OBJECTIVE: To study the morphogenesis in formative process of tuberous root in vitro from Rehmannia glutinosa and compare the anatomical shape of tuberous root with nature term R. glutinosa. METHOD: Tuberous roots of different vegetal phase were cut and dyed, then made into paraffin cuts and observed microscope. RESULT AND CONCLUSION: In anatomical shape, nature R. glutinosa and tuberous root were the same, which showed that no structural variation occurred in tuberous root induced process.
