| Abstract: | Cephalotaxus mannii Hook.f.(Cephalotaxus hainanensis Li) is a recalcitrant plant for in vitro culture due to its severe contamination,browning and slow growth.The young shoots of Cephalotaxus hainanensis Li cultivated in glasshouse were used as explants and the explants were sterilized in 70% ethanol for 1 min following with dipping in 0.1 %HgCl2 solution for 12 min and rinsed three times in sterilized water.In vitro response of explants was tested with different combinations of BA(6-benzylamino purine),NAA(naphthalene acetic acid) and 2,4-D(2,4-dichlorophenoxy acetic acid).The optimum effect of callus induction was obtained in the medium of MS + 0.5 mg/L NAA + 0.5-1.0 mg/L BA + 2.5-4.0 mg/L 2,4-D. |
