Öğe Agronomic and quality characteristics of some virginia type peanut genotypes (Arachis hypogaea I. subs, hypogaea van hypogaea) and effects of these characters on yield formation as an alternate crop in hatay district(TUBITAK, 2000) Çalişkan, Mehmet Emin; Mert, Mehmet; Işler, Necmi; Calişkan, SevgiAgronomic and quality characteristics of 16 Virginia type groundnut cvs. and, direct and indirect effects of these characters on yield formation as an alternate crop were investigated in Hatay district in 1995 and 1996. The genotypes differed significantly in respect to all investigated characters, and it was concluded that the peanut could be an important alternate crop for Hatay district based on the results of pod yield, which ranged between 211.9 and 311.3 kg/da. Correlation and path coefficient analysis also revealed that the number of pods per plant, pod yield per plant and kernel/pod ratio correlated significantly with pod yield per decare, and pod yield per plant and kernel/pod ratio characteristics in particular had the highest positive direct effects on pod yield per decare under regional conditions.Öğe Ağır metal (Ni, Cd ve Cu) uygulamalarının Andız Otu, Fener Otu ve Sığırkuyruğu bitkilerinin büyüme ve gelişmesi üzerine etkisi(2017) Eren, Abdullah; Mert, MehmetBu 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.Öğe Combining non-destructive devices and multivariate analysis as a tool to quantify the fatty acid profiles of linseed genotypes(Elsevier B.V., 2025) Arslan, Aysel; Aygun, Yusuf Ziya; Turkmen, Musa; Celiktas, Nafiz; Mert, MehmetLinseed (Linum usitatissimum L.) and linseed oil, with a fatty acid profile rich in both macro and micro elements, are recognized as functional foods due to their valuable positive effects on health. Fatty acids composition (FAC) is a key indicator in assessing the quality of linseeds. The FAC of linseed is typically determined using chromatographic methods, yielding highly accurate results. However, chromatographic methods entail drawbacks such as requiring pre-chemical processes, generating chemical waste, and being both expensive and time-consuming, similar to chemical analyses. This study focused on the feasibility of colorimeter and FT-NIRS data to determine the FAC (%), protein (%) and neutral detergent fiber (NDF %) in linseed samples. By employing the PLSR analysis based on FT-NIRS, it was determined that the ratios of stearic (R2val = 0.74, RMSEP = 0.09 %), oleic (R2val = 0.75, RMSEP = 0.26 %), linoleic (R2val = 0.85, RMSEP = 0.58 %), linolenic (R2val = 0.71, RMSEP = 1.07 %), 8,11,14 eicosatrienoic (R2val = 0.77, RMSEP = 0.02 %), margaric (R2val = 0.71, RMSEP = 0.01 %), myristic (R2val = 0.75, RMSEP = 0.02 %), and behenic (R2val = 0.74, RMSEP = 1.12 %) in linseed could be successfully predicted. Furthermore, results demonstrated that the protein (R2val = 0.87, RMSEP = 0.9 %) and NDF (R2val = 0.90, RMSEP = 0.6 %) content in linseeds can be successfully predicted. PLSR has demonstrated that FT-NIRS has relatively higher predictive capability compared to color models. © 2024 Elsevier B.V.Öğe Determiantion of superior parents and hybrid combinations in respect to lint yield and yield components in cotton (Gossypium hirsutum L.)(2003) Mert, Mehmet; Gencer, Oktay; Akışcan, Yaşar; Boyacı, Kenan2000 yılında, Gossypium hirsutum L. türünden 5 çeşit (Sure Grow 125, Sure Grow 404, Sure Grow 501, Sure Grow 1001 and Çukurova 1518) ana, 7 hat ise (PAUM 400, PAUM 401, PAUM 402, PAUM 403, PAUM 404, PAUM 405 ve PAUM 406) baba olacak şekilde, line x tester melezleme yöntemine göre Çukurova Üniversitesi, Pamuk Araştırma ve Uygulama Merkezinde birbirleriyle melezlenmiştir. Elde edilen 35 F, melezi ve 12 anaç, 2001 yılında tesadüf blokları deneme desenine göre üç tekerrürlü olarak ekilmiş ve lif verimi ve verim öğeleri bakımından değerlendirilmiştir. Elde edilen verilere, line x tester analizi uygulanmıştır. Çalışmada anaçların genel, melezlerin özel uyum yeteneklerinin belirlenmesi, ve böylece erken generasyonlarda lif verimi ve verim öğeleri yönünden üstün anaçların ve melez kombinasyonların seçilmesi amaçlanmıştır. Sonuç olarak, ebeveyn ve hibridlerin genel ve özel uyum yetenekleri, lif verimi ve verim öğeleri bakımından önemli farklılıklar oluşturmuştur. Ebeveynler arasında, PAUM 403 koza sayısı; Çukurova 1518, PAUM 400, PAUM 403, PAUM 405 ve PAUM 406 lif verimi; Sure Grow 501, Çukurova 1518, PAUM 401 ve PAUM 405 çırçır randımanı; Sure Grow 125, PAUM 400 ve PAUM 403 100 tohum ağırlığı; Çukurova 1518, PAUM 400, PAUM 405 ve PAUM 406 koza kutlu pamuk ağırlığı yönünden en yüksek genel uyum yeteneğine sahip olmuşlardır. Sure Grow 501 x PAUM 400 koza sayısı yönünden özel kombinasyon kabiliyeti önemli tek melez kombinasyon olarak tespit edilmiştir. Ayrıca, bu melez kombinasyon en yüksek lif verimine de sahiptir. Elde edilen bu sonuç, ileriki generasyonlarda amaca yönelik bitkilerin, bu melez kombinasyondan seçilme şansının daha yüksek olduğunu göstermektedir.Öğe Determination of superior parents and hybrid combinations in respect to lint yield and yield components in cotton (Gossypium hirsutum L.)(TUBITAK, 2003) Mert, Mehmet; Gençer, Oktay; Akişcan, Yaşar; Boyaci, KenanThe purpose of this study was to determine estimates of the general combining ability of parents and the specific combining ability of hybrids needed to develop high yielding cotton cultivars. Five cotton lines (Sure Grow 125, Sure Grow 404, Sure Grow 501, Sure Grow 1001 and Çukurova 1518) and 7 testers (PAUM 400, PAUM 401, PAUM 402, PAUM 403, PAUM 404, PAUM 405 and PALM 406) were crossed in a line x tester mating system at Çukurova University. Cotton Research and Application Center, Adana, Turkey, in 2000. Twelve genotypes and 35 F1 hybrids were sown in a randomized complete block design with 3 replications at the same center in 2001. The general combining ability variance of parents and the specific combining ability variance of hybrids in respect to lint yield and yield components were estimated via line × tester analysis. Line × tester analysis revealed significant general and specific combining ability effects for lint yield, 100-seed weight, seed cotton weight per boll, lint percentage and boll number per plant. The following lines had higher general combining abilities than the others: PAUM 403 for boll number per plant: Çukurova 1518, PAUM 400, PAUM 403, PAUM 405 and PAUM 406 for lint yield: Sure Grow 501, Çukurova 1518, PAUM 401 and PAUM 405 for lint percentage; Sure Grow 125, PAUM 400, PAUM 403 for 100-seed weight; and Çukurova 1518. PAUM 400, PALM 405 and PAUM 406 for seed cotton weight per boll. Only Sure Grow 501 × PAUM 400 F1 showed significant specific combining ability effects for bolls/plant. It yielded more total lint than the others. This F1 achieved its high yield by producing many boll numbers per plant, while the others produced fewer.Öğe Effect of different irrigation water level on cotton yield and yield components(Academic Journals, 2009) Onder, Derya; Akiscan, Yasar; Onder, Sermet; Mert, MehmetEffects of different water level on yield and yield components of the drip irrigated cotton were evaluated in Amik Plain in the East Mediterranean Region of Turkey. Four levels of irrigation water were tested in 2003 and 2004. Treatments were 25 (I-25), 50 (I-50), 75% (I-75) of the full irrigation treatment (I-100) which received 100% class-A pan evaporation. Numbers of irrigation events were 5 and 8 in 2003 and 2004, respectively. Under I-25, I-50 and I-75 treatment conditions, evapotranspiration, total cotton seed yield, boll weight, lint percentage, number of sympodial branches and leaf area index decreased while some boll parameters such as boll weights and opened boll numbers increased. Increase of boll number per plant under water stress condition showed that cotton had high ability for adapting water stress conditions. The highest yield was obtained in the I-100 treatment. A second degree polynomial relation could adequately describe the cotton seed yield response to the irrigation water amount. The highest irrigation water use efficiency (IWUE) was obtained with the I-50 treatment.Öğe The effect of phosphorus doses on cotton growth under full and deficit irrigation conditions(2021) Aygün, Yusuf Ziya; Mert, MehmetWater shortages and harmful effects of excessive fertilizer use are present in cotton production areas. This \rstudy was carried out in three replications in greenhouse conditions according to split plots in randomized parcels to \rexamine some growth parameters (plant height, number of leaf, amount of chlorophyll, fresh weight and dry weight) of \rdifferent phosphorus doses in cotton under full and restricted irrigation conditions. Flash cultivar of Gossypium \rhirsutum L. species was used as plant material. Phosphorus dose of 16, 24, 32 and 40 mg kg-1 was applied to the plants \runder 100%, 66% and 33% irrigation conditions. As a result, irrigation levels had a statistically significant effect on all \rparameters, whereas phosphorus doses had a statistically significant effect on all parameters except amount of \rchlorophyll. In terms of irrigation, it was determined that 33% water shortage did not cause significant decreases in \rplant height, number of leaves, chlorophyll amount, dry weight. In addition, it has been determined that irrigation levels \rare effective in phosphorus uptake and, water shortage conditions decrease the fresh and dry weights of cotton after P24 \rphosphorus level, and full irrigation conditions tend to increase these properties, albeit slightlyÖğe The effects of mepiquat chloride (PIX) on yield,yield components and fiber characteristics of cotton(1998) Mert, Mehmet; Çalışkan, Mehmet EminThe effects of different doses of the mepiquat chloride (MC) applied at different growth stages tand different does on the yield, yield components and fiber characteristics of cotton (G. hirsutum L.) were investigated under Amik Plain conditions under 1996 and 1997. MC treatments reduced plant height and improved earliness of cotton crop in both years while its effect on seed cotton yield showed inconsistency between years. It was also determined that multiple applications of MC had more positive effects on seed cotton yield and earliness. MC also affected significantly the seed cotton weight per boll in both years and the ginning outturn in 1996, MC did not create significant differences on the other morphological and fiber characteristics in both years.Öğe Effects of soil conditioners and nitrogen applications on cotton (Gossypium hirsutum L.) yield and fiber technological properties(Ersin Yücel, 2020) Aygün, Yusuf Ziya; Mert, MehmetThis study aimed to reduce the use of chemical fertilizers and to reach sufficient yields and fiber quality withnatural soil conditioners in 2019 growing season in Amik Plain, Hatay, Turkey. The experiment was carried out usingrandomized complete block design with split-plot arrangement in 3 replications. The treatments consisted of two soilconditioners (leonardite and zeolite, 1000 and 2000 kg ha-1) allocated in the main plots, and 5 nitrogen doses (0, 50,100, 150 and 200 kg ha-1) applied in the subplots. Soil conditioners and applied nitrogen doses had no significant effecton plant height, number of monopodia, number of sympodia, number of boll, seed cotton weight per boll, fiber fineness,fiber strength and 100 seed weight. However, ginning percentage was the only parameters that significantly affectedfrom nitrogen doses. The soil conditioner and nitrogen interaction was significant for yield and fiber length. Furtherstudies are needed to determine the effects of soil conditioner and nitrogen application on yield and fiber propertiesunder different soil and climate conditions.Öğe Endüstriyel kenevir (Cannabis sativa L.) tohumlarının çimlenme süresince yağ ve yağ asidi oranlarının değişimleri(2023) Aygün, Yusuf Ziya; Mert, MehmetBu çalışma endüstriyel kenevir tohumlarının çimlenmesi boyunca yağ oranı ve yağ asidi içeriklerinin değişimini incelemeyi amaçlamıştır. Kontrollü koşullarda çimlenen endüstriyel kenevir (Cannabis sativa L. çeşit Vezir-55) tohumlarından 0 (kontrol), 24, 48, 72 ve 96. saatlerde alınan örneklerden yağ elde edilerek yağ oranı ve yağ asidi içerikleri tayin edilmiştir. Behenik, lignoserik, linoleik, palmitik, gamma-linolenik asit oranları ve çoklu doymamış yağ oranları üzerine çimlenme saatlerinin etkisi istatistiksel olarak önemli bulunmuştur. Bu parametreler için en düşük ve yüksek değerler sırasıyla %0.22-0.35, %0.40-0.70, %47.33-49.11, %9.96-9.01, %1.29-1.61 ve %69.96-71.69 olarak tespit edilmiştir. Tohumdaki yağ oranı, araşidik, eykosapentaenoik, laurik, alfa-linolenik, margarik, miristik, oleik, palmitoleik, risinoleik, stearik asit oranları ve doymuş ve tekli doymamış yağ asitleri oranları ise çimlenme saatlerinden etkilenmemiştir. Çalışmada elde edilen değerlere göre çimlenme sırasında yağ asitleri oranlarında değişimler olduğu önceki çalışmalarla benzerlik gösterirken yağ asitlerinin tohum tarafından seçici kullanımı ve sentezlenmesinin bitki türüne göre farklılık gösterdiği sonucuna varılmıştır.Öğe Evaluation of some safflower (Carthamus tinctorius L.) cultivars for morpho-agronomic characters under Hatay ecological conditions(1998) Çalışkan, Mehmet Emin; Mert, Ahmet; Mert, Mehmet; İşler, NecmiSome morphological and agronomical characteristics of seven safflower cvs. (Oleicleed, Yerli CK, 308, 5-154, Yenice, Dincer and 416-5) were investigated at autumn sowing under Hatay ecological conditions in 1995-96 and 1996-97 growing seasons. The safflower cultivars differed significantly for all characters studied; but, especially the cultivars Dincer and 5-154 resulted in high seed and oil yield. Based on the results of two years, it was concluded that safflower crop had a growing potential in non-irrigated areas of Hatay region with autumn sowing.Öğe Genotype X environment interaction and stability analysis of some fiber properties in cotton (Gossypium hirsutum L.)(2001) Mert, Mehmet; Çalışkan, Mehmet Emin; Günel, ErolThe performances of fourteen cotton (Gossypium hirsutum L.) cultivars in respect to some fiber properties were evaluated under the conditions of thirteen environments (Izmir, Manisa, Denizli, Aydın in 1997 and 1998; Hatay in 1997, 1998 and 1999; Şanlıurfa and Adana in 1998) in Turkey. The variance components for genotypes, environments and genotype x environment interaction were found to be significant for all the fiber properties investigated, although variance for interaction effect was smaller as compared to genotype's and environment's. The data were analyzed for stability parameters, to identify the genotypes showing stable performance in respect fiber properties in a wide range of environmental conditions. None öf the cultivars tested could combine both high adaptability and stability in respect to three fiber properties under evaluation. The genotypes Sure Grow 125, Deltapine 5409 and Sayar 314 could corporate both high adaptability and stability in respect to fiber length and fineness, while the genotypes Sure Grow 404 and Sure Grow 1001 showed high adaptability to all environments in respect to fiber strength.Öğe Hatay yöresinde II. ürün olarak yetiştirilen Virginia tipi bazı yerfıstığı (Arachis hypogaea L. subps hypogaea var. hypogaea) genotiplerinin önemli tarımsal ve kalite özellikleri ile bu özelliklerin verim oluşumuna etkileri(2000) Çalışkan, Mehmet Emin; Mert, Mehmet; İşler, Necmi; Çalışkan, SevgiAgronomic and quality characteristics of 16 Virginia type groundnut cvs. and, direct and indirect effects of these characters on yield formation as an alternate crop were investigated in Hatay district in 1995 and 1996. The genotypes differed significantly in respect to all investigated characters, and it was concluded that the peanut could be an important alternate crop for Hatay district based on the results of pod yield, which ranged between 211.9 and 311.3 kg/da. Correlation and path coefficient analysis also revealed that the number of pods per plant, pod yield per plant and kernel/pod ratio correlated significantly with pod yield per decare, and pod yield per plant and kernel/pod ratio characteristics in particular had the highest positive direct effects on pod yield per decare under regional conditions.Öğe Inheritance of yiled and yield components in cotton (Gossypium hirsutum L.)(2003) Mert, Mehmet; Gencer, Oktay; Akışcan, Yaşar; Boyacı, KenanThis study was conducted to investigate the inheritance of yield and yield components in cotton. Crosses between Sure Grow 125 and PAUM 401 (Gossypium hirsiitum L.) in 2000, and backcrosses between F] and parents (Sure Grow 125 and PAUM 401) in 2001 were made under field conditions at Çukurova University, Cotton Research and Application Center, Adana. Four generations ($F_1, F_2, B_1, and B_2$, in which $B_1$ represents a backcross between $F_1$ and Sure Grow 125 and $B_2$ represents a backcross between F, and PAUM 401), and parents were tested at the same center in 2002. Generation mean analysis was used to estimate the type of gene action determining yield and yield components. It was concluded that additive, dominance and. epistatic gene effects were responsible for the inheritance of lint yield, boll number per plant and lint percentage whereas only dominance effects were involved in inheritance of seed cotton weight per boll and 100 seed weight.Öğe Physico-chemical characteristic and fatty acids compositions of cottonseed oils(2017) Bozdoğan Konuşkan, Dilşat; Yılmaztekin, Murat; Mert, Mehmet; Gençer, Oktayommon oil being used today besides sunflower oil. As the most important vegetable oil source in Turkey, sunflower is first ranked with 1.38 million tons, followed by cottonseed with 1.28 million tons, soybean 180,000 ton, peanut 141,000 tons and rapeseed 101,000 tons (Kolsarıcı et al 2015).Cottonseed oil is usually used in vegetable oil mixtures (Metin et al 2003), cooking and salad oil, in the preparation of margarine, shortening, mayonnaise and sauces, also to less extend in canned fish and smoked meat (Gtoplam karotenoid içerikleri 119-140 mg kg-1, toplam tokoferol içerikleri 887-920 mg kg-1 aralığında değişmiştir. Linoleik asit, palmitik asit, oleik asit ve stearik asit oranlarının, sırasıyla % 52.0-55.82; % 24.85-25.63, % 14.06-17.0 ve % 3.01-3.13 aralığında değiştiği saptanmıştır. PAUM 15 genotipinin en yüksek yağ verimi ve yağ kalitesine sahip olmasından dolayı diğer genotiplere kıyasla yemeklik yağ olarak tüketime daha uygun olabileceği belirlenmiştir.Öğe YIELD AND FIBER QUALITY CHARACTERISTICS OF SOME COTTON (Gossypium hirsutum L.) CULTIVARS GROWN IN THE SOUTHEASTERN ANATOLIAN CONDITIONS(Soc Field Crop Sci, 2022) Aslan, Ramazan; Aygun, Yusuf Ziya; Mert, MehmetThe aim of this study was to determine cotton cultivars for high yield and fiber technological characters in Southeastern Anatolian ecological conditions. For this purpose, the study was carried out with 11 cotton (Gossypium hirsutum L.) cultivars in 2019 and 2020. Field experiment was designed based on randomized complete block design with four replications. The results of combined analysis indicated that there were significant differences between cultivars in terms of yield and quality parameters except for the number of monopodia, fiber strength and fiber fineness. It was determined that cv. Edessa and cv. PG 2018 were superior to other cultivars for seed cotton yield, in respectively 4006.25 kg ha-1, 3971.42 kg ha-1. While these cultivars had higher fiber yield than all others, they were the least affected by the year difference. Cv. PG 2018 also had the highest plant height and ginning turnout. It was concluded that cv. Edessa and cv. PG 2018 are more suitable for cultivation in Batman ecological conditions.
