The objective of this study was to investigate the variation of Chinese milk vetch (Astragalus sinicus L.; CMV) seed quality after flowering. We tagged individual open flowers of CMV at the day of maximum flowering (11 May) in Seoul, Korea. Seed samples were harvested serially at 15, 20, 25 and 30 days after flowering (DAF). To compare with dried seeds, non-dried seeds were tested immediately after harvest and the remaining seeds were placed at room temperature for 4 weeks. Seed length, 1000 seed weight, moisture content, germination rate (GR), mean germination time (MGT), germination speed (GS), germination performance index (GPI) and physical dormancy rate (PDR) were investigated.
