    (Hard, 2023) Ceritoglu, Mustafa; Erman, Murat; Cig, Fatih; Ceritoglu, Figen; Ucar, Ozge; Soysal, Sipan; EL Sabagh, Ayman
    To deal with increasing salinization, plants show an array of responses such as root system architecture remodelling, thereby enhancing stress tolerance. Although various chemical, molecular and genetic techniques such that generally expensive and difficult applications are used to enhance stress tolerance, out of them, seed priming with suitable substrates is an easy-applicable and cost-effective treatment. The experiment aimed to evaluate the effects of salicylic acid (SA), silicon (Si), and sodium chloride (NaCl) priming on lentil seed germination parameters, seedling development, and root system architecture. In 2022, the experiment was carried out in the Field Crops Department laboratory at Siirt University in Turkey. Petri and pot investigations were part of the two stages of the experiment. Three concentrations of NaCl and priming treatments were utilized. Germination characteristics were impeded by rising saline levels. But seed priming, which boosted uniformity of germination by 50% as compared to unprimed seeds under saline stress, enhanced germination characteristics. A pot experiment revealed that the dry matter accumulation in roots was reduced by 24.6% due to salt stress. Si priming increased number of lateral roots by 32.6% compared to control seeds, whereas salt stress lowered it by 22.8%. The total length of lateral roots (TLLR) and mean length of lateral roots (MLLR) were inhibited by salinity stress by 75% and 63, respectively. Total root area was reduced by salinity stress by almost 70%, although seed priming increased it by as much as 29.3%. The SA and Si priming treatments improved germination stage and induced seedling growth by reducing salinity stress via more effective shoot development and root system architecture. In conclusion, seed priming with SA and Si is an affordable and sustainable method for reducing salt stress in lentil farming.

    Plant growth promoting bacteria enhances photosynthesis, nodulation and root system architecture in lentil under lead toxicity
    (Univ Zagreb, Fac Agriculture, 2022) Erman, Murat; Cig, Fatih; Ceritoglu, Figen; Ceritoglu, Mustafa
    The usage of plant growth-promoting bacteria (PGPB) in mitigation of harmful effects of lead (Pb) toxicity in plants and bioremediation of it from soils is a sustainable, effective and low-cost strategy. The experiment was laid out to investigate the role of PGPB on morphological and physiological growth, root system architecture and nodulation of lentil under Pb stress. The experiment was conducted according to completely randomized factorial design with four replications at the laboratory of the Field Crops Department, Siirt University, Siirt in 2022. The four Pb levels and three bacterial inoculations were used in the experiment. Plant height, seedling fresh weight, root fresh weight, seedling dry weight, root dry weight, total chlorophyll content, taproot length, number of lateral roots, total root length and number of nodule varied between 15.7-25.9 cm, 0.123-0.235 g, 0.019-0.092 g, 0.0104-0.0326 g, 0.0076-0.0146 g, 27.9-47.2%, 8.9-19.2 cm, 4.00-14.67, 17.6-44.8 cm and 1.37-10.63, respectively. Bio-priming with PGPB containing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity increased dry matter accumulation up to 56.1% and 22.9% in shoots and roots, respectively. Chlorophyll content enhanced up to 17.9% compared with control application. Besides, root system architecture and nodule formation were improved by bio-priming both under stress and non-stress conditions. Bio-priming with PGPB may be a sustainable solution to mitigate oxidative stress and promote plant growth and yield in lentil under Pb-contaminated soils.

    Root system variation of pulse crops at early vegetative stage
    (Univ Agr Sci & Veterinary Med Cluj-Napoca, 2020) Ceritoglu, Mustafa; Ceritoglu, Figen; Erman, Murat; Bektas, Harun
    Grain legumes known as Pulse crops are economically and nutritionally one of the most important crop families after cereals. Climate change and abiotic stress factors are limiting yield potential in these crops. Root system architecture, a neglected field, is promising for improved environmental adaptability and higher growth potential. Genotypes with deep and dense root system may cope better with water and nutrient limitations. This study aimed to evaluate 12 common cultivars from six different legume species. Root system architectures were evaluated under controlled conditions in a plexiglass system at the early vegetative stage. Roots were divided into four depth zones (0, 5, 10, 15> cm), and inter and intra species diversity were analysed. Significant diversity was obtained within and between the species. Bean, chickpea, and broad bean constituted deeper and dense root systems while lentil, soybean, and pea formed non-dense and shallower root systems. There was a significant correlation between earliness and early vegetative root vigour. The results of the study may provide a better understanding of the root system architectures of each species-genera. The results presented here may shed light on the selection of root traits in legume breeding programs.

    Screening of lentil genotypes during germination and early growth stages under PEG-induced drought stress
    (Inst Investigaciones Agropecuarias - Inia, 2024) Cig, Fatih; Erman, Murat; EL Sabagh, Ayman; Ceritoglu, Mustafa; Soysal, Sipan; Ucar, Ozge; Ceritoglu, Figen
    The objective of this experiment was to determine drought tolerance exhibited by lentil lines developed by the International Center for Agricultural Research in the Dry Areas (ICARDA) in an artificial environment, and to investigate the relationships between traits with various methods. This experiment examined 15 traits of 21 lentil (Lens culinaris Medik.) accessions grown under artificial drought stress created with polyethylene glycol (PEG)-6000 (0%, 10%, 15% and 20%) concentrations during germination and early seedling stages. Germination characteristics, seedling developmental properties and root system architecture traits were investigated to observed the impacts of drought stress. The originality lies in enabling the identification of drought-tolerant and sensitive genotypes through a brief and practical research method, while shedding light on the key traits by principal component analysis. The first two PCs explained 22.9% and 31.7% (total 54.6%) under optimal conditions while they described 14% and 58.3% (total 72.3%) under PEG-induced drought conditions, respectively. Variation in PC1 was mostly contributed by positive coefficients of germination index, uniformity of germination and germination energy, and negative coefficients of mean germination time. Variation in PC2 was mostly contributed by positive coefficients of seedling vigor index, root fresh weight and root dry weight. 'Tigris', G3664 and G3840 exhibited higher performance in terms of germination characteristics, while G3710, G3829 and G3840 produced higher DM accumulation, total biomass and lateral roots. Overall, PC-biplot denoted that selection based on germination index and seedling vigor index at germination and seedling stages would improve drought tolerance. In conclusion, genotypes G3840 and G3664 were identified as drought-tolerant, whereas genotypes G35, G3659, G3759, G3837, and G3844 were classified as drought-sensitive. In addition, G3664, G3840 and G3710 exhibited the highest stress tolerance index (STI) under artificial drought conditions.
