title: [Effects of culture conditions on callus growth and taxol formation of Taxus yunnanensis Cheng et L.K.Fu].
abstract: OBJECTIVE
  To seek culture conditions suitable for the callus growth and taxol formation of Taxus yunnanensis.
  
  
  METHODS
  Determining the growth index and taxol content in the callus cultured under different illumination conditions or on different media.
  
  
  CONCLUSIONS
  Darkness, the combination of 0.1 mg.L-1BAP and 2,4-D 1.0 mg.L-1, and B5, DCR or 6,7-V basal medium were favorable for the callus growth and taxol formation of Taxus yunnanensis; high NO3- concentration in the medium promoted callus growth, and high NH4+ concentration greatly inhibited callus growth, but dramatically increased taxol content.
