Young leaves of Begonia rieger as explants ,callus inducing,proliferation of adventitious bud and rootage inducing were studied under culture media with different kinds and concentration of hormones . The results show ： MS ＋6-BA2. 0mg/L＋NAA 0. lmg/L is suitable for inducing callus and proliferation of adventitious bud, 1/2MS ＋ NAA 0. 2 mg/L is suitable for rootage.
