    Production of Biodiesel from in Vitro Grown Jojoba Calli Oil and a Comparison with Jojoba Biodiesel
    (2021) Ergün, Zeynep; Seri, Hasan; Aydın, Kadir; Büyükalaca, Saadet
    In this study, the fuel characteristics of biodiesel produced from jojoba [Simmondsia chinensis (Link)Schneider] oil and biodiesel obtained from the jojoba oil procured under laboratory conditions werecompared. For this purpose, jojoba seed endosperm and oil, which was attained from the jojobaendosperm calli via soxhlet extraction, was obtained. Biodiesel was produced from this oil via thetransesterification method. It was determined that the fuel characteristics of the biodiesels produced fromthe oil procured under the laboratory conditions and the oil attained from the seeds were close to eachother, and it was observed that the other features were in parallel with the standards, except for theviscosity and freeze point. This research study offers a solution for the raw material problem, which isone of the most important obstacles against the widespread use of biodiesel, in terms of environmentaland economic aspects.

    The Effect of Some Plant Growth Regulators on Callus Culture of Different Pistachio Varieties
    (2023) Bozkurt, Taner; Ergün, Zeynep
    Pistachio (Pistacia vera L) is one of the oldest cultivated plants in the world. Its fruits are rich in protein, minerals, carbohydrates, fiber, and vitamins. In addition, the demand for these plants is increasing due to the fact that they are very tasty and nutritious. On the other hand, pistachio cultivation is quite difficult. In addition, many problems are encountered in germination with seeds or reproduction with cuttings. These situations necessitate the development of different in vitro tissue culture protocols. In this study, callus culture optimization protocol was developed by using seeds of three different pistachio cultivars. Murashige and Skoog (MS) medium was supplemented with different concentrations of NAA, IAA, 2,4 D and BAP. When callus size (1,776 cm), callus weight (0.908 g) and embryogenic callus regenerations (27.94%) were considered, it was found that the best variety was Tekin. Again, in the evaluation made according to these factors, it was determined that the best improvement was in the MS medium containing 3 mg/L BAP and 1 mg/L 2,4D. The contamination rate detected throughout the studies ranged from 7.65% to 12.91%.
