Abstract: | Taro callus maintained on Knop's medium with 2, 0·2 or0·02 mg l1 2,4,5-trichiorophenoxyacetic acid (2,4,5-T)or Linsmaier-Skoog (LS) containing 1 mgl1 of the cytokininadenine-N-benzyl-9-tetrahydro-2H- pyran-2-yl (SD8339) or 6 dimethylaininopurineand 0·1 mgl1 -naphthaleneacetic acid underwenta transition to a stable organized growth form which is referredto as a calloid. On transfer to LS medium th 0·2 mgl12,4,5-T in the absence of cytokinin the calloid reverts backto callus.
