Abstract: Using yam bulbils for tuber propagation not only benefits the rejuvenation of Dioscorea opposita but also reduces the planting cost. Thus, conditions of the micro-tuber induction for the yams were studied. The shoot tips were cultured in MS medium with additions of varying concentrations of NAA/6-BA. Different treatments using NAA/KT, active carbon and sucrose were applied for the experimentation. The results indicated the optimal medium composition for the shoot tip induction to be: MS + 0.1 mgL-1 NAA+ 2.0 mgL-1 6-BA+ 0.2 gL-1 AC+ 30.0 gL-1 sucrose+ 8.0 gL-1 agar.The resultant plant regeneration rate was 91.7%. The optimal medium formula for the micro-tuber induction was: MS +0.1 mgL-1 NAA+ 1.0 mgL-1 KT+ 2.0 gL-1 AC+ 50.0 gL-1 sucrose+ 8.0 gL-1agar.The regenerated plants from the micro-tubers not only maintained the characteristics of the parent species but also improved its commercial appealing.
