| Research Abstract |
Sasa, the dwarf bamboos, are long-lived monocarpic plants with vigorous rhizomatous vegetative reproduction for over 100 years. They often flower simultaneously in a wide range. It is a substantial question why bamboos flower to die simultaneously in a wide range although they can keep exclusive dominant populations with vegetative reproduction for a long period. In this research, we discussed the evolutionary trends of bamboo flowering habits from the viewpoint of genetic diversity, by analyzing the genetic structure of Sasa populations before and after mass flowering.
