In vitro induction of tetraploids in colchicine-treated cocoyam plantlets

  title={In vitro induction of tetraploids in colchicine-treated cocoyam plantlets},
  author={James T Tambong and Val T. Sapra and Stephen Garton},
Colchicine was applied in liquid B5 medium supplemented with 0.49 μm N6(δ2-isopentenyl)adenine to tissue culture derived cocoyam plantlets. Tetraploids (4n=52) and octoploid (8n=104) were produced by treating plantlets with 1.25 mM and 2.50 mM colchicine. Of all the plantlets treated with 1.25 mM or 2.5 mM, 16.7% and 20.0% respectively were mixoploids. These mixoploids were of the 2x-4x, 2x-4x-8x and 4x-8x types with 4x cells being dominant. Non-treated plantlets and plantlets treated with… CONTINUE READING
