Summary
A micropropagation method for Orthosiphon stamineus, using stem nodal segments, has been developed. The highest number of regenerated shoots was obtained on Murashige and Skoog (MS) medium supplemented with 6.7 μM benzyladenine with the formation of an average of 6.1 shoots per explant over a period of 4 wk. The number of shoots increased with longer culture duration on proliferation medium. Multiple shoots which were maintained on the proliferation medium for 6 wk had the highest proliferation rate. Separation of multiple shoots and culturing in larger flasks significantly promoted the growth and formation of plantlets. All the in vitro plantlets survived when transferred to the field and showed no significant morphological differences from the mother plants.
