Abstract
Curcuma xanthorrhiza and Zingiber aromaticum, are important medicinal species of the Zingiberaceae family. They are used in traditional medicine known as Jamu. This study reports on the presence of sucrose and BA (benzylaminopurine) supplements in the culture medium and also the effect of varying culture condition on In vitro propagation of these two species. Murashige & Skoog (MS) medium supplemented with 5 mg L-1 BA and 30 g L-1 sucrose, incubated under total darkness, induced the highest number of multiple shoots in C. xanthorrhiza while the Z. aromaticum produced the highest number of multiple shoot in the same medium incubated under continuous light. The increase in sucrose concentration reduced shoot height in both species. Rooting of micro-shoots was not affected by the different culture treatments. The acclimatized plantlets of C. xanthorrhiza and Z. aromaticum were normal with 83.3-100% percentage when transferred to the outside environment.
