ABSTRACT

<p><b>OBJECTIVE</b>To set up the fittest medium and optimum condition for leaves from Rehmannia glutinosa to form regenerated plantlets directly and to induce microtubers.</p><p><b>METHOD</b>Leaves of different phases obtained from the virus-free plantlets were incubated in some kinds of media on the back side.</p><p><b>RESULT AND CONCLUSION</b>The fittest medium for the formation of regenerated plantlet was MS + 6-BA 2.0 mg.L-1 and the fittest medium for the induction of microtuber was MS + 6-BA 1.0 mg.L-1 + NAA 0.5 mg.L-1. The optimum incubation temperaue was 25 degrees C and the light length was (2,000-3,000 lx) 12 h.d-1.</p>
