영문 초록

This study was conducted to confirm the germinability of unripened seeds for rapid generation advancement of soybean in field and greenhouse. Seed development and germinability were faster in greenhouse than in field, and in the early variety than in the late variety. The first germinabilities were found on the 20 days after flowering(DAF) in greenhouse materials, and on the 20 to 25 DAF in field materials. It was found that over 90 percentage of germination on 10 to 20 days before maturity of soybean in field and greenhouse, and this ripening stage was corresponded with the time when the fresh pod weight reached at the highest level. The germination ratio of the seeds dried with pod shell was the almost same level with that of the fresh seeds ripened for 10 to 15 days more. The germination ratios of the dried seeds which were harvested on 20 to 25 days before maturity in each cultivar were over 80 percentage.
