Abstract: Contrasting of beautiful deep red-purple bract with yellow inflorescence, Globba siamensis Hemsl. was selected for a new coming potted ornamental. In order to become a new economic plant, a large amount of plants are required to supply the demand of customers. At present study, the appropriate medium for mass propagation in vitro was investigated. Leafy-shoot base segments used as explant, at the length of 1.5 cm, was excised from in vitro 5-6 cm high G. siamensis plantlets. The explants were cultured on MS agar medium supplemented with 0, 1, 2, 4 and 8 mg/L N6 -benzyladenine (BA) for 8 weeks before transferring to MS agar medium for 4 weeks. The highest number of new leafy-shoots and roots per explant (24.1 and 180.4, respectively) were obtained on MS agar medium supplemented with 2 mg/L BA. However, new leafy-shoot plantlets which cultured on MS agar medium supplemented with 1 mg/L BA was the highest (20.65 cm). No significant difference of root length was found among plantlets that cultured on MS supplemented with 1-4 mg/L BA.
