Based on the tissue culture, the effect of N-phenyl-N＇-1,2,3-thiadiazol-5-ylurea, 6- benzyla minoprine（6-BA） and 1-Naphthylacetic acid on spore germination, protonema develop- ment and bud differentiation in Entodon challenged was investigated in this paper. The whole process was observed and taken pictures. The results show that TDZ, 6-BA and NAA have no significant effect on the spore germination. During the process of protonema development, 1.0 mg/L NAA can promote the primary development of protonema significantly, and 0.4 mg/L TDZ promotes branches formation in inter- mediate stage of the protonema development.
