  • Biochemical characterization of micropropagated Ceratonia siliqua L. under effect of growth regulators and light quality

    • Authors: Gabr, Sawsan S. Sayed, A. M. M.;  Advisor: -;  Participants: Amin, Mona A.; Taha, Lobna S. (2020)

  • MS culture medium supplemented with BA produced the highest shootlets number/explants. For light quality, the data showed that green light increased shootlet number/explants, fresh and dry weights. However, yellow light increased shootlet length and leaves number and also caused significant increase in total phenols, flavonoids, and antioxidant capacity (DPPH) as compared to other lights. HPLC analysis showed that yellow light caused the highest accumulation of total phenolic and catechin that were the highest accumulated compounds (509 μg/ml) followed by that were accumulated under green light (412.68 μg/ml). Shootlets grown under white light (control) gave the highest accumulation o...

  • Correction to: In vitro bulb formation of direct and indirect regeneration of Lilium orientalis cv. “Starfighter” plants

    • Authors: Youssef, Nora M.;  Advisor: -;  Participants: Shaaban, Shimaa A.; Ghareeb, Zenna Fawzia; Taha, Lobna S. (2020)

  • For direct shoot organogenesis, culturing leaf explant on MS culture medium containing TDZ (0.5 mg/l) + 2,4-D (10 mg/l) led to the highest number of shootlets after 1 month. For indirect micropropagation, MS was supplemented with 2ip (0.5 mg/l) + picloram (5 mg/l)-induced callus tissues which were differentiated to embryos then weak shoots after 3 months. For more proliferation, the highest numbers of shootlets, leaves, and bulb scales were observed on MS culture medium supplemented with 1.0 mg/l of BA plus 0.2 mg/l NAA. Using 60 g/l of sucrose plus 3 or 6 mg/l of paclobutrazol led to the highest number of bulblets/explant for the third subculture. The highest bulblet diameters were r...
