  • Spathiphyllum floribundum cv. Cupid was micropropagated on LS medium containing various growth regulators. Shoot tips were cultured on media with different concentrations of thidiazuron (TDZ) or banzyladenine (BA). The medium containing 2.0 mg/L BA was most effective on the shoot multiplication and the formation of adventitious multi-shoot cluster from shoot tips among the different concentrations of TDZ and BA. The combined treatments of BA and paclobutrazol (PBZ) were stimulated the shoot multiplication and the formation of adventitious mu]ti-shoot clusters from shoot tips compared to the ones of BA alone. The adventitious multi-shoot clusters were culled with 5∼7 mm in size and cultured on media with BA or thidiazuron (TDZ). Shoot multiplication and shoot cluster proliferation from the shoot clusters were very favorable on media supplemented with 2.0∼3.0 mg/L BA. The shoots grew and rooted out vigorously on media with 2.0∼3.0 mg/L IBA. The rooted plantlets were acclimatized in the soil mixed with a rate of vermiculite 1 and perlite 1, and survived more than 95% in greenhouse.

  • In order to micropropagate uniform plantlets of Philodendron wend-imbe, the shoot tips were cultured on media supplemented with 0.5-10.0mg/L BA or 0.01-1.0 mg/L thidiazuron (TDZ). The multi-bud clusters from basal part of shoots formed vigorously on media containing 5.0-10.0 mg/L BA or 0.05-0.1 mg/L TDZ. Shoot formation from the bud cluster sections (5-7mm) was achieved favorably on medium with 5.0mg/L BA and 20 g/L sucrose. Lowering of sucrose in medium to 20 g/L was effective for the inhibition of callus growth from basal part of shoots. Growth of shoots and their rooting were favorable on media containing 1.0-2.0 mg/L IBA or 0.1mg/L NAA. The rooted plantlets were acclimatizated effectively in soil mixed with perlite 1: peat moss 1 or peat moss alone.
