Some of Musa cultivars were used in this study: Cauman (AA), Giahuong (AAA), Su (AAB) and Hot (BB). Auxins (IAA, NAA, or 2,4-D at different concentrations) were used to induce adventitious rooting from explants containing a apical shoot and young leaves. Histological changes in the rooting were analysed under microscope. This process included following stages: activation of cell divisions, initiating of meristematic region, formation of root primordium, and root elongation. Roles of genotypes, plant growth regulators in this adventitious rooting were discussed.
