    Effects of Salicylic Acid Seed Priming on Germination of Lentil (Lens culinaris Medik.) Exposed to Salt Stress
    (Hasan ÖNDER, 2024) Kamçı, Gizem; Bicer, Behiye Tuba; Başdemir, Fatma
    Lentil (Lens culinaris Medik.) is an essential crop globally, particularly in Türkiye, West Asia, Southern Europe, India, and Africa. Lentil is a valuable food source, rich in proteins, carbohydrates, minerals, and vitamins. However, lentil production faces challenges due to salinity stress, which hampers water uptake and causes toxic effects on plants. The study aimed to investigate the effects of salicylic acid (SA) seed priming and varying salt (NaCl) concentrations on the germination and development of lentil seeds. The research was conducted in the Field Crops Biotechnology Laboratory, University of Dicle, Faculty of Agriculture, Türkiye. In the research, control, two salt (NaCl), four salicylic acid (SA) doses and their combinations were used on Lens culinaris variety called İlke. Germination percentage, energy, rate index, mean germination time, peak value, and vigor index were calculated. The results demonstrated that SA had a significant impact on improving lentil germination under salt stress conditions. Specifically, lower concentrations of NaCl combined with SA showed positive effects on germination and growth parameters compared to higher NaCl concentrations. The highest germination percentage, energy, and rate index values were in the control and 0.25 SA dose treatment. Salicylic acid doses under 50 NaCl concentration exhibited higher germination percentage, energy, and rate index values than under 100 NaCl. Increasing SA and salt doses negatively affected lentil seed germination. This finding is significant for lentil cultivation in salt-affected areas, offering a potential strategy to improve crop resilience and yield in challenging environmental conditions.

    Evaluation of yield and yield components of some Turkish maize landraces grown in south eastern Anatolia, Turkey by biplot analysis
    (Life Sciences Soc Pakistan, 2019) Kizilgeci, Ferhat; Albayrak, Onder; Yildirim, Mehmet; Akinci, Cuma; Bicer, Behiye Tuba
    Maize has comparatively high genetic diversity. Thus, we evaluated yield and yield traits on 92 maize landraces collected from Black Sea and Marmara Regions of Turkey and investigated three maize hybrids for yield and some morphological traits under Diyarbakir conditions in 2016 growing season. Mean value of plant height varied between 131-270 cm among maize landraces, 62.33-177cm for first ear height, 13.07-24.70 mm for stalk thickness, 9.04-22 cm for ear length, 10.70-44.16 mm for ear diameter, 7.33-16.80 for row number of ear(-1), 10-44.60 for the number of kernels in row(-1), 16.43-27.46 mm for rachis diameter and 1387-18226.7 kg ha(-1) for grain yield. According to our finding of the hybrid and the local maize genotypes, the grain yield, the number of grains in the cob and the weight of the cob, plant height, and number of rows were collected in the single group in the biplot chart. DZM-194-2 and DZM-11 local maize genotypes were found more stable for all investigated traits. DZM-7, DZM-194-2, DZM-11 and DZM-222-4 genotypes shown superiority to other genotypes in terms of grain yield.

    EVALUATION OF YIELD TRAITS, QUALITY PARAMETERS AND SEED YIELD STABILITY FOR LENTIL GENOTYPES UNDER DIFFERENT LOCATIONS IN TURKEY
    (Parlar Scientific Publications (P S P), 2019) Kizilgeci, Ferhat; Bicer, Behiye Tuba; Yildirim, Mehmet; Akinci, Cuma; Albayrak, Onder; Bayman, Serkan
    Lentil is conventionally grown as a rain fed crop, mostly in the Middle East; it's a rich source of protein for human feeding. Yield, seed quality, adaptability and chalky spot syndrome of fifteen lentil genotypes and five lentil cultivars were evaluated in the South-Eastern Anatolia of Turkey. Yield and yield trails as well as seed quality such as protein content, seed rate with chalky spotted and germination rate for of all genotypes were varied significantly. Seed yield were varied from 1337 to 2142 kg/ha among the genotypes. While cultivar 'Sakar' produced the maximum yield and cultivar 'BM 848' produced the minimum seed yield. It was also revealed that genotypes 'ILL10975', 'FLIP2010-94L' and cultivar 'Sakar' was found the most sensitive to cold. Lentil crops with chalky spotted were detected in Adiyaman location and its rate ranged from 42% to 13%. Genotype x environment interaction was significant for seed yield and different stability parameters were computed for genotype adaptability. Ecovalance (W(2)i) and stability variance (sigma(2)i) were low value in genotypes ILL 3375 and Kafkas, but Firat 87 had high values.

    SEED GERMINATION RATE IN LENTIL (LENS CULINARIS) WITH CHALKY SPOTTED
    (Parlar Scientific Publications (P S P), 2017) Bicer, Behiye Tuba; Toncer, Ozlem; Kavak, Hamit; Akinci, Cuma
    The chalky spot syndrome is a serious seed quality problem in red lentil in the southeast Anatolia of Turkey. This research was carried out to determine the chalky spot rate and its effect on the seed germination in twenty lentil genotypes. Germination tests as three groups performed; (i) seeds from damaged location were cleaned, and two groups were divided as damaged and non-damaged, (ii) all seeds from damaged location, and (iii) seeds from non damaged location. Chalky spot rate among genotypes ranged from 11.0 to 42.92%. Mean of germination speed in damaged seeds was 46.88%, and ranged from 20 to 66% in damaged seeds. Mean of germination speed in non-damaged seeds was 84.5%. Chalky spotted seed rate strongly reduced germination rate.
