The explants of 0.5 cm showed high rate of morphogenic response (44.44%) due to its highest survival rate. Meanwhile 1.0 cm long explants exhibited low morphogenic response of 11.11% compared to 0.5 cm long one. There was more root organogenesis in the cultured rhizome buds
(1.0 cm long) at the 6 th week of culture (Figure 3B). There was no morphogenic response in explants of 2.0 cm length as all the cultured explants were contaminated at the 6 th week of culture
