Abstract:

Young stem sections with buds of Cercis canadensis ‘Forest Pansy’ were used as explants for experiment. The effects of culture mediums and PGRs such as 6-BA, NAA, IBA, TDZ on proliferation and rooting of test-tube plantlets were discussed. The results showed that the medium suitable for proliferation was DKW+TDZ 0.03 mg/L+PVP 0.5 mg/L, the optimum rooting medium was 1/2 MS+IBA 25 mg/L+AC 0.6 mg/L. In this system, the highest propagation coefficient was 4.27 and the rooting rate was 73.3%.
