(Springer, 2018) Erdinc, Ceknas; Ekincialp, Aytekin; Gundogdu, Muttalip; Eser, Fuat; Sensoy, Suat
This study investigated the organic acid and phenolic compound levels, total phenolic (TP) and antioxidant capacity (TEAC) of three miniature tomato cultivars grown on a farmer's field with three different fertilizer applications. Analysis of phenolic compound (protocatechuic, vanillic, gallic, chlorogenic, caffeic, syringic, p-coumaric and ferulic acid, rutin, quercetin, catechin and phloridzine) organic acid (citric, tartaric, malic, succinic and fumaric acid), TP and TEAC levels in fruit samples showed statistically significant (p < 0.05) differences between tomato cultivars and fertilizer applications. Rutin and chlorogenic acid were the predominant phenolic compounds found in all three cultivars. The highest rutin value (50.48 mg kg(-1) FW) was found in the Black Zebra fertilized with DAP plus organic and biochemical fertilizers and the lowest (20.52 mg kg(-1) FW) in the Black Zebra fertilized with DAP only. The highest chlorogenic acid value (63.31 mg kg(-1) FW) was found in the sweet pea currant fertilized with DAP only and the lowest (21.06 mg kg(-1) FW) in the Black Zebra fertilized with DAP plus chemical fertilizer. Citric acid content was the dominant organic acid in all three cultivars, with the highest citric acid value (6439.50 mg kg(-1) FW) found in the Sweet Pea Currant cherry tomato fertilized with DAP plus organic and biochemical fertilizers and the lowest (2435.20 mg kg(-1) FW) in the Window Box Yellow fertilized with DAP plus chemical fertilizer. Total phenolic and antioxidant levels in the window box yellow were significantly lower as compared to the Black Zebra and sweet pea currant varieties for all three fertilizer applications.
Bioactive Compounds in Different Melon (Cucumis Melo L.) Genotypes and One Cultivar Grown Under Deficit Irrigation and Salt Stress
(Univ Life Sciences Lublin, 2024) Ekincialp, Aytekin
Drought and salinity are the most important abiotic factors limiting agricultural production. One of the effective ways to avoid their negative effects on plants is to determine the genotypes that will show resistance to these stress conditions. In addition, the gradual decrease in water resources in the world makes minimum water consumption important in agriculture. For this purpose, three different irrigation levels (I100: control - 100% full irrigation, i.e. 0% deficit irrigation, I50: 50% deficit irrigation, I25: 25% deficit irrigation) were applied within the framework of water constraint, and NaCl was applied at the doses of S0: 0 mM (control), S50: 50 mM and S75: 75 mM to create salt stress, and the experimental plots were designed according to the random plot experimental design with three replications and four plants in each replication. In the genotype x salinity interaction, compounds other than fumaric acid from organic acids formed significant interactions with genotypes YYU-4 and YYU-10. Among phenolic compounds, parameters other than total phenolic and antioxidant content formed significant interactions mainly with cv. Ananas. In the genotype x irrigation interaction, among organic acids, oxalic, succinic and fumaric acids and among phenolic compounds, only vanillic acid showed significant interactions particularly with genotypes YYU-1, YYU-10 and YYU-13. As a result of the study, it was concluded that the determined genotypes are prominent in terms of quality fruit production in saline and arid areas, and it is necessary to examine these genotypes using different parameters in different breeding studies.

The study was conducted with a factorial design comprised of 9 treatments, with 4 replications of 40 plants per treatment. Study findings demonstrated that there were significant differences among the cultivar yields and fertilizer applications, where applications 2 and 3 led to significant increases in yield parameters. Furthermore, especially the fertilizer applications 2 and 3 provided the best results in most studied parameters.
Düşük Doz Gama (60co) Işını Uygulamalarının Kısıtlı Sulama Koşullarında Taze Fasulyenin Erken Fide Gelişimine Etkilerinin Belirlenmesi
(2023) Ekincialp, Aytekin; Yıldız, Muhsin; Erdinç, Çeknas
Kuraklık stresi, pek çok kültür bitkisinde olduğu gibi taze fasulye üretimini de sınırlayan başlıca faktörlerden biridir. Son zamanlarda düşük dozda gama ışını uygulamalarının bitki gelişiminin kritik aşamalarında kuraklığın oluşturduğu olumsuz etkinin elemine edilmesinde yardımcı olduğu bazı araştırmacılar tarafından bildirilmiştir. Fakat bu konuda yapılan çalışmalar oldukça sınırlıdır. Bu çalışmada farklı gama ışın dozları (0, 25, 50 ve 100 Gy) uygulanan Gina ve Romano taze fasulye çeşitlerinde kısıtlı sulamanın etkilerinin belirlenmesi amaçlanmıştır. Fideler iklim odası koşullarında 23 ± 2°C sıcaklık ve 16:8 ışık:karanlık periyodunda tam sulama [%100 (I1)] ve kısıtlı sulama [%50 (I2)] olacak şekilde iki farklı sulama seviyesinde yetiştirilmişlerdir. Çalışma sonunda gama ışını dozları ile kısıtlı sulamanın sürgün ve kök boyu, yaprak sayısı, sürgün ve kök yaş-kuru ağırlıkları, kök-sürgün oranı gibi fide gelişim parametrelerinin yanı sıra yaprak oransal su içeriği, fotosentetik pigment içeriği, lipid peroksidasyonu ve sürgün besin elementi içeriklerine etkisi araştırılmıştır. Çalışmada düşük doz gama uygulamasının kısıtlı sulama koşullarında çeşitlere göre farklı sonuçlar verdiği görülmüştür. Gama ışın dozları %50 sulamada Gina çeşidinde kök boyunda önemli bir etki yaratırken, Romano çeşidinde 50 ve 100 Gy dozlarının sürgün boyu ile yaş ve kuru ağırlıklarda önemli bir artış sağlamıştır. MDA içeriği her iki çeşitte de su stresinde 50 ve 100 Gy gama ışını ile birlikte önemli miktarda azalmıştır. Düşük doz gama ışını uygulamasının özellikle Romano çeşidinde daha etkili olduğu ve genel olarak 50 ve 100 Gy gama ışın dozlarının kısıtlı sulamada uygulanabilir dozlar olduğu belirlenmiştir.

(Tubitak Scientific & Technological Research Council Turkey, 2012) Tufenkci, Sefik; Demir, Semra; Sensoy, Suat; Unsal, Husameddin; Demirer, Emre; Erdinc, Ceknas; Ekincialp, Aytekin
The effectiveness of different arbuscular mycorrhizal fungi (AMF) on different hybrid cucumber cultivars has not been well documented, even under normal seedling conditions. The present study therefore aimed to evaluate colonization, nutrient uptake, dependency, and other seedling traits of 4 cucumber hybrids (Ceren F-1, Beta F-1, Silyon F-1, and Maraton F-1) inoculated by 3 different AMF [Glomus intraradices (Gi), Glomus etunicatum (Ge) and Gigaspora margarita (Gm)]. Traits were evaluated in a growth chamber experiment consisting of a 4 x 4 factorial design (4 cucumber hybrids, 3 AMF plus 1 control) with 3 random replications. AMF-inoculated cucumber seedlings had shorter hypocotyledons and wider and longer cotyledons than non-inoculated seedlings. Gm-inoculated seedlings had the narrowest stem diameter and lowest leaf number. AMF-inoculated seedlings had shorter shoots and longer roots than noninoculated ones. There was significant mycorrhizal effect on the iron (Fe) content of shoots and the mycorrhizal colonization rate in roots. Relative mycorrhizal dependency (RMD) varied widely among the hybrid cucumber cultivars tested. It is thought that the determination of high-RMD cultivars could lead to improvements in cucumber seedling production in the future.
Effects of Chemical and Organic Fertilizer Combinations on Bioactive Compounds and Macro-Micro Nutrients in Bell Pepper (Capsicum Annuum L.) Fruits
(Univ Life Sciences Lublin, 2024) Ekincialp, Aytekin
This study aimed to identify strategies that are conducive to both sustainable and high-yielding horticulture, with a focus on minimizing ecological damage by reducing dependence on chemical fertilizers. Sumo F1 bell pepper variety was used in an open-field experiment. The effect of three distinct fertilizer types (earthworm vermicompost Yara Tar & imath;m, organomineral fertilizer Hektar, chemical fertilizer G & uuml;bretar) and their respective combinations on biochemical, nutrient and color parameters of bell pepper fruits was evaluated. It was observed that biochemical values and nutrient levels were higher in treatments with vermicompost at 25, 50, 75 and 100% rates. The highest levels of organic acids (malic acid, succinic acid, fumaric acid, tartaric acid), polyphenols (chlorogenic acid, ferulic acid), total antioxidants, and nutrient elements (phosphorus, potassium, zinc) were obtained in treatments without chemical fertilizer. The results show that the use of organomineral fertilizer, especially vermicompost, plays a role in reducing the dependence on chemical fertilizer in bell pepper cultivation.

(Tubitak Scientific & Technological Research Council Turkey, 2021) Erdinc, Ceknas; Ekincialp, Aytekin; Turan, Sibel; Kocak, Metin; Baloc, Faheem Shahzad; Sensoy, Suat
Approximately 30% of plant species of Turkey, which is among the richest countries in terms of biodiversity, has been endemic. Wild rhubarb (Rheum ribes L.) is a wild vegetable grows especially in the eastern region of Turkey and is an endemic species. In this study, genetic relationships among 80 wild rhubarb genotypes collected from some regions of Lake Van Basin, which are in the distribution area, were tried to be determined by iPBS marker system. At the same time, a commercial variety of R. rhabarbarum, which is a cultivated species, was used as control. PCR studies were conducted with 23 iPBS primers to determine genetic relationships, and a total of 340 scorable bands were obtained. 100% polymorphism rate was obtained from all primers studied. While the average PIC value was found to be 0.90, the highest value was found to be 0.97 from the primer # 2220. It was determined that the genotypes were divided into 3 basic groups in the dendogram created with UPGMA based on Jaccard similarity coefficient.

(Friends Science Publishers, 2019) Ekincialp, Aytekin; Erdinc, Ceknas; Turan, Sibel; Cakmakci, Ozlem; Nadeem, Muhammad Azhar; Baloch, Faheem Shehzad; Sensoy, Suat
Rheum ribes L. (wild rhubarb) is one of the less known plants to the world and the only species from the Rheum genus present in Turkey. In this study, one R. rhabarbarum (as check genotype) and 80 R. ribes genotypes were collected from different geographical locations of Turkey for the investigation of diversity and genetic structure using ISSR (Inter Simple Sequence Repeat) and SSR (Simple Sequence Repeats) markers. SSR markers reflected higher (100%) polymorphism as compared to the ISSR marker. However, ISSR markers produced higher average Polymorphism Information Content (PIC) value (0.805) than the SSR markers (0.724). A Similar range of (PIC) values with ISSR markers was found greater (0.935-0.395) as compared to the range of SSR makers (0.88-0.47). Using Jaccard similarity index, genetic distance was measured for both markers and average genetic distance was found to be higher with ISSR markers as compared to the SSR markers. Neighbor-joining analysis clustered genotypes into 3 groups for both marker systems. During this study some distinct genotypes like R. rhabarbarum, YYUERC19, YYUERCO9 and YYUNIER65 were investigated that can be used as candidate parents for the development of R. ribes L. varieties. Structure analysis grouped the genotypes according to altitude by clustering genotypes having at more than 2000 m in one group and genotypes less than 2000 m altitude in another group. Genetic variations observed in this study can be applied to investigate various traits of interest for the R. ribes L. breeding. (C) 2019 Friends Science Publishers
The Impact of High Temperatures on Some Plant Growth Parameters in Some Common Bean Genotypes
(Hard, 2022) Kabay, Turgay; Ekincialp, Aytekin; Sensoy, Suat
Common bean is one of the most cultivated vegetables globally and in Turkey. Especially in areas with a temperate climate, the losses in productivity and quality limit production due to high temperatures. Thus, the present study aimed to determine the bean genotypes tolerant to high temperature stress and to reduce the above-mentioned yield and quality losses to benefit the researchers and producers. In the present study, 46 bean genotypes and 2 bean cultivars, determined to be tolerant and sensitive to high temperatures in previous studies, were used. Variations in 0-5 visual scale value, plant fresh and dry weight, root fresh and dry weight, stem diameter, plant height, leaf number and area, relative leaf water content, membrane damage index and ion (K and Ca) content were determined in bean plants. Bean seeds were sown in 2-liter pots containing 2:1 peat + perlite mixture, 3 plants per pot based on the randomized blocks experimental design. From the seed sowing until the first real leaf appearance, the pots were irrigated with tap water and then, the pots were irrigated with Hoagland nutrient solution. The control plants were grown in a polyethylene greenhouse and the plants subjected to high temperature were grown in an extra polyethylene covered high tunnel in a polyethylene greenhouse to create high temperature stress. There was a daytime temperature difference of 6 degrees C (optimum: 32.17 degrees C for high temperature application; optimum: 26.17 degrees C for control application) between the control and high temperature applications. The analyzes conducted on the plants revealed that the genotypes V21, V28, V32, V82, T65, and V-a1 and cv. Yakutiye were tolerant to high temperature stress, while the genotypes V88, V89, T7, and T72 and cv. Zulbiye were the sensitive ones.
The Impact of Low Temperatures on Plant Growth in Some Common Bean Genotypes
(Parlar Scientific Publications (p S P), 2018) Kabay, Turgay; Ekincialp, Aytekin; Erdinc, Ceknas; Sensoy, Suat
In plant production, when the plant is exposed to any biotic and abiotic stress during the process from planting to harvest, a deficiency is observed in plant growth. Especially in plants with high temperature requirements, low temperatures lead to damages in plant shoots and roots. Thus, the present study aimed to determine low temperature tolerant bean genotypes in order to provide convenience for the producers and researchers. Among 21 bean genotypes exposed to low temperature stress, plant fresh and dry weight, stem diameter, plant height, leaf number and area, leaf relative water content, membrane damage index and ion (K and Ca) content were determined. Bean seeds were sown in 2-liter pots containing 2: 1 peat + perlite mixture, and 2 plants per pot. The plants that were exposed to low temperature stress were sown in a high tunnel on March 15, when the external temperatures were low, and irrigated with water containing Hoagland nutrient solution. When the bean seedlings were 20 days old, the half of pots were removed from the high tunnel and exposed to low temperatures outside for 20 days. On the 40th day, the experiment was terminated, and it was determined that the genotypes C19, C18, and C30 beside cv. Yakutiye were resistant to low temperature stress, while the genotypes A90, A97, A67, and C13 beside cv. Zulbiye were susceptible to low temperature stress.
The Impact of Potassium Sulphate Application on Phaseolus Vulgaris Plants Grown Under Salt Stress
(Parlar Scientific Publications (p S P), 2018) Erdinc, Ceknas; Sonmez, Ferit; Ekincialp, Aytekin; Sensoy, Suat
The present study aimed to investigate the effects of potassium sulphate on certain bean genotypes after K2SO4 application based on the analysis of plant growth parameters and macro-micro nutrient element content. The study material included 1 bean genotype (Gevas) and 3 bean cultivars (Akman-98, Sugar and Onceler) obtained in Lake Van Basin of Turkey. The plants were grown under controlled conditions at 23 +/- 2 degrees C temperature and 8000 lux light intensity 12 hours light and 12 hours dark photoperiods, with 4 replicates and 8 plants per replicate and randomized lots design. The plants were grown under stress-free conditions until they reached the 3-leaf stage, after which they were exposed to a constant 20 mM salt stress. 500, 1000 and 2000 mg kg(-1) K2SO4 was mixed to the growth medium before seeding except the control plants. Study findings demonstrated the statistical significance of potassium sulphate application especially that of the 1000 mg kg(-1) and 2000 mg/kg-1 potassium sulphate doses, based on several parameters and its effects on the reduction of salt stress were observed. The variations between the genotypes were observed and it was determined that the genotype Gevas and cv. Onceler exhibited higher tolerance. Despite the other parameters, the nutrient element parameters such as K/Na and Ca/Na content and plant development parameters such as shoot dry matter and root dry matter content were effective in determination of the positive effects of potassium sulphate.

(Agricultural Research Communication Centre, 2018) Ekincialp, Aytekin; Sensoy, Suat
In this study. the resistance levels to anthracnose disease [Colletotrichum lindemuthianum (Sacc. and Magnus) Lambs. Scrib.] of 92 bean genotypes collected from different parts of the Lake Van Basin were investigated by artificial inoculation and molecular markers. The resistance levels of bean genotypes to the isolate 11# of anthracnose disease were determined by classical inoculation method in a climate chamber condition, and the presence of resistance gene related markers in bean genotypes was determined by using four SCAR primers [SAS13 (950 bp, Co-4(2)), SC08 (910 bp, Co-4), SF10 (1072 bp, Co-10), SZ04 (567 bp, Co-6)] and one RAPD [OA18(1500) (1500 bp, Co-1(5))] primer. In the artificial inoculation, the bean genotypes were evaluated according to the 0-9 scale, and the four of them having a value between 0 and 3 were found as resistant to this isolate of anthracnose, but the rest of them having a value between 4 and 9 were determined as sensitive. With molecular markers, it was found that the 82 bean genotypes had the resistant Co-4(2) allele; the 54 bean genotypes had the resistant Co-4 allele; the 6 bean genotypes had the resistant Co-10 allele; the 36 bean genotypes had the resistant Co-6 allele; and the 15 bean genotypes had the resistant Co-1(5) allele. The only bean genotype having all resistance markers was the genotype G81, whereas the bean genotypes G27, G28, G40, G76, and G86 had no resistance associated molecular markers.
Rhizoctonia Species, Anastomosis Groups, and Pathogenicity Isolated From Common Bean in Lake Van Basin, Turkiye
(2024) Durak, Emre Demirer; Erdinç, Çeknas; Ekincialp, Aytekin
Common bean (Phaseolus vulgaris L.) is an important vegetable crop grown in Lake Van Basin. Local genotypes are widely grown in the region. Rhizoctonia root rot induced by Rhizoctonia solani Kühn is an important soilborne plant disease that leads to global economic losses as well as in Turkey. The present study was conducted to determine anastomosis groups and pathogenicity of Rhizoctonia spp. obtained from bean plants in Lake Van Basin in 2013 and 2014. A total of 236 Rhizoctonia isolates in 5 anastomosis groups were obtained from bean plant roots. It was observed that AG- 4 (112) was the most isolated group in beans, followed by AG- 2 (41), AG- 3 (28), AG- 5 (33), and binucleate AG- K (22) isolates. Pathogenicity test conducted in thirty isolates in 5 anastomosis groups was analyzed for A64 (Bitlis/ Adilcevaz), TR68557 genotypes, and Gina (cv.) under growth chamber conditions. The study findings demonstrated that all tested isolates could infect the bean plant with different degrees of severity; however, the most virulent group was AG- 4. It was determined that the most virulent isolate was Isolate No. 19 in the A64 genotype, Isolate No. 2 in TR68557, and Isolate No. 18 in Gina cv. in in vivo tests. The identification and pathogenicity determination of Rhizoctonia isolates are the first steps towards an efficient control strategy for bean diseases caused by Rhizoctonia species. In order to obtain quality and productive products in the Van Lake Basin, where intensive bean production is carried out, precautions should be taken by considering the damage caused by Rhizoctonia spp. on plants.

(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2025) Demirer Durak, Emre; Ekincialp, Aytekin; Gunes, Hasret; Erdinc, Ceknas
Beans (Phaseolus vulgaris L.), one of the main vegetables common in the Van Lake Basin, are frequently grown in the region with local genotypes. Rhizoctonia solani root rot, an important soil-borne disease that negatively affects beans, especially in this region, causes economic losses in our country and worldwide. Therefore, a viable and eco-friendly alternative to chemical control in the treatment of such significant soil-borne plant diseases is the application of Arbuscular Mycorrhizal Fungi (AMF). This study aimed to investigate the effects of commercial AMF (ERS) and Funneliformis mosseae (Fm) against R.solani (Rs) root rot disease in V29 and TR 50763 (T71) bean genotypes obtained from Van-Geva & scedil;. For this purpose, some plant growth parameters, total phenol, total antioxidant capacity, root colonization, and disease severity parameters were investigated. Fm and ERS significantly increased plant morphological parameters and reduced disease severity in both bean

Van Gölü havzasının değişik yörelerinden toplanmış olan 95 fasulye genotipinin genetikakrabalık ilişkileri hem fenotipik hem de moleküler yöntemlerle incelenmiştir. Fenotipikyöntemde, 71 adet morfolojik özellik incelenmiş ve bunlar arasında yüksek korelasyongösterenler değerlendirme dışı bırakılarak fasulye genotiplerine ait 61 adet ölçüm veyagözlemden yararlanılmış; moleküler yöntemde ise 28 primerden elde edilen 219 adetpolimorfik ISSR belirteci ve 10 primerden elde edilen 76 adet polimorfik RAPD belirtecikullanılmıştır. Fasulye genotipleri arasındaki genetik akrabalık dereceleri, fenotipik vemoleküler veriler kullanılarak elde edilen değişik matrislerden (Öklid ve Jaccard katsayımatrisleri) dendrogram oluşturularak incelenmiştir. Fenotipik olarak incelenengenotiplerin %69,5’inin Güney Amerika (Andean) ve %30,5’inin Orta Amerika(Mesoamerican) orijinli olduğu ve genotipler arasında yüksek genetik çeşitliliğin olduğusaptanmıştır. Fenotipik ve moleküler verilerin birlikte incelenmesi sonucunda, GüneyAmerika ve Orta Amerika orijinli genotiplerin; bodur ve sırık genotiplerin; beyaz, diğertek renkli ve çok renkli tohumlara sahip genotiplerin ayrı kümelenmelerde yer aldıklarıgözlenmiştir.

This study evaluated seedling traits (shoot/root length, fresh and dry weights of shoots/roots, number of leaves, shoot diameter), phosphorus (P) content, mycorrhizal colonization (MC), and relative mycorrhizal dependency (RMD) of 21 common bean genotypes inoculated by 4 different arbuscular mycorrhizal fungi (AMF) [Glomus intraradices (Gi), Glomus mosseae (Gm), Gigaspora margarita (Gim), and commercial AMF (cAMF)] in a growth chamber under controlled growing conditions. With the exception of shoot diameter, inoculated plants had better seedling traits than noninoculated plants. P content of shoot was also higher in inoculated plants than in noninoculated plants. Of the 20 genotypes and Nadide cv. examined, 5 responded positively and 3 responded negatively to inoculation with all AMF types. Great variations in RMD and MC were observed, with the highest RMD and MC in the T120 (69.54%) and T71 (81.09%) genotypes and the lowest in the V77 (1.26%) and V78 (31.42%) genotypes. Positive correlations were found between RMD and seedling traits, with the exception of shoot length as well as root length, P content, and colonization. MC was significantly correlated only with P content.
