Determination of Biochemical Composition and Pigment Content in Legume and Cereal Microgreens
(Agricultural Research Communication Centre, 2021) Altuner, F.
Background: Legumes and cereals microgreens are consumed both in healthy nutrition and as a natural food against many degenerative diseases due to their rich bioactive content. The research was carried out to determine the biochemical contents of 5 legumes and 7 cereals. Methods: The research was conducted in Van Yuzuncu Yil University Field Crops Department Laboratory in 2020, in a controlled growing environment, according to the completely randomized experimental design. Total antioxidant activity, total phenolic, total flavonoid and total ascorbic acid contents and total Chlorophyll, Chlorophyll a, Chlorophyll b and Carotenoid contents and correlation between them were determined. Result: The differences between the means of all traits were found to be significant. The biochemical contents of cereals were 1.6-7 times higher than legumes. There was no big difference between the pigment values. In legumes, Bilensoy alfalfa had the highest total antioxidat activity and total flavonoid content, Uzbek lentil total phenolic content and Goynuk bean had the highest Total ascorbic acid. In cereals, Kirklar oat had the highest total antioxidat activity, total phenolic, total flavonoid and total ascorbic acid contents, while Larende barley had the lowest values (except total ascorbic acid content). While total Chlorophyll and Chlorophyll a amounts were highest in Kirklar barley and lowest in Uzbek lentils, the opposite situation occurred in Chlorophyll b and Carotenoid amounts. There was no significant correlation between biochemical parameters in legumes. There was a positive and significant correlation between total phenolic content with total antioxidant activity and between total ascorbic acid with total fenolic content in cereals. There were positive and significant correlations between all pigment parameters in both legumes and cereals.

(Centenary University, 2023) Salih, S.; Öngün, B.; Özdemir, B.; Oral, E.; Altuner, F.; Demir Atmaca, Ş.; Ülker, M.
Discovering the variation among genotypes is an important criterion for selecting the suitable cultivar for a certain environment. The study aimed to explore the genetic variation among 17 genotypes of barley based on grain yield and some related traits. Plants were grown under field grown conditions in the 2019-2020 and 2020-2021 growing seasons, and plant height (PH), spike per square meter (SSM), spike length (SL), spikelets per spike (NSS), seed per spike (SPS), biological yield (BY), grain yield (GY), and thousand grain weight (TGW) were measured. Results indicated that PH ranged (51.7 to 81.33 cm) and (58.20 to 79.90 cm), SSM (374 to 582) and (418 to 701), SL (7.10 to 9.63 cm) and (6.87 to 9.13 cm), NSS (9 to 15) and (8 to 17), SPS (21 to 49) and (21 to 51), BY (3466.7 to 5905.3 kg h-1) and (3731.7 to 6080 kg h-1), GY (1442 to 2192 kg h-1) and (811.8 to 1763.7 kg h-1), TGW (34 to 55.67 g) and (33.47 to 52.63 g) for the first and second year of experiment respectively. The advanced lines measurement values were higher in the second year of the experiment. It can be concluded that the advanced lines Anka-08 and Anka-11 are promising in most of the parameters. Some of the old and new cultivars still preserve their yield potential. © 2023, Centenary University. All rights reserved.
Impact of Different Sowing-Times of the Quinoa (Chenopodium Quinoa Willd.) and Its Varieties on the Yield and Yield Components in Turkey-Mardin Ecology Condition
(Corvinus Univ Budapest, 2019) Altuner, F.; Oral, E.; Kulaz, H.
This research was planned to determine the correct sowing times of quinoa (Chenopodium quinoa Willd.) varieties under the ecological conditions of Turkey-Mardin. The study was conducted in three different sowing times (15 March, 30 March and 15 April) using 2 quinoa varieties in aqueous conditions in 2017 spring period with three repetitions. At the end of the research; according to the data obtained, the number of plants in the harvest (15.4- 29.2 plants/m(2)), plant height (73.9-90.3 cm), the main panicle length (31.1-43.9 cm), the number of panicle branches (23.7-29.7 units plant), thousand weight (3.37-3.46 g), grain yield (125.6-1339 kg ha(-1)), hectoliter weight (6220-6280 kg ha(-1)) and crude protein ratio (14.8-15.7%) ranged. The highest grain yield was obtained from the application of Valiente and Titicaca (April 15) with 1345-1333 kg ha(-1), respectively. As a result of these properties, it was concluded that the most suitable planting time for quinoa (Chenopodium quinoa Willd.) cultivation in Mardin may be the second week of April.
The Impact of Salt (Nacl) Stress on Germination Characteristics of Gibberellic Acid Pretreated Wheat (Triticum Durum Desf) Seeds
(Corvinus Univ Budapest, 2019) Oral, E.; Altuner, F.; Tuncturk, R.; Tuncturk, M.
This research was conducted to examine the effects of gibberellic acid (GA3), which was treated to wheat (Triticum durum Desf) seeds before germination, on their germination and the seedling growth under saline conditions. Durum wheat Guney Yildizi variety, four different GA3 (0 (control), 100, 200 and 300 ppm), and four different salt (0 (control), 50 mM, 100 mM and 200 mM NaCl) concentrations were used in the research. Germination power, germination ratio (%), germination index, mean germination time, sensitivity index (%), radicula length (cm), plumula length (cm), radicula fresh weight (mg), radicula dry weight (mg), plumula fresh weight (mg), and plumula dry weight (mg) were examined. The results indicated that the increasing doses of salt prevented germination and growth parameters of wheat (Triticum durum Desf) seeds. It was observed that the doses of GA3 (Gibberellic acid), which were increased gradually before the doses of salt (NaCl), affected germination and growth positively and significantly. The best results of germination characteristics of wheat seed were obtained from the combination of 300 ppm Gibberellic acid + 0 mM (control) salt.

(Association of Agricultural Technology in Southeast Asia, 2022) Najafi, S.; Ulker, M.; Altuner, F.; Oral, E.; Ozdemir, B.; Jamal Salih, S.; Selem, E.
Karyotypic is studied within ecotypes species which are importantly found with different ecotypes, and it may possible showing specific genomic adaptation with their environmental growing conditions. Chromosome karyotype and morphology in wheat Tir by analyzing chromosomes in five ecotypes (Ahlat, Ercis, Muradiye, Patnos and central part of Van) in order to present the best instruction for cytogenetic studies in chromosome analysis was investigatred. Pre-treatment with %1 alpha-bromo naphthalene, fixation in karnoy 1, hydrolysis in NaOH and staining by %2 Aceto-Orcein were proved using root meristem segments followed by studying the microscopic preparations. Karyotype analysis of each ecotype. There was separately performed and showing several indices (TL: Total Length, LA: Long Arm, SA: Short Arm, Sat: Satellite and AR: Arm Ratio). The somatic chromosome numbers of all studied ecotypes are hexaploid with 2n=6x=42 and the averages of chromosomes length ranged from 4.60 ±0.02 µm to 16.05 ±0.02 µm. The longest chromosome was observed in chromosome number 1 from ecotype 3 which belongs to Muradiye and the shortest one was related to the chromosome number 21 from ecotype 4 from Patnos. © 2022 Association of Agricultural Technology in Southeast Asia.

Place in Turkey and Region of Wheat Agriculture İn Van Province, Problems and Solutions
(Centenary University, 2019) Altuner, F.; Oral, E.; ülker, M.
In the province of Van, wheat cultivation has made in the 787 314 da area, and in return has produced 104 44 thousand tons of production and has obtained 132 6 kg/da yield. This corresponds to half of the yield in Turkey (280 kg/da). İf the yield in te province can be increased to average of Turkey,the same production would be possible to produce in half amount of area. The main reason for the decrease in productivity in province is the use of local varieties instead of high-efficiency and high quality registered varieties in wheat agriculture. Since the local varieties has not preferred in the flour industry, the sector supplies 80% of the raw material needed from outside the province. However, very fragmented and small-scale agricultural business structure, tractors and equipment is lower than Turkey’s average current, the plurality of fallow fields, such as technical information and material deficiency in production of some problems, is seen as the obstacles of wheat cultivation in the province. Some measures to be taken in order to eliminate these obstacles and increase the yield and quality will result that every relevant sector can be satisfied in wheat production. © 2019, Centenary University.
