Öğe The Incidence Rate of White Rot (Sclerotinia sclerotiorum (Lib.) de Bary) Disease in Sunflower Cultivation Areas in Konya and Aksaray Provinces and its Pathogenic Potential(Selçuk Üniversitesi, 2021) Koçak, Raziye; Boyraz, NuhThis study was conducted between June-September 2017-2018 in sunflower cultivation areas of Konya and Aksaray to determine the incidence rate of white rot disease and its pathogenic potential and to identify the disease agent Sclerotinia spp., Surveys were carried out 11,750 decares in total from Karatay, Altınekin, Cihanbeyli, Karapınar, Kadınhanı and Çumra districts of Konya province and 3000 decares in total from Centre of Aksaray (Hırkatol and Topakkaya village) and Eskil districts of Aksaray province. In the study, it was determined that the isolates obtained from diseased plants belong to Sclerotinia sclerotiorum (Lib.) de Bary. Although the disease was not seen in the first year in Konya, the disease rate in Altınekin district was determined as 9.38% in the second year. As a result of the survey studies, the disease rate in the Center of Aksaray in 2017 and 2018, respectively, was 2.83% and 3.97%; in Eskil, while no disease was occurred in the first year, it was determined at a rate of 4.16% in 2018. In the pathogenicity tests carried out with sunflower seedlings using approximately 20% of the isolates, it was found that the disease severity of the isolates varied between 56% and 66% and the difference between the disease severity and scale values of the isolates was statistically significant (P <0.05). Aksaray / Hırkatol was found to be the most virulent isolate in the pathogenicity test.Öğe Uluborlu ve Senirkent Havzasında Meyve Yetiştiriciliğinin CBS ile Değerlendirilmesi(Selçuk Üniversitesi, 2018) Yılmaz, Yelda TuğbaDiğer birçok tarım ürünü gibi insan beslenmesinde önemli bir yeri olan meyve yetiştiriciliği tarımsal faaliyetler içinde önemli bir yer tutmaktadır. Meyveciliğin her geçen gün artan öneminden dolayı ülkemizde de birçok meyve yetiştirilmektedir. Öyle ki, Türkiye başta konum olmak üzere sahip olduğu coğrafi özellikler dolayısıyla birçok meyve çeşidinin yetiştirildiği ülkelerden biridir. Özellikle ılıman iklim meyve türlerinin zenginliği bu durumun göstergesidir. Diğer yandan, Türkiye birçok meyvenin ana vatanı özelliğindedir. Ayrıca Türkiye arazisi mevcut durumdan daha fazla üretim yapmaya uygun olduğu bilinmektedir. Dünya üzerinde yetiştirilen otuzdan fazla meyve türü ülkemizde yaygın olarak yetiştirilmektedir. Böylece meyveler hem doğrudan insanların tüketiminde hem de sanayi hammaddesi olarak kullanılmaktadır. İklim başta olmak üzere diğer koşulların da elverişli olması dolayısıyla meyveler özellikle bazı bölgelerde daha yoğun olarak yetiştirilmektedir. Ülkemizdeki diğer tarımsal faaliyetlerde olduğu gibi meyvecilik de doğal ve beşeri bazı şartlardan etkilenmektedir. Başta yağış, sıcaklık gibi ikim özellikleri olmak üzere, toprak çeşidi, eğim durumu gibi özellikler de meyve yetiştiriciliğini etkilemektedir. Özellikle geç donlar olarak bilinen don olayları bahar mevsiminde erken çiçek açan meyvelere önemli ölçüde zarar vermektedir. Birçok yörede halen ticari olmaktan çok geçimlik olarak meyveciliğin yapılması yanında zararlılarla yeterince mücadele edilememesi ve pazar şartlarında yaşanan çeşitli sorunlar da meyveciliği etkileyen bazı beşeri koşullar olarak belirtilebilir. Türkiye’de meyve üretiminde bu çeşitliliğin gözlendiği önemli alanlardan birisi de Isparta ve çevresidir. Gerek yetiştirilen meyve çeşitliliği bakımından gerekse bu ürünlerin kalitesi bakımından Isparta ili Türkiye pazarında önemli bir yer tutar. Araştırma alanında, başta elma, kiraz ve kayısı olmak üzere çeşitli meyve yetiştirilmekte hem ülke içine hem de ülke dışına pazarlanmaktadır. Bu çalışmada Isparta ili sınırları içinde yer alan Uluborlu ve Senirkent havzasında yetiştirilen başlıca meyvelerin CBS ile analizi yapılacaktır. Çalışmada veri temini açısından Uluborlu ve Senirkent ilçelerinin idari sınırları dikkate alınmıştır.Öğe Using AHP and PROMETHEE multi-criteria decision making methods to define suitable apiary locations(TAYLOR & FRANCIS LTD, 2020) Sari, Fatih; Kandemir, Irfan; Ceylan, Durmus Ali; Gul, AzizBeekeeping activities have a rapidly increasing importance due to their derived products and their contributions to human health, biodiversity, agriculture, and pollination. Moreover, beekeeping can play a major role in supporting rural development and bringing the benefits of sustainable developments and productivity. Thus, the decision on correct apiary locations via suitability analysis techniques seems essential to sustain and increase the yield and efficiency. However, this decision-making process requires a large number of parameters including the topography of the field surrounding environment and climate conditions. At this point, Multi Criteria Decision Analysis techniques can provide efficient solutions for decision making on suitable apiary locations. In this study, suitable apiary site selection analysis for beekeeping activities via Analytical Hierarchy Process (AHP) and The Preference Ranking Organization Method for Enrichment of Evaluations (PROMETHEE) methods was proposed for Konya city located in Central Anatolia as a pilot application. Aspect, elevation, slope, flora, water resources, roads, railroads, settlements, electricity lines, buildings, precipitation, and natural disaster area criteria were assessed to generate beekeeping suitability for apiaries. The restrictions and requirements of beekeeping activities were specified considering expert beekeeper decisions and recent studies for the study area. The AHP and PROMETHEE suitability maps were validated with existing 461 apiary locations to be able to determine the reliability and applicability.Öğe Determination of melatonin deprivation impact on sepsis with acute phase reactants(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2020) Akbulut, Hatice Feyza; Vatansev, Hüsamettin; Sekmenli, TamerBackground: The aim of the present study is to determine the association of melatonin hormone level on CRP, Total Antioxidant Status, Leukocyte, Procalcitonin, and Malondialdehyde, all acute phase reactants in the dark and light cycle of rats with sepsis model. Materials and methods: In this study, 54 rats were divided into three groups. Whereas the first and third groups had a 12 h dark-light cycle, the second group was exposed to light for 24 h at 21 degrees C-22 degrees C for 10 d without any water and food restrictions. In the second and third groups, sepsis model was formed by cecal ligation and puncture (CLP) method at the end of 10th day, and blood samples were taken at the end of the 10th day. C-reactive protein, Malondialdehyde, Procalcitonin in the blood samples were analyzed by ELISA, and the levels of Total Antioxidant Status and leukocyte were determined by colorimetric method in the subsequent 12 and 24 h. Results: CRP values increased in the second group rats, which were kept continuously under light and had undergone CLP, from 288.8 mg/L to 584.0 mg/L at the end of the 12 h and the end of the 24 h, approximately, two times. In rats, which were kept under 12 h of light, 12 h of darkness, and applied CLP (group 3), these values increased from 416.9 to 619.1; an increase of 1.5 times. When assessed for MDA, it was determined that the differences between Group 2 and Group 3 were more prominent between 0 h and 12 h. While the MDA values in group 2 increased from 16.53 nmol/mL at the 12 h to 17.66 nmol/mL at the 24 h. However, MDA values did not yield statistically significant changes in the third group. Changes in the in PCT values were similar to the MDA values obtained. Increase coefficient of the PCT values between 0 h and 12 h in the second group 2 was 1.26; however, in the third group, it was negligible. Conclusions: An increase in the oxidative stress was observed in the rats that underwent CLP and melatonin deprivation via continuous 24 h light exposure for 10 d. Accordingly, deprivation of light is considered to be effective in sepsis treatment due to the increase in melatonin levels in intensive care unit patients. (C) 2019 Elsevier Inc.

Mohamed; Jamiu, Fadimu Gbemisola; Alsawmahi, Omer N.The objective of the present work was to investigate the influence of locations on bioactive propertiest, phenolic compounds and mineral contents of bee pollens. The oil content of pollen grains changed between 3.50% (Alanya) and 6.85% (Russia-Perm Region). The highest total phenolic content (720 mg/100g) and antioxidant activity values (81.4%) were observed in pollens obtained from the Russia-Perm Region and Alanya districts, respectively. Additionally, the highest carotenoid was found in a pollen sample collected from Karaman (Sanveliler) (98.6 mg/g). The major phenolic compounds were (+)-catechin (66.75-337.39 mg/100g) and quercetin (61.2-1221.7 mg/100g) in all pollen samples. The pollen samples were observed to be a significant source of potassium (3846-6287 mg/kg), phosphorus (2947-5010 mg/kg), calcium (1022-2424 mg/kg) and sulfur (1744-2397 mg/kg). All of the analysis results were significantly affected by supplying locations. The antioxidant activity values of pollens were found partly similar and varied depending on locations. The content of saturated fatty acid (palmitic) was high (20-30%) in the tested pollen samples but did not exceed the content of linoleic acid.Öğe Üniversite öğrencilerinin facebook bağlanma stratejilerinin ve yaşam doyumlarının incelenmesi(2017) Aktürk, Ahmet Oğuz; Emlek, Barış; Çelik, İsmailBu çalışmanın amacı, üniversite öğrencilerinin Facebook bağlanma stratejileri ve yaşam doyumlarını incelemektir.

Such surface deformations - these velocities may vary from a few millimetres to a few metres per year - do the greatest damage to infrastructure facilities and buildings in residential units. Agricultural lands, in which excessive irrigation is performed, and densely populated cities are more likely to suffer from land subsidence. Konya Closed Basin (KCB), where a rapid groundwater withdrawal has been observed during the last 30-40 years, is faced with such a threat. In this study, the possibility of the occurrence of land subsidence, related to groundwater withdrawal for the KCB, is assessed and the geodetic studies conducted up to now, with the intention of identifying land subsidence, are introduced. The vertical displacements of between -12 and -52 mm/year have been detected through GNSS observations collected on the 6-point test network. The land subsidence phenomenon has been developing in the areas where the groundwater is extensively used for irrigation and daily life. The results support the findings derived from the historical leveling records and point out the need of an extended study based on both GNSS and InSAR techniques for spatial and temporal mapping of land subsidence in the KCB.Öğe Physical and Chemical Properties of Some Seed and Kernel Oils(Asian Journal of Chemistry, 2010) Özcan, Mehmet Musa; Endes, Züleyha; Er, FatihNine varieties of the seed and oils (flax, soybean, rice bran, peanut, grape, sesame, almond, sorghum, pistachio) were carried out for a comparative results on their physico-chemical and nutrition value. The oil content of oils ranged from 13.7% (rice bran) to 53.7 % (almond). The protein contents varied between 9.7 % (sorghum) to 22.3 % (peanut). Seeds were evaluated for oil, protein, crude ash and crude fibre. Refraxtive index, relative density, unsaponifiable matter, peroxide value, saponification value and pH values were determined in the seed oils. The main fatty acids identified by gas chromatography were palmitic acid. oleic acid and linoleic acid. The oleic acid content of oils were found high compared with other acids.Öğe Excessive Phosphorus Fertilization Does Not Increase Cadmium Concentrations in Soil or Carrots (Daucus Carota L.) Grown in Konya (Turkey)(Taylor & Francis as, 2010) Öğüt, Mehmet; Er, F.; Brohi, A.The relationships between soil nutrient concentrations, plant nutrient contents, and soil properties were investigated in carrot (Daucus carota L.) fields in Konya-Kasnhan (Turkey). The soils were high in clay content, slightly alkaline, and were moderate to high in CaCO3 content. The soils had sufficient N, Ca, Mg, K, and Fe, but did not have adequate Zn or B for plant growth. The carrots had moderate to high concentrations of Mg, B, Fe, and Zn; however, they had low concentrations of K, Ca, and N. The Cd-content of the soils ranged between 0.06 and 0.91 mg/kg (with a mean of 0.33 mg/kg). The Cd-content of the carrot leaves and organic matter content of the soils were significantly correlated (r= - 0.351, p0.05). Zinc deficiency is a major problem in carrot fields of Konya. Excessive phosphorus fertilization did not seem to result in Cd-pollution of soil or potentially toxic Cd-levels in carrots. The high pH and CaCO3 contents of the calcareous soils lead to stabilization of heavy metals; however, they also result in reduced availability of many plant nutrients. Consequently, soil-management practices, which will increase the availability of plant nutrients in calcareous soils, need to be investigated. Sulfur fertilization could be a way to reduce soil pH to neutrality as a result of oxidation of added sulfur temporarily in calcareous soils.Öğe Evaluation of Geostatistical Mapping Strategies in Monitoring of Spatial Distributions of Iron and Zinc on a Calcareous Barley Field(Wfl Publ, 2010) Susam, Tekin; Karaman, M. Rüştü; Er, Fatih; İşeri, İsmailGeostatistical information on spatial distributions of chemical properties of agricultural soils is important for refining farm managements and precision farming. Site specific monitoring of field soils, that is one of the main steps of precision agriculture, provides more accurate information especially for balancing iron (Fe) and zinc (Zn) levels on the varied soil and plant conditions. In this study, spatial variability of Fe and Zn levels on a calcareous barley field under the barley plants were monitored by performing geostatistical mapping strategies. For this aim, soil samples were systematically taken from the study area at two depths (0-20 and 20-40 cm), on a grid system 10 m x 10 m intervals in the E-W and N-S directions. Descriptive statistics indicated that the coefficient of variation for Fe was low as compared for Zn in both subsoil layer samples. The CV values for Fe and Zn levels were 25% and 33% in topsoil and 23% and 29% in subsoil, respectively. Geostatistical analysis techniques were used in predicting the spatial structure of Fe and Zn levels of soil and plant. The spatial distribution maps were obtained by using Simple Kriging Method (SKM) with spherical semivariogram model for topsoil Fe, SKM with Gaussian semivariogram model for topsoil Zn. The Fe levels of topsoil and Zn levels of subsoil had moderate positional dependence, whereas Zn levels of topsoil and Fe levels of subsoil had weak dependence on the experimental field. The obtained range values were close to each other except for subsoil Fe and changed between 21 m and 15 m. The Fe and Zn levels of barley plants had moderate positional dependence. The results showed that site specific Fe and Zn levels of the field soil could be spatially varied within the small sampling points. The results have revealed that the data values of non-sampled points could be estimated by using SK method and suitable semivariogram model. Evaluation of geostatistical mapping strategies in monitoring of spatial distributions of Fe and Zn levels on a field will improve the decision support for field management practices in a more healthy and moderate way. It will also help to eliminate unequal micronutrient sources of the field soil, which is valuable for balanced crop nutrient consumption.Öğe Comparative Study of Chemical and Biochemical Properties of Different Melon Cultivars: Standard, Hybrid, and Grafted Melons(Amer Chemical Soc, 2010) Kolaylı, Sevgi; Kara, Meryem; Tezcan, Filiz; Erim, F. Bedia; Şahin, Hüseyin; Ulusoy, Esra; Aliyazıcıoğlu, RezzanChemical and biochemical properties of standard, hybrid, and grafted melons cultivated under the same agricultural conditions in adjacent fields in the Cumra region of Turkey were investigated and compared based on pH, Brix, antioxidant activity, total phenolics, ascorbic acid, individual phenolics, sugar, and organic acid values. Seventeen different phenolic constituents were quantified by reverse phase high-performance liquid chromatography (RP-HPLC). The highest phenolic acid variability and content were detected in the standard melon. Sugar and organic acid compositions of melon cultivars were tested by capillary electrophoresis, and significant differences in types and contents of individual sugars and organic acids were determined among the cultivars. Standard Cinikiz Cumra melons had the highest ascorbic acid, total phenolics, and total sugar contents. The fructose/glucose ratio increased three times in grafted melon as compared with standard melon. While sugar alcohol mannitol existed in the standard and hybrid cultivars, this constituent disappeared in the grafted types. Citric acid found in the standard cultivar was not detected in the hybrid and grafted types. Consequently, it was concluded that the nutritional value of melons changed by the application of hybridization, grafting, or standard (open pollinated) production methods. The standard melon was found to have the highest score in terms of taste, because of its highest sweetness and sourness. It was also found preferable because of its high antioxidant activity, total phenolic and ascorbic acid contents.Öğe Determination of Chemical, Physical and Biological Characteristics of Some Pekmez (Molasses) From Turkey(2009) Aliyazıcıoğlu, Rezzan; Kolaylı, Sevgi; Kara, Meryem; Yıldız, Oktay; Sarıkaya, Ali Osman; Cengiz, Sevil; Er, FatihAntioxidant capacity, chemical and physical properties of 6 certificated and 1 uncertificated pekmez (molasses) samples of Turkish varieties were analyzed. All pekmez samples had similar chemical compositions. Total phenolic contents varied from 138 to 243 mg of gallic acid equivalents/100 g samples. The apricot pekmez had the highest phenolic content (243 ± 16), while the carob pekmez exhibited the highest DPPH (0.08 ± 0.01 mg g-1) radical scavenging activity. DPPH radical scavenging activity was also found to be related to concentrations of the samples. Especially, selenium and other minerals content were found slightly higher in grape pekmez than the others. Present results showed that all the certificated and uncertificated pekmez samples had no any risk in public health and besides their high content of sugar. Each pekmez had antioxidant and high amount of polyphenols and minerals.Öğe Weathered Fly Ash Does Not Affect Soil And Biosolid Carbon Mineralization(Taylor & Francis Inc, 2009) Öğüt, Mehmet; Coyne, Mark; Thom, William O.Fly ash and biosolid wastes can be mixed and applied to soil as a means of disposal. A significant decline in soil respiration following waste application indicates restricted activities of functional microbial populations. Weathering decreases salinity and neutralizes alkalinity in fly ash, but there is little information on the effects of unweathered fly ash and biosolid mixtures on soil carbon (C) mineralization. The objective of this study was to determine the effects of a weathered fly ash-limestone scrubber residue (LSR) mixed with an aerobically digested biosolid on soil respiration in a laboratory incubation study. Biosolids significantly increased carbon dioxide (CO(2)) production (p 0.05), but up to 6.75% (w/w) fly ash did not. Mean total C mineralization was 770mg CO(2)-C kg(-1) soil in the control and 3,810mg CO(2)-C kg(-1) soil in the 6.75% (w/w) biosolid treatment. Fly ash with neutral pH and low salinity appears unlikely to affect soil and biosolid C mineralization.Öğe Water Content of Some Medicinal Plants(Int Scientific Conference Sgem, 2009) Tulukçu, Eray; Raziye, KoçakClose parallels between transpiration and water deficit indicate that in diseased plants water loss is largely determined by leaf water content. The rate of water loss (transpiration) depends on evaporation. Therefore anything that affects the rate of evaporation would also affect the rate of water lost. There was no clear relationship between leaf growth rate and leaf water potential or turgor for either species. It decreases with leaf age and is correlated with the rate of dehydration, but it is independent of the tissues water potential.Öğe Dikenli Dağ, Karacadağ, Akdağ (Huğlu-Beyşehir-Konya) ve Çevresinin Florası(2000) Sağlam, Coşkun; Serin, Memduh; Bağcı, Yavuz; Şanda, Murat AydınBu araştırma 1997-1999 yılları arasında Dikenlidağ, Karacadağ, Akdağ (Huğlu-Konya) ve çevresinde gerçekleştirilmiştir.
