  • The highest amounts of scopoletin 57.08, 26.42, and 25.30 (μg/g DW) were detected using reversed phase of high-performance liquid chromatography (RP-HPLC) in leaves extract of intact plant followed by regenerated and calli cultures of internod explants, respectively. This study is the first record for in vitro propagation and production of secondary metabolites from Diospyros kaki L. using biotechnology techniques. Chemical anaysis were carried out using HPLC technique.

    • Authors: Taha, Hussein;  Advisor: -;  Participants: Ghazy, Usama Mohamed; Gabr, Ahmed Mohamed Magdy; EL-Kazzaz, Ahmed Ahmed Ahmed; Ahmed, Eman Abdel Mottaleb Mahmoud; Haggag, Karima Mohamed (2020)

  • A simple and efficient protocol for in vitro propagation of different varieties of Morus alba (yue 11, sha 2x lun 109, morittina, kokuso 27, and kantava 2) was established. Sterilization of shoot tips and auxiliary buds with 0.2% of mercuric chloride (MC) for 10 min was the best to get sterilized and survival explants. In vitro mulberry multiplication of yue 11, sha 2x lun 109, morittina, kokuso 27, and kantava auxiliary buds cultured on the MS medium fortified with 1.5 mg/l BA gave the best results of the multiplication rates, maximum number of shoots/explant, and highest shoot length (cm), respectively. Moreover, culturing of derived mulberry shoots on the MS medium supplemented wit...
