100% root formation in in vitro cultures was observed regardless of kind and levels of auxin used and explant source. The number of roots/explant was increased in 0.5~1.0 mg/L IAA treatment. Thicker roots were observed with the addition of 9% sucrose compared with medium containing lower sucrose concentrations. Paclobutrazol and chlormequat had no effect on tuberization of formed roots but slightly increased the number of root. In in vivo rooting, soaking of regenerated shoot cuttings to 100 mg/L IBA for 15 to 60 minutes was found effective. Treatment of 0.1% IBA rooting powder and planting in rooting medium composred of vermiculite(1) : perlite(1) gave 100% rooting and survival.
