(Centenary University, 2016) Ekincialp, A.; Erdinç, Ç.; Eser, F.; Demir, S.; Şensoy, S.
This study was carried out to assess the effects of two different Arbuscular Mycorrhizal Fungus (AMF), humic acid (HA) and whey applications on various plant and yield characteristics in melon (Magnum-F1), watermelon (Wonder-F1) and summer squash (Focus-F1) species. At trials implemented in the field, 5 different applications [1-) Control, 2-) AMF, 3-) AMF+Whey, 4-) AMF + HA, and 5-) AMF + Whey + HA] were applied at 4 replications according to randomized block design for all three types of vegetables species. The applications on melon were significant for average yield (28 430 - 41 240 kg ha-1) and average branch length. The applications were significant on watermelon in terms of average yield (51 460-86 580 kg ha-1), average branch length (124.75-165.75 cm), fruit pedicle length; and on summer squash in terms of average yield (27 660-34 540 kg ha-1), TSSC (8.99-10.25 brixº), and weight of fresh leaves. It was observed that the 5th and 4th applications were more superior to the others. According to average yield, especially, the fifth application had the highest mean for all three species. © 2016, Centenary University. All rights reserved.

Effects of Salt Stress on Some Nutrient Content and Total Antioxidant and Total Phenol Content in Different Bean Genotypes
(Centenary University, 2019) Kipçak, S.; Ekıncıalp, A.; Erdınç, Ç.; Kabay, T.; Şensoy, S.
In this study, the effects of salt stress on 20 bean genotypes collected from Lake Van Basin were investigated. The salt application was treated in 0 mM, 25 mM and 50 mM NaCl concentrations, and then the plants were grown in growth chamber conditions. To determine the effect of stress, total antioxidant capacity, total phenolics and some nutrient elements content (P, Mg, Fe, Cu, Mn and Zn) were evaluated. In the parameters examined in terms of tolerance to the salt, the genotypes showed different responses. When the rate of change of the plants response to salt stress according to control was examined, it was determined that with the increase in salt doses, total phenolic and total antioxidant capacity decreased at high rate and salt stress had a negative effect on genotypes. It was found that the contents of P in both doses and Fe at 50 mM were increased in shoot, while the contents of Mg, Cu and Zn at 25 mM and 50 mM, Mn at 50 mM were decreased. In the root, the contents of Fe, Mg and Mn were decreased at 25 mM, and P, Mg, Cu, Mn and Zn contents were detected to increase with the increase in salt doses as well as. The genotypes G9 and G30 showed high levels of tolerance in both salt concentrations and the genotypes G31, G49 and G94 were found to be sensitive to both 25 mM and 50 mM salt concentrations. © 2019, Centenary University.

Enzyme, Chlorophyl and Ion Changes in Some Common Bean Genotypes by Drought Stress
(Centenary University, 2016) Kabay, T.; Şensoy, S.
In recent years, as a result of the increase in drought, one of the most important abiotic stress conditions, large declines have been observed in the yield and quality of agricultural products. The solution will be much easier if the drought damage in crops has to be defined well. Scientific studies have been carried out in order to minimize the decrease in yield and quality. The present study aimed to determine the enzyme and ion changes in common bean, an important product consumed and enjoyed a lot in the world and our country, during drought stress. Drought stress has been created by cutting irrigation water gradually for common bean plants grown in pots containing 2:1 peat + perlite mixture. The enzyme and ion level changes in the drought tolerant (Yakutiye and V-a1) and in drought sensitive (Zulbiye and T7) bean genotypes have been analyzed in five different periods of drought stress. The changes in the level of catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), malondialdehyde (MDA), chlorophyll-a, chlorophyll-b, the total chlorophyll, K, Ca and Na were examined on the 0th, 2nd, 4th, 6th and 8th days of the drought stress. Obvious differences have been observed for these examined parameters in drought tolerant and susceptible genotypes. © 2016, Centenary University. All rights reserved.
Morphological Characterization of A. Vineale
(Centenary University, 2021) Çakmakci, Ö.; Şensoy, S.; Alan, A.R.; Erdinç, Ç.
Allium vineale L. is a wild edible Allium species. This species is collected from nature by the local people in the Eastern Anatolia Region of Turkey and consumed as a vegetable. Aboveground organs of A. vineale plants are used in herbed cheese production in the eastern provinces. Collection from nature is not a sustainable way production of this species. A. vineale can be propagated via seeds and bulbils. It is suitable for cultivation under field and protected conditions. For agricultural production of this species, new cultivars with improved yield and quality traits have to be developed. In this study, an A. vineale germplasm was created with the aim of developing new cultivars that can be used in herbed cheese production. The accessions included in the germplasm were characterized for desired traits such as adaptability to culture conditions, agronomic characteristics and harvest uniformity. The phenotypic diversity of A. vineale accessions were examined using morphological descriptors derived from International Union for the protection of New Varieties of Plants (UPOV). According to the clustering and principal coordinate analysis (PCoA) made by evaluation of the morphological features, the accessions were divided into two main groups based on the locations. Germplasm accessions differ from each other for leaf waxiness and color intensity. A. vineale can be distinguished from other Alliums present in the same area with thin leaves, short plant height, and multiple bulbils in the flower scapes. © 2021, Centenary University.

Screening of Bean Genotypes Against Bean Common Mosaic Virus (Bcmv) by Artificial Inoculation and Molecular Confirmation
(Centenary University, 2023) Ibrahim, A.S.; Usta, M.; Şensoy, S.
Bean mosaic virus (BCMV) is a widespread plant pathogen that causes significant bean yield losses in several bean-growing regions worldwide. The use of resistant common bean varieties to BCMV is considered the most efficient and feasible approach to control its effects. Numerous genes and molecular markers associated with resistance to these pathogens have been discovered and used extensively in breeding studies around the world. Screening bean genotypes for resistance to these viruses is a critical step in developing resistant varieties. The goals of the study are to identify virus sources in the region and artificially inoculate Lake Van basin bean genotypes with BCMV. The recovered BCMV strain NL-4 was inoculated with 45 bean cultivars, most of which originated from the Lake Van basin in Turkey. Differentiation between resistant and susceptible was based on visual symptoms, and of the 45 genotypes, 29 were found to be resistant to NL-4, while 16 genotypes were susceptible (8 of them moderately susceptible and 8 of them highly susceptible). © 2023, Centenary University.
