Abstract:

Hibiscus hamabo with axillary bud stem segment was used as the test material. The effects of different disinfection treatments on explants and the effects of different plant growth regulators on axillary bud induction, proliferation culture and rooting culture were studied by tissue culture method. The results showed that the most suitable disinfection method for Hibiscus hamabo explants was 50% 84 disinfectant for 15 min, the contamination rate was 0, and the browning rate was 12.22%. The most suitable induction medium was MS+30 g·L-1 sucrose+7 g·L-1 agar+0.5 mg·L-1 6-BA+0.05 mg·L-1 NAA, and the germination rate was 88.89%. The most suitable medium for proliferation was MS+30 g·L-1 sucrose+7 g·L-1 agar+1.0 mg·L-1 6-BA+0.20 mg·L-1 NAA, and the proliferation coefficient was 2.01. The most suitable rooting medium was 1/2 MS+30 g·L-1 sucrose+7 g·L-1 agar+0.1 mg·L-1 IBA, and the rooting rate was 91.11%. In this study, a complete tissue culture and rapid propagation system of Hibiscus hamabo was established, which provided a reference for genetic transformation breeding and factory production of Hibiscus hamabo.
