(Centenary University, 2020) Şelem, E.; Nohutçu, L.; Tunçtürk, R.; Tunçtürk, M.
Although Allium species are used in a wide variety of fields, they are frequently preferred as dry or fresh spices for intestine disorders, loss of appetite, for regulating blood sugar, pain reliever, wound healing, acne treatment and herby cheese making in the Eastern Anatolia region. In this study, it was aimed to determine of morphological measurements (plant length, stem length and diameter, leaf length and diameter, number of leaves, umbella diameter, pedicel length), stoma and pollen characteristics and pollen viability of some Allium species which are used extensively in our country especially due to their aroma and antimicrobial properties. Allium akaka, A. giganteum, A. kharputense, A. scorodoprasum subsp rotundum, A.vineale and A. sintensii species collected from their natural habitat they were cultivated and planted in plots prepared in the Van Yüzüncü Yıl University Medicinal and Aromatic Plants Garden during the field trips from Van and surrounding cities in 2016. As a result, according to the measurements and evaluations made in the observation plots where the plants are located, it has been observed that there is a good adaptation in terms of morphological features, it was determined that A. kharputense and A. sintensii species showed a weaker growth than others. In terms of pollen amount and vitality, which is an important parameter in high seed yield, it was observed that A.vineale and A. scorodoprasum subsp. rotundum species came to the fore. It has been observed that stomata, which play an important role in adaptation and photosynthesis, have the highest density of A. kharputense species and the highest measure is A. vineale. © 2020, Centenary University.

Effect of Mycorrhiza Applications on Some Physiological and Macro-Micro Element Contents in Soybean (Glycine Max L.) Grown Under Salt Stress Condition
(Centenary University, 2025) Oral, E.; Tunçtürk, R.; Tunçtürk, M.; Nohutçu, L.; Şelem, E.
This study was carried out to determine the effects of mycorrhizal applications on some biochemical and macro/micro nutrient characteristics of soybean (Glycine max L.) under salt stress (0, 50, 100, 150, 200 mM NaCl). In the research investigated chlorophyll a (17.30-22.61 µg g-1 TA), chlorophyll b (3.05-5.78 µg g-1 TA), total chlorophyll (20.46-27.72 µg g-1 TA), carotenoids (3.57-4.72 µg g-1 TA), proline (0.43-1.81 µg g-1 TA), malondialdehyde (MDA) (13.1-18.3 nmol g-1), and several macro-and micro-elements, including Ca (9.43-12.8 g kg-1), K (9.97-11.8 g kg-1), Na (0.94-3.52 g kg-1), P (1.49-2.44 g kg-1), Mg (3.03-3.46 g kg-1), Zn (3.71-7.63 g kg-1), K/Na ratio (3.32-7.17%), Mn (23.6-56.5 g kg-1), Mo (0.81-1.26 g kg-1), Cu (0.76-1.78 g kg-1), As (2.17-5.26 g kg-1), Ni (0.99-1.97 g kg-1), Pb (0.07-0.12 g kg-1), Cd (0.06-0.13 g kg-1), Co (0.06-0.08 g kg-1) and Cr (0.78-1.48 g kg-1). As a result of the study; a decrease or an initialincrease followed bya decrease was observed inin chlorophyll a and b, total chlorophyll, carotenoids, P, Zn, K/Na, Ca/Na, Mn, Mo, Cu, As, Ni, Pb, Cd, Co and Cr contents in mycorrhiza-treated plants under salt stress. The levels of Ca, K and Na increased, while Mg levels remained statistically insignificant, following a fluctuating pattern.. Additionally, boron applications were found to increase the nitrogen balance index, MDA, flavonol, anthocyanin, antioxidant and phenolic contents. Overall, the study demonstrated that mycorrhiza applications have a beneficialand regulatory effect on the biochemical composition and macro/micro-element levels in soybean under salt stress. © 2025, Centenary University.

The Effect of Plant Growth Promoting Rhizobacteria Applications on Some Growth Parameters and Physiological Properties of Marigold (Calendula Officinalis L.) Plant Grown Under Drought Stress Conditions
(Centenary University, 2021) Şelem, E.; Nohutçu, L.; Tunçtürk, R.; Tunçtürk, M.
Calendula officinalis L. species, which has an important place among medicinal plants, is used in the pharmacology, food, ornamental plant, and cosmetics industry. In recent studies, It is known that the usage areas of marigold have become increasingly widespread, but despite this widespread use, the species is quite limited of commercial production. Against drought stress, which is an important abiotic stress factor in agricultural production, BGUB (plant growth-promoting rhizobacteria) applications have come to the fore in order to minimize the decrease in yield and quality. In this study, it is aimed to determine the effects of PGPR (B0: Bacteria-free environment (control), B1; Azospirillum lipoferum, B2: Bacillus megaterium, B3: Chlorella saccharophila) applications on some growth parameters and physiological changes of C. officinalis plant grown under drought stress (normal irrigation (K1), reduced ½ (K2) ve reduced ¾ (K3)) conditions. The study was carried out in a controlled climate room with a temperature of 25o C and a humidity of 65% in a dark/light photoperiod of 8/16 hours. Seeds were sown on 28.05.2020 and were subjected to analysis of variance in randomized plot design and 3x4 factorial design. In this study, it is aimed to determine the effects of BGUKB (B0: Bacteria-free environment (control), B1; Azospirillum lipoferum, B2: Bacillus megaterium, B3: Chlorella saccharophila) applications on some growth parameters and physiological changes of C. officinalis plant grown under drought stress (normal irrigation (K1), reduced ½ (K2) ve reduced ¾ (K3)) conditions. Considering the parameters examined, drought applications were found to be statistically significant in terms of stem length (K1: 11.1 cm), root fresh (K1: 1.06 g) and dry (K1: 0.17 g) weight, stem fresh (K1: 7.26 g) weight, leaf area (K1: 7.81 cm2) and temperature (K3: 27.7o C), epidermal cell number (K1: 593.16 number/mm2 and all stomatal characteristics. In conclusion, bacteria applications showed a significant impact on some of the characters like stem length (B1: 11.0 cm), root fresh (B1: 0.89 g) weight, stem fresh (B1: 6.09 g) weight, epidermal cell number (B1: 672.88 number mm-2), stoma length (B1: 32.71 µ) and density (B1: 11.06 number (mm2). © 2021, Centenary University.
