Abstract:

As a wild banana resource, Musa velutina can be regarded as an important genetic and breeding resource and has an ornamental value. In this study, the tissue culture and rapid propagation technology of Musa velutina were studied using the hopson flowers as the plant materials. Callus could be induced by the callus induction medium. The best bud differentiation medium was MS+6-BA (3.0 mg/L)+NAA (0.1-0.2 mg/L), the best bud proliferation medium was MS+6-BA (2.0 mg/L)+NAA (0.1 mg/L), and the best rooting medium was MS+IBA (3.0 mg/L)+NAA (0.3 mg/L). It took about 100 d from sampling to obtaining tissue culture seedlings with complete root system, and the reproduction efficiency was more than 100 plants/flower bud.

Key words: Musa velutina, hopson flowers, tissue culture, bud differentiation, bud proliferation
