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.

矮秆竹一般具有旺盛的营养体再生系统。另一方面，矮竹是一次结实的，花和受精种子一次，几十年后死亡。遗传分析表明，这些小规模开花是单基株开花。结果表明，矮秆竹种具有自交亲和性，种子表现为完全自交。有几个秆在接受异交花粉时表现为混合交配系统，异交率为0.7。
