영문 초록

To determine an optimum harvest time forchinese milk vetch (CMV) seed production, the seeds wereharvested at 4 times, according to 25, 30, 35, and 40 dayafter flowering (DAF), in Miryang, southern part of Korea.CMV plants were manually harvested at each time andseed threshing was done by rice threshing machine. Seedyield, 1,000-seed weight, germinability, and hard coat ratiowere investigated. Seed yield was the highest, 53.9 kg/300kg by dry weight (DW) of CMV plant, at 35 DAF. 1,000-seed weight increased according to seed harvest time from25 DAF to 40 DAF when it was 3.10 g. The germinationratios of seeds harvested at 4 times were not significantlylong period of CMV seeds stored, the seeds harvested latershowed higher germination rate. On the other hand, becausethe hard coat ratio causing germination inhibition was de-clined with an increase of storage period, it was higher inthe seeds harvested later. There was no difference amongthe seeds harvested at 4 times at October 1. In conclusion,it was presumed that an optimum harvest time for CMVseed production should be at 35 DAF considering sed yield,weight and germinability.
