This study was conducted to determine  the effect of growth hormones and mycorhyza application on the growth of ramin cuttings.  A Completely Randomized Design with 5 replicates was used in this study. The experiment consisted of two stages  i.e  hormon treatments (control, Rapid root, Root Up, IBA 250 mg/l, IBA 500 mg/l, IBA 1000 mg/l), Fusarium and mycorhyza applications. The result showed that  the highest number of root  was obtained from Root Up (12,83 cm),  while the lowest was from Fusarium treatments (4,67 cm). IBA 250 mg/l enhanced the number of roots and the length of root significantly  but not stimulate the development of  new leaf.  While mycorhyza application improving  the growth of the new leaf  and  the root development of ramin.
