    • An
      in vitro method for the propagation of a
      Strelitzia species from a
      Strelitzia seed includes chemically scarifying the
      Strelitzia seed, and effecting surface sterilisation of the scarified seed. The scarified and sterilised seed is inoculated on germination media and allowed to germinate in darkness to establish a germinated seed culture. In a seedling development step, the germinated seed culture is subjected to light conditions for a suitable photoperiod for seedling development, whereafter a shoot explant is obtained by removing the root of the seedling. Apical dominance is uplifted in the shoot explant, and multiple shoot development is initiated on the shoot explant using plant growth regulators. The resulting multiple shoots are separated and axillary shoots subcultured to shoot induction media for further multiplication. Axillary shoots are transferred to root development media for inducing root growth, and hence plantlet regeneration. The resultant
      in vitro produced plantlets are acclimitised.
    • 一种用于从鹤望兰种子繁殖鹤望兰的体外方法包括化学scar the ia ia种子,并进行表面灭菌的划痕种子。 将经过清除和灭菌的种子接种在发芽培养基上,并在黑暗中发芽以形成发芽种子培养物。 在幼苗发育步骤中,将发芽的种子培养物进行光照条件以获得用于幼苗发育的合适的光周期,然后通过除去幼苗的根部获得芽外植体。 顶端优势在枝条外植体中提升,并且使用植物生长调节剂在枝条外植体上开始多次芽发育。 分离得到的多个芽,并将腋芽传代培养以诱导诱导培养基进一步繁殖。 将腋芽转移到根发育培养基以诱导根生长,并因此转移到小植株再生。 所得到的体外产生的小植物被驯化。
