Outline of Final Research Achievements |
Weed have diversity in their life-cycle (e.g. germination, flowering and seed dispersal) in same species. The objective of our research was to systematically explain that the diversity is adaptive to climate and human disturbance using three weeds (Echinochloa crus-galli, Setaria viridis and Digitaria ciliaris) we often see in ridge of paddy field. We clarify that the low germinate threshold temperature and vernalization response of seed were different among inter and intra local populations.
