutlet trichomes were separative and informative, and nrITS DNA data had more informative characters than chloroplast DNA region data (trnL-F and rpl32) to determine phylogenetic relationship of the new species and its close relatives in sect. Teucrium.

(Lithuanian Research Centre Agriculture & Forestry, 2012) Dumlupınar, Ziya; Dokuyucu, Tevrican; Maral, Hasan; Kara, Rukiye; Akkaya, Aydın
In a two-year study, 196 Turkish oat landraces and 3 standard cultivars ('Checota', 'Faikbey' and 'Seydisehir') were evaluated for morphological traits: germination rate, stem diameter, upper inter-node length, plant height, flag leaf width, flag leaf length, single plant biomass, lodging severity and barley yellow dwarf virus, and for phenological traits: vegetative period, grain filling period and, days to maturity. According to two years' data, all traits differed for years except germination rate. Genotypes varied for upper inter-node length, stem diameter, plant height, flag leaf width, vegetative period, grain filling period and days to maturity. In addition, year x genotype interaction was significant for stem diameter, flag leaf width, vegetative period, grain filling period and days to maturity. Traits such as flag leaf length, flag leaf width, days to maturity, vegetative period, single plant biomass and germination rate were more promising ones as selection criteria. However, lodging severity, plant height, barley yellow dwarf virus, upper inter-node length and grain filling period were more important for negative selection. Results indicate that, El A56, E7, E55, A17, E38, A40, A63, A25, A69, A26, A83, A1, A2, K11. K9, K3, K53, K30, K1 K2, K7, K5, K8, K48 and K4 were some of the genotypes in the right quadrants of the biplot with vegetative period, days to maturity, flag leaf width, flag leaf length, germination rate, single plant biomass and stem diameter traits.
