Prelim inary study on the tissue culture of Heptacodium miconioides Rehd

The media of tender leaves-induced callus and cal1us-induced buds were screened and the effects of Mo,Mn and some plant hormones on cutting production of Heptacodium miconioides were analyzed． The results show that tender leaves are more beneficial to callus inducement than buds and MS+0．5mg／kg2．4-D+lmg／kglBA+0．5mg／kgZT+lg／kg active carbon is the most advantageous medium to callus inducement：1／2 MS+2mg／kg6-BA+0．2mg／kgNAA is the most profitable medium to buds induction；trea tment of 6-BA is the most useful to cutting production.
