| Research Abstract |
Dwarf bamboos have vigorous vegetative regeneration system in general. On the other hand, dwarf bamboos are monocarpic, which flower and fertilize seeds once and die in several decades. The genetic analysis revealed that these small-scale flowering was single genet flowerings. The results indicated that the dwarf bamboo species have self compatibility and the seeds showed the complete selfing. Several culms showed mixed mating system when they received outcross pollens, and these culms have outcrossing rates of 0.7.
