Continuous changes in producer and consumer demands also create a competitive environment in pepper breeding. Green pepper cultivation is generally carried out in greenhouse cultivation, and its cultivation has become widespread in open field conditions. In the study, 8 F1 (G12, G11, K42, B25, L9, Z22, G14 and L10) pepper varieties with superior characteristics were used as plant material. Some plant, leaf and fruit characteristics as well as yield and quality parameters were examined. As a result of the principal components analysis (PCA) made using theese measurements and observations, the study was explained variations in 6 components at a high rate of 97.94%. G11 and G12 cultivar candidates are located in the positive region of both components in the Score plot graph drawn from the first two components which means that these two candidates showed the highest performance among those evaluated ones. These cultivar candidates showed superior characteristics in terms of yield, fruit weight, fruit width, TTS, pH, L and b parameters. It is thought that these cultivar candidates can be grown in open land conditions having semi-arid climate.Öğe Effects of Different Arbuscular Mycorrhizal Fungi (AMF) Species on Some Bean (Phaseolus Vulgaris L.) Cultivars Grown in Salty Conditions(Academic Journals, 2010) Çiftçi, Vahdettin; Türkmen, Önder; Erdinç, Çeknas; Şensoy, SuatThis study was carried out to determine the effects of three different Arbuscular Mycorrhizal Fungi (AMF) species (Glomus mosseae, Glomus intraradices and Glomus fasciculatum) on the growth and nutrient contents of four bean cultivars (Onceler, Seker, Terzibaba and Sehirali) grown under salt stress. The constant amount of NaCl (50 ppm) was added the autoclaved growth medium containing 1:1:1: ratios of soil, sand, and manure. The five gram (25 spores g(-1)) of inoculum was placed in the seedling growth medium before the seeds were sown. At the end of the study, some nutrients such as N, P, K, Ca, Mg, Fe, Cu, Mn, and Zn and plant growth parameters such as shoot height, stem diameter, root length, leaf number, leaf area, and dry and fresh weights of shoots and roots were investigated. Moreover, the plant colonization rates of AMF species were determined. The AMF species had positive effects on the plant growth and nutrient intake. Among the bean cultivars, Onceler and Terzibaba, and among the AMF species, G. mosseae had the best results for plant growth.Öğe Effects of Humic Acid Doses and Aplication Times on the Plant Growth, Nutrient and Heavy Metal Contents of Lettuce Grown on Sewage Sludge-Applied Soils(Parlar Scientific Publications (P S P), 2006) Tüfenkçi, Şefik; Türkmen, Önder; Sönmez, Ferit; Erdinç, Çeknas; Şensoy, SuatEffects of increasing doses of humic acid (HA), applied in different periods, on the plant growth, nutrient and heavy metal contents of lettuce grown on sewage sludge-applied soils were investigated. A constant dose of 20% sewage sludge (SS) was added to experimental soil placed in pots. Various doses of HA (0, 500, 1000, and 2000 mg kg(-1)) were applied to the pots for different time periods (0, 30, 60, and 90 days before seedling transplantation). Increasing doses of HA significantly affected the plant and neck diameter, the plant height, the number of leaves, but not the plant weight. Application times of HA significantly influenced all plant growth parameters mentioned above. Moreover, there were significant effects of the interaction of HA dose and application time on the diameters, heights, and weights of lettuce plants. There were significant effects of increasing doses of HA on the N, P, K, Ca, Mg, Fe, Zn, and Cd contents of lettuce plants. Their Cd, Cr, and Co contents decreased with increasing HA doses. Also, significant differences in N, P, K; Mn, Cd, and Ni contents could be observed for various application times of HA. Moreover, the Mn content of lettuce was affected by the time and dose interaction. As a result, the application of HA had positive impacts on the plant growth and nutrient contents of lettuce, and increasing doses of HA reduced the heavy metal contents, such as Cd, Cr, and Co, in lettuce plants. The early application of HA for lettuce, with a short growing period, had more beneficial effects for the plant growth and nutrient content.Öğe Effects of Potassium and Humic Acid on Emergence, Growth and Nutrient Contents of Okra (Abelmoschus Esculentus L.) Seedling Under Saline Soil Conditions(Academic Journals, 2010) Paksoy, Mustafa; Türkmen, Önder; Dursun, AtillaThe effects of potassium and humic acid (HA) on emergence, growth and nutrient contents of okra (Abelmoschus esculentus L cv. Sultani) seedlings in saline soil conditions were evaluated. Different levels of humic acid (0, 500, 1000 and 1500 mg kg(-1)) and potassium (0, 75, 150 and 300 mg kg(-1)) were applied on growing media treated with 50 mg NaCl kg(-1) before seed sowing. The experiment was designed as randomized completely factorial block and each parcel had ten pots without drainage. Two okra seeds were sown in each pot having 300 cc volumes of growth media. The seedlings were thinned to one after emergence. The seedlings were irrigated with distilled water. Seed emergence, root and shoot size, leaf number, shoot and root dry weights of the plant seedlings were determined. Macro and micro nutrient (N, P, K, Ca, Mg, S, Cu, Fe, Mn and Zn) contents of seedlings were also determined. All data were subjected to a one-way analysis of variance and separated by Duncan's multiple range test which was performed using the Costat statistical software. There were statistical differences in terms of effects of potassium and HA on the okra seedling performances. The effects of K, Ca, Na, Cu, Fe, Mn, Zn and HA applications on plant mineral (N, P, K, Ca, Cu, Fe, and Mn) contents were significant at p < 0.005.Öğe Evaluation of fatty acid composition, oil yield and total phenol content of various pumpkin seed genotypes(INNOVHUB SSI-AREA SSOG, 2015) Türkmen, Önder; Uslu, Nurhan; Paksoy, M.; Seymen, Musa; Fidan, S.; Özcan, Mehmet MusaIn this research, crude oil and total phenol contents were determined in 29 unit edible pumpkin seeds genotypes. Fatty acid compositions of these pumpkin seed oils were also investigated. According to the results, oil contents of pumpkin seeds ranged from 22.74% to 39.24%. The major unsaturated fatty acids of the samples were oleic acid (26.14% - 39.97%) and linoleic acid (38.52% - 54.31%); saturated fatty acids were stearic acid (5.01% - 7.87%) and palmitic acid (10.24% - 15.10%). Other fatty acids such as linolenic, myristic, behenic, arachidic acid, etc. were found in small quantities. Total phenol contents of genotypes varied from 0.376 to 0.716 mg GAE/100 g. Results indicated that pumpkin seeds could be used as a new oil source.Öğe Genetic variation within the purple carrot population grown in Ereğli District in Turkey(2016) İpek, Ahmet; Türkmen, Önder; Fidan, Sali; İpek, Meryem; Karcı, HarunAlthough the majority of carrots grown in Turkey and around the world are orange, the production of anthocyanin-containing purple carrots has recently increased in Turkey due to the extraction of anthocyanin from these carrots for use as a natural food colorant. Purple carrot production for this purpose is concentrated in Ereğli District in Konya Province, and open-pollinated local purple carrot cultivars or landraces have been used for this production. Genetic variation within the local purple carrot populations in this region is of interest to plant breeders worldwide for the development of new purple carrot cultivars. Therefore, in this study, genetic variation within the purple carrot population grown in Ereğli District was assessed using SSR markers. Purple carrot samples were collected by visiting 14 purple carrot growing fields in this region. A total of 20 SSR markers were used. Two SSR markers were monomorphic and the remaining 18 SSR markers amplified 106 SSR alleles. The number of polymorphic alleles per SSR marker ranged from 1 to 14. The polymorphism information content varied from 0.29 to 0.85, and the expected heterozygosity ranged from 0.32 to 0.87. STRUCTURE analysis indicated the presence of two distinct populations within the purple carrot genotypes used in carrot production in Ereğli District. The genetic similarity of the genotypes ranged from 0.20 to 0.70. These results indicate that the genetic variation within these carrot populations in Ereğli District is high, and the purple carrot populations in this region are valuable genetic resources for the development of new purple carrot cultivars.Öğe Kavunda ebeveyn hat ile melezlerinin bazı tohum ve tohum çıkışı özelliklerinin belirlenmesi(2017) Tur, Ayşegül; Seymen, Musa; Türkmen, ÖnderBu çalışma, 2015-2016 yıllarında yürütülmüş ve bitkisel materyal olarak, 13 genotip (SÇ-1: Sel-1-1.

Mesut; Türkmen, Önder; Turan, Metin; Tuncer, BurcuHumic acid is a commercial product that contains many elements which improve the soil fertility and increase the availability of nutrient elements. It consequently affects plant growth and yield and ameliorates the deleterious effects of salt stress. The objective of the study was to determine the effect of humic acids and phosphorus on growth and nutrient content of pepper seedlings (cv. Demre) grown under moderate salt stress in growth chamber conditions. Applications of different levels of phosphorus [0 (P(0)), 50 (P(1)), 100 (P(2)) and 150 (P(3)) mg kg(-1)] and humic acid [0 (HA(0)), 750 (HA(1)) and 1500 (HA(2)) mg kg(-1)] to growing media containing moderate salt dose (8 mM NaCl treatment) were studied. The study was replicated four times with 20 plants in each replicate. Humic acid (HA) and phosphorus applications increased the growth and growth parameter of plants. In company, effects of HA and P application was more effective on growth and growth parameter than each separate effect. The optimum total yield was obtained from 69 mg kg(-1) P application with HA2 doses according to regression analysis. Humic acid application significantly increased N, P, K, Ca, Mg, S, Mn and Cu contents of shoot of pepper seedling. Also, N, P, K, Ca, S, Fe, Mn, Zn and Cu contents of root were increased with humic acid application. Na contents of both shoot and root of pepper decreased with increased humic acid doses. It can be concluded that high humic acid doses has positive effects on salt tolerance based on the plant growth parameters and nutrient contents. The present study suggests that HA treatments can ameliorate the deleterious effects of salt stress on pepper plants and HA could offer an economical and simple application to reduce problems of pepper production in moderately saline soil.Öğe Toxic effects of excess Cu2+and Zn2+on growth and some antioxidant enzymes of tomato (solanum lycopersicum L.)(2010) Bozkurt, Mehmet Ali; Şensoy, Suat; Çelik, İsmail; Türkmen, Önder; Bitiktaş, AyşegülThe toxic effects of excess Cu2+ and Zn2+ doses on growth of tomato seedlings were studied in a pot experiment with the measurement of fresh and dry biomass of the plants. The toxic effects of both elements were evaluated by measuring copper and zinc accumulations, glutathione S transferase (GST) and superoxide dismutase (SOD) activities in tomato plants. The doses were 0, 150, 300, 450, and 600 mg kg-1 of copper as well as 0, 250, 500, 750 and 1000 mg kg-1 of zinc, and two separate pot experiments were conducted for these metals. The experimental results demonstrated that the excess Cu2+ and Zn2+ applications inhibited the growth of tomato seedlings and diminished their biomasses. The applications increased copper and zinc accumulations in the shoots and roots in comparison to control treatments. The accumulations were markedly higher in the roots than those in the shoots. The excessive Cu2+ amounts caused significant decreases in the GST and SOD activities of the roots. However, the SOD activities in the shoots significantly increased with excessive Cu2+ doses. The excessive Zn2+ applications significantly affected the GST activities in the shoots and the SOD activities in the roots. Both enzyme activities in the roots decreased with excessive Cu2+ and Zn2+ applications. This study shows that GST and SOD activities in tomatoes may be used as sensitive indicators of copper and zinc toxicity. © by PSP.Öğe Türkiyenin bazı fasulye genotiplerinin çeşitli bitkisel özelliklerinin belirlenmesi(2013) Erdinç, Çeknas; Türkmen, Önder; Şensoy, SuatBu çalışmada Türkiyenin değişik bölgelerinden elde edilen 125 adet fasulye genotipinin çeşitli bitkisel özellikleri değerlendirilerek genotipler arasındaki çeşitliliğin saptanması amaçlanmıştır.

Melon seedlings were evaluated with two different scales based on disease incidence and vascular discoloration. The disease frequency on the 50 melon genotypes varied differently. It was found that although there were several resistant melon genotypes to F.o.m. race 0, most of the melon genotypes were found susceptible to F.o.m. race 1,2.Öğe Yerel kavun (Cucumis melo L.) genotiplerinin bazı morfolojik özellikleri(2017) Dal, Yeşim; Kayak, Necibe; Kal, Ünal; Seymen, Musa; Türkmen, ÖnderBu çalışma, Türkiye'nin farklı bölgelerinden toplanan ve S4 kademesine kadar kendilemeleri yapılan Cucumis melo L. aksesyonlarının morfolojik çeşitliliğinin belirlenmesi amacıyla yapılmıştır. Çalışmada ortalama bitki boyu, ana gövde çapı, ana gövde de boğum sayısı, meyve ağırlığı, meyvede mühür büyüklüğü, meyve eti kalınlığı, meyvede kabuk kalınlığı, meyvede SÇKM ve pH sırası ile; 77.31 cm, 4.58 mm, 6.35 adet/bitki, 673.29 g, 8.06 mm, 12.66 mm, 6.68 mm, %6.98, 5.85 olarak bulunmuştur. Genotiplerin %90.9'unda monoik, %9.01'unda andromonoik çiçek yapısına sahiptir. Meyve şekillerinden %3.75'i meşe palamudu, %39.6'sı oval, %5.6'sı priform, %49'u küresel, %1.8'i basık, ve baskın meyve kabuk renkleri; %9.4'ü soluk yeşil, %45.2'i yeşil, %41.5'i kahverengi, %1.8'i açık sarı, %1.8'i siyahımsı yeşil tespit edilmiştir. Genotiplerde görülen kabuktaki ikincil renk dağılımı %18.8'i yok, %28.30'u benekli, %30.18'i lekeli, %13.20'si bantlı ve %9.43'ü çizgili olup kabuk desen rengi; %92.4'ünde yeşil, %7.5'inde sarı olarak bulunurken olgunluk öncesi meyve kabuk zemin rengi % 3.7'sinde sarı, %5.6'sında gri yeşil, %90.5'inde yeşil olarak bulunmuştur. Meyvede ağlanma durumu %77.3'ünde az, %1.8'inde orta ve %3.7'sinde çok olarak tespit edilmiştir. Genotiplerin meyve sapı uzunluğu %43.3'ü kısa, %5.6'sı uzun, %50.9'u orta olarak tespit edilirken meyve sapı kalınlığının %98.1'i orta ve %1.8'i ince olarak bulunmuştur. Kavun genotiplerinin meyve taban şekilleri açısından %66'sı yuvarlak, %16.9'u düz ve %17.1'i sivri uçlu bulunmuş olup meyve ucu şekli %41.5'inde yuvarlak, %32'sinde yassı, %26.4'ünde sivri olarak bulunurken meyve eti
