    (Parlar Scientific Publications, 2019) Yagci-Tuzun, Canan; Hacioglu, Burcu Tarikahya; Bulbul, Ali Savas; Arslan, Yusuf; Subasi, Ilhan
    Carthamus L. (Asteraceae) has been used in many secto rssuch as food, dye, cosmetic, biofuel industry and also used to cure many disease in traditional medicine. Within this study, it was aimed to present detailed anatomical characterization of five wild species of Carthamus grown in Anatolia, namely, C.dentatus Vahl., C.glaucus Bieb., C.lanatus L., C.persicus Willd. and C.tenuis (Boisand Balansa) Bornm. And to contribute to botanical and agricultural studies. Free-hand sections were taken from root, stem and leaf of each taxa. Sections were examined with light microscope and photographed by digital camera. Various measurements were taken on microscopic images. Variations on collenchyma to us cells in cortex, arrangements of scelerenchyma to us cells in vascular bundles, type of vascular bundles and state of the piths in stem; cuticular ornamentation, leaf types based on their adaxial-abaxial and crystal lines tructures in leaves were observed. Furthermore, an identification key was given based on anatomical features. Although anatomical features were generally similar, some of the characters varied among the species. According to the anatomical properties, C. persicus and C. glaucus were closely related to C. dentatus and C.tenuis, respectively, whereas C. lanatus was quite different from the others. © by PSP

    Determination of Some Seed Characteristics of False Flax (Camelina sativa L. Crantz) Genotypes Grown Under Semi-Temperate Conditions
    (Univ Philippines Los Banos, 2022) Subasi, Ilhan; Arslan, Yusuf; Eryigit, Tamer; Ciftci, Vahdettin; Camlica, Mahmut
    Camelina is an alternative low-input oil plant grown in marginal areas in Turkey. This study aimed to determine some quality characteristics of 39 camellia genotypes in ecological conditions in Bolu, Turkey. The field experiments were carried out in an augmented design with randomized blocks. In this work, some important properties such as thousand seed weight, oil content, fatty acid composition, and protein ratio were investigated. Results showed that mean data for thousand seed weight, oil ratio, and protein ratio were 0.63 - 1.5 g, 26.69 - 39.17%, and 21.81 - 29.81%, respectively. Considering the oil content of the genotypes used in the study, the PI 650158 genotype had the highest oil ratio, while the PI 650164 genotype had the highest seed protein ratio. In conclusion, the PI 311735 and PI 650158 genotypes were found to be within acceptable limits in terms of both oil and protein ratios in places with semi-temperate conditions.

    Yield and yield components of some advanced Camelina (Camelina sativa L. CRANTZ) genotypes in Bolu ecological conditions
    (2024) Arslan, Yusuf; Yasar, Mustafa; Isler, Berfin; Unal, Sefa; Subasi, Ilhan
    The negative effects of global warming are increasing worldwide and this increase is expected to continue. The camelina plant, which can be grown in marginal areas, stands out among other oilseed plants because it is drought-resistant and less costly. In the research, seeds belonging to 8 camelina genotypes, which were prominent in terms of oil rate, seed and oil yield, were used in the trial established in Bolu province, out of a total of 52 genotypes obtained from the seed bank of the United States Department of Agriculture, Agricultural Research Service and Germany. The study was conducted according to the Randomized Complete Block Design in Bolu Abant İzzet Baysal University, Faculty of Agriculture, Research and Application Field in the 2021-2022 production season. In the trait, each plot consisted of six rows with a row length of 3 m, a row spacing of 20 cm, and in row of 5 cm, with three replications. According to the research results; plant height 66.33-71.00 cm, number of branches 3.17-5.07 number plant-1, 1000 seed weight 1.10-1.24 g, seed yield 1095.4-1436.6 kg ha-1, oil content 36.63-40.37%, protein content 23.65-27.22%, oil yield 408.3-559.8 kg ha-1 and protein yield 279.0-391.3 kg ha-1. It was found that values between. According to the results obtained from the study, the K52 genotype in terms of seed yield, the K11 genotype in terms of oil rate and the K52 genotype in terms of protein rate came to the fore.
