he F1 hybrid seeds of Den. nobile♀ × Den. moniliforme♂ were taken as materials to explore in vitro rapid propagation techniques and flowering. The results showed that the optimum media for seedlings germination was 1/2MS + 6-BA 1.0 mg·L-1 + NAA 2.0 mg·L-1+ IBA 2.0 mg·L-1+ banana mud 100 g·L-1. The optimum medium for proliferation of subculture was 1/2MS + 6-BA 0.2 mg·L-1+ NAA 1.0 mg·L-1 + banana mud 100 g·L-1 with the proliferation coefficient of 4—5 times. The medium for regeneration of adventitious buds was 1/2MS + 6-BA 2.0 mg·L-1+ NAA 0.2 mg·L-1+ peptone 2 g·L-1 with 93.3% induction rate and 3.7 times induction coefficient. The rooting medium was TH + 6-BA 0.5 mg·L-1+ NAA 1.0 mg·L-1, the rooting rate was up to 91.7% with 3—5 roots. The medium for the floral bud induction was 6-BA 2.0 mg·L-1 + NAA 0.5 mg·L-1 + IBA 0.5 mg·L-1 with the rate of 8%.
