Abstract:Tissue culture and rapid propagation of 9 cultivars of Dithenbachia were studied.The proliferation rates among the 9 varieties were quite different. Treatment with 3-5 mg L-1 6-BA was favorable for adventitious shoot induction and plant proliferation. Treatment on 1/2 MS medium with 0.5 mg L-1 NAA was best for rooting. A large scale production ofplantlets was established for 4 varieties, viz. D. maculata cv. Camilla, D. Maculata cv.Rudolph Roehrs, D. seguine cv. Wilson's Delight and D. amoena cv. Mars.
